A METHOD AND SERVER FOR DETERMINING THE DIRECT OPTICAL PATH AND A SYSTEM FOR ESTABLISHING THE DIRECT OPTICAL PATH

摘要

A method for determining the direct optical path is provided, and the method includes the following steps: based on the detected bandwidth occupied by each path and the router nodes passed by the path, obtaining the candidate pairs of nodes, the bandwidth between the candidate pairs of nodes exceeding the preestablished bandwidth threshold (101); based on the preestablished router selecting policy, selecting a pair of nodes as two ends of the direct optical path from the candidate pairs of nodes (102). A server for determining the direct optical path is also provided by the implementation of this invention. A system for establishing the direct optical path is also provided by the implementation of this invention. The network topology can be dynamically adjusted by implementing this invention, and the network source can be optimized.
