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.
Some advantages of transforming WAN edge capabilities include:
Wide Area Network (WAN) edge solutions are crucial for connecting multiple remote branch offices to a central location and the internet. They are designed to optimize network performance, provide security, and ensure reliable connectivity. There are various types of WAN edge solutions, each offering unique features and capabilities. Here are a few:
WAN edge solutions are crucial in connecting remote branch offices and ensuring reliable and secure connectivity. Each type of solution has its own unique features and advantages, enabling organizations to choose the one that best fits their requirements and network environment. From traditional routers to SD-WAN and edge compute, organizations have a wide range of options to optimize their WAN infrastructure.
WAN Edge Solutions is an advanced networking approach that focuses on optimizing Wide Area Network (WAN) connectivity, improving performance, and enhancing security for distributed enterprises. It leverages software-defined networking (SDN) technologies and utilizes a centralized management platform to provide numerous benefits to organizations with geographically dispersed locations. Here is an overview of how WAN Edge Solutions work:
• SD-WAN Architecture: WAN Edge Solutions typically utilize a software-defined wide area network (SD-WAN) architecture that separates the network control plane from the underlying infrastructure. This allows for centralized management and control across multiple WAN connections and integrates easily with existing network infrastructures.
• Intelligent Path Selection: With WAN Edge Solutions, software intelligence is applied to automatic and dynamic path selection for data transmission. It analyzes multiple WAN links and applications' requirements to determine the most appropriate path based on factors like latency, packet loss, and bandwidth availability. This leads to optimal performance and efficient utilization of available bandwidth.
• Traffic Prioritization: WAN Edge Solutions support Quality of Service (QoS) policies, enabling organizations to prioritize critical applications and ensure their performance over less important traffic. This ensures that real-time applications like voice and video conferencing are not adversely affected by bandwidth-intensive activities.
• Security and Encryption: Strong security measures are integral to WAN Edge Solutions. Traffic is often encrypted, using protocols like IPsec, to protect data privacy and meet regulatory compliance requirements. Traffic inspection capabilities enable security policies to be enforced consistently across the entire network.
• Centralized Management and Configuration: WAN Edge Solutions provide a centralized management platform that simplifies and streamlines network administration. IT teams can configure and monitor network devices, apply policies globally, and gain real-time visibility into network performance and application usage.
• Cloud Readiness: Since WAN Edge Solutions enhance connectivity, they are well-suited for organizations adopting cloud services. They can optimize connectivity to cloud providers, direct traffic to the closest entry point, and provide secure links between branches and cloud resources.
• Continuous Monitoring and Analysis: WAN Edge Solutions include monitoring and analytics capabilities to provide insights into network performance and application usage. Real-time monitoring allows IT teams to proactively identify and address any issues or bottlenecks that may arise.
WAN Edge Solutions are designed to deliver secure, high-performance, and cost-effective WAN connectivity and management for geographically dispersed organizations. By leveraging SDN technologies and centralizing control, organizations can enhance their network performance, optimize resource utilization, ensure data security, and prepare for cloud adoption.
WAN Edge solutions significantly enhance network security by integrating advanced threat protection features such as intrusion prevention systems, firewalls, and malware detection. These solutions also provide secure tunneling methods and encrypt data to protect it from unauthorized access during transit. By centralizing traffic management, WAN Edge can monitor and quickly respond to potential security breaches, reducing vulnerabilities in your network infrastructure.
What are the cost benefits of implementing WAN Edge?Implementing WAN Edge can lead to substantial cost savings by reducing dependency on expensive MPLS connections, leveraging more cost-effective broadband and LTE links. It also consolidates multiple networking and security functions into a single device or platform, which reduces hardware costs and simplifies management. Additionally, centralized management reduces operational expenses associated with maintaining and troubleshooting disparate systems.
How does WAN Edge enhance application performance?WAN Edge improves application performance through intelligent traffic routing and prioritization, ensuring that critical applications receive the necessary bandwidth. It provides capabilities like WAN optimization, caching, and application-aware routing, which reduce latency and improve response times. By continuously monitoring network conditions, WAN Edge can dynamically adjust traffic flows to avoid congestion, ensuring consistent performance for all users.
What are the main components of a WAN Edge solution?The main components of a WAN Edge solution include a centralized management console, edge devices such as routers and firewalls, and software-defined networking (SDN) controllers. These components work together to provide secure connectivity, traffic management, and application visibility. The centralized management console allows for unified policy enforcement and monitoring, while the edge devices handle local traffic processing and security functions.
How can WAN Edge support a hybrid cloud environment?WAN Edge supports a hybrid cloud environment by providing seamless connectivity between on-premises data centers and cloud services. It ensures secure and reliable connections through VPNs, direct cloud integrations, and software-defined WAN (SD-WAN) capabilities. This allows you to optimize traffic flows, securely extend your network to the cloud, and maintain consistent performance and security policies across all environments.
