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...

In this paper we describe usage of FreeBSD operating system for IPv6 Multicast routing platform in SOI-Asia Project. SOI-Asia project is platform to deliver realtime lecture via UniDirectional Link of satellite to several countries in Asia. Because of limited bandwidth in satellite, we use IPv6 multicast to deliver material of lecture and realtime video and audio lecture. We also describe human...

This paper presents a number of experimental findings regarding the efficiency of terrestrial protocols when they are used over a satellite link at data rates of about 1.5 Mbits/sec. In particular, we present measurements on TCP/IP and a theoretical model which explains the observed performance and points towards possible ways in which this protocol stack can be used more efficiently on a satel...

This paper presents an overview of possible interference mitigation techniques aiming at increasing the system capacity of broadband multimedia satellite systems. A multi-star network topology using a bent-pipe transparent satellite is assumed. After a general overview, the paper concentrates on the assessment of Linear Precoding techniques for increasing the potential system capacity on the Fo...

It has already been confirmed that the traffic in high-speed terrestrial network presents self-similarity, but there is little research on self-similarity of traffic in satellite network. Considering time-varying network topology and link status, this paper analyzes the aggregation and propagation of self-similar traffic between nodes in satellite network. Furthermore, a sort of special network...

Tbis paper describes a global environmental data distribution systeD (GEDDS) wbich uses a siogle sDall satellite operating in a low polar orbit. The satellite collects envirollllental data frolll remotely located instru:aentation platforms and distributes it to research laboratories and other interested organizations virtually anywhere in the world. A command link also allows principal investig...

We describe many issues with TCP over satellite performance in relation to two scenarios: hybrid and backbone. We examine what e ect having a backbone of 255ms (satellite link) has as opposed to having just a 70ms delay. We explore, through simulation, the e ect of Tahoe, Reno and SACK TCP on this performance, in the context not just of droptail queueing but also varying settings of the paramet...

Designing efficient transmission mechanisms for advanced satellite networks is a demanding task, requiring the definition and the implementation of protocols and architectures well suited to this challenging environment. In particular, transport protocols performance over satellite networks is impaired by the characteristics of the satellite radio link, specifically by the long propagation dela...

| We examine the design of a communication link involving the data transfer from a small, low-orbit satellite to a ground station, but through a geostationary satellite. The advantage of this approach is that a single ground station , which tracks only the geostationary satellite, may be shared by a multiplicity of small satellites. Our goal is to select certain small satellite parameters { sig...
