Expected Outputs

A Multipoint Communication System with VSAT
Multicast Applications Using Satellite Communication

Topics

In order to carry out multicast communications on the Internet efficiently, a general Multicast Satellite Communication Architecture using VSAT Satellite Station has been designed and multicast protocol and applications have been implemented. In addition, an internet architecture utilizing the satellite's mobility, geographical universality, and dynamic route configuration was established and applied tothe actual Internet, thus allowing communication not possible on former network architectures.

Schedule

End of July '96: Establish tunneling and a virtual gateway using the VSAT Satellite and investigate its possibility as an alternative route on the WIDE Internet
End of March '97: Create multicast applications which will run on the new architecture
