【摘要】 针对目前嵌入式Internet(EI)技术中存在的问题,将VoIP技术中的SIP协议引入到现有的嵌入式Internet中来,在不影响原有体系结构的基础上,实现了SIP与原有模型的接口,并提出了一种基于SIP协议的嵌入式Internet定位模型(ESL),此模型解决了应用层命名问题,满足了用户不断增长的高级需求,尤其是在远程定位以及移动设备的访问上,更是具有突出优势,使嵌入式设备具有智能化和安全性的特点·更多还原

【Abstract】 SIP protocol is introduced into existing embedded Internet field to solve EI problems, which belongs to VoIP technology. The interface between SIP and original model is thus implemented on existing architecture. A new embedded Internet location model based on SIP protocol, i.e. ESL model, is also presented to name application layers and meet the increasingly growing high-layer demands. In particular ESL model gains an advantage over others that it enables EI systems to be intelligent with security in remote locating process and access of mobile devices.更多还原
