Active Router for Bandwidth Bargain Model

Prepared by:  Lijun Wang, M. Sc. candidate

There is an increasing growth of need that application service providers can offer differentiated service levels for a variety of services on the Internet, for example, live video broadcasting, remote medical diagnosis, IP telephony, etc. Among the real implementation of those services, one of the most important issues is how to handle the network resource allocation efficiently. In this project, based on the concept of active network, we design the architecture and desired functionality of an active router used for proposed Bandwidth Bargain Model. This active router will be able to dynamically assign network bandwidth to various packet flows, according to the service level agreement and current bandwidth request from different applications. The features of a bargain protocol will be developed and the possible schemes of bandwidth granularity will be studied.

     Due to the availability of OPNET, which is a powerful network modeling and simulation environment, we do not need to design the router from scratch. We are going to do the implementation and simulation of our design using OPNET, and focus on the specific behavior of our model, without caring about the basic router functionality that has been already handled by OPNET successfully.
