课程名称：如何将传统网络迁移到Cisco SD-WAN 课程概述：在迁移到软件定义广域网（SD-WAN）之前，对现有网络基础设施进行全面分析至关重要。这项分析将有助于识别潜在问题，优化性能，并确保平稳过渡至SD-WAN。 关键分析领域： 1. 网络拓扑： - 物理拓扑：了解网络的物理布局，包括路由器、交换机和防火墙的位置。 - 逻辑拓扑：绘制设备之间的逻辑连接及数据在网络中的流动。 2. 网络性能： - 带宽利用率：测量不同应用和服务所消耗的带宽量。 - 延迟：评估数据在网络不同点之间传输所需的时间。 - 数据包丢失：确定在传输过程中丢失的数据包率。 3. 应用性能： - 应用使用：识别依赖于网络的关键应用。 - 性能指标：测量这些应用的性能，如响应时间和吞吐量。 4. 安全态势： - 安全控制：评估现有安全措施（包括防火墙、入侵检测系统和VPN）的有效性。 - 漏洞：识别网络中潜在的安全漏洞。 5. 基础设施评估： - 硬件兼容性：确保现有网络设备与SD-WAN解决方案兼容。 - 软件兼容性：验证当前的网络操作系统和应用程序与SD-WAN的兼容性。 6. 云连接： - 云使用：评估组织对云服务的依赖程度。 - 云连接：评估当前的云连接性能和可靠性。 本课程将为参与者提供系统的方法和工具，以支持传统网络向SD-WAN的顺利迁移。
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: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.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.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.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.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.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.
