Description

Introduction of SD-WAN Implementation

Software-Defined Wide Area Network (SD-WAN) provides organizations with a more agile, cost-effective, and secure method of managing their wide area networks. SD-WAN decouples the network control plane from the physical hardware and enables centralized management and dynamic routing based on real-time network conditions. This course focuses on the best practices for implementing SD-WAN, including configuration strategies, integration considerations, and tips for maximizing security and performance in your network.

Prerequisites

• Basic understanding of networking concepts and WAN technologies.
• Familiarity with routing protocols (e.g., BGP, OSPF) and VPNs.
• Experience with basic network configuration, security practices, and cloud technologies.
