A link-state routing protocol for the provisioning of data services over ATM networks

Traditional link-state routing protocols are able to support data services over ATM networks, and are the basis of some recent networking solutions. F rom the network providers' point of view, the use of these routing protocol s represents an important cost saving, because they are well known and wide ly used in the Internet. However, these protocols need to be improved to de al with traffic variations. The aim of the routing proposal described in th is paper under the name of Dynamic-Metric and Metric-Range (DM-MR) routing is to provide these traditional routing schemes with mechanisms for adaptat ion to network load conditions. The proposal comprises mechanisms for evalu ating the traffic load and mechanisms for updating the routing information accordingly. It includes also a path selection strategy that reflects the t raffic load condition. (C) 2001 Elsevier Science B.V. All rights reserved.
