In satellite-based networks, current TCP Protocols have lower throughput performance mainly due to the effect of long propagation delays and high link error rates. In this paper, a new congestion control protocol for satellite-based networks is proposed. The protocol uses a proactive approach and is composed of novel ideas like Proactive Slow Start, Proactive Congestion Avoidance and Decision based Error handling policies that are combined with traditional TCP algorithms, like Fast Retransmit. The mainstay of the authors' protocol is the nature of the RTT pattern can give them indication of an incipient congestion in the network.
