SD-WAN Technology’s High Availability and Security

In today's digital era, the demand for network availability and security in businesses is on the rise. SD-WAN (Software-Defined Wide Area Network), as an advanced networking technology, not only enhances location-based availability but also provides outstanding security, making enterprise networks more robust and reliable.

Key to Improved Availability: Applications of SD-WAN

1. Multi-Path Redundancy Strategy

Global SD-WAN implements routing through a multi-path redundancy strategy, providing alternate connection paths during severe line failures to ensure continuous business operations. By blending different types of WANs, such as 4G/LTE and fiber optics, various routes can be flexibly configured. Each location, user, or resource can have the correct available connectivity, with an appropriate amount of elasticity configured. For instance, during a power outage, global SD-WAN routers automatically switch traffic to a secondary connection, ensuring users remain unaware of network issues or connection failures.

2. MPLS Dual-Path Connections

In crucial business locations like data centers, global SD-WAN can establish dual-path connections using MPLS. Large office line connections may utilize MPLS, while temporary teams can leverage 4G/LTE. Despite different connection configurations, all sites are managed by the same security policies and routing rules, ensuring consistency across the entire network. By extracting maximum value from foundational WAN resources, businesses can achieve optimal Return on Investment (ROI).

Exceptional Security of SD-WAN

Compared to traditional WAN networks like MPLS, global SD-WAN excels in security. Its centralized management control effectively monitors and manages the performance of the entire network stack. Through software-defined wide-area network performance and event monitoring, anomalies, compromised user accounts, and threats can be promptly identified.

1. Enhanced Quality of Experience (QoE)

International SD-WAN solutions introduce new network configuration features, significantly enhancing the Quality of Experience (QoE) for specific applications. By dynamically assembling virtual networks, international SD-WAN establishes secure connections based on business isolation, supporting encrypted data transmission with international and national cryptographic algorithms.

2. Authentication and Security Policies

New international SD-WAN devices require authentication before joining the hybrid network, ensuring only legitimate devices can access the enterprise network. Security policies are strengthened, allowing sensitive traffic to be isolated from other flows using unique encryption keys. Moreover, at the network layer, the optimal combination of links and gateways is selected based on application and user security standards and performance requirements, further enhancing data security and performance.

In conclusion, international SD-WAN technology brings significant advantages to enterprise networks by improving availability and strengthening security. By fully leveraging international SD-WAN's capabilities, businesses can achieve a flexible, reliable, and secure network environment, driving business development and innovation.
