Connectivity Advisory

Resilient Connectivity Advisory

CorePath Network Group helps IT and finance teams define connectivity requirements, compare qualified carriers and service providers, review pricing and commercial terms, and coordinate sourcing, provisioning dependencies, and implementation milestones.

Resilience Starts With Understanding Failure Domains

Connectivity resilience depends on more than ordering multiple circuits.

CorePath helps organizations review carrier dependencies, physical routes, building entrances, local loops, upstream infrastructure, bandwidth requirements, latency objectives, application dependencies, cloud connectivity, and recovery requirements.

Two providers do not automatically provide physical-path diversity. A resilient evaluation reviews the infrastructure behind each service before treating one circuit as protection for another.

What We Help With

• Connectivity requirements development
• Dedicated internet and Ethernet sourcing
• Dark fiber evaluation
• SD-WAN and transport comparison
• Carrier and physical-path diversity review
• Cloud and data center connectivity
• Disaster recovery connectivity planning
• Contract and SLA comparison
• Circuit provisioning coordination
• Telecom service inventory and billing review

Understanding the Connectivity Options

Each connectivity service type has distinct characteristics. Evaluating the right option requires reviewing your specific requirements, locations, application dependencies, and risk tolerance — not defaulting to a familiar provider or service.

Dedicated internet access, Ethernet transport, and private connectivity are different services. Bandwidth commitments, routing, latency objectives, service levels, and provider responsibilities depend on the specific service and contract.

Dark fiber provides access to an unlit fiber path. Equipment, optics, network operation, maintenance responsibilities, route availability, and commercial structure require separate evaluation.

SD-WAN is an overlay using one or more underlying connectivity services. Its performance and resilience depend on the transports beneath the overlay, provider configuration, policies, and failure domains. Reference: MEF 70.2 SD-WAN Service Attributes and Service Framework.

Carrier diversity and physical-path diversity are separate considerations. Review building entrances, conduit routes, local loops, carrier infrastructure, upstream dependencies, and common failure domains before treating services as diverse. For a detailed comparison, read our SD-WAN vs. Dedicated Fiber Guide.

Why Independent Connectivity Evaluation Matters

Carriers and service providers differ in network reach, building access, route availability, service levels, installation requirements, support models, and commercial terms.

CorePath compares qualified options through the same technical and commercial requirements. The evaluation focuses on fit, resilience, provider responsibilities, pricing, contract terms, and implementation dependencies.

For standard sourcing engagements, CorePath receives compensation from the selected provider or distribution partner after deployment. The client pays no direct advisory fee for this sourcing model and retains final authority over provider and contract decisions.

CorePath Network Group is not an MSP, carrier, network operator, or help desk. Selected providers remain responsible for network design implementation, service delivery, technical operations, monitoring, repair, SLAs, and ongoing support.

Common Connectivity Decisions We Help Evaluate

Who This Is For

• IT and infrastructure teams evaluating connectivity options or carrier changes
• Finance teams reviewing telecom costs, contracts, and recurring charges
• Organizations approaching a telecom contract renewal or expiration
• Businesses planning a new site, data center, or cloud connectivity path
• Teams managing multi-site or multi-carrier network environments
• Organizations reviewing disaster recovery connectivity requirements

Connectivity Advisory FAQ

What information is needed for a connectivity review?

A connectivity review should include your site locations, current carrier agreements, invoices, circuit inventory, bandwidth requirements, application dependencies, performance concerns, outage history, renewal dates, security requirements, growth plans, and recovery objectives. CorePath uses this information to define requirements and compare suitable provider and network options.

What is the difference between carrier diversity and physical-path diversity?

Carrier diversity means using more than one network provider. Physical path diversity means those connections enter the building, travel through conduits, use meet-me rooms, and reach upstream networks through separate physical routes. Two carriers might still share the same building entrance, conduit, fiber path, or upstream dependency. A resilient design should validate both carrier diversity and physical path diversity.

Does SD-WAN replace the underlying network connections?

No. SD-WAN manages traffic across existing connections, but the underlying circuits still provide network access. SD-WAN can improve application routing, visibility, failover, and policy control. It does not remove the need to evaluate carrier performance, bandwidth, physical diversity, service levels, and circuit reliability.

How is CorePath Network Group compensated?

For standard sourcing engagements, CorePath Network Group typically receives compensation from the selected provider or distribution partner after deployment. This structure generally allows clients to use CorePath’s sourcing support without a direct advisory fee. CorePath discloses the compensation structure before the client makes a provider decision.
