Determination of the Impact of Advanced Traffic Controls on the Performance of Edge/Core ATM Network Architectures
Project Award Date: 1998
Understanding the customer perceived performance as high speed networks rapidly evolve is critical to success of service providers. Using analysis, simulation, and measurements on the MAGIC and AAI system, we have come to comprehend the performance implications of the first generation of ATM products and networks. This proposal addresses the next challenges; i.e., to consider the issues related to the variety and interactions of Available Bite Rate (ABR) control algorithms, implications of Virtual Source/Virtual Destination (VS/VD) architechtures, and interactions between TCP/IP, ABR Quality of Service (QoS) guarantees provided by policing traffic flows.
We will approach obtaining an understanding of these issues using the tools we have successfully developed and applied to the first generation of ATM networks: algorithmic analysis, simulation, and measurements on prototype networks, specifically using the KU/TIOC facilities, MAGIC, AAI, and SPARTAN.
It is significant to note that these facilities will allow us to evaluate the impact of hosts connected over a range of link capabilities, from low speed wireless to 622 Mb/s (OC-12c).
The results of this effort will enable the deployment of an efficient long distance ATM network that meets customer expectations for functionality and quality of service.
