Abstract
- Professor Claypool:
- Multimedia Networking - The Internet provides a single, best-effort class of service to all traffic. However, multimedia, specifically streaming audio and video, has timing and loss constraints that are quite different than the majority of Internet traffic. I will briefly describe areas of ongoing research to improve streaming media performance on the Internet.
- Professor Finkel:
- Load balancing is the process of moving work from a heavily loaded node in a distributed system to a more lightly loaded node. I will discuss several past projects I (and other faculty members) have been involved in load balancing in a cluster and over the Web, and discuss new research opportunities in Grid systems.
- Professor Kinicki:
- What do you do with the leftover wine? Do you drink it or let it sit overnight? The answer is that the treatment depends on the type of wine. So to with network traffic. To optimize the quality of your application, the network treatment depends on whether your application is peer-to-peer, streaming media, mice (web traffic) or elephants (long downloads). This brief discussion of Quality of Service for network traffic is closer to a research swig than a research bite.
- Professor Wills:
- Inferring Relative Popularity of Internet Applications by Actively Querying DNS Caches: We describe a novel methodology that can be used to assess the relative popularity for any Internet application based on the data servers it uses. The basic idea is to infer popularity of data servers by periodically "poking" at local Domain Name servers (LDNSs) that service Domain Name System requests from a set of users running Internet applications and determining if LDNSs have cached resource records for the data servers.
Refreshments will be served.
