Problems solved by technology

[0009] The technical problem to be solved by the present invention is: to overcome the disadvantage that the node identification in the prior art ASON network has dual attributes, and when the IP address of the control plane is modified, the original service will be affected, and a method for accessing nodes in the automatic switching optical network is provided , so that when the IP address of the control plane is modified, the original business will not be affected

Embodiment Construction

[0029] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0030] When the node identifier identifies both the service ID and the node IP address, if the node IP address is modified, the service ID will also be changed, which will affect the service. In view of the above-mentioned shortcomings, the present invention configures node identification and control plane address (i.e. node IP address) for each node, by mapping the relationship between node identification and control plane address, the node IP address can be easily modified without affecting the existing business.

[0031] As shown in FIG. 2 , the present invention configures node A with a node ID of 1.1.1.1 and a control plane address of 172.16.1.1, and other nodes are similar. Each node establishes a mapping relationship between the node ID and the control plane address, for example, the one-to-one correspondence relationship from the node ID to the co...

Abstract

The method comprises: configuring node ID and node IP address for each node, and building mapping relation between the node ID and the node IP address; releasing the mapping relation between the node IP and the node IP address to make other nodes get the mapping relation and save the IP relation; when visiting other nodes, using the mapping relation between the node ID and node IP address maintained by current node to switch the node ID into the node IP address to visit. The invention overcomes the issue existed in current ASON network, which is when modifying control plane IP address, the original service will be influenced.

Description

technical field [0001] The invention relates to the technical field of automatic switching optical network, in particular to a node access method in automatic switching optical network. Background technique [0002] Automatically switched optical network (ASON) adds a control plane to the traditional optical network and proposes the concept of switched connections. The nodes of the optical network first obtain the connection relationship between the local network element and other optical network elements through the local link discovery technology, and then publish their node and link status through the control plane, and receive the status release of other network elements in the network. Finally, every Each optical network element has a "network map" that describes the precise topology of the network. The "network map" includes various information such as nodes, links, and resources. [0003] When a node is required to establish a connection by a client device or a manag...
