Monitoring

This research focusses on improving and extending perfSONAR, the infrastructure for network performance monitoring. The purpose is to make it easier to solve end-to-end performance problems on paths crossing several networks. perfSONAR delivers a set of services that offer performance measurements in a federated environment.
   


The main monitoring research areas

• Advanced Monitoring Solutions, such as of new traffic flow monitoring techniques and machine learning algorithms extending perfSONAR
• Circuit Monitoring – The integration of dynamic circuit provisioning and perfSONAR
• Network Events Management by perfSONAR
• Cross-Layer Network Monitoring in the Multi-domain Environment: Topology definitions embracing horizontal and vertical network view to allow for cross –layer monitoring complementing by monitoring of layers below IP.
• Monitoring-based Service Level Agreement Management in the multi-domain Environment
• Standardised access to the measurement tools and network monitoring data (OGF NM-WG and OGF NMC-WG).
• OAM Ethernet monitoring utilities, multi-domain aspects and perfSONAR integration
• An alternative  implementation of perfSONAR based on the NETCONF protocol
• Advanced network traffic analysis based on flows
