The engineers who analyze tra c on high bandwidth networks must lter and aggregate either recorded traces of network packets or live tra c from the network itself. These engineers perform operations similar to database queries, but cannot use conventional data managers because of performance concerns and a semantic mismatch between the analysis operations(More)
This paper describes the results of research into algorithms for realizing improved control over the distribution of router and link resources among the users of a packet-switched network. It reports the results o f simulation experiments designed to evaluate — in th e context of the current Internet architecture and protocols — the effectiveness of various(More)
Calliope is a distributed multimedia server constructed from personal computers. Preliminary performance measurements indicate that Calliope can be scaled from a single PC producing about 22 MPEG-1 video streams to hundreds of PCs producing thousands of streams. The system can store both variable-and constant-rate video and audio encodings and can deliver(More)
I/Browse: The Bellcore Video Library Toolkit is a set of tools for constructing and browsing libraries of digital video. The toolkit is designed to work with video libraries on local or network disks, CD-ROMs or a multimedia server. There are three main components, a preprocessor, a tagger, and a browser. Particular attention is focused on the tools and(More)
