QNET behaviour in the presence of frames received out of order

________________________________________________________________________

Applicable Environment

Topic: Network QNET
SDP: 6.4.0
Target: Any supported target

Recommendation

________________________________________________________________________

QNET has basic recovery built in - for example in a multi-packet transmission, any missing packet is re-requested. QNet was designed to have as little overhead as possible, so error recovery needs to be built into the application that makes use of qnet - things like timeouts, and error checking must be in place.
