Method for processing connection resource competition in automatic switched optical network

[0033] Example 1:

[0034] as attached Figure 5 ASON shown.

[0035] 1. When the network is initialized, configure the link through the network management The contention decision parameter of the C terminal is 8, which is stored in the C node, and the link The contention decision parameter of the F-side of , is 5, which is stored in the F-node.

[0036] 2. The network initiates two connection requests at the same time, one is connection 1: A->H, the route is A->C->F->H; the other is connection 2: G->B, the route is G->F ->C->B. A segment of two connections with overlapping routes is a link. .

[0037] 3. When the connection 1 passes through the C node, the link is allocated resource No. 2, while carrying the link in the signaling The contention decision parameter value of the C terminal is 8, and the signaling is transmitted to the downstream node F; similarly, when the connection 2 passes through the F node, the link is allocated resource No. 2, while carryi

[0040] Embodiment 2:

[0041] If the value of the competition decision parameter at both ends of the link remains the same, it will cause the connection in one direction to obtain resources in the competition, while the connection in the other direction always fails, which will cause unfairness. In order to improve this phenomenon and make the resource allocation conflict resolution relatively fair, the competition decision parameters at both ends of the link can be dynamically changed, for example, the network management can adjust it according to the network conditions and so on. In addition, certain rules can also be used to automatically adjust the contention decision parameters at both ends of the link. An implementation is given below.

[0042] 1. Set a contention failure counter for each link in the control nodes at both ends of the link, and set a threshold for the counter at the same time.

[0043] 2. The counter is incremented by 1 each time a connection passi
