Each RD gets mapped to another unique prefix at the ASBR and also that two ASBRs will create different unique prefixes. Thus, the route reflector sees different prefixes and reflects all of them. The ingress provider edge (PE) router can import the prefixes and correctly obtain the alternate paths for fast convergence. | 2010-04-01 |
20100080223 | EFFICIENT ACL LOOKUP ALGORITHMS - A rule management system and methods are disclosed. A rule management system includes a processor and an interface for receiving data comprising a plurality of data fields. The processor includes in a data structure nodes corresponding to combinations of first and second data field values. The data structure includes a node for each combination of first and second data field values for which there exists at least one rule and does not include at least one node corresponding to at least one combination of first and second data field values for which there does not exist a rule. The processor associates rules with each node of the data structure. A node and an associated set of rules for processing a data packet may be identified by determining first and second indices into the data structure that correspond to first and second data field values of the received data packet. | 2010-04-01 |
20100080224 | METHODS AND APPARATUS FOR PACKET CLASSIFICATION BASED ON POLICY VECTORS - In one embodiment, a method, comprising producing a first policy vector based on a first portion of a data packet received at a multi-stage switch. The method also includes producing a second policy vector based on a second portion of the data packet different than the first portion of the data packet. A third policy vector is produced based on a combination of at least the first policy vector and at least the second policy vector. The third policy vector including a combination of bit values configured to trigger an element at the multi-stage switch to process the data packet. | 2010-04-01 |
20100080225 | METHOD AND SYSTEM FOR ROUTING USING MULTI-STAGE ROUTE ENTRY LOOKUP - The invention relates to a method for routing packets. The method includes receiving a first packet to route, obtaining a first route entry using a first IP address associated with the first packet, where the first route entry includes a first prefix, a first route nexthop generation (RNG) and a first route nexthop pointer (RNP) to a second route entry. The method further includes comparing a route generation (RG) for the second route entry with the first RNG where the RG for the second route entry and the first RNG are equal, obtaining a first neighbor cache entry (NCE) from a first NCE pointer (NP) stored in the first route entry, and routing the first packet using the ARP information in the first NCE, where a route dependency list pointer (RDLP) in the second route entry points to the first route entry. | 2010-04-01 |
20100080226 | SERVICE PATH SELECTION IN A SERVICE NETWORK - A service chain system is provided. The system includes a packet of data that is operable to pass through a network of service nodes as defined by a service chain; and a service classification device that is operable to change the service chain based on a system performance. | 2010-04-01 |
20100080227 | Network device with proxy address resolution protocol - A network device includes a proxy ARP (address resolution protocol) unit for comparing a target IP (Internet protocol) address contained in an ARP request frame with a first set of IP addresses in a proxy ARP table of the proxy ARP unit, and for generating an ARP reply frame containing a MAC (media access control) address of the network device according to a result of the comparison. In addition, the network device includes a routing table for storing a second set of IP addresses for IP packet routing. Furthermore, the network device includes a processing unit coupled between the proxy ARP unit and the routing table. The processing unit is operable for receiving the ARP request frame, assigning an IP address to a host logging onto the network device, and updating the assigned IP address into the proxy ARP table and the routing table respectively. | 2010-04-01 |
20100080228 | Demand-based distribution of internet protocol routing information across a network - Systems and methods are described that disassociate Internet route table growth from the ability of a router to maintain service. A network operator may base their network design using predetermined devices implemented from the beginning of service as constrained routers. This eliminates concern that these devices would require upgrade or replacement in the future. | 2010-04-01 |
