Abstract-Internet Service Providers (ISPs) route traffic at the IP layer with the preference of less inter-carrier payments while Content Distribution Networks (CDNs) route traffic at the application layer with the preference of better application performance. Such mismatch of routing preferences leads to conflicts that eventually result in higher operational cost for both ISPs and CDNs. In this paper, we propose to make CDN and ISP routing mutually beneficial through ISP's non-uniform bandwidth charging and CDN's bandwidth cost-aware request routing. More specifically, ISPs charge different prices for traffic that traverses different types of inter-domain links and CDNs, in routing user requests to their servers, try to minimize their ISP payments by taking the pricing information into consideration. We evaluate the solution in large scale simulations. The greedy solution presents the lowest bandwidth cost for CDNs but at the expense of network performance for users. With end-to-end delay introduced as a constraint in the optimization process, the solution maintains good network performance for users while achieving significant savings in bandwidth cost. Compared with conventional nearest-available policy in CDN request routing, our solution moves significant amount of inter-domain traffic from provider routes to peer or customer routes, reducing operational costs for ISPs and CDNs.

“…Traditional CDN Request Routing improves application performance metrics such as network delay [7], server load [6] and system throughput [20], but incurs significant ISP cost. In contrast CDN Request Routing in [10] reduces ISP cost by exploiting concave nature of ISP charging functions. In this paper, we explore ways to reduce CDN server charging volume as a means to reduce ISP cost for CDN.…”

Abstract-Content Delivery Networks (CDN) are overlay network of servers being used to deliver growing traffic demands on the Internet. As a result, CDNs are facing ever-increasing operating costs. Internet Service Providers (ISP) charge CDNs on server traffic, computed using common usage-based charging models, e.g. 95th Percentile charging. We propose Network Cost Aware Request Routing, NetReq, that assign user requests to reduce server charging volume. We compare NetReq against nearestavailable server request routing in large scale simulations for both web and multicast traffic requests. NetReq reduces charging volume for both traffic request types, thereby reducing cost. NetReq provides comparable network performance for multicast traffic by introducing end-to-end delay as a constraint in the requestrouting. NetReq marginally increases network performance for web traffic, when content maybe available at every server.

As more applications of video and audio to be used more researches QoS measurement of multicast are being done nowadays. Even more experiments which are done at the international research network are more important than before. In this paper we use overlay multicast technology to construct a test-bed with overlay multicast relay (OMR) over international research network. We do multicast QoS experiments in the testbed with international research network and make analysis and comparison. Through these research works, we get different kind of performance evaluation of multicast in international research network. We propose QoS measurement method of multicast video service in the international research network.
