Quality-of-Service (QoS) in Heterogeneous Networks: CLIP, LANE, and MPOA Performance Test

Abstract

Interoperability is a most challenging issue in today’s network infrastructures. Especially ATM and IP have to be ever more adaptive and integrative with each other. Additionally, the issue of QoS has not been adequately addressed in today’s available heterogeneous platforms. This paper will be discussing the interoperability of different technologies such as the Internet Protocol (IP) and the Asynchronous Transfer Mode (ATM) in a heterogeneous environment, because they are considered the most important protocols in the near future. Furthermore, this paper will be discussing Classical IP (CLIP), LAN Emulation (LANE) and Multiprotocol-over-ATM (MPOA) solutions concerning the adaptation and integration of IP and ATM and their performance. As a manufacturer-independent company, the WWL Internet AG (WWL) tested different already available solutions of different manufactures and compared the results. WWL regularly evaluates new technologies for ones own better understanding and in order to build up special knowledge to support qualified customers. Following there will be, furthermore, discussed the effectiveness of the integration of IP and ATM and this will be accompanied by test results.
