    Abstract: An apparatus, and corresponding method, for performing a search for a match of at least one expression in an input stream is presented. A graph including a number of interconnected nodes is generated. A compiler may assign at least one starting node and at least one ending node. The starting node includes a location table with node position information of an ending node and a sub-string value associated with the ending node. Using the node position information and a string comparison function, intermediate nodes located between the starting and ending nodes may be bypassed. The node bypassing may reduce the number of memory accesses required to read the graph.

    Abstract: Methods and devices are provided for implementing a dual mode firewall. Some implementions provide a firewall in a network device that acts as bridge for layer 2 traffic and acts as a router for layer 3 traffic. In some implementions, a determination of whether to act as a bridge or a router for a packet is based on the configuration of the interface handling the packet. In some implementations, the network device inspects a destination of each packet to determine whether to act as a bridge or a router for that packet. The firewall screens both the layer 2 and the layer 3 traffic according to policies implement in the firewall.

    Abstract: In one embodiment, a system comprises a memory and a memory controller that provides a cache access path to the memory and a bypass-cache access path to the memory, receives requests to read graph data from the memory on the bypass-cache access path and receives requests to read non-graph data from the memory on the cache access path. A method comprises receiving a request at a memory controller to read graph data from a memory on a bypass-cache access path, receiving a request at the memory controller to read non-graph data from the memory through a cache access path, and arbitrating, in the memory controller, among the requests using arbitration.

    Abstract: A Session Initiation Protocol (SIP) proxy server including a multi-core central processing unit (CPU) is presented. The multi-core CPU includes a receiving core dedicated to pre-SIP message processing. The pre-SIP message processing may include message retrieval, header and payload parsing, and Call-ID hashing. The Call-ID hashing is used to determine a post-SIP processing core designated to process messages between particular user pair. The pre-SIP and post-SIP configuration allows for the use of multiple processing cores to utilize a single control plane, thereby providing an accurate topology of the network for each processing core.
