Subarea mapping table

The subarea mapping (SAMAP) table is used to supply additional NCP connectivity information to APPN Topology and Routing Services, which can then use that information in an effort to optimize routes through the CNN. See z/OS Communications Server: SNA Operation and z/OS Communications Server: SNA Network Implementation Guide for more information about Subarea Mapping Tables.

Figure 1 illustrates definition of a SAMAP mapping table.
