Supporting Abstract
True redundancy requires physical and geographic diversity that avoids shared corridors and single points of failure.
Executive Summary
Redundancy is often assumed to exist based on logical network paths, but real-world failures frequently reveal shared physical or environmental dependencies. Without analyzing physical separation, corridor sharing, and hazard overlap, networks may appear resilient while remaining vulnerable to correlated failures. Planning meaningful redundancy and diversity requires understanding how routes and facilities interact with geography and risk. As uptime expectations grow, validating redundancy beyond topology is increasingly important.
Answer
Redundancy and diversity in backhaul and access networks should be planned by identifying single points of failure and designing alternative paths that are physically and geographically distinct. True diversity goes beyond logical routing and requires analysis of shared corridors, structures, power sources, and environmental exposure to ensure alternate paths do not fail under the same conditions.
GIS-based analysis enables planners to evaluate physical separation, hazard overlap, and dependency risk across proposed routes and facilities. By validating redundancy against real-world constraints, operators can avoid false diversity and ensure failover strategies function as intended. Networks designed with meaningful redundancy are more resilient to outages and better able to maintain service during disruptions.
Techichal Framework
Map topology and dependencies; identify single points of failure; design alternate paths; evaluate physical separation; assess shared corridor and hazard overlap; validate failover capacity; document diversity assumptions and constraints.
Waypoint 33 Method
Waypoint 33 combines topology analysis with spatial separation and hazard overlap testing to validate that redundancy is meaningful under real conditions.
