Multiwan Use Cases

Why Use MultiWAN?

MultiWAN addresses critical network challenges by:

• Eliminating Single Points of Failure: MultiWAN is a system that uses multiple internet connections (such as broadband, fiber, cellular data) simultaneously. Even if one connection goes down, MultiWAN ensures that your internet continues.
• Optimizing Bandwidth Utilization: MultiWAN combines multiple internet connections, making data transfer faster and allowing more data to be sent at once.
• Improving Application Performance: MultiWAN uses more than one internet connection. It distributes traffic appropriately to speed up essential applications, so things run smoothly and latency is reduced.

Benefits of MultiWAN for Businesses

Various businesses can gain many benefits by using MultiWAN deployments:

• Increased Uptime and Business Continuity: In a multiWAN system, if one internet connection goes down, the other connection automatically starts. This ensures that work does not stop and important work continues.
• Enhanced Productivity: When the network is working well and reliable, employees can get more done because they can run applications faster and face fewer interruptions.
• Cost Optimization: Multi-WAN can provide cheap and fast internet by combining different internet connections, eliminating the need to rely on expensive internet connections.
• Improved User Experience: When the network is fast and has low latency, employees and customers get a better experience when using network resources.

How MultiWAN Improves Network Reliability

MultiWAN significantly improves network reliability:

• Failover and Redundancy: MultiWAN systems can automatically detect WAN connection failures and, if one connection goes down, can forward traffic to another connection, ensuring that the connection remains up.
• Intelligent Routing: MultiWAN solutions can route data appropriately based on network link status, application needs, and network conditions, improving performance and reducing issues.
• Proactive Monitoring: Many MultiWAN solutions have monitoring tools that show how the WAN links are performing WIth these tools, we can detect and resolve any issues before they occur.

MultiWAN for Load Balancing

Load balancing is a key feature of MultiWAN that distributes network traffic across multiple WAN connections improving performance and preventing congestion.

Scenario: Businesses that sell more online should create a website or app for their customers that is easy to use and works quickly.

Solution:

• MultiWAN is a type of network that uses more than one internet connection (such as fiber and broadband).
• Load balancing is configured to distribute traffic across these connections based on predefined rules.
• Web traffic is distributed between internet connections such as fiber and broadband, so that websites load faster and information is accessed faster.
• This ensures that even when there is a lot of traffic on the website, it works quickly, and customers get a good experience.

Technical Details	Implementation
WAN Interfaces	Ethernet interfaces (e.g., eth0, eth1) are designated as WAN links.
Traffic Distribution	Traffic is distributed evenly between available connections (e.g., 50%-50%).
Monitoring	A monitoring system (e.g., Lucy) checks configurations and policies.
Load Balancing Rules	Traffic is routed based on protocol, source/destination, and port.

MultiWAN for Failover and Redundancy

If your main internet connection stops working, a system called failover automatically switches traffic to another internet connection. This way, your work doesn't stop.

Scenario: Treating doctors rely on the network to obtain vital information about patients and communicate between their hospitals.

Solution:

• MultiWAN is used for main and backup internet connections (such as fiber and cellular).
• If fiber internet goes down, cellular internet will automatically start.
• Notification emails are set up to alert you about failure events.
• This ensures that communication between patient data and facilities continues even if the fiber fails.

Technical Details	Implementation
WAN Interfaces	Multiple internet connections (e.g., fiber and LTE) are configured.
Failover Mechanism	If fiber fails, traffic is rerouted to LTE automatically.
Notifications	Email alerts notify IT teams about failures.
Traffic Routing	Predefined policies manage failover scenarios.

Use Cases for Different Industries

MultiWAN provides useful solutions across various industries:

• Retail: To support online operations, stock tracking, and point of sale (POS) systems.
• Healthcare: Maintaining access to patient records, enabling telemedicine, and supporting critical medical devices means keeping patient records secure, treating patients remotely, and keeping essential medical equipment functioning properly.
• Education: Online education requires good internet access so that students and teachers can easily communicate with each other and study from home.
• Finance: Making financial data available securely and reliably, supporting online banking, and enabling smooth transactions.

MultiWAN for Remote Offices and Branch Locations

MultiWAN is very useful for remote offices and branches, where network connectivity may be less good or expensive.

Scenario: Companies that have many offices in different places should create a well-functioning network for their employees. So that each employee can work and each office can communicate comfortably with the main office.

Solution:

• In each office, a MultiWAN network will be set up. This network will use cost-effective internet connections (such as broadband and cellular data).
• This provides additional space and even if one connection is down, the branch offices can remain connected.
• MultiWAN makes better use of bandwidth, ensuring that there is sufficient capacity for applications and communications across office branches.

Technical Details	Implementation
WAN Interfaces	To continue even if one internet connection goes down, a MultiWAN setup should be maintained in every office..
Traffic Optimization	Smart routing makes the internet run better.
Failover Mechanism	If one connection goes down, traffic goes to the other connection.

MultiWAN for Cloud Connectivity

MultiWAN provides additional connectivity for applications and services hosted in the cloud and can improve cloud connectivity by increasing speed.

Scenario: The company uses applications and services on the Internet for its daily work.

Solution:

• MultiWAN is used to connect a company’s computer network to the networks of companies providing cloud services. This connection uses more than one path.
• Even if one connection is lost, cloud-based applications continue to be used.
• MultiWAN can improve performance by intelligently sending traffic to the cloud, reducing latency, and improving application response times.

Technical Details	Implementation
WAN Interfaces	Multiple WAN links with cloud services
Failover Mechanism	Care is taken to ensure that there are no problems in using cloud applications.
Traffic Optimization	Routes traffic dynamically based on link performance.

Performance Improvements with MultiWAN

MultiWAN improves network speed and performance by:

• Bandwidth Aggregation: Combining the bandwidth of multiple WAN connections results in increased throughput and faster data transfer speeds.
• Traffic Optimization: MultiWAN can intelligently route traffic based on application requirements and network conditions, ensuring that critical applications receive the necessary bandwidth and priority.
• Reduced Latency: By optimizing traffic flow and selecting the best-performing WAN connection, MultiWAN can reduce latency and improve application responsiveness.
