Providing a forum for the community working around time and frequency distribution across NRENs
The Special Interest Group on Time and Frequency Network (SIG-TFN) aims to gather and exchange experiences, ideas and knowledge on the development, deployment, testing and standardisation of Time and Frequency solutions, leading to the development of a Core-Time and Frequency Network (C-TFN). The SIG has an advisory role to the GÉANT Programme Planning Committee (GPPC) and relevant project management/coordination function.
Main aims of the group
- To provide a forum for gathering and exchanging experiences, ideas and knowledge on the development, deployment, testing and standardisation of Time and Frequency distribution across research and education networks, with a particular focus on interoperability. This will be achieved through group meetings (online and face-to-face), the use of online collaborative tools, collating and dissemination of information or organising pilot projects.
- To define agreed objectives and commitment levels related to the operation and management of a Time and Frequency Network.
- To define an agreed data management plan and having a common repository for information and data.
- To create a federated access to repositories and data.
- To make recommendations and play the role of a technical adviser.
