New ETSI Telemetry Standard Improves Automation for End Users

As the scale and services offered through the optical access networks increase, it is crucial to maintain good network operation and performance. Compared to existing traditional methods, the optical access network monitoring can be improved via automated real-time data collection. Telemetry enables this process and transmits data from the optical line terminal (OLT), which is the device at the endpoint of a passive optical network, in real-time to provide information to the data collection platform. 

The new ETSI specification GS F5G-011 defines telemetry framework and requirements for access networks, allowing service providers and operators to benefit from real-time monitoring with scale, speed and automation using telemetry. The data retrieved by telemetry, together with analytics and AI, will ultimately offer end users an optimized quality of experience of their fiber to the home (FTTH) network, unlocking the potential of the fifth-generation fixed networks. 

Today, the access network deployment is based on traditional data-pulling methods, such as simple network management protocol (SNMP), syslog and command-line interface (CLI) to pull data from the OLT to monitor optical access network and troubleshoot any issues. The interface uses proprietary management information bases (MIBs) from different OLT equipment vendors, making automation a difficult task. Each request to pull data is therefore resource intensive and impacts the performance of the OLT, adding complexity because there is more than one pull request per OLT. The pulling method does not efficiently scale. 

With the flexibility of telemetry, which uses the push method to continuously stream data from the OLT, data can be selected from the OLT and transmitted in a structured format to a data collection platform for monitoring, and AI-based analytics and visualization. 

Telemetry introduces finer granular data points and more frequent data streaming in the optical access network. It enables better performance monitoring and therefore better control over large access networks. Telemetry data can assist in the prediction of network problems and take preventative actions without impacting the performance of the OLT. Operators will gain better visibility and insight into the network. They can also enhance the network operational performance by using data analytics, 

 The ETSI F5G Industry Specification Group is working on 10 other specifications and will soon release F5G passive optical networks (PONs) for industrial applications and an F5G security architecture. If you’re interested, contact isgsupport@etsi.org. 

ETSI provides members with an open and inclusive environment to support the development, ratification and testing of globally applicable standards for ICT systems and services across all sectors of industry and society. We are a non-profit body, with more than 900 member organizations worldwide, drawn from over 60 countries and five continents. The members comprise a diversified pool of large and small private companies, research entities, academia, government, and public organizations. ETSI is officially recognized by the EU as a European Standardization Organization (ESO).
