“…4 (f) displays the BER for the long-haul network scenario, where the worst-case scenario corresponds to the voyager modulation of 16QAM. The increased BER corresponding to the 100km and 200km cases are due to the amplifier noise and the dispersion imposed by the optical fibre transmission [28].…”

This paper reports an FPGA-based P4-enabled Smart NIC solution which is designed and implemented for webscale cloud and to meet 5G/Beyond 5G networking requirements. The P4-enabled Smart NIC solution leverages the open standards, platforms and software-defined approaches, responds to the real time Data Centre Networking service requests, in particularly, enables the end-to-end network slicing, which is one of the critical requirements of multi-tenancy 5G network. We discussed the possibilities and challenges of P4 specification implementation in the FPGA to realise the Smart NIC functionalities. And after that, we showed its data plane programmability and flexibility with P4 features. Furthermore, we demonstrated its application scenario in an 5G environment mainly focusing on edge Data Centre to core Data Centre network slicing. The setup interconnects the P4enabled Smart NIC with optical Bandwidth Variable Transponders, and the system offers agile 100Gbps interface to transport the packets through P4-defined data plane for L2/L3/L4 parsing and action. The P4-enabled Smart NIC can change the data plane pipelines in seconds, and it can achieve maximum 84.8Gbps throughput. With P4 programmed hardware offloaded Segment Routing can produce 30% more bandwidth than without.

“…The fourth stage of the TSON evolution is building a state-of-the-art disaggregated edge node to support both metro and long-haul networks [14]. The reason behind creating such a disaggregated edge node for the first time is the need for a flexible and programmable edge node architecture providing an interface between the 5G access and transport network.…”

“…In addition, it provides access to a highly programmable coherent variable bandwidth transponder suitable for spectrally elastic long-haul transmission. The Voyager is a Broadcom Tomahawk-based switch with added dense wavelength division multiplexing (DWDM) ports, acting as a disaggregated optical transponder [14]. It hosts multiple BVTs that are capable of dynamically allocating variable spectral width and reach by modifying the device parameters.…”

“…In the extension scenario, the ingress TSON edge nodes are responsible for parsing, aggregation, and mapping of any input traffic combination with different bandwidth into converged 40 Gbps Ethernet output, whereas the egress edge nodes have the reverse functionality. The disaggregated edge nodes are evaluated at the same time for both 8 km metro and 200 km long-haul networks and the evaluation results are available in [14]. Results showed that low latency and power penalty for both metro and long-haul networks.…”

Time Shared Optical Network (TSON): A Programmable Network Edge Solution for Multi-Access Support

et al. 2019

View full text Add to dashboard Cite

The time shared optical network (TSON) has been proposed as a dynamic optical transport network solution to provide high bandwidth and low latency connectivity in support of 5G technology and beyond. This work reviews the TSON evolution stages developed in the framework of the U.K. national project Towards Ultimate Convergence of All Networks (TOUCAN). The details of the TSON architecture and its various development phases are discussed, and the performance of its latest implementation is evaluated through relevant demonstration activities across the Smart Internet Lab’s 5G (5GUK) test network.

Novel programmable disaggregated edge node supporting heterogeneous 5G access technologies

Abstract: We demonstrate a programmable disaggregated edge node in support of both metro and long-haul networks. This solution is successfully evaluated through Bristol's City Metro Network, over 100km and 200km optical fibre with a low power penalty.
