Abstract:
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 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 tra#c with a large volume of testing tra#c. 1 What are bandwidth estimation tools? Installed bandwidth along a network path and even more importantly available bandwidth, that is a part of the installed bandwidth, which is currently not used by tra#c, are very important characteristics of network potential performance for any new tra#c submitted to the network. Available bandwidth can be monitored by several techniques: Reading router interface byte counters read by CLI commands or SNMP (which allows us to compute current load, which is a complement to available bandwidth)
