嵌入式LINUX中套接字组件的设计与实现

The Design and Realization of the SOCKET Component in Embedded LINUX

随着嵌入式硬件性能的迅速提高,如何解决嵌入式产品基于网络分布式异构环境下的良好协同和有效的应用开发成为实现良好的、具有网络功能的嵌入式产品的关键问题。通过对4.4BSD的TCP/IP套接字内核研究发现,在支持网络功能的嵌入式系统中,对TCP/IP套接字的功能模块进行封装,使接口与外部进行交互,并使用CORBA技术将其应用于网络异构环境之中,能实现在分布式开发环境中、异构环境下的良好协同以及灵活的网络通信功能。

With the development of the hardware performance, how to resolve the problem of the good coordination and well development in the heterogeneous network are the key problem of the supported-network embedded system. By analysis of 4.4 BSD TCP/IP Socket, the function model of socket in the embedded system supportednetwork function is packaged. Middle-ware and component can be well applied in the network communication by CORBA. The supported-network function can communicate in the distributed system through the interface.
