Method for querying replicated databases

摘要

The apparatus and method of the present invention provides even loadsharing of round-robin querying of replicated databases in a network architecture which responds to network conditions. The network architecture utilizes a round-robin routing table that includes correlated index numbers, point codes and addresses of the replicated databases. The network architecture responds to incoming queries with searching of the round-robin routing table by incrementing to a successor index number and an associated point code. The network architecture may further determine whether the database at the address pointed by the point code is accessible. If not, the network architecture increments to another successor index number to locate an accessible database. When an accessible database is found, the point code is set to the address of the accessible database and the query is forwarded to that address.
