NMVT Routing
When SNAplus2 receives an NMVT from a remote node, it uses the MS
major vector key and the destination application name subfields of the
NMVT to determine to which MS application to send the NMVT in the
following order of preference:
1. SNAplus2 attempts to find an NMVT-level application that has
registered with an application name matching the NMVT's
destination name, in the following order of preference:
a. An application that has registered to accept the specific major
vector key carried on the incoming NMVT
b. An application that has registered to accept SNA Service Point
Command Facility (SPCF) keys, if the major vector key is in the
range 0x8061–0x8064
c. An application that has registered to accept all keys
2. If SNAplus2 cannot find a suitable NMVT-level application,
SNAplus2 attempts to find an MDS-level application that has
registered with an application name matching the NMVT's
destination name and has registered to accept NMVTs after
conversion to MDS_MUs. The order of preference for selecting an
application that can accept the appropriate major vector key is the
same as for NMVT-level applications.
