Round trip method

Abstract

A method to achieve the return, it is: sets sign information of every maintenance end, loads the sign information of the maintenance end with return aim in the multi-broadcast return information by the maintenance end, send; receives the return answer information that sends by the every maintenance end of the return information according to the maintenance end sign information that loads in the return information. The invention provides a new mechanism of the return, avoids the process that needs to write the maintenance end address information with return aim when MEP sends the return information, the invention can achieve return to the certain prearrange maintenance end with pertinence, thereby achieve perfect the return function of the Ethernet OAM solving project, improves the practical aim of the return method.

Description

technical field [0001] The invention relates to the technical field of network testing, in particular to a loopback implementation method. Background technique [0002] At present, two groups, ITU-T (International Telecommunication Union Telecommunication Standardization Sector) and IEEE (Institute of Electrical and Electronics Engineers), are simultaneously conducting research on the end-to-end OAM (operation, management and maintenance) function of Ethernet, among which ITU-T is in Y.1730 The end-to-end OAM function of Ethernet is described in the two documents of Y.71ehtoam and end-to-end OAM function of Ethernet in the 802.1ag document of IEEE. In the above documents, the ideas of the two organizations are generally the same, and the solutions for OAM functions are also very similar. Among them, the ITU-T documents include alarm and performance parts, which make the OAM system more complete. [0003] At present, the industry has reached a consensus on the basic OAM func...

Problems solved by technology

[0014] Since the OAM functions of Ethernet are independent of each other, obtaining the MAC address of the loopback destination maintenance point through methods such as CC (Continuity Check) and LT (Link Tracing) will make the OAM functions interdependent, so it cannot be obtained through CC , LT and other methods to obtain the MAC address of the LB destination maintenance point, and there is no method defined in the prior art to enable each MEP to know the MAC addresses of all MIPs on the network

Therefore, the implementation method of LB in the prior art cannot realize the LB function for all MPs in the network, and has implementation limitations
