This paper describes the issues that arise when using satellites for IP multicast, with the emphasis on multicast protocols and how their implementation depends on the satellite communications platform.Various link layer standards such as DVB-S, DVB-RCS and ATM can be used in satellites with onboard processing, and applied to meet user and network requirements for IP multicast. The paper provides an overview of the networking issues and their interactions. Specifically, we show how multicast networking protocols have to be modified to take into account the satellite link characteristics: these protocols include IGMP, multicast routing protocols and reliable multicast protocols. We also discuss how security systems support IP multicast.KEYWORDS: satellite, multicast, security, Internet, IP, QoS, DVB, ATM, IGMP INTRODUCTIONIn recent years, much research and development has been carried out in satellite networking technologies and applications. Some network technologies that have received significant attention for broadband services are ATM over satellite, Digital Video Broadcasting -Satellite (DVB-S) and DVB Interactive Return Channel via Satellite (DVB-RCS), together with IP for Internet access and interconnection. In terms of applications, the work has focused not only on traditional best-effort services such as file transfer and world-wide web applications, but also on support for real-time multimedia and multicast applications with specific quality of service (QoS) requirements. The success of satellite digital broadcast services (for TV and radio) and the asymmetric nature of IP traffic flow have been combined to result in satellite systems that support high-speed Internet access.

“…• the foreign network the source is visiting might not contain a multicast router; thus, a packet sent to a multicast channel is dropped; • if the source uses its home address as the source address of its packets, ingress filtering routers [19] drop them because of security considerations; • the first router that receives a packet might not be connected to the original tree; thus, it does not have state for the channel, and drops the packet; • most routing protocols perform an RPF (Reverse Path Forwarding) check [20]; if the mobile source uses its home address to send data, packets are dropped.…”

“…First, we use a protocol to construct a multicast forwarding tree connecting sources and receivers in a multicast group. Currently, Protocol Independent MulticastSparse Mode (PIM-SM) [21] is the most widely used protocol for multicast tree construction in the Internet. In addition, in order to provide inter-domain multicast service, we use Multiprotocol Border Gateway Protocol (MBGP) [22] to communicate multicast path availability and Multicast Source Discovery Protocol (MSDP) [23] to communicate multicast source availability among different domains in the network.…”

Abstract-Monitoring and management have become key requirements for the success of multicast deployment in the Internet. One of the most important monitoring tasks for multicast is to verify the availability of service in the network. This task is usually referred to as reachability monitoring. In this paper, we present an application layer multicast reachability monitoring system called sdr-monitor. Sdrmonitor has emerged in response to the practical need of verifying service availability and detecting potential problems during the early years of native multicast deployment in the inter-domain. Sdr-monitor leverages an existing application and provides close to real-time reachability monitoring for the multicast infrastructure. Since its initial deployment in 1998, sdr-monitor has been serving the multicast community in detecting and correcting multicast reachability problems in the Internet. In addition, sdr-monitor pioneered a number of additional research projects in multicast monitoring and management. In this paper, we first present the architecture of the sdr-monitor system and its outputs. Then, by using a four-year reachability monitoring data set, we present a long term analysis of the reachability characteristics of the multicast infrastructure. Next, by using additional network layer information, we classify reachability problems. Finally, we evaluate sdr-monitor as a reachability monitoring system and identify a number of ways in which it could be improved.
