1. Experiments on Cloud-RAN Wireless Handover using Optical Switching in a Dense Urban Testbed

   Minakhmetov, Artur; Gutterman, Craig; Chen, Tingjun; Yu, Jiakai; Ware, Cedric; Iannone, Luigi; Kilper, Dan; Zussman, Gil (January 2020, Optical Fiber Communication Conference)

   Abstract: We investigate dynamic network resource allocation using software-defined networking optical controller with software-defined radios on the COSMOS testbed. 10 Gb/s capacity, deterministic low latency are maintained through user equipment wireless handover via optical switching.

3. COSMOS: Optical Architecture and Prototyping

   Gutterman, Craig; Minakhmetov, Artur; Yu, Jiakai; Chen, Tingjun; Zhu, Shengxiang; Zussman, Gil; Seskar, Ivan; Raychaudhuri, Dipankar; Kilper, Dan (January 2019, ACM SIGCOMM 2019 Workshop on Optical Systems Design)

   ABSTRACT The Cloud Enhanced Open Software Defined Mobile Wireless Testbed for City-Scale Deployment (COSMOS) platform is a programmable city-scale shared multiuser advanced wireless testbed that is being deployed in New York City [1]. Open APIs and programmability across all the technology components and protocol layers in COSMOS will enable researchers to explore 5G technologies in a real world environment. A key feature of COSMOS is its dark fiber based optical x-haul network that enables both highly flexible, user defined network topologies as well as experimentation directly in the optical physical layer. A paper on the COSMOS optical architecture was previously presented in [2]. In this talk, we briefly introduce COSMOS’ optical x-haul network with SDN control, and its integration with the software-defined radio (SDR) and mobile edge cloud.

4. Optical Physical Layer SDN [Invited]

   Li, Yao; Kilper, Daniel C. (January 2018, Journal of optical communications and networking)

   Abstract—Optical system management software has been migrating toward software-defined networking (SDN) methods and interfaces. The increased programmability of SDN promises greater flexibility, dynamic operation, and multivendor compatibility for optical systems. However, physical layer control systems are complicated by transmission engineering requirements, including quality of transmission, optical power stability, and multidomain service guarantees. These challenges and recent commercial and research efforts to address them are examined.

5. Optical Networking in Smart City and Wireless Future Networks Platforms

   https://doi.org/10.1109/ECOC52684.2021.9605836  

   Kilper, Dan; Yu, Jiakai; Santaniello, Steven (January 2021, https://www.ecoc2021.org/)

   Innovation in optical networks is essential to delivering advanced performance for future smart city and wireless networks. Incorporating optical systems research in real-world platforms presents a number of challenges, which are addressed through recent advances in the use of software defined networking and emulation.
