Title: "A Survey on Congestion Control in Content Centric Networking"
by
Mr. ABU Amuda James
Abstract:
Today's Internet has been used mainly for content dissemination and
retrieval. Internet users are increasingly interested in the data rather
than the custodian of the data resulting in a mismatch between the current
Internet architecture and its usage patterns. As a quick-to-deploy
solution, content delivery systems such as CDN and P2P were proposed and
implemented as overlays on the current IP network. These solutions are not
without drawbacks resulting in inefficient dissemination and retrieval of
contents in the Internet.
Motivated by this mismatch, a collection of future Internet architectures
has been proposed recently with the aim of re-engineering the current
Internet towards supporting named-data communication. The approach
employed in the proposed architectures is generally known as Information
Centric Networking (ICN) where content objects such as videos, documents
and photos are uniquely named, enabling in-network storage of content for
caching, point-to-multipoint communication and interaction paradigms that
separate senders and receivers.
Content-Centric Networking (CCN) is the most promising among the proposed
ICN architectures largely due to the significant attention it has drawn
from networking researchers in the past few years. In the early years of
today's Internet, a problem known as "Congestion Collapse" hit the
Internet due to lack of congestion control in the widely used transport
protocol, TCP. Although CCN designers claim that CCN eliminates the
dependency on end hosts performing congestion control and that CCN can
avoid such congestion collapse via in-network caching, practical scenarios
have emerged showing the possibility of congestion occurring in both
Interest and Data paths. This has motivated several works on congestion
control in CCN.
These works implement congestion control at end hosts (receivers) and
routers, employing different strategies. Some of the proposals leverage
some features of CNN such as multipath forwarding and Interest lifetime.
This survey first provides background information on CCN and Internet
congestion control including explanation on why the currently used TCP
congestion control in the Internet is ill-suited for CCN.
It then presents the existing congestion control proposals in CCN towards
identifying their strengths and weaknesses. In addition, it provides a
discussion on the path forward regarding congestion control in CCN.
