The Stream Control Transmission Protocol (SCTP) has recently been standardized as a new transport layer protocol in the IP protocol suite. In addition to the core features of TCP, SCTP incorporates a number of advanced and unique features which are not available in TCP. The objective of this paper is to investigate the suitability of SCTP for data communications over satellite links. We describ...

A number of broadband satellite systems have been proposed in recent years offering alternative technical solutions. The highest possible level of commonality is desirable especially for user terminals, even when different satellite transmission systems are used, in order to reduce the cost of user equipment and expand the satellite services market. IP-based transport is increasingly seen as a ...

We investigate the efficient handling of TCP/IP based applications over the GEO satellite segment of the Global Mobile Broadband System (GMBS), namely the EuroSkyWay (ESW) satellite network. We first briefly, summarize the state-of-the art of TCP protocol support over GEO satellite networks; then, we propose a novel approach, based on a “hybrid” inter-working protocol, named IWL-TCP, which oper...

The standardization of a Return Channel via Satellite and the satellite community efforts in term of interoperability over the last few years stands for major milestones in the development of reliable, efficient and low cost satellite equipments. It leads to quite a positive outcome: geostationary satellite networks are expected to play a decisive role in bridging the existing digital divide th...

Telecommunication networks of the future are believed to involve systems that will work on different technologies, such as WiFi, WiMAX, 2G/3G, LTE, and satellite. In order to efficiently orchestrate the working of the different technologies, the idea of hybrid networks is being seriously considered. The chief driving factor is to facilitate and then exploit the cooperation of different wireless...

The reliable design of a satellite communications network, operating at Ku band and above, requires the exact evaluation of the interference effects on the availability and performance of both the uplink and downlink. In this paper, the case of Uplink Adjacent Satellite Network Interference is examined. We accurately calculate the deterioration of the uplink clear sky nominal adjacent satellite...

In this document we describe the architecture of BRAHMS (Broadband Access for High speed Multimedia via Satellite), project sponsored by EU in the framework of IST research programme. BRAHMS aims at specifying an IP-based architecture for broadband satellite access independently of the particular GEO or LEO satellite technology adopted in the satellite link. Broadband Multimedia Satellite Syste...

Geostationary satellite networks are currently considered as one of the most promising broadband access network technology for narrowing the digital divide. Though technically attractive and cost effective, the provisioning of endto-end QoS services in satellite access remains largely undefined. In order to bridge this gap, the European SATIP6 project defines a complete QoS architecture involvi...
