Abstract: Gathering network service performance parameters in multi-vendor environments was for a long time a challenge. It required either the use of dedicated hardware probes which increased the hardware footprint and the complexity of the PoP configuration or the use of proprietary, vendor-specific, and non-interoperable features on network elements. In the recent couple of years, some standard protocols for network performance evaluation like TWAMP (Two Way Active Measurement Protocol) started to appear as a regular feature in network elements of different vendors. We present an approach that leverages capabilities offered by network devices of multiple vendors for monitoring purposes. Specifically, these can be used as clients/servers of probing mechanisms, i.e. Two-Way Active Measurement Protocol (TWAMP) avoiding the use of external monitoring systems. Measurements from the monitoring process are collected in a streaming telemetry fashion providing real-time information on the network performance. We showcase such mechanisms using virtual routers (Cisco, Juniper) deployed in GÉANT Testbeds Service (GTS) and virtual services on top of the routers. Conducted experiments illustrate that using network devices for service monitoring provides accurate per-segment performance evaluation essentially comparable to the performance of external monitoring mechanisms.
Bio: Pavle Vuletić obtained his BSc, MSc and PhD in Computer Systems and Network Architecture from University of Belgrade, School of Electrical Engineering. He used to work on all the positions from network engineer to the deputy director of AMRES, national research and education network, being responsible mainly for network development. He is currently associate professor at the University of Belgrade, School of Electrical Engineering at the Department of Computer Engineering and Information Theory, teaching Advanced Computer Networks, Data security and Software Defined Networks courses. His research interests span from network management principles and software defined networks to network and service performance and network security. Pavle Vuletić leads WP6 task 3 - Monitoring and Management in the current GN4-3 project
