Bursty Traffic by a PEP in an IP Network Using a Satellite Link and Its Mitigation Scheme

This paper investigates a TCP proxy, called a PEP, which splits a TCP connection to employ a specially tailored TCP connection over a satellite link. This paper describes how large size data is forwarded inside the PEP when a packet loss occurs on the satellite link. It also identifies a problem that the output traffic from the PEP becomes bursty due to the large size forward data. To mitigate bursts of packets by the PEP this paper proposes a scheme that the PEP performs a shaping function which places a gap between two consecutive segments sent by the PEP. Simulation results using ns-2 show that bursty packets are issued by the conventional PEP and the shaping function suppresses them effectively
