High latency network is increasingly important in today's telecommunication world. It is widely used for real-time interactive multimedia applications such as video, music, data and graphic files exchange. One example of this network is the satellite communication technology. Unfortunately, the high latency satellite network provides limited network bandwidth and introduces high network latency issues. Network congestion and late packet delivery problems have posted serious threats to the network performance, especially when the bandwidth is shared among multiple concurrent users. These issues have created some negative impacts on the Quality-of-Service (QoS) of real-time applications and also user experiences. In this paper, a real-time compression scheme is proposed to improve the performance of high latency networks with limited bandwidth. The aim of this scheme is to reduce the network packet overhead by eliminating redundancies in the packet to achieve reduction in packet size and hence, increasing the effective bandwidth usage and allowing more packets to be transmitted over the link at any one time.
