PROJECT TITLE :
An SDN-Based CDN/ISP Collaboration Architecture for Managing High-Volume Flows
The collaboration of Web service suppliers (ISPs) and content distribution network (CDN) suppliers was shown to be beneficial for both parties in an exceedingly range of recent works. Influencing CDN edge server (surrogate) choice allows the ISP to manage the rising quantity of traffic emanating from CDNs to reduce the operational expenditures (OPEX) of his infrastructure, e.g., by preventing peered traffic. At the same time, together with the ISP's hidden network data within the surrogate choice method influences the standard of service a CDN provider can deliver positively. As a large quantity of CDN traffic is video-on-demand traffic, this paper investigates the subject of CDN/ISP collaboration from a perspective of high-volume long-living flows. These varieties of flows are hardly manageable with state-of-the-art Dynamic Name Service (DNS)-based redirection, as a reassignment of flows throughout the session is troublesome to attain. Consequently, varying load of surrogates caused by flash crowds and congestion events within the ISP's network are arduous to compensate. This paper presents a completely unique approach promoting ISP and CDN collaboration based on a minimal deployment of software-defined networking switches within the ISP's network. The approach complements customary DNS-based mostly redirection by permitting for a migration of high-volume flows between surrogates in the backend whether or not the communication has state data, like Hyper Text Transfer Protocol sessions. Along with a proof-of-concept, the analysis identifies factors influencing performance and shows giant performance increases when put next to plain DNS-primarily based redirection.
