SD-WAN network equipment ports and connected cables

Enterprise networking / SD-WAN

Enterprise networking and SD-WAN

Connect headquarters, campuses, branches, server rooms and cloud resources in one verifiable map of sites, circuits, access policy and operating ownership.

Sites / paths / policy

Map the sites before choosing the path.

Headquarters, campuses, branches and offices may use different circuits to reach data centre and cloud resources. The key questions are which path an application takes, where policy applies and who can explain the map after change.

Enterprise networking and SD-WAN architecture and delivery flow
The diagram explains sites, circuits, policy and implementation steps; actual circuits, equipment and cutover boundaries require a site review.

Before a path is chosen

What still needs checking after connectivity is in place?

SD-WAN does not replace switching, routing, wireless or cabling. Applications, connectivity, security and operating conditions must be defined within one implementation scope.

ApplicationsAccess relationships for critical systems, office collaboration and cloud resources.
Connectivity conditionsExisting circuits, site access, equipment capability and cutover boundaries.
Security boundaryPolicy, inspection points, exceptions and ownership.
FailoverRepresentative traffic, rollback paths and validation records.
Operations handoverTopology, configuration, change and troubleshooting records.
Enterprise network integration and site delivery environment
Site conditions determine how the design is delivered and whether handover records remain useful.

From site to handover

Site inventory, implementation and handover.

Inventory sites, switching and routing foundations, wireless and cabling dependencies together with application paths and security policy. Drive pilots, cutover, validation and handover around the real environment.

Inventory

Bring sites and the current state together

Review headquarters, campuses, offices, branches, server rooms and cloud resources together with switching, routing, wireless, cabling and existing links.

Implementation

Organise connectivity and policy by relationship

Design the pilot around application paths, security boundaries and operations ownership, then confirm change order and rollback scope.

Validation and handover

Leave an operating baseline behind

Validate paths and cutover with representative access, then hand over topology, configuration, tests and change records.

Start with the real network

Bring the existing network to the table.

Start with a site change, circuit adjustment, cloud-resource access need or network issue under investigation to define the networking scope and next step.
