摘要 随着无线网络的不断发展，有线网络和无线网络的融合必将成为一种趋势，新型的网络设备的产生也将成为一种必然，有线无线一体化交换机就是这种设想的实现。接口管理作为交换机设计中的重要软件组成部分，它在交换机中抽象底层的硬件驱动，定义完备的接口，给上层管理提供接口，是交换机软件开发的主要内容，对于交换机的软硬件的管理和交换性能具有十分重要的意义。 本文以某公司的AX7000有线无线一体化企业级交换机项目为背景，深入研究了Cisco、Juniper等公司的接口管理设计模式，提出了自己的设计方案。基于交换机的PORT和VLAN实现交换机的二层接口、三层接口、协议接口以及各种特性接口的定义，运用Port和VLAN之间的关系使接口之间相关联。实现虚拟网卡驱动以支持三层接口，完成交换机网关功能。添加ARP和路由信息学习管理模块，保证网络安全和数据转发的高效、畅通。最终根据定义的接口实现命令行的配置功能。 关键： Abstract With the continuous development of wireless networks, the amalgamation of cable and wireless networks will definitely become a trend, and it is inevitable that a late-model network apparatus, such as the Wire and Wireless Integration Switch, will come into being. As an important software components of the Integration Switch, Interface management which abstracts the underlying hardware drive, defines the whole Interface and provides interface for the superior management, has great significance for the management of Integration Switch’s softwarehardware and its performance. This thesis, via a AX7000 Wire and Wireless integration Enterprise-class Switch project and thoroughly studying on Cisco’s, Juniper’s and some other company’s Interface Management design pattern, puts forward my own design pattern in which I educed the definability of Ethernet Interface, Layer 3 Interface, Protocol Interface and a variety of some special interface and identified their relations via the Port and VLAN of intreface, and achieved the virtual network card driving which gives support for layer 3 interface, and fulfilled the function of interface’s gateway. And by appending ARP and Management Module of Router information learning, so that we can ensure network’s safety and its efficiency and stabilization of data transmition and finally achieve the configuration’s function of command-line according to its definition of interface.
