Embodiment 1

[0043] In this embodiment, a specific implementation of the message loopback method of the present invention will be described in detail.

[0044] In this embodiment, the message structure of Loopback Request is as follows figure 2 As shown, the Loopback Request can include the following fields: the operation type (OperationType) used to indicate the current Loopback Request type, the message type (Message Type) used to indicate the loopback type operation, and the type used to indicate the current loopback report type Loopback Type (Loopback Type). In addition, the Loopback Request also contains a TTL field ( figure 2 Not shown).

[0045] Among them, this embodiment is pre-configured as follows: The value of Message Type is 0, which means that the message type is a request message; Operation Type is used to indicate whether the current operation type is to perform loopback or delete loopback, which can be preset When the value of Operation Type is 1, it means that loopback is t...

Abstract

The invention discloses a looping back method of a message, which comprises the following steps of: transmitting a Loop-back Request for requesting to perform loop-back operation by a loop-back source node via a current test path, wherein the Loop-back Request comprises a loop-back type field for presenting the type of the message to be looped back; receiving the Loop-back Request by a loop-back destination node on the current test path, and judging whether the message needs to be looped back according to the loop-back type field in the Loop-back Request; if the message needs to be looped back, returning a Loop-back Reply that means the loop-back state is successfully updated to the loop-back source node; if the message does not need to be looped back, returning the Loop-back Reply that carries the routing information to the loop-back source node; receiving the Loop-back Reply returned by the loop-back destination node, which represents that the loop-back state is successfully updated by the loop-back source node, then looping back the message to be looped back between the loop-back source node and the loop-back destination node. The invention also discloses a looping back system of the message, which can avoid the influence on the transmission of other service message and the monitoring and management of the path, and also improve the efficiency of the message loop-back test effectively.

Description

Technical field [0001] The invention relates to a message loopback technology, in particular to a message loopback method and system. Background technique [0002] For the current packet transport network, when implementing the loopback function, there are mainly two situations: one is the full loopback technology in the out-of-service state, and the loopback technology is mainly It is used to test the connection or related performance of the path. All messages need to be looped back, so that all messages cannot be transmitted in accordance with the normal business process, which affects the normal operation of the business; the other is in the uninterrupted business state (In-service) Operation Administration and Maintenance (OAM, Operation Administration and Maintenance) Loopback technology, the Loopback technology is to loop back all OAM messages, although it does not affect the normal transmission of other messages such as business flows, but Because all OAM packets need to ...
