mplsLpsConfigProtectionType

The protection architecture type of the protection domain.
This object represents both the bridge type, which can be
either a permanent bridge (1+1) or a selector bridge (1:1);
and the switching scheme, which can be either unidirectional
or bidirectional.
              
1+1
In the 1+1 protection scheme, a fully dedicated protection
path is allocated.  Data traffic is copied and fed at the
source to both the working path and the protection path.
The traffic on the working path and protection path is
transmitted simultaneously to the sink of the protection
domain, where selection between the working path and the
protection path is performed.
              
1:1
In the 1:1 protection scheme, a protection path is allocated
to protect against a defect, failure, or degradation on the
working path.  In normal conditions, data traffic is
transmitted over the working path, while the protection path
functions in the idle state.  If there is a defect on the
working path or a specific administrative request,
traffic is switched to the protection path.
              
bidirectional
In the bidirectional protection scheme, both directions
will be switched simultaneously even if the fault applies
to only one direction of the path.
              
unidirectional
In the unidirectional protection scheme, protection switching
will be performed independently for each direction of a
bidirectional transport path.
              
This object may not be modified if the associated
mplsLpsConfigRowStatus object is equal to active(1).
