SNA and APPN
As well as including subarea networks, many networks today also use
APPN. A purely APPN network is decentralized. It is made up of
interconnected nodes that communicate as peers across local and
wide-area networks.
A sample APPN network is shown in Figure 1-2, “Portion of a Sample
APPN Network.” This example includes a network node in the APPN
network that also belongs to a subarea network; that node can provide
the APPN nodes with access to host resources (alternatively, the host
could be part of the APPN network).
