Table
5-1: Traffic protection schemes
Protection scheme
Network topology/
configuration
Main benefits
Traffic protection
1+1 UPSR/path
protection
Mesh, ring, point-to-point
♦
Dedicated performance monitoring-based
protection for any VC-12/3/4 or E1/DS-3/STS-
3c and concatenated traffic
♦
Better service reliability
SNCP (single and
dual node
interconnections)
Mesh, ring, point-to-point
♦
Better reliability and network resilience as the
XDM-100 handles multiple failures over mesh
topologies
Two-fiber
MS-SPRing/BLSR
Ring (within mesh topology)
♦
Better bandwidth utilization in case of uniform
or adjacent traffic patterns
♦
Multiring closure within the same XDM-100
(path protection, MS-SPRing/BLSR and UPSR)
in mesh topologies, together with low-order E1
connectivity, improve network efficiency and
reduce floorspace and costs compared to
common protection schemes
RSTP Multiring
♦
Bandwidth efficiency
