Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a method and apparatus for transmitting bandwidth information, a communication network, a device, and a storage medium. Background Art

[0002] With the gradual increase in the demand for network intelligence and the development of bandwidth resource reservation technologies such as Flexible Ethernet (FlexE) and channelized sub-interfaces, it has become increasingly important for network operators to obtain the bandwidth usage of forwarding links in the network, whether from the perspective of operation and maintenance management or business requirements. In related technologies, network element devices (such as routers, switches, etc.) in the network can upload bandwidth information to the network control system through a transmission protocol, and then the network control system determines the bandwidth usage based on the bandwidth information uploaded by the network element devices. However, the bandwidth information transmitted by the current transmission protocol is mainly the bandwidth information of neighbor links established based on Intermediate System to Intermediate System (ISIS) or Open Shortest Path First (OSPF), and this bandwidth information is usually numerical data, such as an absolute value in Byte / s. The network control system needs to perform multi-dimensional combined calculations to evaluate the link status. It can be seen that the bandwidth information transmitted by network element devices in the current network has the problem of being unable to intuitively present the link bandwidth usage, resulting in an inability to meet the requirement for obtaining the link bandwidth usage.

[0039] In order to enable those skilled in the art to better understand the technical solutions in the present application, the following will clearly and completely describe the technical solutions in the present application with reference to the drawings in one or more embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0040] The terms "first", "second", etc. in the present application and the claims are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the present application can be implemented in an order other than those illustrated or described herein. In addition, "and / or" in the present application and the claims means at least one of the connected objects, and the character " / " generally means that the associated objects before and after are in an "or" relationship.

[0041] Figure 1 It is a schematic communication network diagram provided by an embodiment of the present application. Figure 1The communication network shown includes a network control system and multiple network element devices R1, R2, R3, R4, and R5. Each network element device can provide network services for users. The network control system is connected to the multiple network element devices through a network, and the network control system can manage and control the multiple network element devices. Among them, the network element device can be a switch or a router, etc.

[0042] Based on the technical solution provided in the embodiment of the present application, link quality detection can be deployed among the network element devices in the Figure 1 shown network. Each network element device can obtain the bandwidth information of the link with its neighbor device. The bandwidth information includes at least one of bandwidth utilization information, packet error information, and packet loss information. After obtaining the bandwidth information, the network element device can flood the bandwidth information in the network, and then one of the network element devices aggregates the bandwidth information of all links and reports it to the network control system. After receiving the reported bandwidth information, the network control system can determine the bandwidth usage of each link. Compared with the bandwidth information transmitted by the network element device in the prior art, the bandwidth information transmitted in the embodiment of the present application is richer, so that the usage situation of the link bandwidth can be presented intuitively. Further, the bandwidth information transmitted by the network element device can be two-way bandwidth information. Therefore, the number of link bandwidth information flooded in the network can be effectively reduced, and the network burden can be alleviated.

[0043] Figure 1 When the shown network element device transmits bandwidth information, it can use the extended protocol for transmission. The extended protocol can be a protocol obtained by extending the existing transmission protocol. The extension of the existing protocol is specifically to add a message format for supporting bandwidth information transmission in the existing protocol. Thus, the effective transmission of bandwidth information can be realized.

[0044] It should be noted that in practical applications, the number of network element devices included in the communication network can be any integer greater than or equal to 2, Figure 1 and only the case where the communication network includes 5 network element devices is taken as an example for illustration. In addition, the connection manner between the multiple network element devices can also be Figure 1 other connection manners other than the shown connection manner, and no specific limitation is made here.

[0045] The following will describe in detail the technical solutions provided in each embodiment of the present application with reference to the accompanying drawings.

[0046] Figure 2 is a schematic flowchart of a method for transmitting bandwidth information according to an embodiment of the present application. Figure 2 The shown method for transmitting bandwidth information can be executed by a first device, and the first device can be Figure 1 any one of the shown network element devices. Figure 2 The shown method for transmitting bandwidth information is described as follows.

[0047] S202: Obtain the bandwidth information of the link. The link is the communication link between the first device and the adjacent second device. The bandwidth information includes at least one of bandwidth utilization information, packet error information, and packet loss information.

[0048] During the process of providing network services, the first device can obtain the bandwidth information of the communication link with its neighbor device. Here, for the sake of easy distinction, the neighbor device of the first device can be represented as the second device, and the number of second devices can be one or more. When the first device obtains the bandwidth information, it can obtain the bandwidth information of the link with each second device. The bandwidth information can be information that can intuitively present the bandwidth usage of the link. Specifically, the bandwidth information can include at least one of bandwidth utilization information, packet error information, and packet loss information.

[0049] It should be noted that the bandwidth information obtained by the first device can be statistically obtained based on the output and input of the interface on the first device. The embodiments of the present application do not focus on how to statistically obtain the bandwidth information, that is, do not care about the source of the bandwidth information, but only focus on the transmission of the bandwidth information in the network.

[0050] Optionally, in some embodiments, the bandwidth utilization information in the bandwidth information can include at least one of the outbound bandwidth utilization and the inbound bandwidth utilization. The packet error information can include at least one of the inbound packet error statistics and the outbound packet error statistics. The packet loss information can include at least one of the inbound packet loss statistics and the outbound packet loss statistics. Among them, outbound and inbound are related to the flow direction of the traffic carried by the link. For example, devices R1 and R2 are directly connected. For R1, outbound can be that the traffic flows out from R1 to R2, and inbound can be that the traffic flows in from R2 to R1. In the case where the bandwidth information is two-way bandwidth information, compared with one-way bandwidth information, it can effectively reduce the number of link bandwidth information flooded in the network, thereby reducing the network burden.

[0051] For a link, the outbound bandwidth utilization rate of the link can be the ratio of the outbound used bandwidth of the link to the outbound bandwidth. The outbound bandwidth can be the sum of the outbound remaining bandwidth and the outbound reserved bandwidth. The outbound reserved bandwidth can be 0 or non-zero. There can be one or more outbound traffic carried on the link. In the case where the link carries multiple outbound traffic, the outbound used bandwidth of the link can be the sum of the bandwidths occupied by the multiple outbound traffic. Similarly, the inbound bandwidth utilization rate of the link can be the ratio of the inbound used bandwidth of the link to the inbound bandwidth. The inbound bandwidth can be the sum of the inbound remaining bandwidth and the inbound reserved bandwidth. The inbound reserved bandwidth can be 0 or non-zero. There can be one or more inbound traffic carried on the link. In the case where the link carries multiple inbound traffic, the inbound used bandwidth of the link can be the sum of the bandwidths occupied by the multiple inbound traffic.

[0052] Optionally, in some embodiments, the outbound bandwidth utilization rate and the inbound bandwidth utilization rate can be real-time bandwidth utilization rates, that is, the bandwidth utilization rate information can be the real-time bandwidth utilization rate information of the link. In other embodiments, the outbound bandwidth utilization rate and the inbound bandwidth utilization rate can also be the average values of the bandwidth utilization rates within a certain time period, that is, the bandwidth utilization rate information can be the average values of the bandwidth utilization rates within a certain time period. Here, for the sake of easy distinction, the time period corresponding to the inbound bandwidth utilization rate can be expressed as the first time period, and the time period corresponding to the outbound bandwidth utilization rate can be expressed as the second time period. Both the first time period and the second time period can be determined according to actual service requirements and are not specifically limited here. By flexibly setting the first time period and the second time period, the update rates of the inbound bandwidth utilization rate and the outbound bandwidth utilization rate can be flexibly adjusted.

[0053] Optionally, the above-mentioned first time period can be equal to the second time period. For example, the outbound bandwidth utilization rate and the inbound bandwidth utilization rate can be the average values of the outbound bandwidth utilization rate within 5 minutes and the average values of the inbound bandwidth utilization rate within 5 minutes.

[0054] For a link, the inbound error packet statistics and outbound error packet statistics of the link can be real-time data of the current statistics and are a statistical value. In some embodiments, the outbound error packet statistics at one end of the link are equal to the inbound error packet statistics at the other end of the link, and the inbound error packet statistics at one end of the link are equal to the outbound error packet statistics at the other end of the link. In other embodiments, the outbound error packet statistics at one end of the link may not be equal to the inbound error packet statistics at the other end, and / or the inbound error packet statistics at one end of the link are not equal to the outbound error packet statistics at the other end. This is because new error packets may be generated during the forwarding process due to different transmission methods and other reasons, resulting in different error packet statistics at both ends of the link. In this case, there will be two sets of inbound error packet statistics and / or two sets of outbound error packet statistics for the link. In order to better reflect the error packet situation of the link, when obtaining the inbound error packet statistics of the link, if there are two sets of inbound error packet statistics for the link, the maximum value of the two sets of inbound error packet statistics can be used as the final inbound error packet statistics of the link. Similarly, when obtaining the outbound error packet statistics of the link, if there are two sets of outbound error packet statistics for the link, the maximum value of the two sets of outbound error packet statistics can be used as the final outbound error packet statistics of the link. For example, if devices R1 and R2 are directly connected, the number of outbound error packets counted by device R1 is 100, and the number of inbound error packets is 150. The number of outbound error packets counted by R2 (which is the inbound error packet number relative to R2) is 120, and the number of inbound error packets (which is the outbound error packet number relative to R2) is 110. Then the error packet information of the link between R1 and R2 can be: the outbound error packet statistics are 120, and the inbound error packet statistics are 150.

[0055] For a link, the inbound packet loss statistics and outbound packet loss statistics of the link can be real-time data of the current statistics, which is a statistical value. In some embodiments, the outbound packet loss statistics at one end of the link are equal to the inbound packet loss statistics at the other end of the link, and the inbound packet loss statistics at one end of the link are equal to the outbound packet loss statistics at the other end of the link. In some other embodiments, the outbound packet loss statistics at one end of the link may not be equal to the inbound packet loss statistics at the other end, and / or the inbound packet loss statistics at one end of the link are not equal to the outbound packet loss statistics at the other end. This is because new packet losses may occur during the forwarding process due to different transmission methods and other reasons, resulting in different packet loss statistics at both ends of the link. In this case, there will be two sets of inbound packet loss statistics and / or two sets of outbound packet loss statistics for the link. In order to better reflect the packet loss situation of the link, when obtaining the inbound packet loss statistics of the link, if there are two sets of inbound packet loss statistics for the link, the maximum value of the two sets of inbound packet loss statistics can be used as the final inbound packet loss statistics of the link. Similarly, when obtaining the outbound packet loss statistics of the link, if there are two sets of outbound packet loss statistics for the link, the maximum value of the two sets of outbound packet loss statistics can be used as the final outbound packet loss statistics of the link. For example, if devices R1 and R2 are directly connected, the number of outbound packet losses counted by device R1 is 200, and the number of inbound packet losses is 150. The number of outbound packet losses counted by R2 (which is the inbound packet loss number relative to R2) is 180, and the number of inbound packet losses (which is the outbound packet loss number relative to R2) is 190. Then, the packet loss information of the link between R1 and R2 can be: the outbound packet loss statistics are 200, and the inbound packet loss statistics are 190.

[0056] S204: Transmit the bandwidth information through the first transmission protocol. The first transmission protocol includes a first message format, and the first message format is used to support the transmission of the bandwidth information.

[0057] After obtaining the bandwidth information, the first device can transmit the bandwidth information. When the first device transmits the bandwidth information, it needs to use a transmission protocol for transmission. Considering that the bandwidth information transmitted by the existing transmission protocol is different from the bandwidth information transmitted in the embodiments of the present application, the existing transmission protocol may not support the transmission of the bandwidth information in the embodiments of the present application. Therefore, when the first device transmits the bandwidth information, it may not use the existing transmission protocol for transmission, but use the first transmission protocol for transmission. The first transmission protocol includes a first message format, and the first message format supports the transmission of the bandwidth information in the embodiments of the present application, thereby enabling the effective transmission of the bandwidth information.

[0058] The first transmission protocol may be a protocol obtained by extending an existing transmission protocol. Optionally, in some embodiments, the first transmission protocol may be a protocol obtained by adding a first message format to the Intermediate System to Intermediate System (ISIS) protocol, or a protocol obtained by adding a first message format to the Open Shortest Path First (OSPF) protocol, or a protocol obtained by adding a first message format to the Border Gateway Protocol (BGP). Among them, the first message format added to the ISIS protocol, OSPF protocol, and BGP protocol may be represented as a TLV or a Sub-TLV.

[0059] The first message format may have one or more formats. Specifically, when the bandwidth information is any one of bandwidth utilization information, packet error information, and packet loss information, the first message format may have one format, and the message of this format is used to support the transmission of one type of bandwidth information. For example, if the bandwidth information is bandwidth utilization information, the first message format has one format, and the message of this format is used to support the transmission of bandwidth utilization information. When the bandwidth information includes at least two of bandwidth utilization information, packet error information, and packet loss information, the first message format may have at least two formats, and messages of different formats are used to support the transmission of different bandwidth information. For example, when the bandwidth information includes bandwidth utilization information, packet error information, and packet loss information, the first message format may include three formats. The first format of the message is used to support the transmission of bandwidth utilization information, the second format of the message is used to support the transmission of packet error information, and the third format of the message is used to support the transmission of packet loss information.

[0060] In some embodiments, the first message format for supporting the transmission of bandwidth utilization information may include at least one of a type field, a valid value field, an exception setting field, a traffic type field, a reserved field, an inbound link bandwidth utilization field, and an outbound link bandwidth utilization field. Taking the first message format including these 7 fields: type field, valid value field, exception setting field, traffic type field, reserved field, inbound link bandwidth utilization field, and outbound link bandwidth utilization field as an example, the corresponding field format design may be as Figure 3 shown.

[0061] Figure 3 In it, the meanings of each field are as follows:

[0062] (1) Type field: Type, Type = TBD1 (To Be Determined 1) indicates carrying inbound bandwidth utilization information and outbound bandwidth utilization information;

[0063] (2) Valid value field: Length, which represents the number of bytes of the valid value field and can be 8;

[0064] (3) Abnormal setting field: A. When A is set, it indicates data abnormality (such as the bandwidth utilization rate exceeding 100%) or non-statistics;

[0065] (4) Traffic type field: V, which can represent different types through 2 bits. For example, 00 indicates statistics without distinguishing packet types, 01 represents only IPv4 statistics, 10 represents only IPv6 statistics, and 11 is a reserved value;

[0066] (5) Reserved field: Reserve, which is all 0;

[0067] (6) Link inbound bandwidth utilization field: Input Utilization, which represents the link inbound bandwidth utilization. It can include 16 bits, support valid values from 0 to 10000, and its unit is 1 / 10000. That is, when the filled value of this field is 1234, it means the current inbound bandwidth utilization is 12.34%. If the data in this field is greater than 10000, it is considered invalid information;

[0068] (7) Link outbound bandwidth utilization field: Output Utilization, which represents the link outbound bandwidth utilization. It can also include 16 bits, support valid values from 0 to 10000, and its unit is 1 / 10000. That is, when the filled value of this field is 1234, it means the current outbound bandwidth utilization is 12.34%. If the data in this field is greater than 10000, it is considered invalid information.

[0069] In some embodiments, the first packet format for supporting the transmission of mispacket information may include at least one of a type field, a valid value field, an abnormal setting field, a reserved field, a link inbound mispacket statistics field, and a link outbound mispacket statistics field. Taking the first packet format including these 6 fields: type field, valid value field, abnormal setting field, reserved field, link inbound mispacket statistics field, and link outbound mispacket statistics field as an example, the corresponding field format design can be as Figure 4 shown.

[0070] Figure 4 Among them, the meanings of each field are as follows:

[0071] (1) Type field: Type, where Type = TBD2 (to be determined 2) indicates carrying link outbound mispacket statistics information and inbound mispacket statistics information;

[0072] (2) Valid value field: Length, which represents the number of bytes of the valid value field and can be 8;

[0073] (3) Abnormal Set Field: A. When A is set, it indicates that the error packet count has exceeded the maximum value that Error Packets can represent, or the error packets are not counted at this time.

[0074] (4) Reserved Field: Reserved, all bits are 0.

[0075] (5) Link Input Error Packet Count Field: Input Error Packets, which represents the link input error packet count. It can represent valid values from 0 to 65535 through 16 bits. When the value is 4321, it means the number of input error packets is 4321.

[0076] (6) Link Output Error Packet Count Field: Output Error Packets, which represents the link output error packet count. It can also represent valid values from 0 to 65535 through 16 bits. When the value is 4321, it means the number of output error packets is 4321.

[0077] In some embodiments, the first packet format for supporting the transmission of packet loss information may include at least one of a type field, a valid value field, an abnormal set field, a reserved field, a link input packet loss count field, and a link output packet loss count field. Taking the first packet format including these 6 fields: type field, valid value field, abnormal set field, reserved field, link input packet loss count field, and link output packet loss count field as an example, the corresponding field format design can be as Figure 5 shown.

[0078] Figure 5 In, the meanings of each field are as follows:

[0079] (1) Type Field: Type. Type = TBD3 (To Be Determined 3) represents carrying the link input packet loss information and output packet loss information.

[0080] (2) Valid Value Field: Length, which represents the number of bytes of the valid value field and can be 8.

[0081] (3) Abnormal Set Field: A. When A is set, it indicates that the packet loss count has exceeded the maximum value that Discard Packets can represent, or the packet loss is not counted at this time.

[0082] (4) Reserved Field: Reserved, all bits are 0.

[0083] (5) Link Input Packet Loss Count Field: Input Discard Packets, which represents the link input packet loss count. It can represent valid values from 0 to 65535 through 16 bits. When the value is 4321, it means the number of input packet losses is 4321.

[0084] (6) Link output discard packet statistics field: Output Discard Packets, which represents the link output discard packet statistics. It can represent valid values from 0 to 65535 through 16 bits. When the value is 4321, it means the number of input discard packets is 4321.

[0085] In practical applications, to support the transmission of different bandwidth information, preferably, the first packet format can have the above three formats to support the transmission of three different bandwidth information. Correspondingly, when expanding the existing transmission protocol, three new packet formats can be added to the existing transmission protocol. For example, when expanding the existing ISIS protocol, the above three Sub-TLVs can be added to Extended IS Reachability TLV (type 22), Inter-AS Reachability TLV (type 141), and MT-ISN TLV (type 222) respectively, where the Type value of the corresponding Sub-TLV is to be determined. When expanding the OSPF protocol, the above three Sub-TLVs can be added to Link TLV, where the Type value of the corresponding Sub-TLV is to be determined. When expanding the BGP protocol, the above three BGP-LS Link Attribute TLVs can be directly added, where the Type value of the corresponding TLV is to be determined.

[0086] When the first device transmits bandwidth information through the first transmission protocol, optionally, in some embodiments, the bandwidth information can be flooded in the communication network through the first transmission protocol to transmit the bandwidth information to other network element devices in the communication network, and then the other network element devices report the bandwidth information to the network control system so that the network control system can obtain the bandwidth usage of the link between the first device and its neighbor devices. In other embodiments, the first device can also directly report the bandwidth information to the network control system through the first transmission protocol. In this way, the network control system can directly obtain the bandwidth usage of the link between the first device and its neighbor devices from the first device.

[0087] When the first device transmits bandwidth information to the network control system through the first transmission protocol, optionally, the following steps can also be included:

[0088] Receive the bandwidth information of other links in the communication network;

[0089] Transmit the bandwidth information of other links to the network control system through the first transmission protocol.

[0090] The bandwidth information of other links can be statistically obtained by the network element devices corresponding to the other links and transmitted to the first device in a flooding manner. The bandwidth information of other links includes at least one of bandwidth utilization information, packet error information, and packet loss information. The bandwidth utilization information includes at least one of outbound bandwidth utilization and inbound bandwidth utilization. The packet error information includes at least one of inbound packet error statistics and outbound packet error statistics. The packet loss information includes at least one of inbound packet loss statistics and outbound packet loss statistics. For specific details, reference can be made to the explanation of the bandwidth information obtained by the first device in S202 above, which will not be repeated here.

[0091] After receiving the bandwidth information of other links transmitted by other network element devices, the first device can report the bandwidth information of other links to the network control system through the first transmission protocol, so that the network control system can obtain the bandwidth usage of other links. Among them, when the first device reports the bandwidth information of other links to the network control system, it can report these bandwidth information and the bandwidth information obtained by the first device in S202 to the network control system together, so as to reduce the number of information reports. In addition, in the case where the first device reports the bandwidth information of other links, other network element devices do not need to report these bandwidth information to the network control system to avoid duplicate reporting.

[0092] In practical applications, after each device in the communication network obtains the bandwidth information of the link with its neighbor device, it can flood the bandwidth information in the network and then randomly select one device to report all the bandwidth information of the links to the network control system. Alternatively, it can also be pre-agreed that a certain device is the reporting device for bandwidth information. After obtaining the bandwidth information of the link with its neighbor device, the reporting device does not need to flood in the network. At the same time, after other network element devices obtain the bandwidth information of the link with their neighbors, they can flood in the network to transmit the link information to the reporting device. After receiving the bandwidth information of other links, the reporting device can report these bandwidth information and the bandwidth information obtained by the reporting device to the network control system together.

[0093] When the first device transmits bandwidth information through the first transmission protocol, optionally, in some embodiments, it may include the following steps:

[0094] Determine whether the bandwidth information meets the transmission conditions. The transmission conditions include that the transmission function of the first transmission protocol for the bandwidth information is in an enabled state, or the transmission function of the first transmission protocol for the bandwidth information is in an enabled state and the change amount of the bandwidth information exceeds a preset threshold;

[0095] When the bandwidth information meets the transmission conditions, transmit the bandwidth information through the first transmission protocol.

[0096] The first transmission protocol can support the enabling and disabling capabilities of the bandwidth information transmission function. When the transmission of bandwidth information is allowed, the first transmission protocol can enable the transmission function of bandwidth information. When the transmission of bandwidth information is not allowed, the first transmission protocol can disable the transmission function of bandwidth information. In this way, before transmitting bandwidth information, the first device can determine whether the transmission function of the first transmission protocol for bandwidth information is in the enabled state. If it is in the enabled state, the first device can transmit bandwidth information. If it is not in the enabled state, that is, in the disabled state, the first device can refrain from transmitting bandwidth information. Alternatively, the first device can also determine whether the transmission function of the first transmission protocol for bandwidth information is in the enabled state and whether the change amount of the bandwidth information exceeds a preset threshold. If it is in the enabled state and the change amount of the bandwidth information exceeds the preset threshold, the first device can transmit bandwidth information. If it is not in the enabled state or the change amount of the bandwidth information does not exceed the preset threshold, the first device can refrain from transmitting bandwidth information. Among them, the preset threshold can be set according to actual service requirements and is not specifically limited here. By flexibly setting the preset threshold, the reporting frequency of bandwidth information can be flexibly adjusted.

[0097] Since the transmission conditions can be set and the first device will only transmit bandwidth information through the first transmission protocol when the transmission conditions are met, it is possible to avoid the device from frequently updating bandwidth information and reduce the flooding of bandwidth information update announcements in the network.

[0098] Optionally, in some embodiments, the first transmission protocol can support the unified enabling or disabling of the transmission functions of different bandwidth information. For example, it can uniformly enable or disable the transmission functions of bandwidth utilization information, packet error information, and packet loss information. In the case of unified enabling or disabling, the first device can transmit or refrain from transmitting different bandwidth information simultaneously. In other embodiments, the first transmission protocol can support the independent enabling or disabling of the transmission functions of different bandwidth information. For example, the first transmission information can support the independent enabling and disabling of the transmission function of bandwidth utilization information, the independent enabling and disabling of the transmission function of packet error information, and the independent enabling and disabling of the transmission function of packet loss information. In the case of independent enabling or disabling, the first device can transmit or refrain from transmitting different bandwidth information separately, so that the flexible transmission of different bandwidth information can be achieved.

[0099] The bandwidth information may include at least one of outbound bandwidth information and inbound bandwidth information. Among them, when the bandwidth information includes both outbound bandwidth information and inbound bandwidth information, the change amount of the bandwidth information exceeding the preset threshold may be that the change amount of the outbound bandwidth information exceeds the preset threshold or the change amount of the inbound bandwidth information exceeds the preset threshold. That is, when the change amount of at least one of the outbound bandwidth information and the inbound bandwidth information exceeds the preset threshold, it can be considered that the change amount of the bandwidth information exceeds the preset threshold. Among them, the outbound bandwidth information may be at least one of inbound bandwidth utilization rate, inbound error packet statistics, and inbound packet loss statistics, and the outbound bandwidth information may be at least one of outbound bandwidth utilization rate, outbound error packet statistics, and outbound packet loss statistics. For example, when the transmission function of the bandwidth utilization rate information is in the enabled state, if the change amount of the outbound bandwidth utilization rate exceeds the preset threshold or the change amount of the inbound bandwidth utilization rate exceeds the preset threshold, the simultaneous transmission of the outbound bandwidth utilization rate and the inbound bandwidth utilization rate can be triggered. When the transmission function of the error packet information is in the enabled state, if the change amount of the outbound error packet statistics exceeds the preset threshold or the change amount of the inbound error packet statistics exceeds the preset threshold, the simultaneous transmission of the outbound error packet statistics and the inbound error packet statistics can be triggered. When the transmission function of the packet loss information is in the enabled state, if the change amount of the outbound packet loss statistics exceeds the preset threshold or the change amount of the inbound packet loss statistics exceeds the preset threshold, the simultaneous transmission of the outbound packet loss statistics and the inbound packet loss statistics can be triggered. In this way, since the transmission of the two-way bandwidth information can be triggered when the change amount of the unidirectional bandwidth information exceeds the preset threshold, it is convenient for the network control system to obtain the bandwidth usage situation after the link changes in a timely manner.

[0100] The above details the transmission of bandwidth information by the first device when the transmission conditions are met. In other possible implementation manners, the first device may also transmit the bandwidth information in real time or transmit the bandwidth information at a certain period, etc., which is not specifically limited here.

[0101] In the embodiments of the present application, the bandwidth information transmitted by the network element device includes at least one of bandwidth utilization rate information, error packet information, and packet loss information. Compared with the bandwidth information transmitted by the network element device in the prior art, the bandwidth information transmitted by the network element device in the embodiments of the present application is richer, so that the usage situation of the link bandwidth can be intuitively presented, such as the congestion degree, health degree, etc. In addition, when transmitting the bandwidth information, since the message format for supporting the transmission of the bandwidth information can be extended in the transmission protocol and the bandwidth information is transmitted through the extended transmission protocol, the effective transmission of the bandwidth information can be realized. Further, since the network element device can transmit two-way bandwidth information, compared with transmitting unidirectional bandwidth information, the number of link bandwidth information flooded in the network can be reduced.

[0102] Figure 6It is a schematic flowchart of a method for transmitting bandwidth information according to an embodiment of the present application. Figure 6 The illustrated method for transmitting bandwidth information can be Figure 1 executed by the illustrated network control system. Figure 6 The illustrated method for transmitting bandwidth information is described as follows.

[0103] S602: Receive the bandwidth information transmitted by a target device in the communication network through a first transmission protocol. The bandwidth information includes at least one of bandwidth utilization information, packet error information, and packet loss information. The first transmission protocol includes a first message format, and the first message format is used to support the transmission of bandwidth information.

[0104] When the network control system manages and controls multiple network element devices in the communication network, it can receive the bandwidth information transmitted by a target device in the communication network. The target device can be any network element device in the communication network. The network element device can be randomly selected or pre-agreed upon, and no specific limitation is made here. During the process of providing network services, each network element device in the communication network can obtain the bandwidth information of the communication link with its neighbor device, and then flood the bandwidth information in the communication network. Finally, the target device in the communication network aggregates the bandwidth information of all links in the network and transmits it to the network control system. At this time, the network control system can receive the bandwidth information transmitted by the target device. Among them, for the specific implementation methods of each network element device to obtain and transmit bandwidth information, reference can be made to Figure 2 the illustrated embodiment, which will not be elaborated here.

[0105] When the network control system receives the bandwidth information transmitted by the target device, it can receive it through the first transmission protocol. The first transmission protocol includes a first message format, and the first message format is used to support the transmission of bandwidth information. Thus, the effective reception of bandwidth information can be achieved.

[0106] The bandwidth information received by the network control system can include at least one of bandwidth utilization information, packet error information, and packet loss information. Among them, the bandwidth utilization information in the bandwidth information can include at least one of inbound bandwidth utilization and outbound bandwidth utilization. The packet error information can include at least one of inbound packet error statistics and outbound packet error statistics. The packet loss information can include at least one of inbound packet loss statistics and outbound packet loss statistics. For the explanatory descriptions of each item of bandwidth information, reference can be made to Figure 2 the corresponding content in the illustrated embodiment, which will not be described in detail here.

[0107] Optionally, in some embodiments, the outbound bandwidth utilization and the inbound bandwidth utilization may be real-time bandwidth utilization. In other embodiments, the outbound bandwidth utilization and the inbound bandwidth utilization may also be the average values over a certain time period. For example, the inbound bandwidth utilization may be the average value of the inbound bandwidth utilization of the link within a first time period, and the outbound bandwidth utilization may be the average value of the outbound bandwidth utilization of the link within a second time period. Both the first time period and the second time period can be determined according to actual service requirements and are not specifically limited here. The first time period and the second time period may be the same or different.

[0108] Optionally, in some embodiments, the outbound error packet statistics at one end of the link are equal to the inbound error packet statistics at the other end of the link, and the inbound error packet statistics at one end of the link are equal to the outbound error packet statistics at the other end of the link. In other embodiments, the outbound error packet statistics at one end of the link may not be equal to the inbound error packet statistics at the other end, and / or the inbound error packet statistics at one end of the link are not equal to the outbound error packet statistics at the other end. In this case, there will be two sets of inbound error packet statistics and / or two sets of outbound error packet statistics for the link. To better reflect the error packet situation of the link, if there are two sets of inbound error packet statistics for the link, the maximum value of the two sets of inbound error packet statistics can be used as the final inbound error packet statistics of the link. Similarly, when obtaining the outbound error packet statistics of the link, if there are two sets of outbound error packet statistics for the link, the maximum value of the two sets of outbound error packet statistics can be used as the final outbound error packet statistics of the link.

[0109] Optionally, in some embodiments, the outbound packet loss statistics at one end of the link are equal to the inbound packet loss statistics at the other end of the link, and the inbound packet loss statistics at one end of the link are equal to the outbound packet loss statistics at the other end of the link. In other embodiments, the outbound packet loss statistics at one end of the link may not be equal to the inbound packet loss statistics at the other end, and / or the inbound packet loss statistics at one end of the link are not equal to the outbound packet loss statistics at the other end. In this case, there will be two sets of inbound packet loss statistics and / or two sets of outbound packet loss statistics for the link. To better reflect the packet loss situation of the link, if there are two sets of inbound packet loss statistics for the link, the maximum value of the two sets of inbound packet loss statistics can be used as the final inbound packet loss statistics of the link. Similarly, when obtaining the outbound packet loss statistics of the link, if there are two sets of outbound packet loss statistics for the link, the maximum value of the two sets of outbound packet loss statistics can be used as the final outbound packet loss statistics of the link.

[0110] The first transmission protocol can be a protocol obtained by extending an existing transmission protocol. Optionally, in some embodiments, the first transmission protocol can be a protocol obtained by adding a first message format to the ISIS protocol, or a protocol obtained by adding a first message format to the OSPF protocol, or a protocol obtained by adding a first message format to the BGP. For the specific method of adding the first message format to the ISIS protocol, OSPF protocol, and BGP protocol, reference can be made to Figure 2 the corresponding content in the illustrated embodiments, which will not be elaborated here. Among them, the first message format added to the ISIS protocol, OSPF protocol, and BGP protocol can be represented as TLV or Sub-TLV.

[0111] The first message format can have one or more formats. A message of one format can be used to support the transmission of one type of bandwidth information, and messages of different formats can be used to support the transmission of different types of bandwidth information. Optionally, in some embodiments, when the bandwidth information includes bandwidth utilization information, the first message format can include at least one of a type field, a valid value field, an exception setting field, a traffic type field, a reserved field, an inbound link bandwidth utilization field, and an outbound link bandwidth utilization field. When the bandwidth information includes packet error information, the first message format can include at least one of a type field, a valid value field, an exception setting field, a reserved field, an inbound link packet error statistics field, and an outbound link packet error statistics field. When the bandwidth information includes packet loss information, the first message format can include at least one of a type field, a valid value field, an exception setting field, a reserved field, an inbound link packet loss statistics field, and an outbound link packet loss statistics field. For the specific explanation of the first message format, reference can be made to Figure 2 the explanation of the first message format in the illustrated embodiments, which will not be described in detail here.

[0112] In the embodiments of the present application, the bandwidth information received by the network control system includes at least one of bandwidth utilization information, packet error information, and packet loss information. Compared with the bandwidth information received in the prior art, the bandwidth information received in the embodiments of the present application is richer, so that the usage situation of the link bandwidth, such as congestion degree, health degree, etc., can be intuitively presented. In addition, when receiving the bandwidth information, since the message format for supporting the transmission of the bandwidth information can be extended in the transmission protocol and the bandwidth information can be received through the extended transmission protocol, the effective reception of the bandwidth information can be achieved. Further, since the network element device can transmit two-way bandwidth information, compared with transmitting one-way bandwidth information, the number of link bandwidth information flooded in the network can be reduced.

[0113] To facilitate understanding of the technical solutions provided in the embodiments of the present application, reference can be made to Figures 7 to 9 .

[0114] Figure 7 It is a schematic diagram of the transmission of bandwidth utilization information in an embodiment of the present application. Figure 7 It includes a total of 5 router devices, namely R1, R2, R3, R4, and R5. The basic configuration IGP between devices is ISIS or OSPF, the network element devices are configured with BGP for docking with the network control system, and the inbound and outbound statistical capabilities of the ports on the network elements are enabled. The links between all devices are 10GE links, and TE reserved bandwidth is not set. Among them, the link between R1 - R2 is marked as link ①, the link between R2 - R3 is marked as link ②, the link between R2 - R4 is marked as link ③, and the link between R4 - R5 is marked as link ④. Figure 7 There are a total of 4 traffic flows in the shown network, namely a 1G traffic flow from R1 to R5, a 2G traffic flow from R4 to R1, a 3G traffic flow from R1 to R3, and a 4G traffic flow from R3 to R5. The specific traffic flow directions are as Figure 7 shown.

[0115] Figure 7 When the shown network transmits bandwidth utilization information, the following steps may be included:

[0116] Step 1: Bandwidth utilization notification is not enabled.

[0117] On the interface where R1 is docked with R2, the outbound traffic is counted as 4G. At this time, R1 notifies that the unidirectional remaining bandwidth of link ① is 10G, the unidirectional available bandwidth is 6G, the unidirectional used bandwidth is 4G, and the bandwidth utilization rate is calculated externally as 40%. On the interface where R2 is docked with R1, the outbound traffic is counted as 2G. At this time, R2 notifies that the unidirectional remaining bandwidth of link ① is 10G, the unidirectional available bandwidth is 8G, the unidirectional used bandwidth is 2G, and the bandwidth utilization rate is calculated externally as 20%. In summary, the network control system can view that the two-way bandwidth utilization rates of link ① are 20% and 40% respectively;

[0118] Step 2: Bandwidth utilization notification is enabled.

[0119] On the interface of R1, the outbound bandwidth utilization rate is counted as 40%, and the inbound bandwidth utilization rate is 20%. R1 directly notifies that the two-way bandwidth utilization rates of link ① are 20% and 40% respectively.

[0120] Step 3: Bandwidth utilization notification is enabled.

[0121] Similarly, on R2, R3, and R4, the interface bandwidth utilization rates are respectively counted, and in the network, the two-way bandwidth utilization rates of link ② are notified as 30% and 40% respectively, the two-way bandwidth utilization rates of link ③ are notified as 20% and 50% respectively, and the two-way bandwidth utilization rates of link ④ are notified as 0% and 50% respectively.

[0122] Figure 8It is a schematic diagram of the transmission of bandwidth utilization information in an embodiment of the present application. Figure 8 It includes a total of 5 router devices, namely R1, R2, R3, R4, and R5. The basic configuration IGP between devices is ISIS or OSPF, the network element devices are configured with BGP for docking with the network control system, and the inbound and outbound statistical capabilities of the ports on the network elements are enabled. The links between all devices are 10GE links, and TE reserved bandwidth is set. Among them, 2G bandwidth is reserved for the path from R1 to R5, and 3G bandwidth is reserved for the path from R4 to R1. The link from R1 to R2 is marked as link ①, the link from R2 to R3 is marked as link ②, the link from R2 to R4 is marked as link ③, and the link from R4 to R5 is marked as link ④. Figure 8 There are a total of 4 traffic flows in the shown network, namely a 1G traffic flow in the tunnel from R1 to R5, a 2G traffic flow in the tunnel from R4 to R1, a 3G traffic flow from R1 to R3, and a 4G traffic flow from R3 to R5. The specific traffic flow directions are as Figure 8 shown.

[0123] Figure 8 When the shown network transmits bandwidth utilization information, the following steps may be included:

[0124] Step 1: Bandwidth utilization notification is not enabled.

[0125] On the interface where R1 is docked with R2, the outbound traffic is counted as 4G. At this time, R1 notifies that the unidirectional remaining bandwidth of link ① is 8G, the unidirectional available bandwidth is 4G, the unidirectional used bandwidth is 4G, and the bandwidth utilization rate of the link is 40%. On the interface where R2 is docked with R1, the outbound traffic is counted as 2G. At this time, R2 notifies that the unidirectional remaining bandwidth of link ① is 7G, the unidirectional available bandwidth is 5G, the unidirectional used bandwidth is 2G, and the bandwidth utilization rate of the link is 20%. Due to the existence of TE reserved bandwidth, the calculated value of the used bandwidth / remaining bandwidth of the link at this time is not equal to the bandwidth utilization rate of the link.

[0126] Step 2: Bandwidth utilization notification is enabled.

[0127] On the interface of R1, the outbound bandwidth utilization rate is counted as 40%, and the inbound bandwidth utilization rate is 20%. R1 directly notifies that the bidirectional bandwidth utilization rates of link ① are 20% and 40% respectively.

[0128] Step 3: Bandwidth utilization notification is enabled.

[0129] Similarly, the interface bandwidth utilization rates are respectively counted on R2, R3, and R4, and the bidirectional bandwidth utilization rates of link ② are notified as 30% and 40% respectively in the network, the bidirectional bandwidth utilization rates of link ③ are 20% and 50% respectively, and the bidirectional bandwidth utilization rates of link ④ are 0% and 50% respectively.

[0130] Figure 9 It is a schematic diagram of the transmission of mispacket information in an embodiment of the present application. Figure 9 In the figure, devices R1 and R2 are directly connected, and the inbound and outbound mispacket statistics of the ports are enabled. Among them, there are 50 mispackets per second in the packets sent by R1, and 100 mispackets per second in the received packets. The current outbound mispacket statistics on the R1 side are 1000, and the inbound mispacket statistics are 1500. There are 100 mispackets per second in the packets sent by R2, and 50 mispackets per second in the received packets. The current outbound mispacket statistics on the R2 side are 2500, and the inbound mispacket statistics are 500.

[0131] Figure 9 When the network shown in the figure transmits mispacket information, the following steps may be included:

[0132] Step 1: Enable the notification of the inbound and outbound mispacket counts of R1, set the notification update threshold to 10%, and the currently notified inbound mispacket count is 1500, and the outbound mispacket count is 1000.

[0133] Step 2: After 1.5 s, the inbound mispackets increase by 150, and the outbound mispackets increase by 75. Among them, the increase in the inbound mispacket count exceeds 10%, and at this time, the protocol is updated, and the notification information is that the inbound mispacket count is 1650, and the outbound mispacket count is 1075.

[0134] Step 3: Enable the notification of the inbound and outbound mispacket counts of R2, set the notification update threshold to 20%, and the currently notified inbound mispacket count is 500, and the outbound mispacket count is 2500.

[0135] Step 4: After 2 s, the inbound mispackets increase by 100, and the outbound mispackets increase by 200. Among them, the increase in the inbound mispacket count exceeds 20%, and at this time, the protocol is updated, and the notification information is that the inbound mispacket count is 600, and the outbound mispacket count is 2700.

[0136] It can be seen that the embodiment of the present application proposes an extended design of a basic routing protocol, which can be used to transmit information such as the bandwidth utilization rate of the link. By defining new types of TLVs or Sub-TLVs in ISIS / OSPF / BGP, information related to the link bandwidth such as the inbound bandwidth utilization rate, the outbound bandwidth utilization rate, the inbound mispacket statistics, the outbound mispacket statistics, the inbound packet loss statistics, and the outbound packet loss statistics can be carried. It supports the manager to intuitively evaluate the congestion degree, health degree and other states of the link in the network control system. By simultaneously notifying the inbound and outbound bandwidth information by network element devices, the number of flooded link bandwidth information in the network is also reduced.
