5.1.1 Dual Route Path Protection and Unidirectional
Path Switched Ring (UPSR)
The XDM-100 supports highly efficient advanced rings over meshes that provide
inherent protection in the event of a traffic-affecting circuitry or link failure. In this
mode, the protection paradigm is a self-healing path-protection scheme.
Path protection is supported by all aggregate and tributary I/O modules, and
VC/STS trail protection may be selected from any two SIM/SAM interfaces. This
flexibility enables the XDM-100 to integrate with other network nodes and provides
end-to-end network path protection regardless of the network’s topology. This
integrated path protection capability enables operators to smoothly integrate the
XDM-100 into existing networks.
Path protection switching operates automatically in the XDM-100 and does not
require any operator intervention or path recalculation. In other words, each card
performs its own switching. The result is an exceptionally fast switch to protection,
which is performed in less than 50 ms.
