Eliminate Single Points of Failure With True Network Path Diversity
Network path diversity uses physically separate circuits, carriers, and last-mile infrastructure to ensure that no single failure — cable cut, carrier outage, equipment failure, or building ingress failure — takes down all connectivity to a location.
What RLM Delivers on Network Path Diversity
Most 'redundant' networks aren't truly diverse — both circuits enter the building through the same conduit, use the same carrier backbone, or share the same last-mile infrastructure. RLM evaluates true path diversity and designs the carrier and physical architecture that provides genuine resilience.
How We Approach Network Path Diversity
Our network advisory runs from discovery and market evaluation through vendor selection and post-deployment optimization — scoped to the Network Path Diversity decision in front of you.
Diversity Assessment
We assess the actual diversity of your existing redundant circuits — tracing physical routes, identifying shared infrastructure (shared conduit, shared carrier backbone, shared building entry), and documenting the failure modes that a single event could trigger.
Diversity Architecture Design
We design the diversity architecture — different last-mile technologies, separate carrier backbones, diverse building entry points, and separate equipment — required to achieve the resilience level your SLA commitments demand.
Carrier & Technology Mix
True diversity often requires mixing technologies — fiber from one carrier, fixed wireless or cable from another — to avoid shared infrastructure risk. We design the technology and carrier mix that provides genuine independence.
Testing & Validation
Diversity must be tested — not assumed. We design the diversity validation approach including planned maintenance failover tests, physical circuit tracing, and documentation of the failure isolation boundary.
Network Path Diversity Evaluation Criteria
The questions below are the ones that decide whether a Network Path Diversity investment pays back — and the ones vendors are least eager to answer.
Last-Mile Independence
Two circuits from different carriers that converge at the same last-mile infrastructure (neighborhood node, building entrance conduit) are not truly diverse. Evaluate last-mile infrastructure independence, not just carrier diversity.
Building Entry Points
Single building entry points create a single point of failure regardless of carrier diversity. Evaluate whether your building has or can provision dual entry points on opposite sides of the structure.
Carrier Backbone Overlap
Many carriers share backbone infrastructure through peering relationships or physical co-location. Evaluate whether your 'diverse' carriers share backbone infrastructure in ways that create common failure risk.
Geographic Risk
For critical locations, evaluate geographic risk — natural disaster zones, flood plains, areas with poor utility infrastructure — that affect the reliability of all connectivity providers in a region simultaneously.
Failover Speed
True diversity requires automatic, fast failover when a primary path fails. Evaluate the failover mechanism — BGP failover, SD-WAN path switching, or router failover — and the speed at which traffic redirects to the backup path.
Cost of True Diversity
Genuine path diversity typically costs more than notional redundancy. Evaluate the cost of true diversity against the business impact of a connectivity failure at each location — the economics vary significantly by application criticality.
"RLM gave us an objective view of our network options that no single vendor could. We replaced aging MPLS across 40 locations and came in 28% under our original budget."
The benchmark comes first. Without a baseline, “savings” is just a number a vendor gave you.
Where This Matters Most
Sector-specific considerations we see repeatedly in advanced networking engagements.
