第三层交换由于能解决局域网在性能、安全和控制等方面的许多问题,因此成了局域网中许多区域(包括核心和服务器集中点)的关键组件。然而,在一些网络区域,该项技术的使用效果并不十分显著,尤其是在桌面连接方面。本文详细介绍了此项技术以及如何部署第三层交换才能获得最大效率。 为了充分认识第三层交换,有必要对目前使用的大多数网络体系结构的分层模型进行分析。图1所示 Layer 3 switching is a key component of many areas of the LAN, including core and server hubs, because it addresses many of the issues in LAN performance, security, and control. However, in some network areas, the effect of this technology is not very significant, especially in the desktop connection. This article details this technique and how to deploy Layer 3 switching for maximum efficiency. In order to fully understand the third layer of exchange, it is necessary to analyze the hierarchical model of most network architectures currently in use. Figure 1 shows
