Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method and apparatus for determining transmitted information. Background Technology

[0002] In existing technologies, at the IP layer, the Open Shortest Path First (OSPF) protocol typically uses a manually negotiated default Maximum Transmission Unit (MTU) value. For example, some router networks negotiate an MTU value of 4600 or 1500 to achieve OSPF interoperability between network devices. However, IP layer packet fragmentation and reassembly are mainly limited by the data link layer or interface. The IP layer MTU value can only be better negotiated after determining the MTU value of the data link layer or interface. However, there is currently no clear solution for negotiating and determining the MTU value of the data link layer or interface. Summary of the Invention

[0003] The purpose of this invention is to provide a method and apparatus for determining transmitted information, so as to solve the problem of how to negotiate and determine the MUT value of the data link layer or interface.

[0004] To achieve the above objectives, embodiments of the present invention provide a data processing method, comprising:

The second MTU negotiation information includes the second MTU negotiation strategy indicated by the second network element management unit according to the priority of the first MTU negotiation strategy.

[0007] The first network element management unit determines the target MTU value of the first interface of the first network element according to the second MTU negotiation strategy. The target MTU value is the MTU value when data is transmitted between the first network element and the second network element, and the second network element is the neighboring network element of the first network element.

[0008] Optionally, the priority of the second MTU negotiation strategy is higher than the priority of the first MTU negotiation strategy, or the priority of the second MTU negotiation strategy is the same as the priority of the first MTU negotiation strategy.

[0019] When the second MTU negotiation strategy is an intermediate capability MTU value negotiation strategy, the MTU configuration value of the first interface and the MTU configuration value of the second interface are compared to obtain the larger MTU configuration value and the smaller MTU configuration value.

[0020] The larger MTU configuration value is compared with the MTU capability value corresponding to the smaller MTU configuration value, and the smaller comparison value is obtained;

[0023] When the second MTU negotiation strategy is the maximum capacity MTU value negotiation strategy, the MTU capacity value of the first interface and the MTU capacity value of the second interface are compared to obtain the smaller MTU capacity value.

[0042] The larger MTU configuration value is compared with the MTU capability value corresponding to the smaller MTU configuration value, and the smaller comparison value is obtained;

[0072] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0073] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0074] In various embodiments of the present invention, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0075] In addition, the terms "system" and "network" are often used interchangeably in this article.

[0076] In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0077] like Figure 1 As shown, this embodiment of the invention provides a method for determining transmitted information, including:

[0078] Step 101: The first network element management unit sends the first maximum transmission unit (MTU) negotiation information to the second network element management unit. The first MTU negotiation information includes a first MTU negotiation strategy for determining the MTU value of the network element interface.

[0079] In this embodiment of the invention, the first network element management unit can be a device module or integrated into a unified management and control system. The second network element is a neighboring network element of the first network element.

[0080] Optionally, the first MTU negotiation information further includes:

[0081] The MTU configuration value for the first interface;

[0082] MTU capability value of the first interface.

[0083] The MTU capability value of the aforementioned interface is greater than the MTU configuration value of the first interface. The aforementioned first interface is the interface of the first network element.

[0084] Step 102: The first network element management unit obtains the second MTU negotiation information sent by the second network element management unit. The second MTU negotiation information includes the second MTU negotiation strategy indicated by the second network element management unit according to the priority of the first MTU negotiation strategy.

[0085] Optionally, the priority of the second MTU negotiation strategy is higher than the priority of the first MTU negotiation strategy, or the priority of the second MTU negotiation strategy is the same as the priority of the first MTU negotiation strategy.

[0086] When the priority of the second MTU negotiation strategy is the same as the priority of the first MTU negotiation strategy, the second MTU negotiation strategy can be the first MTU negotiation strategy.

[0087] Optionally, the second MTU negotiation information further includes:

[0088] MTU configuration value for the second interface;

[0089] MTU capability value of the second interface.

[0090] The MUT capability value of the second interface is greater than the MUT configuration value of the second interface. This second MTU negotiation strategy is the MUT negotiation strategy preferred by the second network element management unit. The aforementioned second interface is the interface of the second network element.

[0091] The first MTU negotiation strategy or the second MUT negotiation strategy in the embodiments of the present invention may include one of the following:

[0092] Minimum MUT value negotiation strategy;

[0093] Intermediate capability MTU value negotiation strategy;

[0094] Maximum capacity (MTU) negotiation strategy.

[0095] In this embodiment of the invention, the MTU capability value can be the maximum MTU capability supported by the device or calculated based on the maximum MTU capability supported by the device.

[0096] The three strategies mentioned above have a priority order. When the negotiation strategies of the first network element management unit and the second network element management unit are inconsistent, the strategy with higher priority is adopted. For example, the minimum MUT value negotiation strategy has the highest priority, the intermediate capacity MTU value negotiation strategy has the middle priority, and the maximum capacity MTU value negotiation strategy has the lowest priority.

[0097] For example, when the first network element management unit issues a negotiation strategy using the intermediate capability MTU value, and the second network element management unit agrees to use this strategy, it issues the intermediate capability MTU value negotiation strategy, as well as the MTU configuration value and MTU capability value of the second interface.

[0098] When the first network element management unit issues a negotiation strategy using an intermediate capability MTU value, and the second network element management unit disagrees with uniformly adopting this strategy, it issues a higher-priority minimum MTU value negotiation strategy, along with the MTU configuration value and capability value of the second interface. The first network element management unit compares and negotiates the received strategies to determine the target MTU value.

[0099] Furthermore, the minimum MTU value negotiation strategy refers to selecting the smaller configuration value between the MTU configuration value of the first interface and the MTU configuration value of the second interface as the negotiated MTU value.

[0100] The maximum capacity MTU negotiation strategy refers to selecting the smaller capacity value between the MTU capacity value of the first interface and the MTU capacity value of the second interface as the negotiated MTU value.

[0101] The intermediate capability MTU value negotiation strategy refers to selecting the smaller value as the negotiated MTU value between the larger MTU configuration value and the smaller MTU configuration value.

[0102] Step 103: The first network element management unit determines the target MTU value of the first interface of the first network element according to the second MTU negotiation strategy. The target MTU value is the MTU value when data is transmitted between the first network element and the second network element, and the second network element is the neighboring network element of the first network element.

[0103] In this embodiment of the invention, the first network element management unit sends first MTU negotiation information containing a first MUT negotiation strategy to the second network element management unit, obtains the second MTU negotiation strategy indicated by the priority of the first MTU negotiation strategy from the second network element management unit, and determines the target MTU value of the first receiving or the second interface based on the second MTU negotiation strategy. In this way, the purpose of determining the target MTU value of the interface based on the MTU negotiation strategy negotiated by the two is achieved.

[0104] Optionally, the first network element management unit determines the target MTU value of the first interface of the first network element according to the second MTU negotiation strategy, including:

[0105] According to the second MTU negotiation strategy, at least two of the MTU configuration value of the first interface, the MTU capability value of the first interface, the MTU configuration value of the second interface, and the MTU capability value of the second interface are compared to obtain the target MTU value of the first interface.

[0106] Here, the MTU configuration value, MTU capability value, MTU configuration value, and MTU capability value of the first interface are processed according to the second MTU negotiation strategy to obtain the target MTU value, so that the target MTU value can guarantee the transmission efficiency between the first network element and the second network element or reduce the transmission delay between the first network element and the second network element.

[0107] As a first optional implementation, the step of comparing at least two of the MTU configuration value of the first interface, the MTU capability value of the first interface, the MTU configuration value of the second interface, and the MTU capability value of the second interface according to the second MTU negotiation strategy to obtain the target MTU value of the first interface includes:

[0108] When the second MTU negotiation strategy is the minimum MUT value negotiation strategy, the MTU configuration value of the first interface and the MTU configuration value of the second interface are compared, and the smaller MTU configuration value is taken as the target MTU value of the first interface.

[0109] As shown in Table 1, MTU1 represents the MTU configuration value of the first interface, MTU1' represents the MTU capability value of the first interface, MTU2 represents the MTU configuration value of the second interface, and MTU2' represents the MTU capability value of the second interface. When using the minimum MTU value negotiation strategy, MTU1 and MTU2 are compared. If MTU1 is greater than MTU2, the target MTU value of the first interface is modified to MTU2. If MTU1 is less than or equal to MTU2, the target MTU value of the first interface remains MTU1. In Table 1, if MTU1 is greater than MTU2, the target MTU value of the first interface is modified to 1500.

[0110] Table 1

[0111] Strategy MTU1 MTU1' MTU2 MTU2' Minimum Value Negotiation Strategy 4600 9600 1500 6000

[0112] As a second optional implementation, the step of comparing at least two of the MTU configuration value of the first interface, the MTU capability value of the first interface, the MTU configuration value of the second interface, and the MTU capability value of the second interface according to the second MTU negotiation strategy to obtain the target MTU value of the first interface includes:

[0113] When the second MTU negotiation strategy is an intermediate capability MTU value negotiation strategy, the MTU configuration value of the first interface and the MTU configuration value of the second interface are compared to obtain the larger MTU configuration value and the smaller MTU configuration value.

[0114] The larger MTU configuration value is compared with the MTU capability value corresponding to the smaller MTU configuration value, and the smaller comparison value is obtained;

[0115] The smaller comparison value is taken as the target MTU value of the first interface.

[0116] In this implementation, when using the intermediate capability MTU value negotiation strategy (referred to as the intermediate capability strategy), the smaller of the interface capability values ​​between the larger and smaller configuration values ​​is used as the target MTU value. Specifically, the MTU configuration value MTU1 of the first interface is compared with the MTU configuration value MTU2 of the second interface. If MTU1 is greater than MTU2, then MTU1 is compared with the MTU capability value MTU2' of the second interface. If MTU1 is greater than MTU2', then MTU2' is used as the target MTU value of the first interface. If MTU1 is less than or equal to MTU2', then the target MTU value of the first interface remains MTU1.

[0117] If MTU1 is less than MTU2, compare the MTU capability value MTU1’ of the first interface with MTU2. If MTU1’ is greater than MTU2, then use MTU2 as the target MTU value of the first interface. If MTU1’ is less than MTU2, then use MTU1’ as the target MTU value of the first interface. If MTU1’ is equal to MTU2, then use MTU1’ or MTU2 as the target MTU value of the first interface.

[0118] For case 1 in Table 2, MTU1 < MTU2 and MTU1 < MTU2’, and the smaller value between the interface capability values of the larger configuration value and the smaller configuration value is MTU1 = 4600. Finally, the target MTU configuration value of the first interface is negotiated to remain unchanged (4600), and the target MTU value of the second interface of the second network element = MTU2 = MTU1 = 4600;

[0119] For case 2 in Table 2, MTU1 < MTU2 and MTU1 > MTU2’, and the smaller value between the interface capability values of the larger configuration value and the smaller configuration value is MTU2’ = 3000. Finally, the target MTU value of the first interface of the first network element = MTU1 = MTU2’ = 3000, and the target MTU value of the second interface of the second network element = MTU2 = MTU2’ = 3000.

[0120] Table 2

[0121] Strategy MTU1 MTU1' MTU2 MTU2' Case 1 Intermediate capability strategy 4600 9600 1500 6000 Case 2 Intermediate capability strategy 4600 9600 1500 3000

[0122] As a third alternative implementation method, according to the second MTU negotiation policy, compare at least two of the MTU configuration value of the first interface, the MTU capability value of the first interface, the MTU configuration value of the second interface, and the MTU capability value of the second interface to obtain the target MTU value of the first interface, including:

[0123] When the second MTU negotiation policy is the maximum capability MTU value negotiation policy, compare the MTU capability value of the first interface and the MTU capability value of the second interface to obtain the smaller MTU capability value;

[0124] Use the smaller MTU capability value as the target MTU value of the first interface.

[0125] In this implementation method, the maximum capability MTU value negotiation policy (abbreviated as the maximum capability policy) is adopted, that is, the smaller value among the capability values is used as the target MTU value of the first interface. If the MTU capability value MTU1’ of the first interface is greater than the MTU capability value MTU2’ of the second interface, then use MTU2’ as the target MTU value of the first interface. If MTU1’ is less than or equal to MTU2’, then use MTU1’ as the target MTU value of the first interface.

[0126] For example, for case 1 in Table 3, 6000 is taken as the target MTU value of the first interface;

[0127] For case 2 in Table 3, 3000 is taken as the target MTU value of the first interface.

[0128] Table 3

[0129] Strategy MTU1 MTUI MTU2 MTU2' Case 1 Maximum capacity strategy 4600 9600 1500 6000 Case 2 Maximum capacity strategy 4600 9600 1500 3000

[0130] It should be noted that the second network element management unit determines the MTU configuration value of the second interface in the same way according to the above-mentioned second MUT negotiation strategy.

[0131] In addition, in this embodiment of the invention, after the first network element management unit determines the target MTU value of the first interface, it notifies the first network element, the network element IP packets, and each protocol to use the target MTU value as the protocol MTU.

[0132] In one embodiment of the present invention, the MTU configuration value and capability value of the network element interface (the aforementioned first interface and second interface) can be indicated by the Type-Length-Value (TLV) in the Link Layer Discovery Protocol (LLDP) message. The format of the LLDP message is shown in Tables 4 and 5.

[0137]

[0138] Among them, the strategies of Bit14 to 15 are enumerated, such as 00 representing the minimum value strategy, 01 representing the intermediate capability strategy, 10 representing the maximum capability strategy, and 11 being reserved.

[0139] In another embodiment of the present invention, the configuration MTU value and the maximum MTU value are obtained through the interface using the Netconf management method, as shown in Table 6.

[0141]

[0142] In this embodiment of the invention, the first network element management unit sends first MTU negotiation information containing a first MUT negotiation strategy to the second network element management unit, obtains the second MTU negotiation strategy indicated by the priority of the first MTU negotiation strategy from the second network element management unit, and determines the target MTU value of the first receiving or the second interface based on the second MTU negotiation strategy. In this way, the purpose of determining the target MTU value of the interface based on the MTU negotiation strategy negotiated by the two is achieved.

[0143] like Figure 2 As shown, this embodiment of the invention also provides a method for determining transmitted information, including:

[0144] Step 201: The second network element management unit obtains the first maximum transmission unit (MTU) negotiation information sent by the first network element management unit.
