Abstract
A load balancing server system includes a plurality of servers. A server has a dispatcher module, a request handler module, a cache and a local database. A load balancer receives requests for information from clients and distributes the requests among dispatcher modules of the plurality of servers in a balanced manner. The dispatcher module receives a request for information, calculates an identifier of a server from a subset of a hash result responsive to the request, routes the request to the server identified by the identifier, and provides information in the response to the client that requested it. The request handler module receives the request routed by the dispatcher module, determines the requested information by searching the cache and/or the local database, and provides the determined information to the dispatcher module.
