摘要： 在分析了动态虚拟子网的构建和扩展特点的基础上,提出了一种新型网关设计方案,解决了移动上网中PC的配置和管理问题,并在Linux 2.4内核下实现了这一方案。对比DHCP协议,该方案可以保留主机原有配置,达到全透明使用的目的。试验测试表明,系统达到了全透明的设计目标,并获得了较高的吞吐率和较好的稳定性。

Abstract: Based on the analysis of the features of dynamic virtual sub-network’s building and extension, this paper gives a new scheme of the gateway to resolve the problems of configuration and management of locomotive PC in mobile network. This scheme is implemented in Linux 2.4 kernel. Comparing with DHCP, the new implementation can keep original configuration of locomotive PC unchanged, and carry full-transparent point. Experiment results show that the goal of the scheme has been achieved completely, and also, high throughput and good stability have been obtained.
