<p>A route query method in ASON for implementing the route query by the network element NE1 which has a protocol controller PC and a connection controller CC but without a routing controller RC, includes: NE1 sends a Route Request signaling to the remote NE2, then NE2 obtains the Route Response according to the Route Request, and returns the Route Response signaling to NE1 which launches the Route Request by a Route Response signaling; the PC of NE1 sends the Route Response to the CC of local network element after receiving the Route Response signaling. The method of the present invention enables the route query to be done in case that the local NE hasn't a RC by interacting with the remote network element through signaling, meanwhile, is compatible with the prior route query technique, easy and reliable. The invention can be implemented in the field of data and ASON. ® KIPO & WIPO 2009</p> |
