Data Dissemination Group
Welcome to the Data Dissemination Group site at the Brown Computer Science Department.
Here is a list of our current projects :
Publish-Subscribe Simulation: We
are building a network simulator to investigate publish-subscribe systems.
Some of the issues being studied are data scheduling, bandwidth allocation,
channelization, client profiling, etc.
DBIS Toolkit: The DBIS(Dissemination Based
Information System) prototype toolkit is a set of modules which can be
used to build-up a heterogenous distributed client-server network supporting
different modes of data transfer. ie. unicast, multicast, broadcast, push,
BADD: We are part of a network of universities
and companies working on the BADD project, which
involves building a satellite data dissemination system for the US armed
Broadcast Disks: The Broadcast Disks project looks into client-server systems from a push perspective. Some of the issues studied are cache management, organization of data on the broadcast, effect of updates on the system, prefetching techniques, etc.
