....satelliteterrestrial networks. We discuss the problems of the deployment of satellite links in the Internet for multicast delivery and we present some short term as well as long term solutions to overcome these problems. These solutions concerning the Internet Group Membership Protocol (IGMP) [5] feedback implosion problem and the construction of an eOEcient multicast tree that prots from the broadcast capability of the satellite. We present an algorithm that use an exponential feedback raise and which able to provide suOEciently stable expectation values across a large of group sizes. We ....

....link to an Internet host while data may be received on the UDL after it has been forwarded by one of the feeds. 3 IGMP over Satellite 3. 1 IGMP Overview IGMP is an integral part of IP that is used by IP hosts to report their host group memberships to any immediately neighbouring multicast router [5] . Hosts inform their local router of their intent to receive transmissions attached to a specic multicast group. The router would then periodically query the LAN to determine if group members are still active. Based on the group membership information learned from IGMP, the router joins a ....

....bandwidth allocation module We first present a general framework for the multicast fairness notion. Then, we enumerate some inter multicast fairness candidates functions that could be implemented by the ISPs. We consider the two existing multicast service models: the ASM (Any Source Multicast) [7] model and the SSM (Source Specific Multicast) model [13] 2.2.1.1 General framework The multicast bandwidth allocation module determines the link capacity fraction that should be allocated to the flow to which the incoming packet belongs. We develop hereafter a general framework of the ....

....intermediate routers for each active multicast session can help to resolve some of these di culties and it will be then a main key of the widespread deployment of IP multicast. Indeed, it will be possible to solve the feedback implosion problem that occurs when we deal with NACKs messages or IGMP [6] in some kind of physical link support such as satellite network. In addition, the ISPs will be able to establish a valid business model for multicast that take into account the number of group members [16] In some other protocols such as RTP [29] and SRM [14] the information of the number of ....

In the standard multicast service model [6], neither the source nor the intermediate routers can know the number of downstream receivers. Previous work on estimation of group size using probing techniques and analytic models includes [1, 3, 15, 21, 26, 27] These proposals have three main drawbacks. First, they uses tuning parameters whose ....
