WAN Edge Solutions refers to a category of networking technologies designed to optimize and secure Wide Area Network (WAN) connectivity for organizations. These solutions address the challenges of connecting geographically distributed sites and users and provide efficient data transmission across the WAN. Key aspects of WAN Edge Solutions include:
• Software-Defined WAN (SD-WAN) solutions
• Virtual Private Network (VPN) technologies
• WAN optimization techniques
• Traffic prioritization and Quality of Service (QoS) mechanisms
• Intelligent routing and path selection
• Network security features like firewalls and intrusion prevention systems
By incorporating these solutions, WAN Edge Solutions enable organizations to enhance network performance, increase security, reduce costs, and improve overall user experience across their wide area networks.
Current WAN edge technologies are increasingly influenced by SD-WAN (software-defined wide area network) technologies. SD-WAN identifies business-critical applications and directs them over the most efficient route of the WAN.
WANs and SD-WANs vary in the following ways:
WAN |
SD-WAN |
|
Application Performance |
WAN architecture drives the traffic from the network edge via data centers for security checks before sending it to the network. This causes delays and issues with cloud performance. |
SD-WAN identifies and prioritizes critical application traffic. The system can detect where to send each app’s traffic, and distributes it to the closest cloud inspection service. |
Connectivity |
Transports the traffic over MPLS (multiprotocol label switching) from branch routers to data centers. |
Uses broadband and internet services, providing faster connectivity and extra bandwidth. |
Management and Visibility |
WAN architecture is typically siloed, which can be complicated when you need to orchestrate multiple licenses and vendors. |
Uses a unified management approach, with centralized policy creation and visibility. |
Security |
Typically uses a VPN (virtual private network) to create a secure tunnel and protect the data. |
Integrates advanced security mechanisms such as IPS (intrusion detection systems). |
Costs |
WAN infrastructure requires investment in hardware and it is generally expensive to update or expand the network. |
SD-WANs don’t require investing in hardware to scale or expand the network. Additionally, they use low-cost internet to transport information, thus they are cheaper than MPLS. |
Transforming the WAN (wide area network) edge by adding SD-WAN (software-defined WAN) functionality can improve productivity, simplify WAN operations and allow for better digital transformation and transition to the cloud.
