OpenFlow-Based Automatic Wavelength Selection for an Optical Packet and Circuit Integrated Network

We have been developing an optical packet and circuit integrated network (OPCInet) to provide diverse services on the same metro/core fiber network. In this paper, we propose and develop a control method to realize automatic and programmable data transfers from OpenFlow networks (OFNs) to the OPCInet. An OpenFlow controller (OFC) determines how and where to transfer each flow on the OPCInet (i.e. resource selection) on the basis of the information of users' quality-of- service (QoS) requirements, performances in the OPCInet and network traffic in the OFNs. For this, we define QoS mapping between type-of-service (ToS) and ITU-T Y.1541 service classes so that the OPCInet can provide performances satisfying each user's QoS requirement. The proposed method enables effective utilization of wavelength resources with satisfying users' QoS requirements. We implement the automatic wavelength resource selection control in the OFC. We demonstrate that the OFC selects wavelength resources successfully in accordance with our policy of wavelength resource selection.
