Control Orchestration Protocol: Unified Transport API for Distributed Cloud and Network Orchestration

In the context of the fifth generation of mobile technology (5G), multiple technologies will converge into a unified end-to-end system. For this purpose, software defined networking (SDN) is proposed, as the control paradigm will integrate all …

Demonstration of Adaptive SDN Orchestration: A Real-Time Congestion-Aware Services Provisioning Over OFDM-Based 400G OPS and Flexi-WDM OCS

In this Paper, we experimentally demonstrate highly flexible and intelligent interdomain coordinated actions based on adaptive software-defined networking (SDN) orchestration. An advanced multidomain multitechnology testbed is implemented, which …

All-Optical Programmable Disaggregated Data Centre Network Realized by FPGA-Based Switch and Interface Card

This paper reports an FPGA-based switch and interface card (SIC) and its application scenario in an all-optical, programmable disaggregated data center network (DCN). Our novel SIC is designed and implemented to replace traditional optical network …

Experimental Demonstration of Multivendor and Multidomain EON With Data and Control Interoperability Over a Pan-European Test Bed

The operation of multidomain and multivendor EONs can be achieved by interoperable sliceable bandwidth variable transponders (S-BVTs), a GMPLS/BGP-LS-based control plane, and a planning tool. The control plane is extended to include the control of …

SDN-Enabled Sliceable BVT Based on Multicarrier Technology for Multiflow Rate #x002F;Distance and Grid Adaptation

We propose a sliceable bandwidth variable transceiver (S-BVT) architecture suitable for metro/regional elastic networks and highly scalable data center applications. It adopts multicarrier modulation, either OFDM or DMT, and a cost-effective …

First Demonstration of Cognitive SDN Orchestration: A Real-Time Congestion-Aware Services Provisioning over OFDM-Based 400G OPS and Flexi-WDM OCS Networks

Evaluation of Function-Topology Programmable (FTP) Optical Packet/Circuit Switched Data Centre Interconnects

An adaptive optical data center network architecture is, for the first time, proposed and simulated. Data center traffic loads are efficiently accommodated by FTP solution, supported by synthetic optical packet/circuit switching scheme and dynamic …

First Demonstration of Multi-Vendor and Multi-Domain EON with S-BVT and Control Interoperability over Pan-European Testbed

The operation of multi-domain and multi-vendor EONs can be achieved by interoperable Sliceable Bandwidth Variable Transponders, a GMPLS/BGP-LS-based control plane and a planning tool. This paper reports the first full demonstration and validation …

100G beyond Ethernet Transport for Inter- and Intra-DCN Communication with Solutions and Optical Enabling Technologies in the ICT STRAUSS Project

A multi-domain optical infrastructure with end-to-end Ethernet transport capability can deliver Ethernet services over a large scale and provide a promising solution for inter data center networks (DCN) communication. The already existed metro and …

IDEALIST Data Plane Solutions for Elastic Optical Networks

The elastic optical networks paradigm offers a competitive solution in terms of resource utilization to cope with the ever-increasing traffic demand. Specifically, the ability to make a number of previously fixed transmission parameters tunable, for …
