Abstract
A connection procedure for finding by rearrangement a path for multirate, multicast traffic through an SDH cross-connect with subnetwork connection protection. If no free path for a new payload through the SDH switching hardware is available, the switching procedure looks for a path that is adequate and blocked by the least existing payload capacity. If the hunt is successful, the procedure rearranges the existing connections to make possible a path for the new payload. The procedure does not interrupt the existing connections; thus it is a 'hitless' procedure. Connections for existing payloads that must be moved to make way for the new payload are queued and the connection procedure is applied recursively, to each in turn, until the queue is empty.
