The network displayed by the NED process is shown in
figure 6.1. The Nodes A-N are the ordinary FIKS nodes,
and the nodes P and Q are the SCC's. The two special
hooks at the SCC's are the Nics/Tare connections and
the lines between the nodes are trunk connections.
In figure 6.2 is shown in details how the display picture
is built.
At the nodes E and K the square section indicates the
status of the mede. The ring around the "mede" indicates
the status of the node.
At the SCC both the square box and the ring around
the box are indicating the status of the SCC, but if
a SCC status change request has been issued the box
will change to the requested state. If the request
is denied the box will return to the old state, and
if the request is accepted the ring around the box
will change to the new state too.
The trunk is divided into three pieces:
Two end-pieces called neighbour node hooks and one
center-piece called trunk.
When a trunk status is changed from one end of the
trunk the NNH at that end and the trunk will change
status. When it is reported from the other end of the
trunk that the status has been changed this NNH will
change status as well.
If node K reports a node failure at node E the NNH
at the E-end of the trunk will change status.
The trans between a SCC and the collocated node is
treated as a trunk without NNH's.
In table 6.1 the colours used for status indicating
are listed.
