When mobile networks meet content delivery networks

In this paper we design a novel mobile network architecture where we merge the advantages of using Distributed Mobility Management (DMM) functionalities with the flexibility brought by implementing mobile Content Delivery Networks (CDN). DMM is seen as one of the key technologies allowing distribution of mobility functions (i.e., mobility anchors) up to now centralized at single and expensive points. CDN is a crucial design choice for Network Operators, which enables large scale content distribution at a reasonable cost and without overloading the operator's core network. As a result of the combination of these two concepts, this paper discusses system and architectural aspects, and provides insights into the design of mobile networks as a global delivery platform and not as a stand alone mobility service. New business opportunities derived from this novel delivery architecture are discussed, as well considerations for practical deployment in next generation cellular networks.
