Hash-Based Forwarding In Content Centric Networks

摘要

A method implemented by a network element (NE), comprising obtaining a first mapping between a first content name identifying a content data in a content centric network (CCN) and a first hash value of at least a portion of the first content name, wherein the first content name comprises a character string in a hierarchical namespace, receiving, via a receiver of the NE, an initial packet comprising an initial hash value from the CCN, determining, via a processor the NE, that the initial hash value in the received initial packet matches the first hash value in the obtained first mapping, replacing, via the processor, the initial hash value in the received initial packet with the first content name in the matched first mapping to produce a translated initial packet, and forwarding, via a transmitter of the NE, the translated initial packet comprising the first content name to a connected end host.
