Abstract: In a networking environment including one or more network processing (NP) devices and implementing a routing protocol for routing data packets from a source NP devices to destination NP devices via a switch fabric, with each network processing device supporting a number of interface ports, a system and method for enabling a routing system to recover more quickly that the routing protocol so as to significantly reduce the occurrence of lost data packets to a failed target interface/blade. The routing system is enabled to track the operational status of each network processor device and operational status of destination ports supported by each network processor device in the system, and maintains the operational status as a data structure at each network processing device. Prior to routing packets, an expedient logical determination is made as to the operational status of a target network processing device and target interface port of a current packet to be routed as represented in the data structure maintained at the source NP device. If the target blade/interface is not operations, an alternative route may be provided by ECMP. In this manner, correct routing of packets is ensured with reduced occurrence of lost data packets due to failed target NP devices/ports.

Abstract: A method and system is disclosed for performing a pattern match search for a data string having a plurality of characters separated by delimiters. A search key is constructed by generating a full match search increment comprising the binary representation of a data string element, wherein the data string element comprises all characters between a pair of delimiters. The search key is completed by concatenating a pattern search prefix to the full match search increment, wherein the pattern search prefix is a cumulative pattern search result of each previous full match search increment. A full match search is then performed within a lookup table utilizing the search key. In response to finding a matching pattern within the lookup table, the process returns to constructing a next search key. In response to not finding a matching pattern, the previous full match search result is utilized to process the data string.

Abstract: PROBLEM TO BE SOLVED: To provide a system and its method by which a bandwidth of a consecutive bit rate virtual path connection set up between a source node and a destination node is dynamically adjusted in a packet or cell exchange network comprising a transmission link and a plurality of interconnected nodes. SOLUTION: The network defines a bandwidth management server that accesses information relating to a network node and a transmission link. This server receives indication relating to an initial bandwidth reserved for connection every time virtual path connection or virtual channel connection is set up on the network. The server detects and uses in common the bandwidth available on the transmission link between consecutive bit rate virtual path connections whose bandwidth is adjustable in the consecutive or periodic mode and decides new bandwidth to each connection. A source node is informed of it every time new bandwidth is calculated and adjusts the bandwidth of the consecutive bit rate virtual path connection whose bandwidth is adjustable accordingly.

Abstract: Multicast transmission on network processors is disclosed in order both to minimize multicast transmission memory requirements and to account for port performance discrepancies. Frame data for multicast transmission on a network processor is read into buffers to which are associated various control structures and a reference frame. The reference frame and the associated control structures permit multicast targets to be serviced without creating multiple copies of the frame. Furthermore this same reference frame and control structures allow buffers allocated for each multicast target to be returned to the free buffer queue without waiting until all multicast transmissions are complete.
