att_abstract={{Content-Centric Networking (CCN) seeks to meet the content-
centric needs of users. In this paper, we propose hybrid-
COPSS, a hybrid content-centric architecture. We build on
the previously proposed Content-Oriented Publish/Subscribe
System (COPSS) to address incremental deployment of CCN
and elegantly combine the functionality of content-centric
networks with the efficiency of IP-based forwarding including
IP multicast. Furthermore, we propose an approach for
incremental deployment of caches in generic query/response
CCN environments that optimizes latency and network load.
To overcome the lack of inter-domain IP multicast, hybrid-
COPSS uses COPSS multicast with shortcuts in the CCN
overlay. Our hybrid approach would also be applicable to
the Named Data Networking framework.

To demonstrate the benefits of hybrid-COPSS, we use a
multiplayer online gaming trace in our lab test-bed and microbenchmark
the forwarding performance and queuing for
both COPSS and hybrid-COPSS. A large scale trace-driven
simulation (parameterized by the microbenchmark) on a representative
ISP topology was used to evaluate the response
latency and aggregate network load. Our results show that
hybrid-COPSS performs better in terms of response latency
in a single domain. In a multi-domain environment, hybrid-
COPSS significantly reduces inter-domain traffic with only
a small increase in the average response latency.}},
