Naive echo-state-network based services awareness algorithm of software defined optical networks

As internet services newly emerge with diversity and complexity, great challenges and demands are presented to the OpenFlow controlled software defined optical networks (SDON) to achieve better match between services and SDON. With this aim, this paper proposes a naive Echo-State-Network (Naive-ESN) based services awareness algorithm of the software defined optical network, where the naive ESN model adopts the ring topology structure and generates the probability output result to determine the QoS policy of SDON. Moreover, the Naive-ESN engine is also designed in controller node of SDON to perform services awareness by obtaining service traffic features from data plan, together with some necessary extension of the OpenFlow protocol. Test results show that the proposed approach is able to improved services-oriented supporting ability of SDON.
