“…Similar interactive tools are reported in the literature as important tools for the management, testing and evaluation of networks [4], [5], [6]. Focusing on providing an effective tool mainly for advancing, testing and monitoring the Agent's functionality and performance [7], the current work presents a management tool for the Nephele Agent. The proposed Agent's tool is able to access all the information that it is directed to the data plane.…”

“…The use of the proposed management tool contributed significantly to the development of the entire Nephele data center and consequently the testing phase. Additionally, it benefits the entire system because it will still be most suitable for effectively monitoring the Agent's performance during normal operation and also it provides the means for realizing scenarios in the cases of demonstrations and presentations [7].…”

Optical switching provided the means for the development of Data Centers with high throughput interconnection networks. A significant contribution to the advanced optical Data Centers designs is the Nephele architecture that employs optical data planes, optical Points of Delivery (PoD) switches and Top of Rack (ToR) switches equipped with 10 Gbps connections to the PoDs and the servers. Nephele follows the Software Defined Network (SDN) paradigm based on the OpenFlow protocol and it employs an Agent communicating the protocol commands to the data plane. The current paper presents a management tool for the Agent. The Agent's management tool is utilized to configure the Agent, create commands, perform step operations and monitor the results and the status. Moreover, as a testing and validation tool, it plays a significant role in the improvement of the Agent's design as well as in the upgrade of the entire data center's organization and performance.

“…In the development of the NEPHELE prototype, we achieved the integration of the OCEANIA SDN controller with the NEPHELE data plane at the southbound and the NEPHELE inter-DC orchestrator (NIDO) at the northbound. The OCEANIA controller was demonstrated successfully in Reference [29].…”

“…Secondly, an SDN orchestration and control framework is responsible for the management of all the underlying data plane elements, extending the open-source SDN platforms with TDMA functionalities. From this angle, NEPHELE's framework is capable of dynamically assigning network resources directly at the optical layer [29]. Multiple algorithmic add-ons focusing on the fast resource allocation were developed and integrated to the SDN platform [30].…”

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.
