“…In [28] the authors conducted optical x-Haul emulation by leveraging Mininet Optical [29] and introduced an SDN controller for dynamic provisioning within the emulated network. When compared to SDN controller their roles and responsibilities we can consider ONE as an alternative SDN controller capable of provisioning and monitoring lightpaths and different components of ROADMs as well.…”

“…When compared to SDN controller their roles and responsibilities we can consider ONE as an alternative SDN controller capable of provisioning and monitoring lightpaths and different components of ROADMs as well. Our research differs from [28] primarily concerning the application focus, while their study delved into investigating the processing limits of baseband units (BBU), our work focuses on ONE and its usefulness e.g exploring the impact of channel bandwidth on transmission quality through varying numbers of TCP sessions as a use-case. The study conducted by the authors in [30] introduced an SDN-based application that utilizes OpenFlow [5] to implement resource allocation functions within the wavelength division multiplexing (WDM) layer.…”

Software-Defined Optical Networking (SDON) signifies a revolutionary paradigm in optical network management and provisioning. It leverages the power of software-defined networking (SDN) principles to enhance the flexibility, efficiency, and intelligence of optical networks. In the realm of SDON, we introduce the Open Networking Engine (ONE), a groundbreaking application designed to optimize White box Reconfigurable Optical Add-Drop Multiplexers (ROADMs). ONE serves as a vital bridge between cutting-edge technology and real-world network orchestration. By harnessing device's YANG Models and the NETCONF protocol, it empowers network administrators with the ability to dynamically configure, provision, and monitor ROADMs. This paper not only highlights ONE's competency in the efficient management of network resources but also underscores the substantial potential of flexgrid technology, particularly in terms of spectral efficiency. The study also delves into the impact of channel bandwidth on critical network parameters, including packet loss, round-trip time (RTT), throughput, and TCP window size. The result is a noteworthy achievement, with a 93.4% improvement in spectral efficiency realized through comprehensive signal analysis. This research highlights the promising path toward enhancing optical network performance, fostering a more agile and resource-efficient network infrastructure.

“…This work is again more suited for radio networks and does not exactly match the type of experiments we plan to do which are more ad hoc in nature. An SDN-controlled dynamic provisioning of light paths is reported in [28] for an optical x-haul (front/back/cross-haul) network. They used mininet to emulate the software part and the COSMOS infrastructure for the hardware part.…”

“…They used mininet to emulate the software part and the COSMOS infrastructure for the hardware part. The work in [28] is somewhat relevant to our project as we also plan to run SDN as a means to control our inter-testbed experiments. Again, in [29], the authors use SDN in a cloud-RAN to control the handover of mobile equipment from one Remote Radio Head (RRH) to another.…”

Future Wireless Networking Experiments Escaping Simulations

In computer networking, simulations are widely used to test and analyse new protocols and ideas. Currently, there are a number of open real testbeds available to test the new protocols. In the EU, for example, there are Fed4Fire testbeds, while in the US, there are POWDER and COSMOS testbeds. Several other countries, including Japan, Brazil, India, and China, have also developed next-generation testbeds. Compared to simulations, these testbeds offer a more realistic way to test protocols and prototypes. In this paper, we examine some available wireless testbeds from the EU and the US, which are part of an open-call EU project under the NGIAtlantic H2020 initiative to conduct Software-Defined Networking (SDN) experiments on intelligent Internet of Things (IoT) networks. Furthermore, the paper presents benchmarking results and failure recovery results from each of the considered testbeds using a variety of wireless network topologies. The paper compares the testbeds based on throughput, latency, jitter, resources available, and failure recovery time, by sending different types of traffic. The results demonstrate the feasibility of performing wireless experiments on different testbeds in the US and the EU. Further, issues faced during experimentation on EU and US testbeds are also reported.
