“…In one of the first works using the extension, the authors introduce a packet-circuit system controlled by OpenFlow [2]. Experimental results focused on the proof of concept and flow setup delay are given in [3] for wavelength selective switching (WSS) systems. An important characteristic of these works is that the underlying optical circuit connectivity is pre-established and mapped to each new packet flow request.…”

The development of software defined networking (SDN) has instigated a growing number of experimental studies which demonstrate the flexibility in network control and management introduced by this technique. Optical networks add new challenges for network designers and operators to successfully dimension and deploy an SDN-based in the optical domain. At present, few performance evaluations and scalability studies that consider the high-bandwidth of the optical domain and the flow characterization from current Internet statistics have been developed. In this paper these parameters are taken as key inputs to study SDN scalability in the optical domain. As a relevant example an optical ring Metropolitan Area Network (MAN) is analyzed with circuit and packet traffic integrated at the wavelength level. The numerical results characterize the limitations in network dimensioning when considering an SDN controller implementation in the presence of different flow mixes. Employing flow aggregation and/or parallel distributed controllers is outlined as potential solution to achieve SDN network scalability.

“…Therefore, in order to define a SDN solution suitable for controlling a hybrid packet/circuit data plane, the protocol itself, as well as the basic concept of flow, must be properly extended. Similar extensions were recently proposed with the intent to build an OpenFlow-based control plane for both packet and circuit networks [16,17,18,19,20,21]. However, these solutions can be applied to networks where the packet-switched domain is separate from the circuit-switched one: the SDN concept is used to implement a single, unified control plane for the packet and circuit domains and for the gateways interconnecting them.…”

Circuit and packet switching convergence offers significant advantages in core networks to exploit their complementary characteristics in terms of flexibility, scalability and quality of service. This paper considers the possibility of unifying the two different types of transport using the Software Defined Networking (SDN) approach. The proposed architecture applies a modular design to the whole set of node functions, representing the key enabler for a fully programmable network implementation. This paper also proposes a possible extension to the basic concept of flow defined by the current OpenFlow standard to properly support a hybrid network. A set of experiments are performed to assess the main functionality and the performance of the hybrid node where packet and circuit switching are assumed to be configured through the OpenFlow protocol in a fully automated way.

Various broad bandwidth services have being swallowing the bandwidth resource of optical networks, such as the data center application and cloud computation. There are still some challenges for future optical networks although the available bandwidth is increasing with the development of transmission technologies. The relationship between upper application layer and lower network resource layer is necessary to be researched further. In order to improve the efficiency of network resources and capability of service provisioning, heterogeneous optical networks resource can be abstracted as unified Application Programming Interfaces (APIs) which can be open to various upper applications through Application-oriented Integrated Control Center (AICC) proposed in the paper. A novel Openflow-based unified control architecture is proposed for the optimization of cross layer resources. Numeric results show good performance of AICC through simulation experiments.
