NCSR: Multicast transport of BGP for geostationary Satellite network based on Network Coding

To integrate the satellite systems into the terrestrial IP network, border gateway protocol BGP is considered as a promising candidate. Taking advantage of wireless broadcast property could significantly improve the bandwidth occupation of BGP routing transport in GEO satellite network. However, its performance would be seriously degraded when interfered with the environment. This paper proposes NCSR (Network Coding for Satellite network BGP Routing transport) which applies network coding to multicast transport of BGP in GEO satellite network. NCSR exploits the broadcasting feature and achieves reliable multicast transport of BGP over the lossy space links. Representative mechanisms in transport layer are chosen to evaluate bandwidth improvement in typical scenario of DVB-S2/RCS. Through theoretical analysis and extensive simulations, we compared NCSR with other existing proposals. Results show that NCSR can not only tolerate more packet losses, but also significantly reduce more bandwidth cost of BGP. Moreover, the benefits of NCSR increase sharply with the number of participated ground terminals and the rate of packet loss.
