    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： 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： A data transmission system (100) may include a transmitting portion (102) and a receiving portion (104). A transmitting portion (102) may include an encoder (106) that may encode data values of n bits into codes of m bits, where n is less than m. Codes may be transmitted with corresponding clock values. The absolute value of the DC component of a code summed with a corresponding clock value can be no more tan one for all code values.

    摘要： A method and a system for providing a connection using a stream identifier (“id”) are disclosed. In one embodiment, the system identifies a talker node, which provides an isochronous data stream via a communication media. Once the talker node is identified, an identifier and an sub-identifier of the talker node are identified. After identifying the identifier and sub-identifier, the stream id associated with the isochronous data stream is identified in response to the identifier and sub-identifier. Next, the system establishes at least one connection according to the stream id. When the connection between the second and talker nodes is established, the listener node reads the isochronous data stream.
