  • Patent number: 8619567
    Abstract: A system and method for delaying packet transmissions within source devices and network bridges for the purpose of reducing the worst-case delays associated with forwarding of time-sensitive packets through a bridged network. The minimal bridged network system include a first device node attached to a first network link, a second device node attached to a second network link, and a bridge connecting the first network link to the second network link. The method and system includes shaping the traffic within a source device or bridge (shaping involves spreading bunched packets over time). Within a bridge, shaping occurs at each output port of the bridge, applying a distinct shaper to the traffic coming from each of the input ports, as well as distinct shapers for the distinct traffic class coming each of the input ports.

  • Patent number: 8543771
    Abstract: The present invention is a protocol for maintaining cache consistency between multiprocessors within a tightly coupled system. A distributed directory is maintained within the data-sharing processors, so that copies can be invalidated when modified. All transfers are event driven, rather the polled, to reduce bus-bandwidth consumption. Deadlocks are avoided by placing to-be-executed command codes in the returned response packets, when the request-forwarding queues are full or not present.
