Scope

This amendment to ITü-T Rec. X.234 (1994) I ISO/IEC 8602: 1995 provides the capability to the connectionless-mode Transport protocol to support multicast PDU transfer when used in conjunction with the multicast services of the connectionless-mode Network service. The protocol for providing the connectionless-mode Transport service is contained entirely in ITU-T Rec. X.234 I ISOAEC 8602. ITU-T Rec. X.234 I ISO/IEC 8602 restricts the connectionless-mode Transport to the case of exchanging TPDUs between one sending TS-user and one receiving TS-user. Subnetwork standards exist which support the transfer of a SDU from one entity to a number of other entities in a single logical operation. Work is on-going to develop the capabilities for exchanging multicast PDUs at the Network layer. This amendment is directed at providing multicast Transport service via multicast capabilities of the Network service if they are available. With the current ïïü-T Rec. X.234 I ISOAEC 8602, no Transport layer capabilities are described to utilize such multicast Network services. This amendment defines additional assumptions concerning the services optionally provided by the Network layer and adds no new functions of its own.
