ENP Newswire - 30 May 2014

Release date- 28052014 - KDDI R&D Laboratories, Inc., Mitsubishi Electric Corporation, National Institute of Information and Communications Technology, Keio University, Ixia Communications K.K. and TOYO Corporation have successfully built interoperable 100Gbit/s-class core, metro or access optical networks using SDN technology.

The technology tested this time is expected to be applied to the technology realizing a wide-area cloud network that connects data centers and handles large-volume of data.

This open interoperability demonstration was conducted at the 10th International Conference on IP + Optical Network (iPOP2014) held in Musashino-city, Tokyobetween May 22 and 23.

The volume of data transmitted within or outside data centers has dramatically increased with the spread of cloud business and use of big data, and it is expected to be about 8 times more in 2020 than that in 2012. In light of this, the network within and around data centers will require 100Gbit/s-class optical network devices and the mechanism to separate and manage network resources for efficiently converging various services having different communication qualities, bandwidths and such in a single carrier's network.

On the other hand, an increase in the operational cost would be an issue when the network comprised of multiple devices and networks achieves higher speed and becomes more complicated.

Though the technology to enable integrated management of such a complicated network by use of open source interfaces such as SDN/OpenFlow has attracted attention as a means of reducing the operational cost, integrated management of a large-scale network handling a large volume of data with a single device has been difficult to achieve.

These six organizations were the first in the world to witness the Software Defined Transport Network successfully controlling a large-scale network including 100Gbit/s-class transport network in an integrated manner. To enable such control, each network control device deployed in the core, metro or access optical network has provided information to the integrated control system (SDN controller), considering the physical network controlled by itself as a simplified logical network.

An open demonstration at iPOP2014, the international conference held between May 22 and 23, showed visitors a virtual optical network built between emulated data centers with 100Gbit/s optical network devices (prototypes). The metro core optical networks were built as optical networks connecting data centers with 100Gbit/s wavelength division multiplexing equipment (supplied by Mitsubishi Electric) and 100Gbit/s-class optical packet and circuit integration switches (supplied by NICT).

In the access part connecting to emulated data centers (supplied by IXIA and TOYO), an 'elastic6' device prototype of next-generation optical aggregation network8 (supplied by Keio Univ.) was deployed, and the optical network built with different types of devices was controlled by the SDN/OpenFlow-based integrated control system (supplied by KDDI R&D Labs.). The integrated control system built a virtual optical network at the request (request for a bandwidth) from data center users.
