End-to-end bandwidth estimation tools

Popis výsledku v původním jazyce

Speed of data transfer over a wide-area network can be limited by any of the routers or links along a network path. If the bottleneck router or link is located beyond our administrative scope, we cannot find where it is and how small it is by checking link utilisation by connecting to routers and reading its byte statistics (either by login and CLI commands or using SNMP). In such a case we can use bandwisth measurement or estimation tools run between the end points to find the size and possibly the location of the bottleneck. In this report we summarize our experience with textit{bandwidth estimation tools}, which can estimate installed or available bandwidth along a network path without access to any component along that network path and without stressing existing traffic with a large volume of testing traffic.
