Content supply Networks allows the readers to appreciate the fundamentals, to spot the underlying know-how, to summarize their wisdom on innovations, rules, rules and numerous paradigms which span on vast CDNs parts. hence, points of CDNs by way of fundamentals, layout strategy, perform, recommendations, performances, structures, purposes, and experimental effects were offered in a formal order. primary equipment, tasks, major study effects, in addition to references for extra research have additionally been supplied. comparability of other layout and improvement ways are defined on the applicable locations in order that new researchers in addition to complex practitioners can use the CDNs assessment as a examine roadmap. the entire contributions were reviewed, edited, processed, and positioned within the acceptable order to take care of consistency in order that any reader without reference to their point of data and technological talents in CDNs might get the main out of it. The ebook is prepared into 3 components, particularly, half I: CDN basics; half II: CDN Modeling and function; and half III: complex CDN systems and functions. The association guarantees the sleek circulate of fabric as successive chapters construct on earlier ones.

Example text

Deployment of the market mechanisms can be done based on an SOA. In addition, replication, resource sharing, and load balancing polices need to be guided by profit-driven utility functions that satisfy QoS requirements of end users. More information on economics-informed design of CDNs and pricing of CDNs can be found in Chap. 7 and Chap. 8 respectively. 28 M. Pathan et al. 3 An Adaptive CDN for Media Streaming Hosting of on-demand media streaming service is challenging because of the enormous network and bandwidth required to simultaneously deliver large amount of content to end users.

Map the taxonomy to a few representative CDNs to demonstrate its applicability to categorize and analyze the present-day CDNs. Such a mapping helps to perform “gap” analysis in this domain. It also assists to interpret the related essential concepts of this area and validates the accuracy of the taxonomy. The remainder of this chapter is structured as follows: we start by presenting the taxonomy of CDNs in Sect. 2. In the next section, we map the taxonomy to the representative CDN systems, along with the insights perceived from this mapping.

Another work on open and adaptive streaming CDN through collaborative control on media streaming services is described in Chap. 12 of this book. 4 A Mobile Dynamic CDN Mobile networks are becoming increasing popular for distributing information to a large number of highly dynamic users. In comparison to wired networks, mobile networks are distinguished by potentially much higher variability in demand due to user mobility. Content delivery techniques for mobile networks must take into account potentially very high spatial and temporal demand variations to dynamically reconfigure the system, and to minimize the total traffic over the network backbone.
