Conference connection method in a multicast packet switching network
First Claim
1. A method for use in an arrangement comprising a multicast packet switching network for communication among a plurality of communication endpoints, said communication comprising transmission of packets, said network comprising a plurality of packet switches interconnected by a plurality of inter-switch links, each of said endpoints connected to one of said packet switches, said method comprisingprior to transmitting said packets, determining a set of said packet switches and a set of said inter-switch links to comprise a multicast connection through said network for communication among a set comprising at least three of said endpoints,checking whether said multicast connection would be usable to effect communication among said set of endpoints in accordance with a specified transmission matrix and meeting a packet sequencing condition;
- andestablishing said multicast connection only when said checking indicates that said multicast connection would be usable to effect communication among said set of endpoints in accordance with said specified transmission matrix and meeting said packet sequencing condition.

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.

13. A method for use in an arrangement comprising a multicast packet switching network for communication among a plurality of communication endpoints, said communication comprising transmission of packets, said network comprising a plurality of packet switches interconnected by a plurality of inter-switch links, each of said endpoints connected to one of said packet switches, said method comprising
prior to transmitting said packets, determining a set of said packet switches and a set of said inter-switch links to comprise a multicast connection through said network for communication among a set comprising at least three of said endpoints, checking whether said multicast connection would be usable to effect communication among said set of endpoints meeting a packet sequencing condition, and establishing said multicast connection only when said checking indicates that said multicast connection would be usable to effect communication among said set of endpoints meeting said packet sequencing condition.
