Compressing Packets Adaptively Inside Networks

Introducing adaptive online data compression at network-internal nodes is considered to mitigate congestion on the network. In this paper, assuming that advanced relay nodes, which possess both a relay function (network resource) and a processing function (computational and storage resources), are placed inside the network, we propose an adaptive online lossless packet compression scheme performed at these nodes. This scheme selectively compresses a packet according to the waiting time of the packet in the queue during the congestion period. Through computer simulations, we show that our proposed scheme reduces the packet delay and discard rate and investigate the key factors necessary in achieving an efficient packet relay.
