Network developments and network monitoring in Internet2
Eric L. Boyd, Susan Evett · 2007
Given that performance is excellent across backbone networks, and that performance is a problem end-to-end, it is clear that problems are concentrated towards the edge and in network transitions.To achieve good end-to-end performance, we need to diagnose (understand the limits of performance) and address (work with members and application communities to address those performance issues).We envision readily available performance information that is easy to find, ubiquitous, reliable, valuable, actionable (analysis suggests course of action), and automated (applications act on data received).The Internet2 End-to-End Performance Initative (E2Epi) currently focuses on the development and widespread deployment of perfSONAR [1][2], an international consortium developing a performance middleware architecture and a set of protocol standards for inter-operability between measurement and monitoring systems.perfSONAR is a set of open source web services that can be added, piecemeal, and extended to create a performance monitoring framework.It is designed to be standards-based, modular, decentralized, and open source.This makes it applicable to multiple generations of network monitoring systems and encourages outside development while still allowing it to be customized for individual science applications.perfSONAR is a joint effort of ESnet, GÉANT2 JRA1, Internet2, and RNP.The Internet2 Network is a hybrid optical and IP network, that offers dynamic and static wavelength services.The Internet2 Network Observatory supports three types of services: measurement, co-location, and experimental servers to support specific projects.The Observatory collects data and makes it publicly available.
