Research on Gigabit Gateways: Access to Future Public Switched Networks

Project Award Date: 1992


Gateways between local area, high speed connectionless (CL) networks and connection oriented (CO) wide area B-ISDN do not exist today. This research is focusing on advancing the state of the art in gateways that connect high speed CL premises equipment and long distance CO networks.

A 622 Mbps (OC-12 SONET) gateway is being designed and implemented to interconnect experimental DEC AN2 Gigabit LAN switches at the University of Kansas with the MAGIC testbed. All required hardware and software for the gateway will be developed and integrated into the testbed. We are addressing issues related to the control of high capacity LANs and B-ISDN networks as well as signaling, protocol integration, protocol internetworking, and multiple protocol environments. New dynamic mechanisms to control and manage high speed CL to CO connections are being developed and incorporated into this gateway. Implementation of these mechanisms will require that issues related to the effects of network propagation delay (latency) on dynamic network control, provisioning of bandwidth-on-demand services, premises-to-premises capacity assignment, and real time estimation of available network capacity be addressed. When ATM switching equipment is added in MAGIC, the interworking of the AN2 Gigabit LAN with an ATM Switch will be achieved. The testbed will then provide an environment for research on B-ISDN signaling among customer premises equipment, access interfaces, and the Gigabit network. Experiments will be conducted using the developed gateway to research the capabilities of Gigabit LAN/WAN systems. Gateway experiments will be focused on two issues: distributed interaction with the specific MAGIC terrain visualization application and high speed networking in a heterogeneous environment. Traffic characterizations will be developed based on measurements from the network.


Project Sponsors

Primary Sponsor(s): ARPA, Digital, Sprint, Northern Telecom/BNR, Southwestern Bell, Kansas Technology Enterprise Corporation

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.
