Performance evaluation of an adaptive ring access protocol for super high-speed networks

Abstract

As the number of World Wide Web (WWW) users have been growing, the network traffic over the Internet have increased. As a result the Internet has been suffering from a chronic congestion. To improve this situation, it is necessary to develop a super high-speed backbone network. We propose a media access protocol for super high-speed backbone networks such as terabit networks. The cost of network facilities for terabit networks is high. Therefore, we consider a shared media network such as a ring topology in order to decrease the network cost. Our goal is to build an adaptive protocol with high throughput and good fairness. To achieve this, our protocol considers the traffic condition on the ring. If the traffic on the ring is low each station can send a lot of packets. Otherwise, when the ring starts to become congested, the number of packets sent by stations starts to decrease. Performance evaluation via simulations shows that proposed protocol has a good behavior and can be used as a backbone network for high-speed networks.
