摘要
介绍了一种家庭网络主网网关的设计和研制,外部网络通过它能实现对家庭内部网络的接入控制。以家庭网络的Internet接入为重点,阐释了接入设备的研制,论述了主网网关的软件设计,分析并解决了有关进程间通信的两个关键性问题,最后简要说明了通过PSTN和IEEE 802.11b网络接入家庭网络的软硬件设计及实现。本系统已在春兰集团等单位实际应用,经进一步改造又是一种嵌入式系统家庭网络的教学实验设备。
This paper introduces the design and development of a main-gateway in Home Network. The principal function of the main-gateway is to actualize the external network access of home network. The device accessing Internet in home network is particularly emphasized. The software design of the main-gateway is described and the solutions of two key problems about inter-process communication are analyzed. Moreover, the actualization of the device accessing PSTN and IEEE 802. 11b WLAN is also briefly mentioned. The system has been applied by Chunlan Group and regarded as a demo system on home network in embedded system for teaching and experiment purpose.
