A Hop-by-Hop Transport Protocol for Satellite Networks
Xiaohui Hu · Journal of Astronautics · 2010
Satellite networks have some special characteristics,such as the big propagation delay and high bit-error rate,these characteristics make TCP protocols incapable of providing satisfying service for satellite networks.The paper proposes a renovation protocol based on hop-by-hop Acknowledgment against the traditional end-to-end TCP for satellite networks,which uses ACK associated with SNACK together to ensure the end-to-end reliability.It also uses load factor to do congestion control,which fully utilize the link bandwidth.The protocol is extraordinarily suitable for satellite networks and achieves the near-optimal performance.
