Project List

1. MUX
   a. Given set of streams that are expected in a MUX -- derive a good structure of hierarchical MUX (priority bins). Questions: a) Should it be hierarchical. b) How to form the hierarchy. c) What performance will it have?
   b. Study the advantages/disadvantages of feeding one phase of hierarchical MUX into the other.
2. Implement prioritizing mechanizm (fair queueing) for Internet traffic. Possibilities: a) Web Server side (HTTP level / TCP level) b) Client Side (e.g. between FTP and Browser).
3. Virtual path planning:
   a. Suggest an algorithm for virtual path design whose major objective is efficient failure recovery (tradeoff - between the amount of work to move the VP, to the likelihood of finding an empty space).
   b. Consider all factors for VP design and propose the parameters on which a VP algorithm should work (input is routing of sessions, output is VP design).
4. Quality of Service:
   a. Study the issue of Quality of Service in IP networks.
   b. How QOS in IP networks can/should be mapped into ATM standards?
   c. Differentiated Services in IP: How this new approach will be used to provide QOS in IP networks?
5. Caching:
   a. Compare local caching/prefetching to pool(proxy) caching/prefetching.
   b. Evaluate the value of prefetching.
