Ip Multicast over Satellite
نویسندگان
چکیده
Satellites have been very successful for digital broadcast, and it is a natural step to develop IP multicast over satellite to explore the potential of the satellite systems. This paper discusses the issues of IP multicast over satellite, based on IP multicast protocols using different satellite communications systems including DVB-S and DVB-RCS. The paper provides an overview of the networking issues and their interactions. The work is based on the studies of the European IST GEOCAST project within the IST’s 5th Framework programme. The paper explains how IP multicast protocols can be implemented over satellite links, looking particularly at the issues involved in implementing IGMP, multicast routing protocols reliable multicast protocols, and security.

QoS for real-time multicast over satellites
Next generation satellite systems are ideally suited for multicast and real-time traffic. Therefore, it is highly attractive to offer IP multi-videoconference services over IP multicast enabled satellite systems, combining link efficiency and access to remote areas. ICEBERGS project, presented in this paper, addresses the integration of IP video and IP multicast in EuroSkyWay geostationary sate...
متن کاملNetworking issues in IP multicast over satellite
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 provi...

The aim of the MECCANO project was to provide a robust networked multimedia education and conferencing environment, suitable for use over a wide range of network technologies. To cope with the heterogeneity this implies, the Internet Protocol (IP) was adopted as a unifying platform over a range of layer 2 technologies (Ethernet, ATM, direct broadcast satellite, ISDN). Where it is not possible t...
متن کاملIssues on the IP Multicast Service Behaviour over the Next-Generation Satellite-Terrestrial Hybrid Networks
Our main focus here is to study the IP multicast service behaviour over the next-generation of satellite-terrestrial hybrid networks for which we develop a general architecture and we enumerate their main characteristics. We first focus on the IGMP feedback implosion problem and we present the exponential feedback raise that able to provide sufficiently stable expectation values across a large ...
