A method for reassigning flows to cores in a multi-core network device includes receiving a packet flow and periodically determining a packet rate of the flow and the processing load on each of the worker cores. Unassigned flows are assigned to the least loaded core. If an assigned flow has a packet rate that exceeds a particular threshold proportion of the processing capacity of the currently assigned worker core, reassigning the flow to the lowest loaded worker core unless the resulting load would exceed the current load on the currently assigned worker core.

Information representing a plurality of clients on a network is stored in a data structure. The data structure may be stored within a server or agent in a content delivery network and may include client network address information. The data structure is dynamically compressed based on network proximity information relating to the clients.

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.

A method and apparatus for a rumor based protocol for distributed state synchronization between request routing servers have been described. State synchronization is maintained between routing servers via agents that respond with information requested by the servers.

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.

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.

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.
