Optimisation of SIP session setup for VoIP over DVB-RCS satellite networks

Abstract: With the proliferation of the internet, voice over IP has penetrated in both terrestrial and satellite networks. One of the popular protocols responsible for its widespread usage is SIP. SIP is the signalling protocol responsible for the session establishment and termination. By default, it uses UDP as the transport layer protocol. As UDP is an unreliable protocol, the retransmission ...

A QoS Architecture for DVB-RCS Next Generation Satellite Networks

The standardization of a Return Channel via Satellite (DVB-RCS) and satellite community efforts in term of interoperability over the last few years lead to quite a positive outcome: Geostationary satellite networks are intended to provide broadband access to interactive multimedia services in low infrastructure areas. However, in order to take in account real-time multimedia traffic, an efficie...

PLATINE: DVB-S/RCS Testbed for Next Generation Satellite Networks

Evaluating performances over real data links or network is often costly, even impossible for systems in development phase. In such situation, emulation is the key to provide a low cost and demonstrative platform. The main problem is to overcome the emulation weakness which is the accuracy of the model reproducing the systems to be evaluated. Owing to its modular design and implementation, the P...
