ITTC Project

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.

Partner with ITTC

The Information and Telecommunication Technology Center at the University of Kansas has developed several assistance policies that enhance interactions between the Center and local, Kansas, or national companies. 

ITTC assistance includes initial free consulting (normally one to five hours). If additional support is needed, ITTC will offer one of the following approaches: 

Sponsored Research Agreement

Individuals and organizations can enter into agreements with KUCR/ITTC and provide funds for sponsored research to be performed at ITTC with the assistance of faculty, staff and students.

Licensing and Royalty/Equity Agreement

An ITTC goal is the development of investment-grade technologies for transfer to, and marketing by, local, Kansas, and national businesses. To enhance this process, the Center has developed flexible policies that allow for licensing, royalty, and equity arrangements to meet both the needs of ITTC and the company.

Commercialization Development

Companies with a technology need that can be satisfied with ITTC's resources can look to us for assistance. We can develop a relationship with interested partners that will provide for the development of a technology suited for commercialization.

ITTC Resource Access

ITTC resources, including computers and software systems, may be made available to Kansas companies in accordance with the Center's mission and applicable Regents and University policies.
