Embodiment 1

[0061] An embodiment of the present invention provides a switching processing method for elastic network interconnection DRNI, figure 2 It is the flow of the handover processing method of the elastic network interconnection DRNI according to the embodiment of the present invention Figure 1 ,Such as figure 2 As shown, the process includes the following steps:

[0062] Step S202, one end of the DRNI receives a service switching request sent by the opposite end;

[0063] Step S204, determining the in-device system where the service gateway corresponding to the service switching request is located;

[0064] In step S206, the DRNI side obtains a switching response message in response to the service switching request from the determined intra-end system, and sends the switching response message to the peer end.

[0065] Through the above steps, the practice of only link switching but no service switching in the in-terminal system in the related technology has been changed, and...

Embodiment 2

[0071] An embodiment of the present invention provides a switching processing method for elastic network interconnection DRNI, image 3 It is the flow of the handover processing method of the elastic network interconnection DRNI according to the embodiment of the present invention Figure II ,Such as image 3 As shown, the process includes the following steps:

[0072] Step S302, the DRNI end receives a link switching request or a service switching request;

[0073] Step S304, judging whether one end of the DRNI includes multiple in-end systems, and if so, starting a response timer;

[0074] Step S306, when the response timer expires, the DRNI side sends a handover response message.

[0075] In the case of a service switching request or a link switching request, it is first judged whether one end of the DRNI is a multiple in-device system or a single in-device system. If it is a single end system, it will directly send a handover response message, otherwise start the respo...

Embodiment 3

[0077] An embodiment of the present invention provides a switching processing method for elastic network interconnection DRNI, Figure 4 It is the flow of the handover processing method of the elastic network interconnection DRNI according to the embodiment of the present invention Figure three ,Such as Figure 4 As shown, the process includes the following steps:

[0078] Step S402, the in-device system at one end of the DRNI sends a service switching request, wherein the service switching request carries a service identifier;

[0079] Step S404, the in-device system receives the switching response message in response to the service switching request, and switches the corresponding service from the aggregation link to be switched to another aggregation link according to the service identifier carried in the switching response message.

[0080] Preferably, the corresponding service includes one or more services.

Abstract

The invention discloses a DRNI switchover processing method and device. The DRNI switchover processing method includes the steps that a DRNI end receives a service switchover request sent by an opposite end; an in-end system where a service gateway corresponding to the service switchover request is located is determined; the DRNI end acquires a switchover response message responding to the service switchover request from the determined in-end system and sends the switchover response message to the opposite end. The DRNI switchover processing method and device achieve the purpose of DRNI flow switchover and have the advantage of guaranteeing effective service transmission.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for switching processing of distributed elastic network interconnection DRNI. Background technique [0002] With the rapid development of broadband services, more and more interconnections between networks are used to carry more services. According to the technology adopted in the network, there are many ways to protect the link and the system on it. As the demand for traffic protection becomes stronger and higher, some operators have also raised the need to protect the network interconnection area. The protection can be realized by means of port aggregation, and the commonly used methods can be port aggregation or loop protection. The ring network protection technology is limited by the network topology, and it is not applicable to the whole network connection method for the network interconnection part. IEEE's existing standard 802.1AX-Link Aggregation c...
