Content-Centric Networks (CCN) provide a substantial degree of flexibility for users and end-systems to obtain information without regard to their location or source. Publish/subscribe (pub/sub) systems have gained popularity in society to provide the same convenience for users. Currently, on the Internet, such pub/sub systems have been built on top of an IP-based network with additional responsibility placed in the end-systems and servers to do the work of dissemination. The authors propose PS-CCN to achieve an efficient pub/sub capability for CCN. PS-CCN enhances the inherently pull-based CCN by introducing the capability of multicast.
