In this paper we present the design, implementation, and performance analysis of Group-Aided Multicast (GAM), a scalable many-tomany reliable multicast transport protocol. GAM achieves high quality ACK trees while keeping the tree maintenance overhead reasonably low in the presence of dynamic group membership and route changes. It is supported by a group configuration mechanism organizing the m...

This document describes best current practices for intra-domain and inter-domain deployment of the Multicast Source Discovery Protocol (MSDP) in conjunction with Protocol Independent Multicast Sparse Mode (PIM-SM).

This paper describes Root Administered Multicast Addressing (RAMA), a protocol for wide-area IP multicast that scales to a large number of simultaneous groups with topologically distant members. RAMA solves the widearea “rendezvous” problem by making the root of the distribution tree explicit in the multicast group identifier. This is done by extending the 4-byte IPv4 multicast group address fo...

Many applications, such as broadcasting stock quotes and video-conferencing require data source authentication of the received multicast traffic. Multicast data source authentication must take into consideration the scalability and the efficiency of the underlying cryptographic schemes and mechanisms, because multicast groups can be very large and the exchanged data are likely to be important i...

In this paper we present the design and implementation of a novel protocol solution for distributing high quality compressed video streams to multiple receivers across a network. Our end-to-end protocol uses the connection-oriented multicast facility in the next-generation transport, the Xpress Transfer Protocol (XTP). XTP multicast provides in-order, multipoint delivery of packet streams with ...

With IP Multicast not gaining wide acceptance, researchers turned to alternative multicast mechanisms like application level multicast. Application Level Multicast protocols arrange the participating hosts into an overlay topology; maintain it and distribute data packets over that topology. In this paper, we propose a new application level multicast protocol, describe few well-known protocols, ...

In this paper we propose a new protocol for reliable multicast in a multi-hop mobile radio network. The protocol is reliable, i.e., it guarantees message delivery to all multicast nodes even when the topology of the network changes during multicasting. The proposed protocol uses a core based shared tree. The multicast tree may get fragmented due to node movements. A notion of forwarding region ...

Using multicast communication in Wireless Sensor Networks (WSNs) is an efficient way to disseminate code updates to multiple sensor nodes. For this purpose a multicast protocol has to support bulky traffic (typical traffic pattern for code updates) and end-to-end reliability. In addition, we are interested in energy-efficient operations due to the limited resources of WSNs. Currently no data di...

In this paper, we show that substantial improvement in multicast performance and reliability can be achieved by regarding a multicast group as a network region and using anycast to access it along the shortest path. We introduce the anycast-based tree (ABT), a novel architecture for building efficient shared multicast trees. ABT is a noncore tree; thus, it does not suffer from the traditional p...
