Abstract:
A method for efficiently correlating information pertaining to System Network Architecture (SNA) host and physical unit (PU) entities of a mixed Advanced Peer to Peer Networking (APPN) and Data Link Switching (DLSW) computer network having a local DLSw device associated with an APPN device and further configured in a peer connection relationship with a remote DLSw device, the peer connection relationship including a DLSw circuit, the method comprising the steps of:identifying a SNA session path as using Dependent Logical Unit Requester (DLUR) services of the APPN device; obtaining media access control (MAC)/service access point (SAP) addresses pertaining to the DLUR services of the APPN device and PU; determining the order of the peer DLSw devices in the network; and drawing the topology of the entities and devices in the computer network.
