Can network coding bridge the digital divide in the Pacific?

摘要

Conventional TCP performance is significantly impaired under long latencyand/or constrained bandwidth. While small Pacific Island states on satellitelinks experience this in the extreme, small populations and remoteness oftenrule out submarine fibre connections and their communities struggle to reap thebenefits of the Internet. Network-coded TCP (TCP/NC) can increase goodput underhigh latency and packet loss, but has not been used to tunnel conventional TCPand UDP across satellite links before. We report on a feasibility study aimedat determining expected goodput gain across such TCP/NC tunnels into islandtargets on geostationary and medium earth orbit satellite links.
