Compressing ATM streams on-line

Περίληψη

Summary form only given. Asynchronous transfer mode (ATM) is one of the state-of-the art network protocols nowadays. A main characteristic of an ATM network is that its switches should be fairly simple and inexpensive. As a result, a significant part of the network cost is in the cost of the links. So by increasing the network traffic we can send over a given link, we will certainly increase the effectiveness of the whole network. A way of increasing this traffic is to send compressed ATM cells. This idea, although it seems very simple, is a new one and we have proved that it is very important. Our compression scheme is particularly useful in LAN since it will increase the bandwidth of a typical ATM LAN by at least 250%. This increase comes at a minimum additional cost (the cost of a pair of our inexpensive hardware chips per link) and with no bad side effects. This scheme is also useful in WAN. The effective bandwidth of such a network can be increased by about 50% at a minimum additional cost and without any side effects, again. This increase is particularly important in the case of WAN since the cost of the link bandwidth in such a network dominates by far the cost of the whole network. But the kind of networks that would be perfect for applying this compression scheme to, will be the LAN interconnection networks over WAN. In these networks the increase in the effective bandwidth of the expensive WAN links will be equal to that of a typical LAN (e.g., at least 250%), since the traffic sent over these WAN links will be mainly LAN traffic.
