What Are The Stateful And Stateless Modes Of Operation? |
|
Answer» “Stateful” MODE is meant for testing networking gear which saves state per FLOW (5 tuple). Usually this is done by injecting pre-recorded CAPTURE files on pairs of interfaces of the DEVICE under TEST, and dynamically changing src/dst IP/port. “Stateless” mode is meant to test networking gear that does not manage any state per flow (instead operating on a per packet basis). This is usually done by injecting customized packet streams to the device under test. “Stateful” mode is meant for testing networking gear which saves state per flow (5 tuple).
