A perfSONAR-based Integrated Multi-domain Network Measurement Platform -- Internet Monitoring as a Service

The scale, diversity, and decentralized administration of the Internet mean that to continuously acquire the global status of the network and to timely identify the causes of communication performance degradation is reasonably difficult. However, emerging advanced network applications, which are often sensitive to communication quality and bandwidth consumption, as well as increasing security threats, strongly require a higher quality of network measurement and analysis in terms of granularity (spatial and temporal), timeliness, continuity, coverage, and reliability. Integrating multiple-location, diverse-type, and long-term measurements has been considered a key means for coping with such difficulties. In addition, the measured data and analyzed results should be flexibly shared and reused for efficiency. Therefore, a multi-domain network measurement platform should be realized, as it can provide integrated network monitoring and analysis functionality over the Internet on demand and can adapt to the purposes of the individual users (applications) and operators. In this paper, we thus briefly introduce the design principles and software implementation for a perfSONAR-based integrated network measurement system aiming at "Internet Monitoring As aService", together with a preliminary experiment using a prototype system on the Internet. With help of a function we newly designed and developed, our system can easily utilize new measurement tools and flexibly integrate and provide the measurement results of those tools to users.
