Protection and Redundancy

In today’s mission-critical broadband networks, a cut fiber optic cable means
upheaval. The fiber is essentially the lifeline to the network. Data loss due to cable
failure, node failure, port failure, disastrous switch failure, and even equipment
failure results in millions of dollars of lost revenue, as well as some very frustrated
users.
The XDM

®

-100 features proven redundancy mechanisms, ensuring complete

integrity of all traffic transfers. The system’s protection schemes comprise highly
reliable trail protection arrangements, as well as equipment duplication on all units.
The XDM-100 also provides protection for internal traffic paths. All traffic is fully
redundant within the system and is routed via separate traffic paths and hardware
units. In case of equipment or line failure, traffic protection switching takes 8-12 ms.
The system supports mesh and ring traffic protection and restoration mechanisms
that ensure traffic rerouting in the event of a major contingency. Carriers may define
their own major contingencies based on individual operating parameters. Traffic
restoration time is generally dependent on the network’s complexity and traffic load.

5.1 SDH/SONET Path/Circuit Protection

Schemes

The XDM-100 features path and circuit protection over ring and mesh topologies, as
follows:

♦

Bidirectional Path Switched Ring (BPSR) dual-route path protection 1+1
(route diversity) and Unidirectional Path Switched Ring (UPSR)

♦

Path protection over mesh and SubNetwork Connection Protection (SNCP)
(enhancing BPSR-over-mesh topologies)
