Embodiment 1

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

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

[0045] Wherein, this embodiment is pre-configured as follows: Message Type takes a value of 0, indicating 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 pres...

Abstract

The invention discloses a message loopback method. The method includes: the loopback source node sends a Loopback Request for requesting a loopback operation through the current test path, and the Loopback Request contains information indicating the type of the message to be looped back. The loopback type field; the loopback destination node on the current test path receives the Loopback Request, judges whether a loopback message is needed according to the loopback type field therein, and if so, returns to the loopback source node to indicate a loopback status update Successful LoopbackReply; If not, return the Loopback Reply carrying routing information to the loopback source node; The loopback source node receives the Loopback Reply indicating that the loopback state update is successful from the loopback destination node, Then, the loopback of the message to be looped back is performed with the loopback destination node. The invention also discloses a message loopback system, which can avoid affecting the transmission of other business messages and the monitoring and management of paths, and can effectively improve the efficiency of message loopback testing.

Description

technical field [0001] The invention relates to message loopback technology, in particular to a message loopback method and system. Background technique [0002] For the current packet transmission network, when implementing the loopback (Loopback) function, there are mainly two situations: one is the full loopback (Full Loopback) technology under the non-service state (Out-of-service), this kind of Loopback technology mainly It is used to test the connection or related performance of the path. It is necessary to perform a loopback operation on all packets, so that all packets cannot be transmitted according to the normal business process, which affects the normal operation of the business; the other is in the non-interrupted business state Operation Administration and Maintenance (OAM, Operation Administration and Maintenance) Loopback technology under (In-service). This Loopback technology performs a loopback operation on all OAM packets. Although it does not affect the no...
