ITTC Project


SGER: System-Level Network Modeling

Project Award Date: 09-01-2003



Description

Modern communication networks are shifting from providing a basic data transport capability to providing a rich collection of network services. Recent advanced services envisioned by network designers include: multicast, reliable and adaptive multicast, resource reservation, caching services, and mobile access. Even these services and capabilities are eclipsed by needs for network protection, distributed web-page composition, repelling denial of service attacks, and assured network communications. The underlying network structure used to deliver these services is rapidly changing, becoming increasingly mobile and dynamic. We are embracing more wireless infrastructure, more mobile computing devices, increased interaction between services, and increased dynamic network services. To achieve desired capabilities in the increasingly dynamic network environment, dramatic changes in networking infrastructure are being introduced to provide a rich and highly dynamic networking environment. Yet, to the user, the network must be consistent and predictable. These changes pose new challenges in the way network systems and services are designed and deployed.

We will explore new techniques for design of advanced networking services. Specifically, we will concentrate on understanding and predicting emergent behaviors resulting from interactions between and among services and infrastructure elements. Our hypothesis is that using new, rigorous system-level design techniques, network infrastructure can be more flexible while at the same time provide more predictable network services. We propose using formal techniques to define and analyze network services, network infrastructure, and interactions between desired services and available infrastructure. The net result will be techniques for predicting the behavior of interacting network services implemented on a heterogeneous, dynamic network infrastructure.

The proposed research activity brings together ongoing research in network design, formal methods, and systems-level design. The fundamental intellectual challenge is the identification of appropriate representations and analysis techniques for network systems within the systems engineering and formal methods domains. The greatest challenge within that task, scaling techniques to the systems level, remains a difficult, unsolved problem. This project will provide sufficient justification for a long- term research program addressing this problem.

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.
