Abstract
The success of the Content Delivery Networks (CDN) in the recent years has demonstrated the increased benefits of the deployment of some form of “intelligence” within the network. Cloud computing, on the other hand, has shown the benefits of economies of scale and the use of a generic infrastructure to support a variety of services. Following that trend, we propose to move away from the smart terminal-dumb network dichotomy to a model where some degree of intelligence is put back into the network, specifically at the edge, with the support of Cloud technology. In this paper, we propose the deployment of an Edge Cloud, which integrates a variety of user-side and server-side services. On the user side, surrogate, an application running on top of the Cloud, supports a virtual client. The surrogate hides the underlying network infrastructure from the user, thus allowing for simpler, more easily managed terminals. Network side services supporting delivery of and exploiting content are also deployed on this infrastructure, giving the Internet Service Providers (ISP) many opportunities to become directly involved in content and service delivery.
Highlights
Over the past two decades, the Internet has steadily evolved from a closed, research-focused network that was primarily used for mail and data transfer to an Internet of things, where services and contentFuture Internet 2010, 2 have become the main focus
The client-server model has remained the dominant model for providing services along that principle, it has evolved into a number of variants aimed at optimizing operations
We summarize here the significant research findings that focus on designing future Internet architecture through virtual networks, Centric Network (CCN) or Cloud computing
Summary
Over the past two decades, the Internet has steadily evolved from a closed, research-focused network that was primarily used for mail and data transfer to an Internet of things, where services and contentFuture Internet 2010, 2 have become the main focus. Internet access price have changed the expectations of end users They are no longer satisfied with an interconnected hosts view of the Internet and are more concerned with services and, increasingly, content. New qualifiers such as “user-centric”, “service-centric” and “content-centric” have emerged and reflect the new focus of user communities. The outermost circle is composed of the access networks, connected to the edge routers These networks vary widely depending on the underlying access technologies; they might be either wired (e.g., DSL, Cable) or wireless (e.g., LTE, WiFi) and will support any network-capable device, from PCs to “smart” phones. The access networks offer a wide range of data transfer speed depending on the technology used, the available bandwidth, the customer’s subscription plan, etc
