Abstract
A routing apparatus is located at an outbound "edge" of an administrative domain or at an inbound "edge" of an ISP or other network facility. The apparatus, which is preferably implemented in software, includes a "dispatcher." The dispatcher has a database associated therewith in which information about a "current state" of the network or some resource therein is collected and maintained. The "current state" information is generally of two types: quality-of-service (Q-o-S) information associated with transactions involving a particular Web server, or more general network resource availability information. According to the invention, a routing "policy" is defined at the dispatcher using at least one routing rule having a condition and an action. As service requests arrive at the dispatcher, each of the requests is routed to a destination by testing the current state information against the condition.
