Udemy限免：如何将传统网络迁移到思科SDwan | Udemy Coupon | Udemy优惠码 | Udemy免费课程

Before migrating to Software-Defined Wide Area Network (SD-WAN), a thorough analysis of your existing network infrastructure is crucial. This analysis will help identify potential issues, optimize performance, and ensure a smooth transition to SD-WAN.

Key Areas to Analyze:

1. Network Topology:
   • Physical Topology: Understand the physical layout of your network, including the locations of routers, switches, and firewalls.
   • Logical Topology: Map out the logical connections between devices and the flow of data within your network.
2. Network Performance:
   • Bandwidth Utilization: Measure the amount of bandwidth consumed by different applications and services.
   • Latency: Evaluate the time it takes for data to travel between different points in your network.
   • Packet Loss: Determine the rate at which packets are lost during transmission.
3. Application Performance:
   • Application Usage: Identify the critical applications that rely on your network.
   • Performance Metrics: Measure the performance of these applications, such as response times and throughput.
4. Security Posture:
   • Security Controls: Assess the effectiveness of your existing security measures, including firewalls, intrusion detection systems, and VPNs.
   • Vulnerabilities: Identify potential security vulnerabilities in your network.
5. Infrastructure Assessment:
   • Hardware Compatibility: Ensure that your existing network devices are compatible with SD-WAN solutions.
   • Software Compatibility: Verify that your current network operating systems and applications are compatible with SD-WAN.
6. Cloud Connectivity:
   • Cloud Usage: Assess the extent to which your organization relies on cloud services.
   • Cloud Connectivity: Evaluate the current performance and reliability of your cloud connections.
