Abstract — The Single Source Multicast (SSM) model has received considerable attention from the research community as it could finally bring a scalable solution for some multicast applications. In the SSM model it is the responsibility of the applications to tell the network what are their sources of interest. As a consequence, the SSM model is well suited for one to many multicast applications (such as TV and radio streaming) because there is only one source to discover and it is supposed to be well known. However there still does not exist an SSM session layer protocol and middleware in order to help Any Source Multicast (ASM) applications to discover the presence or departure of the SSM sources. In this paper, we propose a detailed architecture for such a source discovery session layer protocol. We have implemented our protocol as a middleware called Libemu and freely available as an open source library. I.

Introduction 1.2 Any Source Multicast 1.3 Source Specific Multicast The Source Specific Multicast, still under definition in [11], is intended to model the transmission of an IP datagram issued by a source (with IP address S) to a SSM group identified by an IP multicast address G (in the range 232/8 for IPv4). According to [2], the network service is a channel (S, G) to which receivers subscribe to receive the data from the source. The group has only one source but any number of receivers dynamically joining and leaving the session. 1.4 Application Level Multicast 1.5 Conclusion 1 Congestion Control Schemes for Multicast Transmission of Media Flows This chapter provides an analysis of congestion control schemes for the Source Specific Multicast (SSM) and the Application Level Multicast (ALM) service model. After discussing some key points of the congestion control, we comment on some state--of--art proposals. The original multicast service specified by S. Deering in [8] c
