Embodiment 3

[0159] Embodiment 3 and Embodiment 4 refer to Embodiment 1 and Embodiment 2 for specific implementation.

[0160] The method for measuring frame loss of aggregated links described in conjunction with the examples disclosed in this application may be directly embodied as hardware, a software module executed by a processor, or a combination of both. For example, figure 1 and Figure 5 One or more functional block diagrams and / or one and / or multiple combinations of the functional block diagrams shown in the functional block diagram (for example, correcting the received packet counting unit) can correspond to each software module of the computer program flow, or can be Corresponds to each hardware module. These software modules can respectively correspond to Figure 6 and Figure 7 steps shown. These hardware modules, for example, can be realized by solidifying these software modules by using a Field Programmable Gate Array (FPGA).

[0161] The software module can be located...

Abstract

The invention discloses an aggregation link frame loss measurement device and a method. The device used for a source MEP comprises a frame sending module, a frame receiving module and a frame loss measurement module, wherein the frame sending module is used for successively sending a plurality of data measurement frames carrying sending sequence information to an objective MEP, and sending a frameloss measurement frame carrying the sending sequence information to the objective MEP when a frame loss measurement period node is reached; the frame receiving module is used for receiving a frame loss measurement response frame sent by the objective MEP and acquiring a corrected objective MEP end package receiving counting value from the frame loss measurement response frame; and the frame lossmeasurement module is used for carrying out frame loss measurement based on the corrected objective MEP end package receiving counting value. In the invention, a problem that measurement is inaccuratebecause of frame loss caused by a disorder problem during frame receiving is effectively solved.

Description

technical field [0001] The present invention relates to the field of link aggregation communication, in particular to an aggregation link frame loss measurement device and method. Background technique [0002] The G.8013-201508 draft of ITU-T (ITU-T for ITU Telecommunication Standardization Sector, International Telecommunication Union Telecommunication Standardization Branch) mentions the method of frame loss measurement (ETH-LM) in the case of link aggregation, which In the method, due to the frame loss measurement frame LMM and frame loss measurement response frame LMR and data measurement frame at one end in the actual measurement, the aggregation link will select one of the links according to different policies and send it to the opposite end MEP (Maintenance entity group End Point, the end point of the maintenance entity group), so the sequence to the peer MEP cannot be guaranteed, and out-of-sequence problems may occur, resulting in inaccurate measurement of frame los...
