Abstract

A technique efficiently creates a database used to correlate information identifying data session traffic exchanged between entities of a computer network with information relating to multi-protocol intermediate devices configured to carry the session traffic throughout the network. The intermediate devices are preferably routers configured to carry System Network Architecture (SNA) session traffic between SNA entities comprising a host network connection and a physical unit (PU) station. The host network connection utilizes a channel-attached router for connectivity with a host computer. The technique allows a network management station (NMS) program to establish a NMS database by obtaining a PU name associated with an active SNA session without requiring a presence on or continual communication with a virtual telecommunication access method on the host.
