The APPC/APPN support handles all of the SNA protocol requirements when your system is communicating with a remote system that uses the LU session type 6.2 and node type 2.1 architectures. The remote system can be any of the following systems:
vAS/400 system
vSystem/36
vSystem/38
vIBM personal computer
vDisplaywriter
vSeries/1
v5520 Administrative System
vRISC System/600 (Reduced Instruction Set Computer)
vDPPX/370 (Distribute Processing Programming Executive
vOne of the following host systems:
–System/370
–System/390
–30XX processor
–43XX processor
–9370 system
–Another system that supports the appropriate level of architecture
The AS/400 APPN support is an enhancement to the SNA Node Type 2.1 architecture that supplies networking functions. These enhancements are
vDistributed directory services
vDynamic route selection that is based on
vIntermediate session routing
vRouting of data by using transmission priorities.
With the exception of intermediate session routing, HPR builds on and uses these APPN functions. For more information on HPR, see
