TCP-DERWOOD: A TCP Variant to Address Link Switches

Switching between Line Of Sight (LOS) links and satellite links in an Airborne Network (AN) environment causes many challenging problems for the transport protocol. The typical bandwidth of a satellite link may be in the order of 1 Mbps and the Round Trip Time (RTT) may be around 500 ms. The bandwidth of a LOS link is in the order of 300 Kbps and the RTT is just a few milliseconds. Therefore, switching between these links can cause significant changes in both the capacity and the RTT. Most current TCP variants perform poorly under such network dynamics.
