DisNETPerf

DisNETPerf is a tool for monitoring reverse-paths, ie, from servers to customers, when the server is not under the control of the user. For doing so, it relies on the RIPE Atlas distributed active measurements platform.

Given a certain server, with IP address IP_s, and a target customer, with IP address IP_d, DisNETPerf locates the closest RIPE Atlas probe to IP_s, namely IP_x, and periodically runs traceroute from IP_x to IP_d, collecting different path performance metrics such as RTT per hop, end-to-end RTT, etc.  This data collected is then used to troubleshoot ''reverse'' paths, from the server to the target customer.

To select IP_x, DisNETPerf makes use of a combined topological and latency-based approach, using standard pings and BGP routing tables. In a nutshell, it locates the RIPE Atlas probe with minimum RTT to the selected server IP_s, among a set of prefiltered IP_x candidates, which are located at either the same AS of IP_s or in the neighbor ASes.

DisNETPerf is available at the mPlane GitHub repository, in https://github.com/fp7mplane/demo-infra/tree/master/DisNETPerf.

To run RIPE Atlas within the mPlane framework, use the code and follow the steps as described in the mPlane GitHub repository, at https://github.com/fp7mplane/components/tree/master/ripe-atlas
