ASE delivers more than one SM/SR to application
CIMD Interface Specification
If an application has logged in with a window size of X, and the ASE has accepted
it, the ASE is entitled to deliver up to X SMs or SRs to the application before
waiting for the response from the application. This is valid only if the application
is configured as auto deliver. If the delivery is not acknowledged during the
delivery timeout period, then the ASE retransmits the packet. The application can
acknowledge the delivery packets it has received in any order, but the preferred
way is to acknowledge them in the order they are received.
If the ASE is retrieving messages from the message router, then the ASE uses
only a window size of 1. The scenario can be explained with an application which
has a window size of 3, see Table 32.
