Creating scalable and Flexible future-Proof Networks with Programmable Optical System-on-Chip
Joost Verberk, Director of Product Management, EFFECT Photonics

Digitalization impacts all of our lives every day: in entertainment, healthcare, agriculture, and more. The demands a more digitized society puts on telecom- and cable operators are growing exponentially, but their business models struggle to keep up. Therefore a paradigm shift is needed, allowing for scalable and flexible future-proof networks. Software plays a large role in this transition, with innovations like NFV and SDN playing a key role. However, to take full advantage we need to push these advances further into the physical, optical layer. This is why Photonic Integration and Programmable Optical System-on-Chip technologies are key enablers of a truly future-proof network.

Resilient, Quantum-Secured, Time Deterministic and Programmable Network Interface Card for 5G RAN
Reza Nejabiti, Ekin Arabul, University of Bristol

The urge for flexible and secure communications is requiring new network technologies. Our time-deterministic and programmable network solutions have been demonstrated to provide high bandwidth and low latency for both fronthaul and backhaul of 5G Networks with WDM and TDM capabilities. For the requirements of 5G RAN, the interfaces are being extended with O-RAN compatibility for improved access. Also, safety measures of 5G are addressed by employing a QKD-enabled encryptor for unconditional security, whilst the Network Coding based resilience provides minimum downtime. Programmable security and resilience are ensured by the SDN controller, which enables resilient links and assigns encryption schemes from the encryption library. We have been improving this solution to place multiple users and applications sharing more than one QKD system in a beyond-5G network. Moreover, programmable hardware will provide time-deterministic flexibility in terms of security and resilience to enable the slicing of network and quantum resources at the time-slot level.
