ITTC Project


Development Multilink PPP Technologies from Iridium

Project Award Date: 08-28-2003



Description

We have a requirement for communications to polar regions as part of our Polar Radar for Ice Sheet Measurements (PRISM) project. Communication coverage in Greenland and Antarctica must be truly mobile, and its implementation requires relatively inexpensive equipment. To support these requirements, we have selected to use Multilink point-to-point protocol (MLPPP) over the Iridium satellite system. This method involves splitting data (IF) packets into smaller fragments, transmitting each fragment over different links and recombining them at the receiving end. Thus, we obtain an effective bandwidth, which is approximately the sum of the bandwidths of a1l links. We have implemented MLPPP on Linux and have recently conducted field experiments in Greenland to measure the reliability, throughput, and general performance of this system. While the detailed performance data are still being analyzed, it was clear that the system met our expectations for performance. This system has the potential to support the requirements for remote communications for a defense contractor.

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.
