摘要： In a network environment including one or more network processing (NP) devices implementing for communicating packets, each NP device supporting a forwarding table comprising entries to enable forwarding of received data packets from a source device to a destination device according to a routing protocol via a network connection, the network device routing receiving updated forwarding table entries from one or more network control devices executing routing protocol applications, a system and method for updating forwarding table entries comprises: generating for each forwarding table entry update, a data structure indicating identification of the routing protocol application and a version of a particular routing protocol application instance generating the entry update, the data structure received by the forwarding table and incorporated within a respective forwarding table entry; identifying for deletion forwarding table entries having data structures matching a designated selection criteria; and, deleting the designated forwarding table entries. By doing this old forwarding table entries in the forwarding table are updated efficiently without disrupting packet forwarding process.

摘要： Lookup time in packet forwarding on computer networks is reduced. A first lookup is performed in a memory tree to find a first protocol forwarding entry in the memory tree. The forwarding entry includes first protocol (e.g., EGP) information and cached associated second protocol (e.g., IGP) information. Both EGP and IGP information are retrievable with the first lookup and used in the determination of an EGP route for the data packet. If the cached IGP information has been invalidated due to address updates, a second lookup can be performed to find an original IGP entry in the memory tree, the information from which can be cached in the EGP forwarding entry if a background maintenance task has finished designating all the EGP entries as having out-of-date caches.

摘要： 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.
