Method and system for reference counted pending interest tables in a content centric network

摘要

One embodiment provides a system for facilitating efficient communication of a collection of interests. During operation, the system receives, by an intermediate node, a first packet which has a name and a first nonce, wherein the first packet indicates a set of member interests, wherein a member interest has a name. In response to not obtaining a matching entry in a pending interest table based on the name for the first packet, the system creates a new entry in the pending interest table, wherein an entry includes a second nonce, a reference count, and a set of arrival nonces and corresponding arrival interfaces. The system sets the new entry's second nonce to a new nonce, and sets the new entry's reference count to a number of member interests indicated in the first packet. The system forwards the first packet, wherein the first nonce is replaced with the new nonce.
