The PLU Connection

The application's PLU connection to the local node provides access to the PLU session between the Microsoft® SNA Server LU and a PLU (primary LU) in the host. This section describes:

• How an application opens and closes its PLU connection.
• The use of the PLU connection.

For simplicity, this section describes the PLU connection as if an application uses only a single SNA Server LU (and therefore a single PLU connection); in practice, applications can use multiple LUs.
