Closed Conference Signalling Using the Session Initiation Protocol.
Peer reviewed Peer reviewed
Miladinovic, Igor; Stadler, Johannes – Internet Research, 2003
Introduces an extension of the Session Initiation Protocol (SIP) for closed multiparty conferences; the extension expands SIP for discovery of participant identities in a conference, and ensures that each participant is notified before a new participant joins. Verifies this extension by applying it to two SIP conference models. Concludes with an…

A Stateful Multicast Access Control Mechanism for Future Metro-Area-Networks.
Peer reviewed Peer reviewed
Sun, Wei-qiang; Li, Jin-sheng; Hong, Pei-lin – Internet Research, 2003
Multicasting is a necessity for a broadband metro-area-network; however security problems exist with current multicast protocols. A stateful multicast access control mechanism, based on MAPE, is proposed. The architecture of MAPE is discussed, as well as the states maintained and messages exchanged. The scheme is flexible and scalable. (Author/AEF)
