The Benefits of a Hybrid Wide Area Network

As businesses continue to expand their operations across various locations, the need for a reliable and efficient wide area network (WAN) becomes paramount. A hybrid wide area network combines the advantages of both traditional WAN technologies and the agility of software-defined networking (SD-WAN). This innovative approach offers numerous benefits that can revolutionize the way businesses connect and communicate.

Improved Network Performance

One of the key advantages of a hybrid WAN is improved network performance. By utilizing multiple connectivity options, such as MPLS, broadband, and LTE, businesses can balance network traffic and optimize performance. Mission-critical applications can be prioritized and routed through dedicated MPLS connections to ensure low latency and high reliability. Non-critical traffic, on the other hand, can be seamlessly routed through less expensive broadband connections, resulting in significant cost savings without compromising performance.

Additionally, a hybrid WAN allows for dynamic path selection, where the network can choose the most efficient and reliable route in real-time. This eliminates the risk of bottlenecks and congestion, ensuring smooth and uninterrupted network performance. By leveraging the benefits of both dedicated and public connections, businesses can achieve a highly resilient and high-performing network infrastructure.

Enhanced Security

Security is a top priority for any business, and a hybrid WAN offers enhanced security features compared to traditional WAN solutions. With the use of advanced encryption technologies, businesses can secure their data while it is in transit between different locations. This ensures that sensitive information remains protected from unauthorized access or interception.

In addition to encryption, a hybrid WAN also incorporates robust security policies and firewalls. These measures provide a defense against threats such as malware, ransomware, and distributed denial-of-service (DDoS) attacks. By deploying security measures at both the network perimeter and individual branch locations, businesses can create a secure and resilient network infrastructure.

Cost Efficiency

Cost efficiency is an important consideration for businesses of all sizes. Traditional WAN solutions, such as MPLS, can be costly to implement and maintain, especially for organizations with multiple branch locations. However, a hybrid WAN allows businesses to leverage less expensive connectivity options, such as broadband or LTE, without compromising on performance.

By intelligently routing network traffic through the most cost-effective connections, businesses can significantly reduce their WAN expenses. This is particularly beneficial for organizations with remote or branch offices, as they can leverage local internet service providers rather than relying solely on expensive dedicated circuits. The cost savings achieved through a hybrid WAN can be redirected towards other business initiatives, driving innovation and growth.

Choosing the Right Hybrid WAN Solution

When selecting a hybrid WAN solution, it is important to consider several factors to ensure it meets the specific needs of your business. By evaluating these factors, you can make an informed decision and implement a solution that optimizes your network performance, security, and scalability.

Understanding Bandwidth Requirements

One of the first considerations when choosing a hybrid WAN solution is understanding your bandwidth requirements. Assess your current and future data transfer needs to determine the appropriate bandwidth capacity. Consider factors such as the number of users, types of applications, and data-intensive tasks. An accurate assessment will help you select a solution that can handle your network traffic without bottlenecks or congestion.

Work with a reputable service provider who can help analyze your bandwidth requirements and recommend the most suitable connectivity options. This partnership will ensure that your hybrid WAN solution aligns with your business goals and growth plans.

Evaluating Network Compatibility

Before implementing a hybrid WAN, evaluate the compatibility of your existing network infrastructure. Determine whether your current network equipment, such as routers and switches, can support the hybrid WAN solution. If not, you may need to upgrade or replace certain components to ensure seamless integration.

In addition to hardware compatibility, consider the compatibility of your network management tools and software. The hybrid WAN solution should integrate seamlessly with your existing network management systems to ensure efficient monitoring, troubleshooting, and configuration.

Considering Scalability and Flexibility

Scalability and flexibility are crucial factors to consider when choosing a hybrid WAN solution. As your business grows and evolves, your network requirements will also change. Look for a solution that can easily scale to accommodate your future needs without significant disruptions or additional hardware investments.

In addition to scalability, flexibility is important for businesses that require agility in their network operations. Consider a solution that allows for dynamic path selection, which can automatically adapt to changes in network conditions. This flexibility enables efficient and optimized routing, ensuring consistent network performance even in dynamic environments.

Implementing a Hybrid WAN

Implementing a hybrid WAN involves a systematic approach to ensure a smooth and successful transition. By following these key steps, businesses can minimize disruptions and optimize the benefits of their hybrid WAN solution.

Assessing Current Network Infrastructure

Before implementing a hybrid WAN, assess your current network infrastructure to identify any areas that may need improvement or modification. Perform a thorough audit of your network equipment, including routers, switches, and firewalls. Identify any outdated or end-of-life components that may hinder the performance of your hybrid WAN.

Additionally, evaluate your current network topology and ensure it aligns with your business requirements. Consider factors such as network redundancy, traffic flow, and security. This assessment will help identify any gaps or weaknesses that need to be addressed during the implementation process.

Selecting the Appropriate Technologies

When implementing a hybrid WAN, it is important to select the appropriate technologies that align with your business needs and goals. Consider the different connectivity options available, such as MPLS, broadband, and LTE. Each option offers unique advantages and should be evaluated based on factors such as cost, performance, and reliability.

Work closely with your service provider to select the most suitable technologies for your specific requirements. Consider factors such as service-level agreements (SLAs), network coverage, and compatibility with your existing network infrastructure.

Planning for a Smooth Transition

A smooth transition is crucial when implementing a hybrid WAN to minimize disruptions to your business operations. Develop a detailed implementation plan that outlines key milestones, timelines, and responsibilities. Identify any potential risks and develop contingency plans to mitigate them.

Communicate the implementation plan to all relevant stakeholders and provide training or resources to ensure a seamless transition. Regularly monitor the implementation progress and address any issues or challenges that arise promptly.

Optimizing Performance and Security in a Hybrid WAN

Optimizing performance and security is essential for businesses utilizing a hybrid WAN. By implementing the following strategies, businesses can maximize the benefits of their hybrid WAN solution.

Utilizing Traffic Shaping and Priority Queuing

Traffic shaping and priority queuing allow businesses to allocate network resources effectively and prioritize critical applications or services. By implementing these techniques, businesses can ensure that bandwidth is allocated according to their specific needs.

Traffic shaping involves controlling the flow of network traffic to optimize performance and minimize congestion. By setting bandwidth limits and prioritizing certain traffic types, businesses can prevent non-critical applications from impacting mission-critical services.
