It is interdigital to be less than predetermined value with the time, determine the routing by source OTU, the first OP, purpose the OTU OXC connected and purpose OTU.
Whether the two ways is connected to the 2nd OP according to purpose OTU, is divided into two when source OTU is connected to an OP
Kind mode improves the definite accuracy of routing of knowing clearly to determine routing.
In above-mentioned preferred embodiment, when the source, OTU is not connected to the first OP, and the OXC's that source OTU is connected is interdigital
It is less than predetermined value with the time, whether the 2nd OP is connected to according to purpose OTU, is divided into two ways and realizes the definite routing：
Mode one：Judge that purpose OTU is connected to the 2nd OP, determine OXC that routing connected by source OTU, source OTU,
2nd OP and purpose OTU；
Mode two：Judge that purpose OTU is not connected to the 2nd OP, and judge the friendship for the OXC that purpose OTU is connected
It is interdigital to be less than predetermined value with the time, determine OXC and mesh that routing is connected by OXC, purpose OTU that source OTU, source OTU are connected
OTU.
The two ways is not connected to the first OP in source OTU, and the interdigital of the OXC that source OTU is connected is less than with the time
Whether predetermined value, be connected to the 2nd OP according to purpose OTU and be divided into two ways and determine routing, improve routing determine it is accurate
Property.
As a preferably embodiment, in step S402, by flooding process to path control deivce RC or road
Footpath computing unit PCE notifies whether the optical transceiver is connected to the interdigital of light protection location OP and/or light Cross module OXC
With the time.The preferred embodiment is by flooding process notice and the connection relation of OP and interdigital matches somebody with somebody the time.
