System and method for directing clients to optimal servers in computer networks
First Claim
1. A method, comprising:
- constructing a virtual overlay network of Web routers defined on top of an internetwork communicatively coupled to one another via point-to-point links;
exchanging Web Information Locator by Distance (WILD) inter-Web router communication messages using a WILD protocol between neighbor Web routers by communicating between the neighbor Web routers, and not the other Web routers in the virtual overlay network;
constructing WILD tables containing client-to-server distance information, a WILD table constructed by each of the respective Web routers based on the WILD messages having client-to-server distance information received from other neighbor Web routers and each WILD table being stored in a computer-readable medium accessible by the corresponding Web router, wherein the client comprises any information object requesting device, or a group thereof, communicatively coupled to one or more of the Web routers and the server comprises any information object repository accessible by one or more clients; and
determining, using the client-to-server distance information contained in one or more of the WILD tables, a best server for servicing a request for a particular information object made by one of the clients.

Abstract
A communication protocol includes one or more messages passed between Web routers over a reliable transmission protocol used for inter-Web router communication. These messages include information that allows the Web routers to dynamically update mappings of client addresses or address ranges to information object repository addresses based on client-to-server distance and server load. The mappings are preferably optimal mappings of the client addresses or address ranges to the information object repository addresses and the messages report updated distances from these information object repository addresses to the client addresses or address ranges. For example, the messages may report, for each updated distance, an associated client address or address range and/or an associated anchor address of a Web router co-located with an information object repository that is the subject of the message.
