This memo describes security threats for the larger (intra-domain or inter-domain) multicast routing infrastructures. Only Protocol Independent Multicast Sparse Mode (PIM-SM) is analyzed, in its three main operational modes: the traditional Any-Source Multicast (ASM) model, the source-specific multicast (SSM) model, and the ASM model enhanced by the Embedded Rendezvous Point (Embedded-RP) group...

Network management for multicast traac has become a key to the continued deployment of multicast in the Internet. The lack of usable management tools is believed to be one of the barriers to any substantial use of multicast in production Internet services. Because multicast is a relatively new service, management tools either do not exist; do not provide the right functions; or are too hard to ...

Status of This Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. Abstract This document specifies Protocol...

This document describes the Border Gateway Multicast Protocol (BGMP), a protocol for inter-domain multicast routing. BGMP builds shared trees for active multicast groups, and optionally allows receiver domains to build source-specific, inter-domain, distribution branches where needed. BGMP natively supports "source-specific multicast" (SSM). To also support "any-source multicast" (ASM), BGMP re...

In this work, we study the benefits of using application layer multicast in ad hoc networks. We propose a flexible receiver-driven overlay multicast protocol that we call the Application Layer Multicast Algorithm (ALMA). As an application layer protocol, ALMA constructs an overlay multicast tree of logical links between the group members. Our protocol has the advantages of an application layer ...

In mobile ad-hoc network, some multi -channel MAC protocols utilize multiple channels to reduce the collision of wireless transmission and thus get high throughput. These multi channel MAC protocols aim at improving the performance of unicast communication, and multicast data are generally transmitted through broadcast. So multicast can’t benefit from the multi -channel technique. This paper pr...

Traditionally, reliable multicast protocols are deterministic in nature. It is precisely this determinism that tends to become their limiting factor when aiming at reliability and scalability, particularly in highly dynamic networks, e.g., ad hoc networks. As probabilistic protocols, gossip-based multicast protocols, recently (re-)discovered in wired networks, appear to be a viable means to “fi...

Group services like the audioconference require a minimum level of quality of service for the adequate transmission of multimedia packets, and the improvement of signaling processes for the establishment, maintenance and release of multicast group sessions. Traditionally, the SIP (Session Initiation Protocol) servers have dealt with unicast signaling and complementary support IP (Internet Proto...

Whereas much of the recent thrust in IP multicast standardization has focused on multicast routing and other supplementary infrastructure for multicast, the reach to/from end-systems from/to the multicast infrastructure constitutes a significant barrier in deploying any network layer multicast protocol. A basic problem arises from the fact that current IP multicast protocols have been designed ...

A mobile ad hoc network (MANET) is a selfconfiguring infrastructure less network of mobile devices connected by wireless.A protocol manages group membership and controls the path that multicast data takes over the network. Examples of multicast routing protocols include Protocol Independent Multicast (PIM). There are lots of multicast routing protocols, some works with wired networks while the ...
