A network device, such as a router or switch, uses multiple forwarding and control processors that operate different protocols or operating systems to route a packet in a computer network. A support stack module determines which processor a packet is routed to and converts the packet format, if necessary, for compatibility with the processor. When a packet is directed to a control processor, its associated support stack module simulates the forwarding plane interfaces. After processing the packet is routed onto the network.

Implementation of control plane protocols and networking stacks in a distributed network device

A method and apparatus to route information in a network is described. A technique is described to search for routine information that uses a first technique on at least a portion of a first value of a network address and a second technique on at least a portion of a second section of an address. In particular, the first value is associated with an aggregation identifier, and compared to a unique prefix. In this way, address identifiers may be generated, and this identifier is used to search for routing information.

Method and apparatus to improve network routing

A method and apparatus to perform network routing using an improved routing table, search algorithm and update algorithm are described.

Method and apparatus to perform network routing using multiple length trie blocks

A method and apparatus to search for routing information is described. According to an embodiment, a technique is described to search for routing information that uses a first technique on at least a portion of a first section of an address and a second technique on at least a portion of a second section of an address. In one embodiment, a best-match technique, such as a Longest Prefix Match technique, is used on at least a portion of a topology section of an address, and an exact-match technique is used on a portion of an interface ID of the address.
