“…Each of the NEPHELE ToR switches is equipped with two tunable transmitters (Tx) and an equal number of optical receivers (Rx), as depicted in Figure 7. In this context, the demonstrator is composed of three fully equipped ToR switches, i.e., six transmitter and receiver assemblies that were developed, tested, and used for the demo [27,28,33]. Finally, a partially functional receiver was connected to the "dummy" ToR 0, which is in pod 1 and it was used for displaying purposes.…”

The NEPHELE hybrid electro-optical datacenter network (DCN) architecture is proposed as a dynamic network solution to provide high capacity, scalability, and cost efficiency in comparison to the existing DCN infrastructures. The details of the NEPHELE DCN architecture and its various key parts are introduced, and the performance of its implementation is evaluated through an end-to-end NEPHELE demonstrator, which was built at the National Technical University of Athens. Several communication scenarios are demonstrated in real time, exploiting a scalable optical data-plane architecture with a software-defined network (SDN) control plane capable of slotted operation for dynamic allocation of network resources. Real-time end-to-end functionality and integration of various software and hardware components are verified in a six-host prototype datacenter cluster.
