Responder Data Flow
Responder Data Flow
Protocol and user data generally flows to and from the Compaq responder in the steps
described below. Note that the responder sends primarily responses, although cancel
and abort requests—and data indications during a data transfer—are also possible. For
the purposes of this subsection, assume that the remote initiator sends an FTAM request
and the responder returns a response to that request. This sequence of steps assumes
that you have already established an association.
The numbers shown in Figure 3-1 correspond to the sequence of steps outlined below.
1. An FTAM application, typically on a remote system, issues an FTAM request to the
FTAM initiator supporting it.
