Abstract
This chapter provides an overview on the recent advances and perspectives on Content Delivery Networks. The first section, the introduction, sets the context. The second section identifies the different types of current CDNs and also insights on their evolution. The third section deals with CDN interconnection, reporting work status such as IETF and ETSI. The fourth section, on CDN and virtualization, describes the related initiatives in this area, in standardization bodies as well as in experimental deployments and evaluations. The fifth section focuses on the convergence of CDNs and clouds, presenting new business opportunities for the market players, as well as technical challenges. The sixth section addresses another trend, which is the extension of CDNs to home networking and terminal devices. The last section discusses content delivery for mobile, introducing solutions that operators can to optimize their networks and avoid being overwhelmed by ever growing traffic.
