A network content service apparatus includes a set of compute elements adapted to perform a set of network services; and a switching fabric coupling compute elements in said set of compute elements. The set of network services includes firewall protection, Network Address Translation, Internet Protocol forwarding, bandwidth management, Secure Sockets Layer operations, Web caching, Web switching, and virtual private networking. Code operable on the compute elements enables the network services, and the compute elements are provided on blades which further include at least one input/output port.

Content service aggregation system

A system includes a plurality of processing clusters and a snoop controller adapted to service memory requests. The snoop controller and each processing cluster are coupled to a snoop ring. A first processing cluster forwards a memory request to the snoop controller for access to a memory location. In response to the memory request, the snoop controller places a snoop request on the snoop ring&#x2014;calling for a change in ownership of the requested memory location. A second processing cluster receives the snoop request on the snoop ring. The second processing cluster generates a response to the snoop request. If the second processing cluster owns the requested memory location, the second processing cluster modifies ownership status of the requested memory location.

Ring-based memory requests in a shared memory multi-processor

A multi-processor unit includes a set of processing clusters. Each processing cluster is coupled to a data ring and a snoop ring. The unit also includes a snoop controller adapted to process memory requests from each processing cluster. The data ring enables clusters to exchange requested information. The snoop ring is coupled to the snoop controller&#x2014;enabling the snoop controller to forward each cluster's memory requests to the other clusters in the form of snoop requests.
