SIG-TFN: Time & Frequency Network

Providing a forum for the community working around time and frequency distribution across NRENs

SIG-TFN (Time and Frequency Network) 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 GÉANT GPPC and relevant project management/coordination function.

Main aims of the SIG-TFN:

  • 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 R&E 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.
