Usage guidelines
The exchange is a basic concept of FC. All data frames and control frames are transmitted based on the
exchange. An exchange indicates one data exchange between communication entities and can consist
of multiple bidirectional packet exchanges.
An exchange pair (initiating exchange and responding exchange) must be created for each data
exchange. Service classes that provide reliable transmission services (classes 1, 2, and 6) perform packet
acknowledgement, error detection, and packet retransmission based on the exchange pair.
