The Collaboration for Content Delivery and Network Infrastructures: A Survey

With the explosive growth of Internet traffic and the rapid development of network technology, content delivery has become a significant service in the current Internet. However, the existing content delivery solutions, such as peer-to-peer and content delivery network, have many insufficient aspects. Meanwhile, the collaboration between content delivery and network infrastructures has been considered as a promising technique in network field. From the perspective of collaboration, content delivery systems can make full use of the network characteristics and the effective information provided by the network operators, so as to improve the efficiency of the content distribution and optimize the overall performance of the network. In this paper, we present a comprehensive survey on the collaboration for content delivery and network infrastructures. First, we provide some of the works, which have been done on collaboration solutions from two perspectives: evolutionary and revolutionary. And then, the advantages and disadvantages of these solutions are compared and analyzed from three aspects of technology, business, and standardization. Finally, we outline some challenges and research directions in the future.
