Vinod Vokkarane and Collaborator Awarded NSF Grant on Optical Networks

Assistant Professor Vinod Vokkarane of the Computer and Information Science Department and his collaborator from the University of Texas at Dallas, Professor Jason Jue, have been awarded a $440,000. grant by NSF. This is a 3 year grant commencing on September 1, 2006. The project title is: Service-Oriented Optical Networks (SOON) and Dr. Vokkarane's estimated total award amount is $204,488.

Dr. Vokkarane joined the UMass Dartmouth Faculty in September of 2004. His research involves "development of scaleable and reliable architectures for the next-generation of Internet using optical networks." The project website is:


*Many emerging next-generation Internet applications, such as
videoconferencing, multimedia distribution, and high-performance
scientific computing, are characterized by high bandwidth requirements,
multi-source and multi-destination communication paradigms, strict
quality of service (QoS) requirements with respect to delay and loss,
and high reliability and survivability requirements. In order to support
these diverse requirements, emerging networks must be able to manage
resources in a flexible manner. This project investigates a
service-oriented optical network architecture that is enabled by an
underlying optical transport network capable of dynamic and agile
resource allocation. An optical transport layer provides the basic
mechanisms for reserving resources, and an optical service layer builds
a set of services over the basic optical transport layer.

In the project, specific problems to be addressed include 1)
investigating mechanisms for supporting manycast communication services
in optical networks, 2) investigating mechanisms for providing
survivability in such networks, and 3) developing methods for supporting
reliable transport in optical networks. The proposed activity will
result in a framework and an architecture for deploying a wide range of
services in optical networks in order to support the requirements of the
most demanding next-generation applications. The project will also
result in the development of new algorithms and protocols for
implementing manycasting and providing reliable services, and will lead
to the development of analytical models for evaluating these algorithms
and protocols.

The broader impact of the proposed activity is that it will provide
valuable training for graduate students, preparing them for careers in
research and engineering in the field of optical networking.
