A Survey on Congestion Control in Content Centric Networking
PhD Qualifying Examination 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.
