Abstract: A processor communication register (PCR) contained within a multiprocessor cluster system provides enhanced processor communication. The PCR stores information that is useful in pipelined or parallel multi-processing. Each processor cluster has exclusive rights to store to a sector within the PCR and has continuous access to read its contents. Each processor cluster updates its exclusive sector within the PCR, instantly allowing all of the other processors within the cluster network to see the change within the PCR data, and bypassing the cache subsystem. Efficiency is enhanced within the processor cluster network by providing processor communications to be immediately networked and transferred into all processors without momentarily restricting access to the information or forcing all the processors to be continually contending for the same cache line, and thereby overwhelming the interconnect and memory system with an endless stream of load, store and invalidate commands.

Abstract: Restoring of content of data blocks to non-volatile storage as the content existed at a particular instant in time. After accessing the last backup representing the most recent backup of the plurality of data blocks prior to the particular instant in time, the content of each data block represented in the last backup is written to a corresponding position in the non-volatile storage. This last backup may be an incremental backup in which only those data blocks that had changed since the immediate prior backup were actually backed up. Then, restoration occurs through each prior backup in reverse chronologic order until the full backup is encountered and restored. When restoring a backup, a data block is not restored if the data block had already been restored proceeding in reverse chronological order.

Abstract: An existing protection mechanism is enhanced through the use of an automatic protection switching protocol data unit (APS PDU). In conjunction with transmitting Ethernet frames to a second bridge over a primary path, a first bridge transmits APS PDUs to the second bridge over a secondary path.

Alternatively, after forming a regular APS PDU, protection switching may be facilitated by encapsulating the regular APS PDU with information identifying a trunk or a primary path before transmitting the APS PDU to the second bridge.
