  • Patent number: 9979648
    Abstract: Entropy in routing tables may be increase to perform packet forwarding. Hash tables that store forwarding routes may be divided into multiple hash table segments. Forwarding routes may be stored across the hash table segments in different route segments. When looking up route segments to identify a forwarding route for a destination address of a network packet, digest values generated for previous route segments may be used to determine hash key values to identify hash table entries in a different hash table segment. The forwarding route may be identified according to the hash table entries located based on the digest values for previous route segments.

  • Patent number: 9898069
    Abstract: Disclosed are devices, systems, and methods for the use of memory including a data table configured to store a plurality of elements, wherein the plurality of elements are arranged into a plurality of buckets and each of the plurality of buckets comprising a plurality of entries. A first power domain can be associated with an entry of each bucket or with a first bucket. A second power domain can be associated with a second entry of each bucket or a second bucket. Processing logic can be configured to search for a particular value stored in an element of the plurality of elements by selecting buckets of the plurality of buckets and selecting at least one entry of each of the buckets. A programmable register can be used to select a powered state of the second power domain based on a configuration of the programmable register.

  • Patent number: 9819587
    Abstract: Indirect destination determinations for forwarding tunnel network packets may be performed. Tunneling may be initiated for network packets received at a packet processor according to a forwarding route or other prior packet processing stage, such as an access control list stage. A corresponding entry in a tunnel lookup table may be accessed to determine the tunneling to be applied to the network packet, such as Internet Protocol tunneling or Multiprotocol Label Switching tunneling. The corresponding entry may also include a pointer to a next hop address table that stores a next hop address for the tunneled version of the network packet. The tunneled version of the network packet may be forwarded to the next hop address.

  • Patent number: 8296526
    Abstract: An apparatus includes a first processor that accesses memory according to a first clock frequency, a second processor that accesses memory according to a second clock frequency, and a memory device is configurable to selectively operate according to the first clock frequency or the second clock frequency. A memory controller enables dynamic configuration of organization of the memory device to allow a first portion of the memory device to be accessed by the first processor according to the first clock frequency and a second portion of the memory device to be accessed by the second processor according to the second clock frequency.
