ADAPTIVE MULTI-INTERFACE USE FOR CONTENT NETWORKING |
摘要 |
One embodiment provides a system that forwards a packet with a hierarchically structured variable-length identifier (HSVLI) in a network. 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 a packet which contains an interest for a piece of content with an HSVLI. Subsequently, the system determines 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 a forwarding engine with the forwarding information. The system then forwards the packet based on the forwarding information. |

1. A computer-implemented method for forwarding a packet with a hierarchically structured variable-length identifier (HSVLI) in a network, wherein the computer includes a processor, the method comprising:
performing a first lookup for a packet based on an HSVLI in a local forwarding information base to determine forwarding information for the packet, wherein the packet comprises an interest for a piece of content expressed using the HSVLI; wherein the HSVLI indicates a piece of content and is hierarchically structured, and comprises contiguous components ordered from a most general level to a most specific level, and wherein the length of a respective HSVLI is not fixed; in response to not finding a match for the HSVLI in the local forwarding information base, determining a forwarding decision for the HSVLI; configuring the local forwarding information base with the determined forwarding decision; performing a second lookup for the packet based on the HSVLI in the local forwarding information base to determine forwarding information for the packet. |
