摘要： 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. According to the system and method disclosed herein, the present invention ensures small latencies when passing through network bridges, regardless of the network topology or other concurrent data-packet transfers, subject to the restriction that the cumulative time-sensitive bandwidth flowing through any link is less than the prenegotiated rate below that of the link's cumulative bandwidth capacity.

摘要： 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.
摘要翻译：本发明是用于在紧耦合系统内的多处理器之间保持高速缓存一致性的协议。在数据共享处理器中维护分布式目录，以便在修改时可以使副本无效。所有传输都是事件驱动的，而不是轮询，以减少总线带宽消耗。当请求转发队列已满或不存在时，通过在返回的响应数据包中放置要执行的命令代码来避免死锁。
