Aircraft Data Networks and Performance Enhancement Proxies

With the increased deployment of data networks within the aircrafts, it is important to find ways to provide better service to user traffic. In order to provide Internet services within the aircraft, it is important to use the services of satellite networks. Satellite networks introduce high amount of delay in the data transfer process. Internet traffic based on transport control protocol (TCP) suffers due to the high delay introduced by the satellite network. Performance enhancement proxies have proved to be beneficial in the satellite network environment when Internet traffic was transported over the satellite network. In this paper, the authors investigate the advantages of using performance enhancement proxies in the aircraft data network environment
