Embodiment 3

[0159] For the specific implementation of the third embodiment and the fourth embodiment, refer to the first embodiment and the second embodiment.

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

Abstract

The present invention discloses a device and method for measuring frame loss of aggregated links. The device for using the source MEP includes: a frame sending module, which is used to send multiple data measurement frames carrying sending order information to the destination MEP in sequence; When the frame loss measurement cycle node is used, the frame loss measurement frame carrying the sending order information is sent to the target MEP; the frame receiving module is used to receive the frame loss measurement response frame sent by the target MEP, and the frame loss measurement response frame is received from the frame loss measurement response frame. Obtaining a corrected count value of received packets at the destination MEP in the frame; a frame loss measurement module configured to perform frame loss measurement based on the corrected count value of received packets at the destination MEP. The invention effectively solves the problem of inaccurate measurement of frame loss caused by disordered frame receiving time.

Description

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