Hop count between N12 and O-N3 is 4;If the IP layers control network element determines the 2nd UNI links between O-N4 and IP-N14
For the 3rd UNI links, then photosphere control network element 300 can retain O-N4, O-N8, O-N9, O-N12 in former photosphere operating path
The path of composition, if the 2nd UNI links between O-N8 and IP-N12 are defined as the 3rd UNI chains by IP layers control network element
Road, then photosphere control network element 300 can retain the path that O-N8, O-N9, O-N12 in former photosphere operating path are formed, successively
Analogize, it is known that, when IP layers control network element determines the corresponding 2nd UNI links of the minimum O-N4 of the hop count between O-N3
For the 3rd UNI links when, photosphere control network element 300 can retain former photosphere operating path to large extent.
In adjacent node is also served as into the implementation of the node relevant with former photosphere operating path, alternatively, the
Three determining modules 34 can be with according to whether distinguish corresponding to the second photosphere node of same number of hops on former operating path
The photosphere adjacency of two UNI links and the first UNI links.Alternatively, in hop count under the same conditions, on operating path
The photosphere adjacency of 2nd UNI links corresponding to node and the first UNI links twoth UNI corresponding higher than adjacent node
The photosphere adjacency of link and the first UNI links, or, the 2nd UNI links and institute corresponding to the node on operating path
State light of the photosphere adjacency less than the 2nd UNI links corresponding to adjacent node and the first UNI links of the first UNI links
Layer adjacency.
For example, as shown in Figure 1 b, it is assumed that the UNI link failures between O-N3 and IP-N4, second determines optical module 32
It is determined that at least one second photosphere node that is relevant with the former photosphere operating path and having UNI links has:O-N4、O-N8、O-
N12, O-N5, O-N7, wherein, O-N4, O-N8, O-N12 are the node on former photosphere operating path, and O-N5, O-N7 are and former light
The adjacent node of node on layer operating path;Hop count between O-N4 and O-N3 is 1, the jump between O-N5, O-N8 and O-N3
Number is that hop count of the hop count between 3, O-N12 and O-N3 between 2, O-N7 and O-N3 is 4;
If the photosphere adjacency of the 2nd UNI links and the first UNI links is higher than corresponding to the node on operating path
