Deploying a content delivery service function chain on an SDN-NFV operator infrastructure

Abstract

Increasing over-the-top video consumption makes the delivery of content unsustainable in the current Internet. The Internet Service Providers (ISP) have a hard time competing on value-added services with content providers and content delivery networks (CDN). We propose a new model of collaboration between content delivery actors where CDNs can deploy their software in Internet Service Providers' infrastruc-tures as NFV modules. As the ISP network state has to be kept private, a high-level SLA is used to negotiate both computing resources and connectivity, leaving it up to the ISP to optimize server placement and routes. The contribution of this paper is to formalize this problem as a Service Function Chaining Embedding problem, and to propose an algorithm to optimize the Service Function Chain to improve embedding probability and decrease consumed bandwidth in the process.
