DESCRIPTION
"The architectural mode of the Protection group. This can
either be 1+1, 1:1, 1:n.
1+1
In the 1+1 protection scheme, a fully dedicated
protection entity is allocated. Data traffic is copied
and fed at the source to both the working and the
protection entities. The traffic on the working and the
protection entities is transmitted simultaneously to
the sink of the protection domain, where selection
between the working and protection entities is performed
1:1
In the 1:1 scheme, a protection path is allocated to
protect against a defect, failure, or a degradation in a
working path. In normal conditions, data traffic is
transmitted over the working entity, while the
protection entity functions in the idle state. If there
is a defect on the working entity or a specific
administrative request, traffic is switched to the
protection entity.
1:n
In case of 1:n linear protection, one protection entity
is allocated to protect n working entities. The protection
entity might not have sufficient resources to protect all the
working entities that may be affected by fault conditions at a
specific time. In this case, in order to guaranteed
protection, the protection entity should support enough
capacity and bandwidth to protect any of the n working
entities."
