The SNALINK environment interfaces between the TCP⁄IP environment’s SNAIUCV driver and the customer’s SNA network. SNALINK communicates with one or more instances of SNALINK at remote nodes, using the SNA LU type 0 protocol. See Figure 1 for a description of the SNALINK environment interfaces.
Figure 1. SNALINK environment interfaces
Each SNALINK environment can communicate with up to 9999 SNALINKs
simultaneously. The number of connections is determined by the parameters
you pass to the SNALINK cataloged procedure. The default is 6 sessions
running in dual mode for a total of 3 SNALINKs.
- When operating in single mode, SNALINK opens one full duplex session.
- When operating in dual mode, SNALINK opens two System Network Architecture (SNA) sessions for each remote logical unit (LU) with which it communicates, one for sending and one for receiving.
