The use of tina principles in the management of internet multimedia conferences

Abstract

This paper shows how some of the TINA principles used in the development of Service Management techniques for the Broadband ISDN may be applied to the management of Internet Services. In the original B-ISDN concept of these services, it was assumed that there would be B-ISDN components in both the network and subscriber systems. In the Internet version of the services, it was considered that IP Multicast would be used for the multimedia conferencing services. In the approach adopted here, the normal Internet functionality is maintained unchanged in the subscriber equipment; modifications in the access network dealt with the differences between the BISDN and the Internet. The paper discusses the architecture adopted, the applications services integrated and the methods employed to demonstrate remotely the system. The latter encompassed the novel use of Direct Broadcast Satellite connectivity, for the purposes of the demonstration.
