Coordinating Pluggable Transceiver Control in SONiC-based Disaggregated Packet-Optical Networks

Effective control of pluggable transceivers in SONiC-based packet-optical nodes is demonstrated. A workflow for multi-layer recovery upon soft failure detection is validated, showing no traffic disruption and fast node-driven coordination between packet and optical operations

Moro, "IDEALIST control and service management solutions for dynamic and adaptive flexi-grid DWDM networks", in Future Network and Mobile Summit, 2013, pp. 1-10Wavelength Switched Optical Networks (WSON) were designed with the premise that all channels in a network have the same spectrum needs, based on the ITU-T DWDM grid. However, this rigid grid-based approach is not adapted to the spectrum requirements of the signals that are best candidates for long-reach transmission and high-speed data rates of 400Gbps and beyond. An innovative approach is to evolve the fixed DWDM grid to a flexible grid, in which the optical spectrum is partitioned into fixed-sized spectrum slices. This allows facilitating the required amount of optical bandwidth and spectrum for an elastic optical connection to be dynamically and adaptively allocated by assigning the necessary number of slices of spectrum. The ICT IDEALIST project will provide the architectural design, protocol specification, implementation, evaluation and standardization of a control plane and a network and service management system. This architecture and tools are necessary to introduce dynamicity, elasticity and adaptation in flexi-grid DWDM networks. This paper provides an overview of the objectives, framework, functional requirements and use cases of the elastic control plane and the adaptive network and service management system targeted in the ICT IDEALIST project.This work was partially funded by the European Community’s Seventh Framework Programme FP7/2007-2013 through the Integrated Project (IP) IDEALIST under grant agreement nº 317999

Demonstration of SDN-based orchestration for multi-domain Segment Routing networks

This work demonstrates a hierarchical control plane architecture for Software Defined Networking (SDN)-based Segment Routing (SR) in multi-domain networks. An orchestrator application, on top of multiple open source SDN controllers, creates a hierarchical control plane architecture using northbound RESTFul APIs of controllers. The orchestrator has control, visibility and traffic engineering capabilities to manage multi-domain SR service creation. Standard southbound interfaces with proper SR extensions are exploited to manage SR tunnels in the MPLS data plane

Disaggregated, sliceable and load-aware optical metro access network for 5G applications and service distribution in edge computing

A disaggregated, sliceable metro-access ring with SDN control is demonstrated with the use case of service distribution in the edge computing nodes. Successful SDN controlled dynamic network slicing generation, load-aware bandwidth resources assignment is implemented

A control plane architecture for multi-domain elastic optical networks: The view of the IDEALIST project

A key objective of the IDEALIST project included the design and implementation of a GMPLS and PCE-based control plane for multi-vendor and multi-domain flexi-grid EON, leveraging the project advances in optical switching and transmission technology, an enabling interoperable deployment. A control plane, relying on a set of entities, interfaces, and protocols, provides the automation of the provisioning, recovery, and monitoring of end-to-end optical connections. This article provides an overview of the implemented architecture. We present the macroscopic system along with the core functional blocks, control procedures, message flows, and protocol extensions. The implemented end-toend architecture adopted active stateful hierarchical PCE, under the control and orchestration of an adaptive network manager, interacting with a parent PCE, which first coordinates the selection of domains and the end-to-end provisioning using an abstracted view of the topology, and second, delegates the actual computation and intra-domain provisioning to the corresponding children PCEs. End-to-end connectivity is obtained by either a single LSP, or by the concatenation of multiple LSP segments, which are set up independently by the underlying GMPLS control plane at each domain. The architecture and protocol extensions have been implemented by several partners, assessing interoperability in a multi-partner testbed and adoption by the relevant Internet SDO (standards development organization)
