Two Multiparty Connection Establishment Procedures For Broadband ISDN

We present two approaches for the multiparty connection estalblishment procedure, used to set up end-to-end physical connections for data transfer, in Broadband Integrated Service Digital Network (BISDN) signaling systems. In these systems, the connection may include more than two members, as for video conferencing, the requested bandwidth may differ for different traffic requirements and the terminal types of end stations may be incompatible, as for NTSC and HDTV. These requirements complicate the connection finding and the connection establishment procedure. In this paper, we focus on the connection establishment control and propose three connection management procedures: a threading approach and a concurrent approach which are based on a centralized connection finding scheme. A brief comparison among these approaches is also provided. Some of these protocols and a proposed resource allocation algorithm within the central office are implemented as part of the project Experimental ATM Network and Services Environment (EXPANSE) at Bell Communications Research CBellcore).
