Abstract:
A method for efficiently creating a network management station (NMS) database used to correlate information identifying an active data session between a host computer and a physical unit (PU) of a computer network with information relating to multi-protocol intermediate devices configured to carry the session data throughout the network, the host computer including a virtual telecommunication access method (VTAM) for storing a PU name associated with the active session, the method comprising the steps of:providing a channel-attached router for connectivity with the host computer; loading VTAM configuration information onto the NMS database, the VTAM configuration information including a name of the PU (PU name) and its associated identifier block number/identifier number (IDBLK/IDNUM) or control point (CP) name; extracting information at the channel-attached router relating to the active data session flowing through the router, the extracted information including local and remote media access control (MAC) and service access point (SAP) addresses associated with the session, along with the IDBLK/IDNUM or CP name of the PU; and loading the extracted information onto the NMS database to thereby enable correlation without requiring a presence on or continual communication with VTAM.
