  • Patent number: 8259731
    Abstract: A system and method are provided for sorting IP routing table entries in a TCAM for longest IP prefix matching LPM of destination IP addresses. The IP routing table is divided into logical blocks, for each block an associated routing entry IP prefix length. Each block is of a respective size whose proportion of the total size of the routing table is determined by the associated IP prefix length. The blocks are ordered so that the TCAM returns an LPM when queried. Starting block sizes can be initialized to proportions which reflect actual expected numbers by proportion of routing entries by IP prefix length. The blocks also grow and shrink as entries are added and deleted so as to more closely mirror real-world populations of expected entries having the IP prefix length in question.

  • Patent number: 7451387
    Abstract: Apparatus and methods for autonomously identifying and mitigating soft-errors affecting integrated circuit memory storage devices are provided. A soft-error mitigation process is invoked upon finding that an integrated circuit memory device is affected by a parity error. In a staged approach, unused memory regions of the integrated circuit memory device are reinitialized; if a redundant deployment prevails, the subsystem corresponding to the affected integrated circuit memory device is reset; memory regions having copies of contents thereof stored at remote locations are rewritten with obtained copies of the contents; and memory regions storing contents which are generated at run-time are reinitialized. Directed parity error scans are employed at each stage. If the parity error persists, one of the apparatus, and the subsystem corresponding to the affected silicon memory device is reset during a maintenance window.

  • Publication number: 20080019264
    Abstract: A system and method are provided for redundancy protection of IMA groups. A protection IMA state machine is synchronized with a working IMA state machine before a hot redundant switch is made. The SCCI number is transmitted directly from the working IMA state machine to the protection state machine over an IMA synchronization link, while delta information is transmitted from the working IMA state machine for use by the protection IMA state machine to derive the frame sequence number.
