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.
