    Abstract: A Queue Manager (QM) system and method are provided for communicating control messages between processors. The method accepts control messages from a source processor addressed to a destination processor. The control messages are loaded in a first-in first-out (FIFO) queue associated with the destination processor. Then, the method serially supplies loaded control messages to the destination processor from the queue. The messages may be accepted from a plurality of source processors addressed to the same destination processor. The control messages are added to the queue in the order in which they are received. In one aspect, a plurality of parallel FIFO queues may be established that are associated with the same destination processor. Then, the method differentiates the control messages into the parallel FIFO queues and supplies control messages from the parallel FIFO queues in an order responsive to criteria such as queue ranking, weighting, or shaping.

    Abstract: A time-based system and method are provided for controlling the management of cache memory. The method accepts a segment of data, and assigns a cache lock-time with a time duration to the segment. If a cache line is available, the segment is stored (in cache). The method protects the segment stored in the cache line from replacement until the expiration of the lock-time. Upon the expiration of the lock-time, the cache line is automatically made available for replacement. An available cache line is located by determining that the cache line is empty, or by determining that the cache line is available for a replacement segment. In one aspect, the cache lock-time is assigned to the segment by accessing a list with a plurality of lock-times having a corresponding plurality of time duration, and selecting from the list. In another aspect, the lock-time durations are configurable by the user.

    Abstract: A cut-through system and method are provided for scheduling information in an information distribution device. The method receives a plurality of information streams. A master schedule is created to select messages from the information streams for transfer to a corresponding plurality of remote links. The messages (e.g., packets) may have either a fixed or variable length. The master schedule is responsible for managing a communication link overall maximum bandwidth, and a message bandwidth for each remote link. Concurrently, an underrun schedule is created to select segment rates for a first group of messages destined to corresponding first group of remote links, and manage the message segment rate for the first group of messages. For example, the first group of messages may be destined to remote links that are sensitive to underrun.

    Abstract: A system and method are provided for managing transient data in cache memory. The method accepts a segment of data and stores the segment in a cache line. In response to accepting a read-invalidate command for the cache line, the segment is both read from the cache line and the cache line made invalid. If, prior to accepting the read-invalidate command, the segment in the cache line is modified, the modified segment is not stored in a backup storage memory as a result of subsequently accepting the read-invalidate command. In one aspect, the segment is initially identified as transient data, and the read-invalidate command is used in response to identifying the segment as transient data.
