Decentralized Directory Services
|
We assert that a distributed directory
is an essential
building block for many of the new distributed applications coming online
today.
Using distributed directories represents an evolution in the way information is accessed over the Internet --- a paradigm shift from using centralized servers that concentrate processing at a few large nodes in the network to diffusing computations throughout the network. The intent of this project is to design and build TerraDir, a distributed peer-to-peer directory protocol that can be used as the basis for implementing customized directories for Internet applications. TerraDir is based upon the twin tenets of scalability and flexibility. TerraDir will scale across multiple dimensions including the number of directory entries, the number of nodes the directory is distributed across, and available network, processing, and storage resources. |

Hmm..there seems to be some imbalance....
