Network control arrangement for processing a plurality of connection requests.

摘要

A network control arrangement where two or more path hunt operations are performed in parallel using one or both of two techniques: 1) reading a memory for a second path hunt operation during the time that information read from the memory for a first path hunt operation is being processed to select a path, and 2) maintaining duplicate memories and reading from them both to perform two path hunt operations before either memory is updated. A disjoint path check unit rapidly determines whether any of the network paths from a first inlet to a first outlet conflict with any network paths from a second network inlet to a second outlet. Plural path hunts are performed only when there is no conflict.
