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
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.
