PROJECT SUMMARY
Proposal Number:
Project Title:
A NEW APPROACH FOR VIDEO MULTICAST ON WIDE AREA NETWORKS
Technical Abstract:
This SBIR Phase I effort proposes an approach for extending the Internet
infrastructure to support real-time, video transport. This extension
addresses the need for wide area network (WAN) based collaborative
environments for efficiently sharing information as well as the growing
requirement for telepresence and telecommuting.
Our approach for video multicast over wide area networks is unique in that it
does not require the network to reserve link bandwidth on each link associated
with the path of a video flow. This is in contrast to existing approaches that
impose resource reservation requirements on every link of a path. The
flexibility provided by our approach allows it to accommodate a more
heterogeneous network that existing approaches. The proposed approach for
video multicast is based on an innovative technique for video packetizing and
traffic control called spectral selection.
The objective of this Phase I SBIR effort is to establish the feasibility of
proposed approach for video multicast. To achieve this goal, this effort will
develop the design of the network software required to implement the proposed
video multicast approach and assess the performance of the approach using a
combination of analytical and simulation techniques.
Potential Commercial Applications:
The commercial application of the results of this research would be network
software that would allow the Internet to accommodate video-enabled
applications such as telepresence, multimedia-conferencing, remote learning,
visualization and computer supported collaborative work on a more
heterogeneous wide area platform than is currently possible. It would thereby
extend the capability of the NII to serve various sectors of the national
economy ranging from health care to manufacturing and distance learning.
