Hybrid WAN and SD-WAN are two prominent networking solutions offering distinct advantages and drawbacks. While SD-WAN leverages Software-Defined Networking (SDN) to deliver services across diverse networks, Hybrid WAN establishes connections between geographically separate WANs using varied connection types. Let’s delve deeper into the pros and cons of each setup.

Hybrid WAN Overview

Hybrid WAN employs two distinct circuits to carry traffic between different locations. In the event of congestion or circuit failure, traffic is automatically rerouted to the secondary circuit. This setup offers flexibility by combining different network types, such as MPLS and internet circuits, enhancing network resilience and uptime. However, challenges like underutilized bandwidth and potential performance issues in public broadband links exist.

Pros of Hybrid WAN:

1. Cost-effective provision of 5G, LTE, and broadband internet, reducing overall bandwidth costs.

2. Flexible bandwidth utilization through traffic steering policies, enhancing network performance.

3. Improved reliability with diverse access methodologies like fiber, coax broadband, LTE, and 5G.

4. Efficient traffic management with path selection for optimal WAN circuit performance.

Cons of Hybrid WAN:

1. Underutilized bandwidth due to inactive circuits, limiting traffic distribution efficiency.

2. Potential for unreliable performance and congestion issues in public broadband links.

3. Limited visibility and analytics for troubleshooting application performance problems.

SD-WAN Overview

SD-WAN, a virtual WAN architecture, allows organizations to utilize various transport services like MPLS, broadband, and LTE for application access. Unlike traditional WAN architectures, SD-WAN employs centralized traffic management for secure and intelligent routing across the WAN, supporting on-premise, private, public cloud, and SaaS services.

Pros of SD-WAN:

1. Direct cloud access at remote branches, facilitating the migration of services like contact centers to the cloud.

2. Enhanced security with encrypted data tunnels and additional firewall devices.

3. Prioritization of critical traffic for optimal routing, reducing packet loss and latency.

4. Automated monitoring and centralized traffic management for increased productivity and ease of use.

Cons of SD-WAN:

1. Lack of true QoS provision for voice services.

2. Varied vendors and technical expertise requirements may hinder implementation.

3. Additional security measures may be necessary beyond built-in SD-WAN functions.

Choosing Between Hybrid WAN and SD-WAN

While both solutions aim to enhance WAN flexibility and agility, SD-WAN stands out for its direct cloud access, improved security, and automated management features. While Hybrid WAN may serve as a transitional step towards SD-WAN, the latter remains the preferred choice for future-proof networking solutions.
