White Paper: Ultrastable Frequency Transfer in L-Band
Frequency dissemination in phase-stabilised optical fibre networks for metrological frequency comparisons and precision measurements are promising candidates to overcome the limitations imposed by satellite techniques. However, in an architecture shared with telecommunication data traffic, network constraints may restrict the availability of dedicated channels in the commonly used C-band. Here, SWITCH and its partners demonstrate the dissemination of an SI-traceable ultrastable optical frequency in the L-band over a 456 km fibre network with ring topology, in which data traffic occupies the full C-band.

White Paper: OAV Architectures
The advancement of orchestration, automation and virtualisation (OAV) technologies drives the transition from traditional architectures to agile solutions that can respond to the digital transformation demands. The GN4-3 Network Technologies and Services Development Work Package (WP6), Network Services Evolution and Development Task (T2) has analysed the requirements for building collaborative digital services and proposes a high-level reference architecture that can help the community design and implement their digital platforms in an interoperable way. The flexibility of the proposed blueprint architecture is presented by mapping it against different architectural solutions proposed by standardisation bodies and research projects.

OAV - Towards Collaborative Digital Services
This pamphlet about Orchestration, Automation and Virtualisation (OAV) is aimed at NRENs and R&E organisations who are on a digital transformation journey, seeking to use digital platforms in an agile way - embracing automation, modularity and flexibility to gain more efficient provisioning, and configuration consistency. A collaborative approach across the GÉANT community can bring additional benefits through sharing of knowledge and experience. To this end, the pamphlet provides an overview of the TM Forum’s Open Digital Architecture (ODA), a reference framework which provides a common understanding and generality in an environment where each NREN is free to choose its own path towards OAV - including architecture, design and implementation.

Zero-Footprint Monitoring
Zero-footprint monitoring is monitoring performed without the use of additional dedicated hardware elements. This document describes a set of new network element features that enable scalable and vendor-independent network service performance verification. It is written in a cookbook style and describes the use of standard protocols on network elements and virtual services on top of network elements, as well as the use of streaming telemetry for result transportation towards result repositories.

Data Transfer Node (DTN) Tests on the GÉANT Testbeds Service (GTS)
Many research projects need to transfer large amounts of data and use specialised Data Transfer Nodes (DTNs) to optimise the efficiency of these transfers. In order to help NRENs to better support user communities who seek to move large volumes of data across their network, a DTN Focus Group was set up in the Network Technologies and Services Development work package (WP6) of the GN4-3 project, which has performed several activities around DTN deployment, the results of which are summarised in this document.

White Paper: White Box Total Cost of Ownership
White box technology offers an opportunity for network operators in the NREN and R&E community to gain a certain level of independence from vendors as it prevents lock-in to a specific hardware or software vendor or platform. Beyond the strategic interest in a white box approach, there is an expectation of a reduction in the Total Cost of Ownership (TCO) of a white box router or network device. This document describes the different components of that cost and gives guidance on how to calculate the TCO.
