1. A client application requests a connection to the Neoview platform and passes its connection
attributes to the NDCS server.
2. The NDCS server requests connection rules from WMS.
3. WMS sends the connection rules to the NDCS server.
4. The NDCS server compares the connection attributes of the client application with the
connection rules from WMS.
5. If the connection attributes of the client application match a connection rule of a service, the
NDCS server assigns the client application's session to the service and sends a connection
complete request to the application.
However, if the connection attributes of the client application do not match any of the
connection rules, the NDCS server assigns the client session to the default service,
HP_DEFAULT_SERVICE, and sends a connection complete request to the application.
Figure 1-2 (page 19) shows how the NDCS server assigns a client session to a service.
