Content Distribution and OpenFlow: a Reality Check
Abstract
With the advent of virtualization and network function softwarization, the networking world shifts to Software Defined Networking (SDN). The OpenFlow protocol is one of the most suitable candidates to implement the SDN concept. In the meanwhile, the generalization of broadband Internet (mobile, cable, DSL, fiber etc.) has led to massive content consumption. However, while content is usually retrieved via layer 7 protocols, OpenFlow operations are performed at lower layers (layer 4 or lower) making the protocol completely ineffective to deal with content. To address this issue, we proposed and developed an API to manage content in OpenFlow networks. We implemented this API using open source software and study the impact of logical centralization suggested by SDN on network performances.
