Towards Neutrality in Access Networks: A NANDO Deployment With OpenFlow
A next step in the evolution of Access Networks introduces a scenario in which the fair competition among service providers is enabled through the sharing of access infrastructure. CAPEX savings or regulatory aspects are currently promoting such a scenario. By adding neutrality, the positive feedback loop includes customers, service providers and network operators. The NANDO project implements a new layer 2 approach for Neutral Access Networks. This NAN proposal includes a network operator selection mechanism, a secure instantiation of services and a Prefix-based Forwarding approach (Ethernet-PF). The OpenFlow technology has been selected for its deployment. OpenFlow is a protocol by which an external entity (controller) can control/modify the flow table of a switch, which rules the forwarding process.
