DISTINGUISHING NETWORK VS SERVER ISSUES WHEN DIAGNOSING APPLICATION PERFORMANCE PROBLEMS

Abstract:

A facility to determine if performance issues between two host computers in a data network includes a central controller identifying endpoints of a flow path between the two hosts. The central controller communicates with endpoint network devices to initiate telemetry tagging traffic on the flow path. A collector receives telemetry communicated in a packet from network devices on the flow path. A network operator can view the collected telemetry to assess whether the performance issue is in the network or not.
