TBDS
Topolgy Based Domain Search


 
Overview

Networks are taking advantage of new physical and logical options, expanding into arenas that have not available in the past. Coupled with this growth are vast increases in the numbers of nodes that participate in network communications. In the context of the growth, we see that not only are nodes becoming mobile, large sections of the network are aquiring the characteristics of mobility in that they are not consistently or continuously interconnected. This characteristic is at odds with many applications which presume that the underlying topology is consistent and continuously interconnected. One such application is the Domain Name System or DNS.

The DNS depends on the existence of a singly rooted heirarchy and a fairly static root context. Each node is configured with a manually configured set of pointers to trusted servers and the servers have a very persistant, manually maintined file that defines the servers owning the root context. There are no currently available automated means to allow a node to find a list of servers or for servers to adjust their concept of the root context. The TBDS project is tasked with investigating some options for the reduction or elimination of static configuration within the DNS heirarchy. This quad-chart gives a high-level view of the project, and this preview describes some of the technical aspects of the approach. A technical report details our overall work plan.
