A Traffic Differentiation Method for IPv6 over ATM Networks
Authors
Abstract
At present, the number of Internet users continues to increase dramatically, accompanied by the large-scale introduction of new applications with multimedia capabilities. New users and applications are constantly demanding better performance from the Internet, if possible with some forms of quality of service (QoS) guarantees. Knowing that no single technology is able to provide such guarantees in the Internet environment ' which, by definition is a multi-technology environment ' the exploration of promising technologies capable of traffic differentiation that are applicable to parts of the Internet appears as a possible way forward.This paper addresses and explores the benefits of the Internet Protocol version 6 (IPv6) and Asynchronous Transfer Mode (ATM) integration in multimedia environments. A method for traffic differentiation in IPv6-over-ATM networks is proposed, based on the mapping of different IPv6 flows into the address resolution functions of ATM. The proposal is evaluated in terms of introduced overhead, by means of simulation studies, supported by an experimental platform and an IPv6-over-ATM simulator developed for this purpose.
