The lab builds networks that are fast, uninterrupted, and resilient.
AboutAbout the lab
Fast, robust, and resilient communication networks.
The Intelligent Communication Networks Lab (Oki Lab) researches and develops information and communication networks that combine high speed, reliability, and flexibility.
With advances in IoT and big data technologies, every device around us is connected to networks, and diverse services are provided through processing in the cloud and on edge servers.
The lab works broadly, from theory to implementation, on technologies for the advanced design and control of the network and computing resources that support these services.
Key terms
- Wavelength-division multiplexing (WDM)
- A technology that sends different signals simultaneously over a single optical fiber by carrying each on light of a different color (wavelength)
- SDN (Software-Defined Networking)
- An approach in which the behavior of a network is flexibly controlled in a centralized way through software
- NFV (Network Functions Virtualization)
- A technology that runs the functions of dedicated communication equipment as software on general-purpose computers
ResearchResearch themes
The lab studies optical networks, network softwarization and virtualization, and highly reliable network control, using mathematical optimization and machine learning.
*Illustrative imageElastic optical networks
Using mathematical approaches, the lab studies techniques that use wavelength spectrum resources elastically in wavelength-division and space-division multiplexed optical networks, so that they can handle demands exceeding the capacity per wavelength as well as fluctuations in demand.
*Illustrative imageSoftware-driven networks
In networks virtualized with SDN and NFV, the lab performs control based on traffic observation and user demands, and studies techniques for using network resources efficiently with mathematical optimization and machine learning.
*Illustrative imageNetworks that keep running despite failures
So that services can continue to be provided despite uncertainty in traffic volume and processing time and despite node or link failures, the lab models resource allocation with mathematical optimization, designs algorithms, and conducts experimental demonstrations.
