“…To allow unmanaged delivery, OTT TV, to compete with Standard TV (SDTV) Quality-of-Experience (QoE), TV and video material can be locally cached [24], reducing latency to the access link, in this paper represented by a WiMAX base to subscriber station link. Whether streaming over managed or unmanaged networks, packets will be lost at the access network.…”

Driven mainly by its adoption as a new media distribution platform for content providers and its ubiquitous availability for the end user's media production and consumption, the Internet is rapidly reshaping. In particular, the stakeholders in the content distribution market are considering exploiting content delivery networks (CDNs) Everywhere solution, telcos and multiple systems operators (MSOs) including AT&T, Verizon, and Comcast can now provide their customers with a whole new experience as they can now consume the content (hosted by the network provider) on fixed or mobile devices other than the TV set alone. As a consequence, these network providers can reach more customers with their content assets. Success with mobile TV offers also may be driven by the strong growth of video-enabled smartphones: 275 million video-enabled smartphones shipped in 2010 [14].At the same time, a variety of Internet video publishers, such as Netflix*, Hulu*, BBC iPlayer*, and also IntroductionThe Internet video world is undergoing a significant transformation as a wider set of content is offered for consumption over a wider set of devices.For video services offered by network providers, the following trends can be observed. Initially, many network providers deployed Internet Protocol television (IPTV) services in a walled garden environment. Apart from being a replacement for analog television (TV) distribution, IPTV also offers interactive and personalized services, including video on demand, network-based personal video recording, and time shift Apple TV* and Google TV*, have launched new video services. They are providing their content to their end users with little involvement of the network provider.Hybrid models also exist where a telco may offer a combination of digital TV and Internet video services, as described in [6]. In such a scenario, digital TV network providers will need to expand their offer by also offering access to Internet video. They have opportunities in that they can offer better quality of experience (QoE), multiscreen differentiators, have a customer base (and billing relationship), and can position themselves as the content aggregator of choice (simplicity to end user).The network provider (telco or MSO) can play a key role in both the content delivery and content discovery. As far as delivery is concerned, it is well known that content distribution networks (CDNs) can reduce the load on the Internet and within the network provider's network [7,15,16]. With respect to discovery, customers need help in finding content that interests them, especially as the amount of available content increases. Therefore, recommender systems are often integrated with video offerings to help the end user [1,3,9,13]. The use of recommenders for the purpose of caching has also been discussed in [10]. Since the network provider has a comprehensive view of the end user's content consumption, he is (potentially) well placed to recommend content. This paper combines both key roles of content discovery and content delivery...

In order to cope with the rapidly increasing video traffic (both downloaded and streamed) during which the user reads or thinks about the content just downloaded-in the former, the content is consumed (i.e., watched, heard) as it is downloading. It follows that video cannot rely on statistical multiplexing as much as data can, and this, consequently, puts even more stress on the network. Both types of services (i.e., data and video) can benefit from a content distribution network (CDN). The principle of a CDN is that objects that require a large (and sustained) bit rate to be delivered are cached in a CDN point of presence (PoP) close to the end user. For data services this decreases the download time and hence improves the user's quality of experience. Moreover, CDNs also offload traffic requests from the origin servers and, hence, provide
