Abstract

A conference connection method for use in a multicast packet switching network. Once the packet switches and inter-switch links to comprise a multicast connection among three or more endpoints are determined, a check is performed to determine whether that multicast connection would to usable to effect communication in accordance with a specified transmission matrix and meeting a packet sequencing condition. The multicast connection is established only when the check indicates that the connection would meet both requirements.
