SNA Terms and Concepts
Basic APPN Concepts
only a single link to an adjacent network node server and a link to the
connection network, instead of configuring every possible link to every
node.
To use the connection network feature, an APPN network must meet the
following conditions:
• The nodes in the APPN network must be linked using switched media
such as token ring or Ethernet (see “DLCs”).
• All of the links in the APPN network must use the same media.
• The APPN network that contains the connection network must be
fully connected. In a fully connected network, each node has at least
one link that supports CP-CP sessions to an adjacent node.
In a connection network, the SATF serves as a virtual routing node
(VRN) that attaches directly to each node in the connection network. The
name of the connection network serves as the name of the control point
for the VRN. The VRN supports the direct routing of session data
between any two nodes in the connection network, but it does not
establish CP-CP sessions with other nodes and it does not generate
TDUs. Each node in the connection network requires only a link to its
network node server.
The link definitions needed when using a connection network are shown
in Figure 1-11, “Definitions Needed for Direct Links Using a Virtual
Node.” By using a virtual node, the connection network supports direct
links between Node EN1 and every other node in the APPN network, yet
it requires only two link definitions.
