METHOD FOR SELECTING OPTIMAL PATH IN PRIVATE NETWORK OF NETWORK INTERFACE NETWORK

摘要

A kind of purpose: method, for selecting an optimal path of PNNI standards (PNNI) network, it is arranged to search for optimal path, it meets the service quality from a subscriber requests, is counted by the primary information retrieval for primary complete network by the generalized calls admission control (GCAC) and a subscriber plant factor (SPF) for the division being unified in single step. Construction: a kind of method includes the following steps: for selecting an optimal path in PNNI standards (PNNI) network: deciding whether that a node and a connection meet the service quality from a subscriber requests, by giving each node and connection for change; For node and connection, executes shortest path and calculate. Method further gives a node below and connection for change in addition to a node and a connection, makes service quality dissatisfied in shortest path account.
