Introducing SNAplus2

Security Options
With networks becoming more complex and moving to an open
architecture, security emerges as a major issue. In SNA networks
running SNAplus2, you can protect your assets by defining various levels
of security through configuration and by implementing certain types of
links.
LU 6.2 users can define session security to ensure that the proper LUs
are engaged in a session, resource security to restrict access to a
particular application, and conversation security to deny access to all
applications associated with a particular LU. Additional security is
possible through data encryption routines.
3270 emulation programs can be restricted by an administrator so that
different users have access to different LUs or different features.
Network Management Flexibility
SNAplus2 offers the following network management options:
Multiple Domain Support-Network Management Vector Transport
(MDS-NMVT)
MDS-NMVT can work as a centralized, distributed, or
hierarchical management scheme. It is based on a focal
point/entry point architecture that gives you a high
degree of flexibility.
Focal points are control nodes that manage the
network according to the data they collect from entry
points (management applications that reside on all
other nodes in the network).
• In centralized management, a single focal point acts
as a control point for the entire network.
• In distributed management, several focal points
share in managing the network.
• In hierarchical management, focal points are nested
according to function.
MDS-NMVT can thus be adapted to manage
host-mediated, standard APPN, and very large APPN
networks.
