| Abstract | This thesis presents a mechanism for providing domain name services for dynamic hosts
in the Internet. The domain name system is a generalized mechanism to locate resources
in the Internet and also to advertise their availability. It is based on the concept of a distributed
database. Advanced technologies and changing user preferences have brought about
a significant change in the operational outlook of contemporary computer network sites by
the introduction of dynamic Internet clients that could appear as transient or mobile hosts.
A new type of resource record that contains the full qualified domain names of a dynamic
host and its primary name server is described. The domain name of primary server
in the resource record is used for indirect resolution of queries arriving at secondary name
servers. A new server- to- server protocol to preserve semantic consistency of distributed
domain name server databases is described. This new protocol mechanism is interoperable
with sites continuing to use the existing DNS service.
The proposed mechanism has been implemented and prototypes were tested in a simulation
environment. The test system was found to perform satisfactorily. A comparative
study of the performance of proposed mechanism with present domain name system operation
and extension methods proposed by others is also presented. Indirect resolution of
name server queries is shown to provide the greatest benefits while relative disadvantages of
techniques to maintain distributed database consistency by dynamic propagation of actual
updates is discussed. |
