Extremely low transmission latency is one of the key features promised by 5G communication networks. Additionally, smart networking requires technologies that monitor and anticipate failures to facilitate rapid network repair.
Behnam Shariati is part of a team of researchers that has demonstrated a latency-aware optical metro network having sophisticated monitoring and data analytics capabilities. Shariati will discuss the network architecture and enabling technologies, as well as a video surveillance case of the system, during a session at the virtual Optical Fiber Communication Conference and Exhibition (OFC) in June 2021.
The demonstration features automated deployment of a video surveillance case in an edge-computing-enabled optical networking ecosystem supporting interoperability of commercial hardware and prototypes, software-defined networking (SDN) controllers, orchestrators, and open-source application programming interfaces (APIs).
"The demonstrated technologies allow an operator to receive a high-level service description from a customer and implement it end-to-end across the infrastructure – an infrastructure comprised of equipment from different vendors," said Shariati.
One of the enabling technologies is a latency probe. The probe works by injecting time-stamped traffic information into the optical network, enabling the ability to measure the round-trip latency of the system autonomously and in real time, which enables optimized allocation of 5G services across the infrastructure.
