Embodiment Construction
[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0036] The problem to be solved by the present invention is how to realize the resource separation of the main and backup services in the three situations of different sources but the same host, the same source and different hosts, and different sources and different hosts. figure 1 It is a block diagram of a control plane control block of a single node of a grid network involved in the method of the present invention. Such as figure 1 As shown, usually the control plane on a single node is composed of five functional modules: business management, routing calculation, signaling control, routing flooding, and resource management. These five modules are known prior art, and the method of the present invention needs to be carried by a hardware control unit having the functions of the block diagram. The five functional modules themselves may correspond to one har...

Separation method for active-standby service resource of different source and sink for grid network is as follows: 1 source node service management module receives establish request of first service, triggers routing computing module for computing route; signal control module starts to establish the first service; 2 routing flooding module completes resource mark information update; 3 source nodeservice management module receives establish request of second service, triggers routing computing module for computing route according to active-standby service resource separation strategy; 4 signal control module starts to establish the second service; 5 routing flooding module completes resource mark information update. The inventive method can process active-standby service resource separation of three conditions: different source but same sink, same source but different sink, and different source and different sink; the method can be applied network combined by grid network and ring networking, or independent grid network; the method is highly reliable and stable.
Description
technical field [0001] The invention relates to the separation of active and standby service resources in a grid network, specifically a method for separating non-homologous and same-master standby service resources in a grid network. Background technique [0002] In recent years, with the rapid development of automatic switching optical network technology, it has brought many automatic control methods to optical networks, such as: automatic neighbor discovery, automatic topology discovery, etc., and the changes brought about in the reliability of optical networks are also huge. [0003] The introduction of the control plane requires automatic switching of optical network nodes (for example: SDH-based optical crossover nodes) with distributed processing functions. The distributed processing function makes it possible to realize the recovery of the grid network. The centralized recovery in the grid network has not been widely used because of its long recovery time (minute le...
