Popis: | High speed cable/ADSL connections are rapidly becoming the standard for Internet at home. Conversely, mobile network operators only offer low bit rate data services to their 2.5G users, and 3G only starts to be deployed. In this context, the cooperation between a mobile telecommunication network and a broadcast network can be a suitable alternative to enhance this offer with high speed e-mail, web browsing, file download. This paper presents a network architecture based on the coupling of a GPRS up-link with a DVB-T down-link, to provide Internet connectivity for unicast and multicast services. We first study the asymmetric network and show the issues raised by the return channel. After description and comparison between two network architectures, one with TCP and the other with SCTP protocol, we analyze, using simulations, how to modify the SCTP protocol to increase the GPRS/DVB-T hybrid network performances. Finally, we describe simulation model of network architecture, and evaluate its performances. I. INTRODUCTION This work is placed in a global context of cooperation between several networks. At the beginning, TCP protocol was conceived for reliable transport of data on wired networks. In a context of cooperation between wireless, heterogeneous, and asymmetrical networks, TCP can prove to be a limitation for performances of the system (10). Several studies have proposed to modify the TCP congestion control algorithm in order to improve performances. Nevertheless, in this architec- ture none of TCP solutions offers significant improvements. Investigations led us to propose a new protocol architecture based on SCTP as protocol for transport layer. In this ap- proach, we are to endeavor to limit the modifications of SCTP (2), exclusively in the receiver side. Somme TCP variants have been proposed to solve this issue, however all proposals need modifications on Internet routers or on the two peers of communication, or use static mechanisms. To ensure a real deployment, there is no modification in the server side, nor in Internet routers, but only adaptations in the client side. |
