Connection model-based control of concurrent connection count and properties

A computer program product, comprising:

• a computer readable storage device having computer readable program code embodied therewith, where the computer readable program code when executed on a computer causes the computer execute an application server to:
• receive, from a partner system, a connection request comprising a connection model key and a partner system attribute of the partner system requesting a connection;
• determine, using a predefined connection model, whether the received connection model key and the received partner system attribute respectively match a configured connection model key and a configured authorized partner system attribute within the predefined connection model;
• create, in response to determining that the received connection model key and the received partner system attribute match the respective configured connection model key and the configured authorized partner system attribute within the predefined connection model, a connection that comprises a first unique connection name derived from the received partner system attribute, where the predefined connection model comprises a connection namespace field limitation that limits a number of created unique connection names;
• enforce a limit on a number of multiplexed logical connections to the application server from partner systems that share the partner system attribute using the connection namespace field limitation within the predefined connection model;
• and
• receive additional connection requests comprising the connection model key from additional partner systems that share the partner system attribute;
• and
• where in causing the computer to enforce the limit on the number of multiplexed logical connections to the application server from the partner systems that share the partner system attribute using the connection namespace field limitation within the predefined connection model, the computer readable program code when executed on the computer causes the computer to:
• for each additional connection request:
• determine whether the limit on the number of multiplexed logical connections to the application server from the partner systems that share the partner system attribute has been reached based upon the connection namespace field limitation that limits the number of created unique connection names and based upon previously-created connection names;
• and
• create, in response to determining that the limit on the number of multiplexed logical connections has not been reached, an additional multiplexed logical connection that comprises an additional unique connection name derived from the received partner system attribute and based upon the previously-created connection names.
