Performance analysis and comparison of ptop and lane for IP transmission over atm network

摘要

Due to its traffic control and performance assurance characteristics, ATM is being employed as the core network in most campuses. However, bulk of the workstations remain on Ethernet, generating IP traffic that passes through ATM using special schemes such as PTOP or LANE. In such a network, the performance is affected due to the extra overheads in multiple conversions between cells and packets and managing virtual circuits. The aim of this paper is to compare the performance of PTOP and LANE in passing the IP traffic under various condition. This study helps in understanding the various performance issues in these environment in order to define the end-to-end quality of service for Ethernet-ATM networks.
