PERFORMANCE ANALYSIS OF A MULTI-SUBNET VLAN-BASED NETWORK WITH INTER-VLAN ROUTING

the structured design and implementation of a hierarchical enterprise-style network, emphasizing the configuration of Virtual Local Area Networks (VLANs), inter-VLAN routing, and the analysis of network performance metrics. Students will configure VLANs across multiple switches, implement a router-on-a-stick architecture to enable communication between subnets, and validate connectivity using diagnostic and monitoring commands.
The practice extends beyond basic configuration to include segmentation for scalability and security, static routing for interconnectivity, and performance evaluation under simulated congestion conditions. By combining theoretical principles from the OSI and TCP/IP models with practical implementation, students will be able to critically evaluate the relationship between network design choices and measurable performance indicators such as delay, throughput, and packet loss.

分层企业级网络的结构化设计与实现，重点围绕虚拟局域网（Virtual Local Area Networks，VLANs）配置、跨VLAN路由以及网络性能指标分析展开。学员将在多台交换机上完成VLAN配置，部署单臂路由（router-on-a-stick）架构以实现子网间通信，并通过诊断与监控命令验证连通性。
本实践不局限于基础配置范畴，还涵盖面向可扩展性与安全性的网络分段、用于实现网络互联的静态路由，以及模拟拥塞场景下的性能评估工作。通过将开放系统互连参考模型（OSI）与传输控制协议/互联网协议（TCP/IP）模型的理论原理与实践操作相结合，学员能够批判性地评估网络设计方案与延迟、吞吐量、丢包率等可量化性能指标之间的关联关系。
