Abstract

A multicast session directory is a mechanism by which users can discover the existence of multicast sessions. In the Mbone, session announcements have also served as multicast address reservations - a dual purpose that is efficient, but which may cause some sideaffects as session directories scale. In this paper we examine the scaling of multicast address allocation when it is performed by such a multicast session directory. Despite our best efforts to make such an approach scale, this analysis ultimately reveals significant scaling problems, and suggests a new approach to multicast address allocation in the Internet environment. 1 Introduction A multicast session directory is a mechanism by which users can discover the existence of multicast sessions, and can find sufficient information to allow them to join a multicast session. Such a session is minimally defined by the set of media streams it uses (their format and transport ports), by the multicast addresses and scope of those str...
