Abstract

Disclosed is a method of configuring a host's System Services Control Point (SSCP) identification at a peripheral node, such that the SSCP identification can be determined dynamically. This allows the peripheral node to communicate with multiple hosts without being reconfigured. Thus, the peripheral node's unattended operation is facilitated.

Dynamic Identification of System Services Control Point

       Disclosed is a method of configuring a host's System
Services Control Point (SSCP) identification at a peripheral node,
such that the SSCP identification can be determined dynamically.
This allows the peripheral node to communicate with multiple hosts
without being reconfigured.  Thus, the peripheral node's unattended
operation is facilitated.

      SNA Services maintains a configuration record for a host
connection at the peripheral node.  The SSCP identification of the
host is a field in this record which is used as a criterion for
accepting services from a host. Support for a "wildcard" value in
this field allows the peripheral node to accept services from any
host that meets the remaining criteria.

      When a peripheral node gets its services from a different host
j (e.g., due to network configuration changes, backup hosts for
failure of primary hosts, etc.), the SCCP identification of the host
is determined dynamically from the Activate Physical Unit (ACTPU)
request. This SSCP identification is used to replace the "wildcard"
value in the configuration record.
