An Access Network can be defined as a network of resources, shared by a geographically clustered group of a large number of non-cooperating users, that makes locally accessible to these users, the services of a global network. Public transport networks such as bus and train networks which connect residents of neighboring towns to an international airport are general examples of an access network. In the realm of data transport networks, Digital Subscriber Line (DSL), DOCSIS (cable-modem), EPONs (fiber-to-the-home), and PSTN-based dial-up networks are some particular examples of prevalent access networks. This project aims to study and design such data access networks. Our past work has dealt with access networks based on the DOCSIS and and IEEE 802.3ah (EPON) standards. We have evaluated the performance of Device Discovery and QoS schemes and surveyed and designed bandwidth allocation algorithms in such networks.

The EPON part of this project was funded in part in part by two grants from the Cisco University Research Program. The DOCSIS portion was supported by the UNH InterOperability Laboratory.
