“…Upon the reception of the request, the MDA controller first configures the active probes (4). Next, the MDA issues a request (5) to the sender probe to start the measurement process by generating the sequence of bursts that emulate the service to be implemented according to the traffic specifications.…”

The automation of Network Services (NS) consisting of virtual functions connected through a multilayer packet-overoptical network requires predictable Quality of Service (QoS) performance, measured in terms of throughput and latency, to allow making proactive decisions. QoS is typically guaranteed by overprovisioning capacity dedicated to the NS, which increases costs for customers and network operators, especially when the traffic generated by the users and/or the virtual functions highly varies over the time. This paper presents the PILOT methodology for modeling the performance of connectivity services during commissioning testing in terms of throughput and latency. Benefits are double: first, an accurate perconnection model allows operators to better operate their networks and reduce the need for overprovisioning; and second, customers can tune their applications to the performance characteristics of the connectivity. PILOT runs in a sandbox domain and constructs a scenario where an efficient traffic flow simulation environment, based on the CURSA-SQ model, is used to generate large amounts of data for Machine Learning (ML) model training and validation. The simulation scenario is tuned using real measurements of the connection (including throughput and latency) obtained from a set of active probes in the operator network. PILOT has been experimentally validated on a distributed testbed connecting UPC and Telefónica premises.

“…The constant need to autonomically deploy and supervise services in a cost-effective way has driven the evolution of the control, orchestration and management planes. Velasco et al [15] propose a high-level point of view of a control, orchestration, and management architecture that enables dynamic provisioning of services based on SDN and NFV principles.…”

The Internet has been gradually evolving since its inception. In this paper, we highlight the crucial factors that have driven this evolution, and describe how the Internet is nevertheless still struggling with several critical issues that need to be solved to meet predicted requirements of future applications. We discuss possible approaches, solutions, and open issues, bearing in mind the considerable inertia of the Internet's key architectural features.

“…The Metro-Haul control plane includes the COM system [2] to enable flexible service provisioning. It requires an NS described using ETSI standard Network Service Descriptor (NSD) template consisting of VNF Descriptors (VNFDs) and Virtual Links (VLs) interconnecting VNFs [12] .…”

“…In order to support new vertical applications, Metro-Haul project [1] has designed and built a cost-effective, agile, disaggregated packet-optical metro infrastructure with compute capabilities at the network edge, addressing the capacity increase and characteristics such as low latency and high bandwidth. Metro-Haul control plane consists of the Control, Orchestration and Management (COM) system [2] , based on the principles of ETSI NFV framework and a hierachical SDN control plane, which facilitates the deployment of multilayer end-to-end network slices, including Virtual Network Functions (VNFs) in multiple datacentres (with multiple Virtual Infrastructure Managers) and simultaneously dedicates packet and optical network resources, including Layer 2 (L2) VPNs and photonic media channels.…”
