ExacTCP: RFC 6349 TCP Throughput Testing


Service-level agreements for Ethernet services such as business Ethernet and mobile backhaul are typically defined at layer 2.

However, end user experience is also affected by other factors such as user applications, network servers, etc. This often creates conflicts between service providers and customers.

To measure the true bandwidth seen by the end user, service providers must turn to TCP throughput testing.

Based on the RFC 6349 standard, ExacTCP is a test methodology that accurately measures TCP throughput, RTT (round-trip time) and optimal window size.

ExacTCP provides an effective bandwidth measure as well as:

  • Faster conflict resolution
  • Real maximum throughput
  • Window-size optimization
