The continuous growth of internet traffic is significantly pushed by emerging high bandwidth demanding contents. All participants in the content provisioning process including content providers, service providers, Content Delivery Networks (CDN) and customers are influenced by bandwidth requirements. Appropriate bandwidth demand estimation is of great importance for addressing resource investment. Providers in content provisioning process need to consider cloud migration in order to minimize costs. The vertical interconnection between involved providers is necessary. Larger undertakings often perform vertical integration, thus ensuring a higher control over different segments of the process. The vertically integrated content provider's incentives for cloud migration can induce significant changes in interconnection contracts in the content provisioning process. In this chapter different methods of vertical interconnection charging among vertically integrated providers are analyzed and compared.

AbstractThe Internet is a successful network that connects people all over the world. However, it has some fundamental architectural problems which require application developers and service providers to spend a tremendous effort in combating these. Examples for these efforts are content delivery networks or mobile TCP. Thus, it can be said that the Internet is currently not fulfilling the requirements on the global network anymore. The Internet of the future, or its replacement, must solve these problems.There are multiple clean-slate approaches for information-centric networking. However, they are inherently incompatible to the Internet or applications building on it.This work presents a novel resource transport protocol that is optimized for detection by software-defined networks and may be re-routed to in-network processors. Furthermore, it is shown how this protocol can be used to support concepts of ICN even in today’s Internet. Moreover, the resource format that is used in this work is independent from the underlying network, resulting in possible reuse in other networks as well. Applications and protocols building on this resource format can thus easily be re-used in clean-slate networks like NDN.

Internet television (IPTV) is rapidly gaining popularity and is being widely deployed in content delivery networks on the Internet. In order to proactively deliver optimum user quality of experience (QoE) for IPTV, service providers need to identify network bottlenecks in real time. In this paper, we develop psycho-acoustic-visual models that can predict user QoE of multimedia applications inreal timebased on online network status measurements. Our models are neural network based and cater to multi-resolution IPTV applications that include QCIF, QVGA, SD, and HD resolutions encoded using popular audio and video codec combinations. On the network side, our models account for jitter and loss levels, as well as router queuing disciplines: packet-ordered and time-ordered FIFO. We evaluate the performance of our multi-resolution multimedia QoE models in terms of prediction characteristics, accuracy, speed, and consistency. Our evaluation results demonstrate that the models are pertinent for real-time QoE monitoring and resource adaptation in IPTV content delivery networks.
