	att_abstract={{Content-Centric Networks (CCN) provide substantial flexibility
for users to obtain information without regard to the
source of the information or its current location. Publish/
subscribe (pub/sub) systems have gained popularity in society
to provide the convenience of removing the temporal dependency
of the user having to indicate an interest each time
he or she wants to receive a particular piece of related information.
Currently, on the Internet, such pub/sub systems
have been built on top of an IP-based network with the additional
responsibility placed on the end-systems and servers
to do the work of getting a piece of information to interested
recipients. We propose Content-Oriented Pub/Sub system
(COPS) to achieve an efficient pub/sub capability for CCN.
COPS enhances the heretofore inherently pull-based CCN
architectures proposed by integrating push based multicast
at the content-centric layer.
We emulate an application that is particularly emblematic
of a pub/sub environment—Twitter—but one where subscribers
are interested in content (e.g., identified by keywords),
rather than tweets from a particular individual. Using
trace-driven simulation, we demonstrate that our architecture
can achieve a scalable and efficient pub/sub content
centric network. The simulator is parameterized using the
results of careful microbenchmarking of the open source CCN
implementation and of standard IP based forwarding.
Our evaluations show that COPS provides considerable performance
improvements in terms of aggregate network load,
publisher load and subscriber experience compared to that
of a traditional IP infrastructure.}},
