Abstract
When the Internet was designed decades ago, main applications are resource
sharing such as remote login and file transfer. To support such applications, the key
principle in the Internet architecture is point-to-point communications, and the key
element is an IP address that identifies a host. Due to the flexible design of the Internet,
a wide range of new applications and services have been introduced over the
decades. The recent surge of Internet traffic is mainly attributed to applications such
as web, P2P file sharing, and video streaming. In such applications, an end user is
mostly interested in content itself, not in a particular host or its location.
Over the past few years, there have been many efforts to address the above issues
from a content centric perspective. Those proposals are collectively called Information
Centric Networking (ICN), which is largely deemed as a clean-slate approach.
Most of the ICN studies think of content as a key element and hence assume
a new paradigm by shifting from host-oriented communications to content-oriented
i
communications. Consequently, instead of locator-based routing, most ICN proposals
consider name-based routing, which decouples content production and consumption
in time and space domains. The decoupling enhances content availability and naming
persistency, and supports in-network caching, multicast and mobility.
Most of ICN proposals use content names as routing entries, and thus the routing
scalability is primary concern. ICN allows in-network caching as a built-in functionality.
However, if network nodes make caching decisions individually, duplicate
copies of the same content may exist among nearby nodes. To address these problems,
this dissertation proposes a unified framework named Coordinated Routing and
Caching (CoRC) that mitigates routing scalability and enhances the efficiency of the
in-network storage.
