Path Control Method Using Bandwidth Reservation Link Grouping Algorithm in Fully Distributed Asynchronous Transfer Code Switching System

摘要

The present invention relates to an outgoing and called party path control method using a band reservation link grouping algorithm in a fully distributed ATM switching system, and to efficiently perform routing in a large-capacity fully distributed ATM switching system. In order to provide the calling and called party path control method using the bandwidth reservation link grouping algorithm, the number of bands required by the new call is variable B, the type of connection required is variable S, the amount of switch bands is variable V, and the link By assigning the initial value of the group identifier to the variable LG and setting up a link that satisfies the call request band for each link group according to the one-way or two-way connection type, the band is weakened in the outgoing link management table and the response is received from the called party. Source processing steps (100 to 129) for receiving and updating the outgoing link band management table; The number of bands required by the call is variable B, the type of connection required, variable S, the switch link identifier variable V, and the link group identifier variable LG, respectively, by assigning initial values to the unidirectional or bidirectional connection types. Efficient routing is performed in a large-capacity, fully distributed ATM switching system, including a called party processing step (200 to 218) for updating a destination link band management table by setting a link satisfying a call request band for each link group. It can work.
