About links
Subzones are connected to other subzones
and zones via links. For a call to take place,
the endpoints involved must each reside in
subzones or zones that have a link between
them. The link does not need to be direct; the
two endpoints may be linked via one or more
intermediary subzones.
Links are used to calculate how a call is routed
over the network and therefore which zones
and subzones are involved and how much
bandwidth is available. If multiple routes are
possible, your VCS will perform the bandwidth
calculations using the one with the fewest
links.
You can configure up to 3000 links.
Default links
If a subzone has no links configured, then
endpoints within the subzone will only be
able to call other endpoints within the same
subzone. For this reason, when a subzone is
created, it is automatically given certain links.
See the
Automatically created links
section for
more information.

Node 1, Node 2
Select the names of the two subzones, or the
subzone and zone, between which you want to
create a link.
Pipe 1, Pipe 2
If you want to apply bandwidth limitations to
this link, select the pipe(s) to be applied.

About default links
If a subzone has no links configured, then
endpoints within the subzone will only be
able to call other endpoints within the same
subzone. For this reason, the VCS comes
shipped with a set of pre-configured links and
will also automatically create new links each
time you create a new subzone.
Calls will fail if links are not configured
!
correctly. You can check whether a call
will succeed, and what bandwidth will
be allocated to it, using the command
xCommand
CheckBandwidth.
Pre-configured links
The VCS is shipped with the Default Subzone,
Traversal Subzone and Default Zone already
created, and with default links pre-configured
between the three which are named as follows:
•
DefaultSZtoTraversalSZ
•
DefaultSZtoDefaultZ
•
TraversalSZtoDefaultZ
You can edit any of these default links in
the same way you would edit manually
configured links. See
Creating and
editing links
for more information.
If any of these links have been deleted, they
may all be automatically restored using:
xCommand DefaultLinksAdd
•
To restore these links using the web interface,
you must re-create them manually. See
the
Creating and editing links
section for
instructions on how to do this.

Automatically created links
Whenever a new subzone or zone is created,
links are automatically created as follows:

Along with the pre-configured default links this
ensures that, by default, any new subzone or
zone has connectivity to all other subzones and
zones. You may rename, delete and amend any
of these default links. See the
editing links
section for more information.
