Embodiment Construction

[0084] The core of the present invention is to define the P2MP multicast performance parameter in Ethernet based on the multicast path, and provide P2MP multicast performance measurement support in Ethernet OAM, so as to be the same as the unicast performance parameter, at the OAM plane from frame loss rate, frame delay , Frame delay variation to evaluate Ethernet P2MP multicast performance.

[0085] In order to facilitate the understanding of the present invention, specific implementations of the present invention will be described below.

[0086] The present invention first needs to define P2MP multicast performance parameters in the specific implementation process, so that the measurement of corresponding performance parameters can be carried out according to the defined content in the subsequent process;

[0087] Defining P2MP multicast performance parameters is also implemented from three aspects: frame loss, frame delay and frame delay variation. The P2MP multicast perf...

Abstract

This invention relates to a detecting network multicast performance method. The invention mainly includes: firstly, at the test starting point, construct and send the multicast performance measurement request packet with the identification information; then, at each node receiving the said multicast performance measurement request packet, respectively send the performance measurement response packet with the said identification information to the test starting point; finally, in the scheduled time, the test starting point receives the said performance measurement response packet, and according to the identification information, measure the multicast performance parameters. The invention makes small change to the OAM frame format defined in Y.17ethoam, and in the realization of the invention, the process in the sending point and the receiving point is rather simple, and based on the original unicast performance measurement calculation method, it processes the calculation method of multicast performance measurement. Therefore, the invention can be nice to achieve P2MP multicast performance parameter measurement in the Ethernet OAM, thereby assisting OAM to provide a more comprehensive network performance assessment.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a multicast performance detection technology in Ethernet OAM (operation management and maintenance). Background technique [0002] With the development of network communication technology, Ethernet (Ethernet) technology gradually develops from local area network to metropolitan area network with its high cost performance advantage, and its port rate also develops from 10M to 10G. In the process of the development of Ethernet to the metropolitan area network, it is required that the Ethernet technology must meet the carrier-class network requirements. Among them, OAM is the basic requirement of carrier-class network for various technologies. The corresponding OAM mainly includes a network fault management mechanism and a network performance management mechanism. [0003] Currently, fault / performance management mechanisms for the ETH network include: [0004] Based...
