Embodiment Construction

[0022] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] refer to figure 1 As shown, the specific steps are as follows:

[0024] 1. Check the MESSAGE_ID object in the received refresh message.

[0025] Step 1: Determine whether node B has received the refresh message sent by node A.

[0026] When node B receives the refresh message, it checks the MESSAGE_ID object in the refresh message. If all the MESSAGE_IDs in the refresh message are the MESSAGE_IDs generated when the path was created before, then node B sends an ACK message to node A in response. Here setting MESSAGE_ID=1 is the MESSAGE_ID generated by creating the route. If MESSAGE_ID=1 in the refresh message, the MESSAGE_ID object received by node B is generated when the path is created, node B sends an ACK message to node A in response, the MESSAGE_ID object in the ACK message is 1, and the ACK message type is 13 (standard ACK messag...

Abstract

This invention discloses a method for processing messages of maintaining links of O-UNI system including: a node receives a refresh message containing the address of a source node, the address of an aim node and MESSAGE-ID and checks the MESSAGE-ID in it to get the address of the source node, the address of the aim node and MESSAGE-ID, in which, the source node address received is the aim addressfor transmitting simplified refresh message and the aim address is the source address for transmitting it, the kind of the message and ctype kind MESSAGE-ID for transmitting the simplified refresh message are filled in to transmit it.

Description

technical field [0001] The invention relates to a message processing method for maintaining link state in an O-UNI system, in particular to a message processing method for link maintenance of the O-UNI system. Background technique [0002] ASON (Automatically Switched Optical Network) refers to a new generation of optical network that completes the automatic switching function under the control of routing and signaling, and can also be regarded as a standardized intelligent optical transport network. In ASON, services can be dynamically connected, and time slot resources can also be dynamically allocated. At the same time, it supports different technical solutions and different service requirements, and has the characteristics of high reliability and high scalability. For operators, with ASON, the allocation of network services will become more flexible, and voice signal transmission, IP service transmission, ATM signal transmission, and digital image signal transmission can...
