pynetdicom.pdu_primitives.AsynchronousOperationsWindowNegotiation

class pynetdicom.pdu_primitives.AsynchronousOperationsWindowNegotiation

Representation of the Asynchronous Operations Window Negotiation primitive.

Allows peer AEs to negotiate the maximum number of outstanding operation or sub-operation requests. This negotiation is optional.

The Asynchronous Operations Window is optional and there may only be a single AsynchronousOperationsWindowNegotiation item

Identical for both A-ASSOCIATE-RQ and A-ASSOCIATE-AC

maximum_number_operations_invoked

The maximum number of asynchronous operations invoked by the AE. A value of 0 indicates unlimited operations (default 1)

Type

int

maximum_number_operations_performed

The maximum number of asynchronous operations performed by the AE. A value of 0 indicates unlimited operations (default 1)

Type

int

Examples

>>> from pynetdicom.pdu_primitives import (
...     AsynchronousOperationsWindowNegotiation
... )
>>> item = AsynchronousOperationsWindowNegotiation()
>>> item.maximum_number_operations_invoked = 2
>>> item.maximum_number_operations_performed = 1
