Abstract
OpenFlow is a protocol that enables networks to evolve and change flexibly, by
giving a remote controller the capability of modifying the behavior of network
devices. In an OpenFlow network, each device needs to maintain a dedicated and
separated connection with a remote controller. All these connections can be
described as the OpenFlow control network, that is the data network which
transports control plane information, and can be deployed together with the data
infrastructure plane (in-band) or separated (out-of-band), with advantages and
disadvantages in both cases. The control network is a critical subsystem since the
communication with the controller must be reliable and ideally should be protected
against failures. This paper proposes a novel ring architecture to efficiently
transport both the data plane and an out-of-band control network.
