What is SD-WAN?
Software-Defined Wide Area Networking (SD-WAN) is a modern networking solution that intelligently routes business internet traffic across multiple connections, such as fiber, cable, 5G/LTE, and cloud services. SD-WAN continuously monitors network performance and automatically selects the best available path to ensure optimal application performance, reliability, and uptime.
Unlike traditional networks that rely on a single internet connection, SD-WAN provides redundancy, failover protection, centralized management, and improved visibility into network performance across multiple locations.
Managed SD-WAN Solutions
Keep your business connected with intelligent SD-WAN solutions, internet failover, network monitoring, and proactive network management. TTI helps organizations maximize uptime, improve application performance, and maintain secure connectivity across offices, remote workers, and cloud environments.
SD-WAN Reduces Networking Costs Without Sacrificing Reliability
SD-WAN enables businesses to securely connect branch offices, remote employees, and cloud applications using virtually any available internet connection. By leveraging broadband, fiber, cable, and wireless services, organizations can significantly reduce the cost of traditional MPLS networks while maintaining enterprise-level reliability, performance, and business continuity.
Why Businesses Use SD-WAN
Modern businesses depend on cloud applications, remote workers, VoIP phone systems, and reliable internet connectivity. Even a brief outage can impact productivity, customer service, and revenue.
Internet Failover
Automatically switches to a secondary internet connection if the primary connection fails, minimizing downtime and keeping employees connected.
Multi-Location Connectivity
Connect headquarters, branch offices, remote workers, and cloud applications through a centralized network architecture.
Improved Application Performance
Prioritizes critical business applications such as Microsoft 365, VoIP phone systems, video conferencing, CRM platforms, and cloud services.
Business Continuity
Maintains connectivity during ISP outages, network disruptions, and other unexpected events.
Centralized Network Management
Monitor and manage all business locations from a single dashboard, simplifying troubleshooting and reducing IT complexity.
Enhanced Security
Securely connects offices, users, and cloud applications while providing visibility into network traffic and performance.

Case Study
The Challenge
A healthcare client operating 7 corporate locations faced unsustainable operating expenses supporting 150 IP phones and workstations. Their legacy network architecture relied on traditional MPLS circuits, driving up overhead costs to an average of $2,300.00 per month, per location.
The legacy infrastructure severely restricted business operational capacity due to rigid bandwidth caps:
• Primary Links: Confined to 40 Mbps dedicated fiber at two core hubs, and just 20 Mbps fiber across the five remaining branch offices.
• Secondary Links: Fragmented backup circuits utilizing standard consumer-tier Comcast and Verizon FiOS lines.
The TTI Managed Solution
TTI engineered and deployed a high-performance, fully resilient SD-WAN architecture, entirely replacing the costly MPLS network:
-
✓
High-Capacity Routing & Connectivity: We upgraded primary hub locations with Gigabit-capable enterprise routers configured for Dual-WAN Failover via high-speed, business-class FiOS and Comcast tiers. The five branch sites were provisioned with 400 Mbps primary service backed by a 100 Mbps secondary connection.
-
✓
Cellular Integration: Branch sites were equipped with integrated multi-carrier cellular SIM hardware managed directly by TTI, establishing a robust tertiary layer of network redundancy.
-
✓
Peplink SpeedFusion Bonding: Deploying Peplink Balance 20X endpoints allowed TTI to bond distinct internet paths into a single cohesive pipe. This advanced SpeedFusion deployment guarantees unbreakable, zero-interruption failover—completely eliminating dropped voice calls or active remote session timeouts during primary ISP disruptions.
-
✓
Secure vMPLS Overlay: To maintain seamless, encrypted inter-office data transfers and internal voice routing, TTI deployed a secure virtual MPLS (vMPLS) overlay network across all seven nodes.

Full Capital ROI
- • Substantial OpEx Reduction: Average recurring costs dropped from $2,300.00 down to a flat $850.00 per month, per location. This predictable flat fee includes all high-speed broadband connections, automated failover management, and core cloud communication services.
- • Rapid Return on Investment: The client achieved full ROI in under 6 months. This calculation comprehensively covers all newly deployed enterprise edge routers alongside 85 high-end, 27-button cloud desktop phones.
- • Performance & Compliance Gains: Modernizing the network architecture systematically eliminated packet drops and jitter. Communications are now fully optimized for crystal-clear voice clarity, secure against ISP downtime, and perfectly aligned with strict HIPAA compliance mandates.
SD-WAN is WAN VirtualizationIn the same way server virtualization abstracts the underlying physical hardware from the logical virtual servers that run on it, WAN virtualization allows a logical WAN connection (either to the Internet or between branch offices) to utilize multiple underlying connectivity technologies—such as xDSL, MPLS, cellular, and fiber—simultaneously. This connectivity is seamlessly presented to users and applications as a single, direct connection to the Internet or a secure site-to-site connection. |

SD-WAN is IntelligentSD-WAN enabled networks are capable of continuously monitoring WAN health and connection quality, then automatically utilizing those measurements to make intelligent routing decisions for your real-time application traffic.
Best of all, once configured, all internal traffic management happens natively. Your network is dynamically governed by the automated software-defined rules set directly on the device—requiring absolutely zero human interaction or manual IT troubleshooting. |

SD-WAN is Secure VPNBy utilizing encrypted VPN tunnels, branch offices gain secure, seamless local network access to critical cloud resources. SD-WAN dramatically increases the speed and affordability of these branch office networks by combining the total bandwidth of multiple disparate connections into a single cohesive, logical WAN pipe. Additionally, SD-WAN provides the intelligence to safely offload public Internet traffic at the network edge, maximizing overall performance and reducing unnecessary traffic strain sent through your core VPN. |
