The network topology based domain name service

Multiple servers providing a single service is the trend for both supporting good quality of service and reducing the cost. This makes a great difference in domain name service. A new kind of domain name service algorithm is proposed in this paper. It was migrated from the Round-Robin DNS that was announced by NCSA. In the proposed algorithm, the standard ICMP packet is used to probe a “network topology nearest” server for a client. The minimum round-trip delay server is selected. It is convenient for client users to preserve their user transparency. The only change was made on the domain name server. Fault-tolerance is also an advantage that it inherits. Combining with future network environment, such as mobile computing, IPng, or faster network surrounding such as I2, it should be able to show good performance
