Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular, to a bandwidth control method, apparatus, device, and computer-readable storage medium. Background Art

[0002] Microwave products have PLA and Multiband functions. The PLA function aggregates multiple microwave physical links into a virtual microwave link. Each microwave physical link transmits sliced packets of the PLA virtual link's packets, and after sending them to the opposite end, the sliced packets of each physical link are restored to the original packets at the PLA virtual interface. The Multiband function, based on the priority of the packets on the basis of PLA, selectively transmits the sliced packets on the normal band or extended band of the member links. Each microwave communication device that makes up the link needs to be able to interact the current available bandwidth of each microwave communication device itself in order to correctly select the packets to the appropriate link for sending. Microwave communication devices of the same manufacturer usually use an internal private protocol for communication to complete the interaction of bandwidth information. However, since devices of different manufacturers cannot interact bandwidth with each other, when sending service packets through the service sending link composed of these microwave communication devices, the bandwidth of this service sending link can only be fixedly set to the minimum bandwidth supported by these microwave communication devices together; and the available bandwidth of microwave communication devices may change according to the change of their debugging methods, and the transmission bandwidth will also change accordingly. Therefore, currently using microwave communication devices to form a network in a fixed minimum bandwidth manner may waste bandwidth resources to a great extent. Summary of the Invention

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the embodiments of the present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] Embodiment 1:

[0031] Regarding the problem in the related art that due to the inability to obtain the bandwidth change situation of the microwave communication device, the microwave communication device is used for networking in a fixed minimum bandwidth manner, resulting in waste of bandwidth resources; in this embodiment, a standard protocol connection is established between the managed microwave communication device and the managed microwave communication device on the service sending link, and the bandwidth change notification of the managed microwave communication device is exchanged through this standard protocol connection. Furthermore, the managed microwave communication device can dynamically update the bandwidth of the service sending link according to the obtained bandwidth change information, rather than being fixedly set to the minimum bandwidth supported by each managed microwave communication device. Therefore, the bandwidth resources can be utilized more reasonably, and the bandwidth resource utilization rate can be improved. For the convenience of understanding, this embodiment will be described below in conjunction with Figure 1 the bandwidth control method shown in Figure 1 shown, the bandwidth control method includes:

[0032] S101: Obtain the bandwidth change notification sent by the managed microwave communication device through the standard protocol connection established with the managed microwave communication device on the service sending link.

[0033] The standard protocol connection in this embodiment is established between the managed microwave communication device and the to-be-managed microwave communication device on the service sending link, and is used to transmit the bandwidth change notification sent by the to-be-managed microwave communication device. It should be understood that the standard protocol connection can be any standard protocol connection that can achieve the above purpose; for example, the standard protocol connection can include, but is not limited to, any one of the Ethernet operation, administration, and maintenance (Operation Administration and Maintenance, OAM) connection and the Resource Reservation Protocol (RSVP) connection. Moreover, the use of the standard protocol connection has good versatility and applicability, small changes, easy implementation, low cost, and is not restricted by different device manufacturers. Of course, in some application scenarios, a non-standard protocol connection can also be used.

[0034] In this embodiment, the bandwidth change notification sent by the to-be-managed microwave communication device includes the bandwidth change information of the to-be-managed microwave communication device, and it should be understood that the bandwidth change information can include at least one of the available bandwidth value after the current change of the to-be-managed microwave communication device, the specific bandwidth variable, and the bandwidth change trend (such as increasing or decreasing). It can be specifically set flexibly according to the application scenario requirements.

[0035] In this embodiment, the to-be-managed microwave communication device can include, but is not limited to, third-party microwave communication devices; the third-party microwave communication devices in this embodiment include various devices that cannot complete bandwidth information interaction with the managed microwave communication device through a private protocol. For example, it can include, but is not limited to, at least one of the microwave communication devices belonging to different device manufacturers from the managed microwave communication device, and the microwave communication devices belonging to the same manufacturer as the managed microwave communication device but unable to complete bandwidth information interaction with the managed microwave communication device through a private protocol due to different firmware versions or other reasons.

[0036] It should be understood that S101 can be executed by, but is not limited to, the managed microwave communication device, or can also be executed by other management devices.

[0037] The service sending link in this embodiment is for the managed microwave communication device. The managed microwave communication device may have only one service sending link, or may have multiple service sending links. In the service sending links of the managed microwave communication device, it is possible that the to-be-managed microwave communication devices exist on all the service sending links, or only some of the service sending links, or none of the service sending links. It can be specifically arranged flexibly according to the requirements.

[0038] For ease of understanding, the following uses a Multiband networking structure as an example for illustration. Please refer to Figure 2 as shown. In Figure 2 , the microwave communication device in the extended band Eband is an extended band device, and the microwave communication device in the normal band Normalband is a normal band device. In Figure 2 , for the extended band device A, one of its service transmission chains consists of the extended band device A, the normal band device C, the normal band device D, and the extended band device B, and the transmission direction is from the extended band device A to the extended band device B. On this service transmission link, when the normal band devices C and D are third-party microwave communication devices, the extended band device B can be used as a managed microwave communication device, and the normal band devices C and D can be used as managed microwave communication devices. For the normal band device C, one of its service transmission chains consists of the normal band device C and the extended band device A. When the extended band device A is a third-party microwave communication device, the normal band device C can also be used as a managed microwave communication device, and the extended band device A can be used as a managed microwave communication device.

[0039] According to the above example, it can be seen that in this embodiment, the managed microwave communication device can be an extended band device in some application scenarios and a normal band device in other application scenarios. That is, the managed microwave communication device can be an extended band device or a normal band device.

[0040] According to the above example, it can be seen that in this embodiment, the service transmission link can include only one managed microwave communication device, and the managed microwave communication device and the managed microwave communication device on this service transmission link are connected byte by a standard protocol. The service transmission link can also include only two or more managed microwave communication devices, and the managed microwave communication devices can be connected in sequence. The managed microwave communication device that is the previous one of the managed microwave communication devices is connected to the managed microwave communication device through the above standard protocol. And it should be understood that the connection between the managed microwave communication devices can be a standard protocol connection or a non-standard protocol connection, as long as it can implement the transparent transmission of bandwidth change notifications and transmit them to the managed microwave communication device.

[0041] S102: According to the obtained bandwidth change information, determine the minimum available bandwidth among the current available bandwidths of each managed microwave communication device on this service transmission link as the target available bandwidth.

[0042] It should be understood that what is determined here is the minimum available bandwidth among the currently available bandwidths of each managed microwave communication device on the service sending link, rather than the minimum bandwidth fixedly supported by each managed microwave communication device. For example, assume that there are managed microwave communication device 1, managed microwave communication device 2, and managed microwave communication device 3 successively connected to the managed microwave communication device on the service sending link; the service bandwidths supported by these three managed microwave communication devices all include 370M, 400M, 440M, 450M, 480M, 510M, and 560M. In the related art, in order to ensure the availability of the service link, the bandwidth of the service link is directly fixedly set to be less than or equal to the minimum bandwidth of 370M supported by all three managed microwave communication devices. In S102 of this embodiment, assume that the bandwidth corresponding to the modulation method currently adopted by managed microwave communication device 1 is 450M, the bandwidth corresponding to the modulation method currently adopted by managed microwave communication device 2 is 510M, and the bandwidth corresponding to the modulation method currently adopted by managed microwave communication device 2 is 560M. Then, among the currently available bandwidths (450M, 510M, and 560M respectively) of each managed microwave communication device on this service sending link, the minimum available bandwidth is 450M. Furthermore, the current bandwidth of the service sending link can be reasonably set according to this minimum available bandwidth of 450M, so as to make more full use of the bandwidth resources.

[0043] S103: Set the current bandwidth of the service sending link according to the target available bandwidth.

[0044] In an application scenario, since the managed microwave communication device, as the managed party, needs to reserve network management bandwidth resources (for establishing a management link) to transmit management messages. Therefore, setting the current bandwidth of the service sending link according to the target available bandwidth may include:

[0045] Subtract the bandwidth required by the management link of the managed microwave communication device from the target available bandwidth, and use the obtained remaining bandwidth as the current bandwidth of the service sending link. For example, continuing the above example, assume that the determined target available bandwidth is 450M, and the bandwidth required by the management link is 2M (this value can be flexibly set according to the specific application scenario). Then, set the current bandwidth of the service sending link to 448M. Therefore, compared with the method of fixedly setting to be less than or equal to 370M in the related art, the resource utilization rate can be greatly improved. Of course, in some application scenarios, when there is no need to reserve network management bandwidth resources for the managed microwave communication device, the target available bandwidth can be directly set as the current bandwidth of the service sending link.

[0046] It can be seen that:

[0047] 1) Through the bandwidth control method provided in this embodiment, when dealing with microwave PLA and Multiband networking, if a microwave communication device that cannot complete bandwidth information interaction through a private protocol of other manufacturers or this manufacturer is entrusted, in the Multiband networking application scenario, a microwave device of a third-party manufacturer can act as a device in the Multiband frequency band or the Eband frequency band; and the entrusted microwave communication device can perceive the bandwidth change of the entrusted microwave communication device through the above method, so as to more accurately adjust the traffic of the physical channel sent to the entrusted microwave communication device, thus not having to fix the bandwidth sent to the entrusted microwave communication device to the minimum value, greatly increasing the bandwidth utilization rate of the entrusted microwave communication device;

[0048] 2) This embodiment can also use existing or subsequently specified Ethernet standard protocols for connection, which is not restricted by different manufacturers, is easy to implement and has good versatility, and the entrusted microwave communication device does not need to perceive the working principle of the trustee microwave communication device, and only needs to execute according to the Ethernet protocol standard;

[0049] 3) It has flexible deployment and is not restricted by the number of network elements of the entrusted microwave communication device;

[0050] 4) The supported Ethernet standard protocol connections can be flexible and variable, and can adapt to various Ethernet standard protocol connections with different characteristics;

[0051] 5) The bandwidth calculation is accurate, and basically the current available bandwidth of the entrusted microwave communication device can be fully utilized dynamically.

[0052] Embodiment 2:

[0053] For the convenience of understanding, on the basis of the above embodiment, this embodiment takes the standard protocol connection established between the trustee microwave communication device and the entrusted microwave communication device on the service sending link as an OAM connection as an example for illustration.

[0054] In this embodiment, the entrusted microwave communication device is configured as a server maintenance endpoint Server MEP; the trustee microwave communication device is configured as a client maintenance endpoint Client MEP. At this time, obtaining the bandwidth change notification sent by the entrusted microwave communication device includes:

[0055] Receive the operation and maintenance management message sent by the entrusted microwave communication device through the Ethernet operation and maintenance management connection between the trustee microwave communication device and the entrusted microwave communication device. The operation and maintenance management message carries the bandwidth change notification;

[0056] In this embodiment, it is set that the level of the Maintenance Domain (MD) in the operation and maintenance management message is greater than the level of the maintenance domain of the managed microwave communication device and equal to the level of the maintenance domain of the hosting microwave communication device. In this way, when there are multiple managed microwave communication devices on the service sending link, it is ensured that the operation and maintenance management messages sent by the managed microwave communication devices are transparently transmitted among the managed microwave communication devices and thus transmitted to the hosting microwave communication device, and it is ensured that the hosting microwave communication device has the authority to parse and process the operation and maintenance management message. The specific type of the operation and maintenance management message in this embodiment can also be flexibly set according to the specific application scenario. For example, in one application scenario, the operation and maintenance management message includes, but is not limited to, a Connectivity Fault Management (CFM) message.

[0057] In one application scenario of this embodiment, the bandwidth change information included in the bandwidth change notification carried in the operation and maintenance management message may include the current available bandwidth of the managed microwave communication device; of course, according to needs, it can also be set that the bandwidth change notification includes the maximum bandwidth supported by the managed microwave communication device.

[0058] In this embodiment, according to the obtained bandwidth change information, determining the minimum available bandwidth among the current available bandwidths of each managed microwave communication device on the service sending link as the target available bandwidth includes:

[0059] After updating the available bandwidth of the managed microwave communication device that sends the operation and maintenance management message (for example, assumed to be 370M) to the available bandwidth in the operation and maintenance management message (for example, assumed to be 510M), obtain the minimum available bandwidth among the current available bandwidths of each managed microwave communication device on the service sending link as the target available bandwidth.

[0060] For the convenience of understanding, the following of this embodiment takes Figure 3 and Figure 4 two Multiband networking application scenarios shown as examples for illustration. However, it should be understood that the solution provided in this embodiment is not limited to Multiband networking applications, and is also applicable to PLA networking and other arbitrary scenarios that need to obtain the bandwidth change situation of the managed microwave communication device.

[0061] In this example, the managed microwave communication device may specifically adopt, but is not limited to, the Eth-BN (Ethernet bandwidth notification) Ethernet bandwidth notification function in Ethernet OAM G.8013 / Y.1731.

[0062] In this application scenario, a managed microwave communication device manages other microwave communication devices from different manufacturers as the managed microwave communication devices. For example, please refer to Figure 3 (single-hop networking) and Figure 4 (multi-hop networking) as shown by the extended-band device A. Assume it is a managed microwave communication device, Figure 3 and the conventional microwave communication device C in it is the managed microwave communication device. Figure 4 The conventional microwave communication devices C, D, and E in it are the managed microwave communication devices. Of course, in some examples, the managed microwave communication device can also be an extended-band device, and the managed microwave communication device is a conventional-band device. For example Figure 3 the extended-band device B in it can be the managed microwave communication device, and the conventional microwave communication device D can be the managed microwave communication device.

[0063] Configure the managed microwave communication device as Server MEP, configure ClientMEP on the unmanaged microwave communication device, and set the MD level of the managed microwave communication device to be higher than the MD level of the managed microwave communication device to receive the OAM packets (such as CFM packets) sent by the managed microwave communication device. The MD level in the packets sent by the managed microwave communication device is configured as the MD priority of the managed microwave communication device, so as to achieve transparent transmission between the managed microwave communication devices. For example, in Figure 4 the BN packet sent by the managed microwave communication device E is transparently transmitted to the managed microwave communication device A through the managed microwave communication devices C and D in sequence.

[0064] In this embodiment, for the scenario of multi-hop networking (such as Figure 4 shown), a first virtual local area network (VLAN) can be established on the managed microwave communication device to transmit Ethernet OAM packets, and a second VLAN can be established to transmit service slice packets. The physical network interface on the managed microwave communication device connected to the managed microwave communication device can be set to two virtual interfaces, one for transmitting service slice packets. The other is used to establish Ethernet OAM with the managed microwave communication device. Optionally, the logical interface and VLAN for transmitting OAM packets on the managed microwave communication device can be multiplexed with the network management VLAN of the managed microwave communication device.

[0065] When the modulation mode of the managed microwave communication device changes, for example, when the bandwidth becomes smaller or larger, an OAM message (such as a CFM message) will be sent to the managing microwave communication device. The OAM message may include the current available bandwidth and the maximum supported bandwidth of the managed microwave communication device. After receiving the PAM message, the managing microwave communication device dynamically adjusts the traffic of the sliced message sent to the managed microwave communication device according to the notified bandwidth and the bandwidth reserved for the network management channel of the managed microwave communication device, that is, dynamically adjusts the bandwidth of the service sending link where the managed microwave communication device is located.

[0066] The bandwidth control method in this embodiment is not limited by the number of hops of the transmission link of the managed microwave communication device. Since the CFM message can pass through the MEP with a lower priority than the Client MEP, the BNM messages monitored on each link of the managed microwave communication device can be transmitted to the managing microwave communication device. When calculating the link bandwidth of the managed microwave communication device, the managing microwave communication device takes the minimum value of the bandwidth on the link and also considers the consumption of the network management bandwidth guarantee of the managed microwave communication device, so as to accurately adjust the traffic of the sliced message sent to the managed microwave communication device.

[0067] Embodiment 3:

[0068] For the sake of easy understanding, on the basis of the above embodiment, this embodiment takes the standard protocol connection established between the managing microwave communication device and the managed microwave communication device on the service sending link as an RSVP protocol connection as an example for description.

[0069] In this embodiment, obtaining the bandwidth change notification sent by the managed microwave communication device includes:

[0070] Receiving the bandwidth change notification sent by the managed microwave communication device through the resource reservation protocol connection between the managing microwave communication device and the managed microwave communication device; and the detection tunnel spans each managed microwave communication device on the service sending link.

[0071] In this embodiment, the detection tunnel includes a basic detection tunnel and an incremental detection tunnel; where the bandwidth of the basic detection tunnel is the minimum bandwidth corresponding to various modulation modes adopted by each managed microwave communication device on the service sending link, and the bandwidth of the incremental detection tunnel is the difference between the bandwidths corresponding to two adjacent modulation modes in sequence.

[0072] For example, in an application scenario, when each managed microwave communication device on the service sending link has a physical bandwidth of 56M, the transmission bandwidth values under modulation modes of 256QAM, 512QAM, 1024QAM, 1024QAM_L, 2048QAM, 4096QAM, and 8192QAM are 370M, 400M, 440M, 450M, 480M, 510M, and 560M respectively. Then, the detection tunnels to be established include a basic detection tunnel with a specified bandwidth (bandwidth is 370M) of 370M, and 6 successively adjacent increasing detection tunnels with bandwidths of 30M, 40M, 10M, 30M, 30M, and 50M respectively. For details, please refer to Figure 5 as shown. When the transmission bandwidth is the maximum bandwidth, all these detection tunnels can be successfully established, and the obtained bandwidth is the sum of the bandwidths of all tunnels, which is 560M.

[0073] In this embodiment, according to the bandwidth change information, determining the minimum available bandwidth among the current available bandwidths of each managed microwave communication device on the service sending link as the target available bandwidth includes:

[0074] When the bandwidth change notification includes deletion detection tunnel indication information, after deleting the corresponding increasing detection tunnel from the currently established increasing detection tunnels according to the detection tunnel indication information, the sum of the bandwidths of the remaining detection tunnels is used as the minimum available bandwidth. For example, assume that the currently established detection tunnels include a basic detection tunnel (370M) and increasing detection tunnels (30M), increasing detection tunnels (40M), and increasing detection tunnels (10M); the deletion detection tunnel indication information included in the bandwidth change notification indicates the deletion of the increasing detection tunnel (10M). Then, the increasing detection tunnel (10M) is deleted, and the sum of the bandwidths of the remaining detection tunnels is 370M + 30M + 40M = 440M.

[0075] When the bandwidth change notification includes bandwidth increase indication information, based on this bandwidth increase indication information, on the basis of the currently established detection tunnels, the corresponding increasing detection tunnels are successively selected to be established with each managed microwave communication device on the service sending link until the establishment of the currently selected increasing detection tunnel fails; then, the sum of the bandwidths of all the currently established detection tunnels is used as the minimum available bandwidth.

[0076] For example, assume that the currently established detection tunnels include a basic detection tunnel (370M), an incremental detection tunnel (30M), an incremental detection tunnel (40M), and an incremental detection tunnel (10M); when the bandwidth increase indication information is included in the bandwidth change notification, the incremental detection tunnel (30M) is attempted to be established in sequence. After successful establishment, the next incremental detection tunnel (30M) is attempted to be established. If it is successfully created again, the incremental detection tunnel (50M) is attempted to be created. If all are successfully created, the target bandwidth obtained at this time is the sum of the bandwidths of all tunnels, which is 560M.

[0077] In an application scenario of this embodiment, the function of the created detection tunnel can be only used to sense the transmission bandwidth of the managed microwave communication device; it is not used for transmitting services. Route isolation can be configured on the managed microwave communication device to ensure that service data will not be transmitted to the detection tunnel TE TUNNEL of the detection bandwidth. In this embodiment, service packets can also be transmitted in the form of slices in a VLAN of the managed microwave communication device.

[0078] For ease of understanding, this embodiment will be described below in conjunction with Figure 6 and Figure 7 The networking application scenario shown is used as an example for illustration. Please refer to Figure 6 and Figure 7 As shown, the extended band device A is used as the managed microwave communication device, and the conventional band device on the service sending link of the conventional band of the extended band device A is used as the entrusted microwave communication device. Among them, when the debugging method of the managed microwave communication device changes, such as when the bandwidth increases; the tunnel with the difference in modulation method bandwidth from the previous level (for example, Figure 6 and Figure 7 the incremental detection tunnel with a bandwidth of 40M in the bandwidth) will be established first. After successful establishment, the data traffic sent to the managed microwave communication device is adjusted to the new bandwidth value; and the channel for the next incremental detection tunnel is attempted to be established until the establishment of the next incremental detection tunnel fails or all incremental detection tunnels are established.

[0079] When the transmission bandwidth of the managed microwave communication device becomes smaller, some of the incremental detection tunnels of the established detection tunnels are disconnected. The managed microwave communication device immediately adjusts the bandwidth sent to the managed microwave communication device to the sum of the bandwidths of the currently remaining unbroken tunnels; and deletes the disconnected incremental detection tunnels.

[0080] The actual tunnel adjustment method is not limited to the above one. They will not be listed one by one.

[0081] The method exemplified in this embodiment is not limited by the transmission hop count of the managed microwave communication device either. Since the specified bandwidth of the detection tunnel needs to be satisfied by each bandwidth on the transmission link to be successfully established. Therefore, the bandwidth monitored by the detection tunnel is the minimum value of each section of the microwave link on this link.

[0082] Example 4:

[0083] This embodiment also provides a bandwidth control device, which can be set in a microwave communication device (such as a base station). Please refer to Figure 8 as shown, including:

[0084] An information acquisition module 801, configured to obtain a bandwidth change notification sent by a managed microwave communication device through a standard protocol connection established with the managed microwave communication device on the service sending link. The bandwidth change notification includes the bandwidth change information of the managed microwave communication device, and the managed microwave communication device includes a third-party microwave communication device; for the specific acquisition and parsing process, please refer to the above embodiments, which will not be elaborated here.

[0085] A bandwidth control module 802, configured to determine, according to the bandwidth change information obtained by the information acquisition module 801, the minimum available bandwidth among the current available bandwidths of each managed microwave communication device on the service sending link as the target available bandwidth, and set the current bandwidth of the service sending link according to the target available bandwidth. For the specific control process, please refer to the above embodiments, which will not be elaborated here either.

[0086] The bandwidth control device provided in this embodiment can enable the managed microwave communication device to perceive the bandwidth change of the managed microwave communication device through the above method, so as to more accurately adjust the traffic of the physical channel sent to the managed microwave communication device, so that the bandwidth sent to the managed microwave communication device does not need to be fixed at the minimum value, greatly increasing the bandwidth utilization rate of the managed microwave communication device; and the bandwidth control device can also use the existing or subsequent specified Ethernet standard protocol connection, which is not restricted by different manufacturers, is easy to implement and has good versatility, and the managed microwave communication device does not need to perceive the working principle of the managed microwave communication device, and only needs to execute according to the Ethernet protocol standard.

[0088] This embodiment also provides a microwave communication device, which can be used as a managed microwave communication device. Please refer to Figure 9 as shown, which includes a processor 901, a memory 902, and a communication bus 903;

[0089] The communication bus 903 is used to implement the communication connection between the processor 901 and the memory 902;

[0090] In an example, the processor 901 can be used to execute one or more computer programs stored in the memory 902 to implement the steps of the bandwidth control method in the above embodiments.
