摘要： One embodiment provides a system that forwards a packet with a hierarchically structured variable-length identifier (HSVLI) in a network (180). An HSVLI indicates a piece of content and indicates a hierarchical structure of contiguous components ordered from a most general level to a most specific level. The length of the HSVLI is not fixed. During operation, the system receives (500) a packet which contains an interest for a piece of content with an HSVLI. Subsequently, the system determines (510) forwarding information for the HSVLI based on one or more of: knowledge of content which matches the HSVLI, a forwarding policy, and contextual information about the network. Next, the system configures (520) a forwarding engine with the forwarding information. The system then forwards (530) the packet based on the forwarding information.

摘要： A Ternary Content Addressable Memory (TCAM)-based Longest Prefix Match (LPM) lookup table including a TCAM holding a plurality of prefix entries for looking up results in an associated RAM, the associated RAM storing results corresponding to TCAM match indices; additional Random Access Memory (RAM) storing results from the associated RAM; and one entry in the TCAM representing at least two entries in the additional RAM from the associated RAM, whereby at least one entry in the TCAM is made available.

摘要： The subject matter described herein includes methods, systems, and computer program products for source-aware IP routing at a media gateway. According to one aspect, a method for source-aware IP routing at a media gateway is provided. The method includes providing a packet including a layer 3 source address and a layer 3 destination address at a media gateway having a source-aware routing table. Using the destination address included in the packet, at least one entry corresponding to the destination address is located in the source-aware routing table, where the located entry contains at least a portion of a source IP address, at least a portion of a destination IP address and routing information including an interface identifier and a next hop identifier. From among the at least one located entry corresponding to the destination IP address information, at least one entry corresponding to the source IP address included in the packet is located. Based on the routing information located in the routing table, the packet is routed to the destination.
