    摘要: A method and apparatus for estimating relative network proximity between request routing agents and client agents are described herein. In one embodiment, the method includes a proximity estimation unit to send a first number of probe messages to a client agent without waiting to receive a reply message, wherein the proximity estimation unit is to receive a first set of reply messages. The apparatus also including a proximity verification unit coupled with the proximity estimation unit, to send a second number of probe messages to the client agent, and to receive a second set of reply messages.

    摘要: The invention includes a method for selecting a replicated node from a domain of replicated nodes in a computer network. The method comprises maintaining a list of the replicated nodes; receiving a name resolution request to resolve a name for the domain into a network address; selecting one of the replicated nodes based on predefined selection criteria and in response to the name resolution request; and sending a network address of the selected replicated node to a network address associated with the name resolution request.

    摘要: A network caching device includes primary storage and secondary storage. The network caching device creates a set of metafile entries, each of which contains metadata for a logical grouping of related objects cached by the network caching device, and uses the set of metafile entries to reduce accesses to the secondary storage in response to requests for the objects.

    摘要: A method and apparatus for forwarding requests in a cache hierarchy based on user-defined forwarding rules are described. A proxy cache on a network provides a user interface that enables a user to define a set of forwarding rules for controlling the forwarding of content requests within a cache hierarchy. When the proxy cache receives a content request from a client and the request produces a cache miss, the proxy cache examines the rules sequentially two determine whether any of the user-defined rules applies to the request. If a rule is found to apply, the proxy cache identifies one or more forwarding destinations from the rule and determines the availability of the destinations. The proxy cache then forwards the request to an available destination according to the applicable rule.
