Query Routing in the TerraDir Distributed Directory

In SPIE ITCOM, August 02. Bujor Silaghi, Bobby Bhattacharjee, and Pete Keleher Abstract:We present the design and evaluation of the query-routing protocol of the TerraDir distributed directory. TerraDir is a wide-area distributed directory designed for hierarchical namespaces, and provides a lookup service for mapping keys to objects. We introduce distributed lookup and caching algorithms that … Read more

Hierarchical Routing with Soft-State Replicas in TerraDir

In The 18th International Parallel and Distributed Processing Symposium, April 04. Bujor Silaghi, Vijay Gopalakrishnan, Bobby Bhattacharjee and Pete Keleher Abstract:Recent work on peer-to-peer systems has demonstrated the ability to deliver low latencies and good load balance when demand for data is relatively uniform. We describe an adaptive replication protocol that delivers low latencies, good … Read more

Are Virtualized Overlay Networks Too Much of a Good Thing?

In The 1st International Workshop on Peer-to-Peer Systems (IPTPS’02), 02. Pete Keleher, Samrat Bhattacharjee, and Bujor Silaghi Abstract:Distributed lookup services using virtualized namespaces can be important building blocks for building sophisticated P2P applications. Namespace virtualization provides load balance and tight bounds on latency at low cost. In doing so, however, it discards potentially useful information … Read more
