Dependent LU Requester (DLUR)
This section does not apply to LEN nodes.
As well as providing direct access to a host computer, SNAplus2 can also
provide DLUR facilities.This feature enables sessions for dependent LUs
to span multiple nodes in an APPN network, instead of requiring a direct
connection to the host.
DLUR on the SNAplus2 node works in conjunction with Dependent LU
Server (DLUS) at the host to route sessions from dependent LUs on the
SNAplus2 node across the network to the DLUS host. The route to the
host can span multiple nodes, and can take advantage of APPN's
network management, dynamic resource location, and route calculation
facilities.
PU Concentration
As well as providing direct access to a host computer, SNAplus2 can also
provide PU concentration facilities. This feature enables other computers
to use SNAplus2 resources to access a host computer instead of requiring
a separate connection to the host from each computer.
Figure 1-2 illustrates the PU concentration feature.
