  This paper proposes a scalable and resilient real-time multi-party
communication architecture for the delivery of mixed media streams, for which
content centric networking, with its intelligent network layer, is chosen for
implementation to address the shortcomings of the current IP-based Internet
architecture. Content centric networking (CCN) represents one of the major
proposals targeting future Internet architecture, and is typically optimized
for non-realtime content delivery. Proposed research in this paper addresses
the architectural challenges for large-scale deployment of CCN to serve
real-time applications from the perspective of a multi-party video conferencing
framework, with the necessary architectural components to support application-
and system-level objectives, in regards to quality of experience, resource
utilization, and scalability. We present an in-depth analysis of the proposed
architecture by first providing an analytical driven study for the system, and
then demonstrating its performance by emulating the architecture over a
test-bed with a large number of participants involved in many-to-many
communication sessions. The results suggest that the proposed architecture can
scale well above 50 participants without incurring significant penalty in
signaling, communication, and computing overheads, with capability to support
100 or more participants.
