What is SDN and how is it different from a traditional network?

SDN (Software Defined Networking) separates the control plane from the data plane: a centralized controller programs the entire network in software instead of configuring each switch individually through the CLI. With SDN you provision a VLAN, a security policy or a new segment in minutes via API, not in weeks of manual tickets. BITS deploys SDN with Cisco ACI, VMware NSX, Arista CloudVision and Juniper Apstra for data center and campus environments in Mexico.

How much time do I save by automating my network with SDN?

Network teams that take 10-15 days to provision a new VLAN (ticket → design → maintenance window → manual execution → validation) drop to 5-15 minutes with SDN. Policy changes that used to take a full day now apply in seconds. Typical savings are 70-90% of operational time and 95% fewer human configuration errors.

Is SDN only for data centers, or does it work for campus too?

Both. Data center SDN (ACI, NSX, Arista CloudVision) automates leaf-spine fabric, micro-segmentation and multi-cloud connectivity. Campus SDN (Cisco DNA Center, Aruba CX Fabric, Juniper Mist) automates wired plus wireless, identity-based segmentation and AI-driven troubleshooting. BITS designs both scenarios with the same assessment, pilot and phased-migration methodology.

Which SDN platforms does BITS deploy?

Data center: Cisco ACI, VMware NSX-T/NSX-V, Arista CloudVision (CVP), Juniper Apstra and Cumulus Linux. Campus: Cisco DNA Center / Catalyst SD-Access, Aruba CX Fabric Composer, Juniper Mist AI, Extreme Fabric Connect. Orchestration: Ansible, Terraform, Python/REST APIs across any vendor. We choose the stack based on your current hardware, the use case and the team that will operate the network.

Do I need to replace all my network hardware to adopt SDN?

Not necessarily. Many modern switches (Cisco Nexus 9K, Catalyst 9K, Arista 7050/7280, Juniper QFX, Aruba CX) are already SDN-ready and only need a license and controller. For older hardware we propose coexistence: a new SDN fabric in the data center, legacy CLI-managed segments, and a phased migration as equipment is refreshed — no big-bang cutover.

What does the SDN migration process look like without taking production down?

Five phases: 1) Assessment of the current network (topology, VLANs, ACLs, policies, dependencies). 2) Target SDN design with your team. 3) Controlled pilot in a lab pod or pilot site. 4) Phased migration with small windows and validated rollback. 5) Operations automation (playbooks, network GitOps pipelines, dashboards). We run in parallel with your existing network the entire time.

Does SDN integrate with my Zero Trust security and micro-segmentation?

Yes — in fact it's the natural enabler. SDN allows micro-segmentation by workload, identity or tag (not just IP), end-to-end Zero Trust policy enforcement and automatic propagation of firewall rules across data center, campus, branch offices and cloud. We integrate with Cisco TrustSec, NSX Distributed Firewall, Fortinet, Palo Alto and ZTNA providers depending on your stack.

What support and operations does BITS provide after deploying SDN?

A 24/7 NOC monitoring fabric health, streaming telemetry, predictive alerts and API-driven change management. Automated change management through network GitOps pipelines (validation, dry-run, approval, push). A help desk for your internal network engineers, monthly capacity reports and an enterprise SLA with service credits if we miss it.

SDN — Software-defined networking that provisions in minutes, not weeks

Software Defined Networking for data center and campus with Cisco ACI, VMware NSX, Arista CloudVision or Juniper Apstra. Automate VLANs, micro-segmentation and Zero Trust policies via API — orchestrated and operated 24/7 by BITS from Mexico, with no endless maintenance windows and no CLI errors.

Isometric illustration of SDN: a central controller orchestrating a leaf-spine switch fabric, micro-segmentation, real-time telemetry, APIs and Zero Trust policies automatically deployed across the data center.

THE PAIN OF MANUAL CLI NETWORKING

Two weeks to create a VLAN. One morning with SDN.

A corporation with 47 switches across 3 sites took 12 business days to provision a new VLAN — ticket, design, review, maintenance window, switch-by-switch execution and validation. Every change carried the risk of a CLI typo. With BITS SDN on Cisco ACI plus Ansible we automated the fabric: VLANs are now pushed in 9 minutes via API, with dry-run, GitOps approval and automatic rollback — zero manual errors.

The real cost of sticking with manual CLI

Changes that take days, typos that bring down entire segments, dependence on a handful of senior engineers and zero configuration traceability.

The cost of adopting SDN the wrong way

Buying ACI or NSX licenses without a fabric design, a GitOps pipeline or training — it ends up being CLI with an expensive dashboard.
