Scalable Performance Models for Large Scale Networks with Correlated Traffic

Project Award Date: 08-16-2001


Markovian models that capture the effects of network traffic, exhibiting long-range dependent characteristics or correlations over many different time scales, frequently suffer from the problem of not being scalable to large systems. The goal of this research is to build powerful, efficient, and scalable models that capture network behavior for varying levels of abstraction and varying finite time scales while incorporating long-range dependence and heavy tails. This entails the development of network models that can be employed at several layers of abstraction, which will allow for a full understanding of network behavior, and will use near-decomposable techniques for state reduction and time scale resolution. These models will not solely rely on steady state results, but rather on a finite horizon that would allow for online monitoring and early detection of rare events.

This project aims to study high-speed access networks, as these types of networks have been shown to have highly correlated and bursty traffic. We hope to demonstrate applications of our methods to packet level analysis of congestion control strategies over a finite window of operations; including various packet discard policies, rate and credit flow control, and random early detection protocols under realistic traffic conditions.

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.
