PNNI Simulator: Performance Evaluation Studies and Continued Development

Project Award Date: 05-16-2001



Description

This project is a continuation of a current Sprint-funded project, of which the initial development phase of the PNNI (Private Network-Network Interface) simulator is now complete. One focus of this projects continued work is in finding the full value of the simulator, which has yet to be demonstrated through its use in more extensive performance evaluation studies. A second focus is the continued development of the simulator capabilities, as new features or modifications are required by the needs of specific experiments of interest to Sprint.

The network performance evaluations will explore the effects of numerous PNNI issues. One topic of particular interest is the effect of network topology on various aspects of PNNI signaling performance. The desired scheme is to compare the implications of an edge-core and a cluster topology with the primary performance metrics being call success rate, average call setup time, the average database size in each node, convergence time, and link utilization.

Although the major developments of the KU PNNI simulator is complete, as with all software development projects, some level of further progress in several categories is inevitable. The different categories of development are motivated by several types of issues, including correction of mistakes, extension of PNNI simplifications, increased ease and efficiency of use, creation of new capabilities (which may include optimization of PTSE flooding in the PNNI hierarchy, modification of the CAC algorithm, peer-group leader election, RCC channel implementation modifications, signaling congestion control, and signaling call processing priority).

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.
