ITTC Project

Traffic Mangagement and Controls for ATM Networks

Project Award Date: 0000-00-00


Component 1: Integration and Evaluation of CBR/VBR/ABR Controls with Voice/Data/Video/Image Traffic

There have been several traffic controls proposed and studied for CBR,VBR and ABR services. Some of these would function within customer equipment, some at the ATM access point (or User-Network Interface-UNI), and others would be distributed throughout the ATM Network. This component will focus on UNI and network-distributed controls, and only those that are applicable once a connection has been established.

Component 2: Development and Evaluation of Dynamic Renegotitation of Traffic Contract

Recent traffic measurements indicate that a connection may have traffic requirements that vary significantly with time, even when the time scale is large (tens of seconds, minutes, or even hours). If the traffic contract is static, the connection user must estimate the most demanding values for the traffic contract parameters that would be expected over the duration of the connection. This would be not only difficult but also wasteful of network resources. ITTC plans to develop a complete dynamic traffic contract renegotiation system and evaluate its performance.

Component 3: Modeling and Evaluation of a Global Network Management Overlay for Call Admission Control (CAC) and Network Resource Management

A major unknown in network resource management is the uncertainty about what information is needed by the "resource allocator" and how often this information should be collected. ITTC's approach will be to structure simulation-based experiments to determine the sensitivity relationships between control parameters: e.g., the CAC policy on a VP, and the QoS.

Component 4: Real-Time Experimental Evaluation of ATM Network Controls With Multimedia Connections

ITTC will evaluate the feasibility of implementing varios traffic controls within a real-time control and measurement framework, choose a set of controls to implement, design experiments to evaluate the performance of these controls with multimedia connections, perform the experiments, and analyze the results.

Component 5: Evaluation of Service Aspects, Controls, and Signaling for Network Interfaces (BICI/NNI)

This component will provide a careful evaluation of the service aspects, controls, and signaling for interfaces between network service providers.

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.
