In this thesis , research has been carried on in several aspects such as network structure of voip , protocol layers of voip , signaling control protocols and the lan voip system based on sip 并设计实现了具有sip用户代理功能的voip终端设备,利用该设备在局域网中构建voip实验系统,从工程上探讨和验证voip网络理论及实时传输协议对于语音数据传输的保障作用。
Based on these analyses , a more understandable structure of usb was established . secondly , the usb device controller framework was established based on the usb device controller function requirements on clock extracting , protocol layer and data management 其次,针对usb设备控制器的功能要求,从时钟提取、事件检测、协议层、数据处理层通信等方面对其进行了结构设计和详细设计。
In the third chapter , we provide a system framework and protocol layer . we design two models : corporation model between different message entities and object - orient authentication model . we also describe how to apply web service in this system 第三章提出了系统的框架,提供了系统架构,协议层次,各个消息实体之间的协作模型,面向对象的论证控制模型,介绍了webservice在系统中的应用。
Based on 3gpp release ' 99 standard , the system control soft of the project is written for the three protocol layers mentioned above . the implement tools are the real time multi - tasking operating system , psos , and specification description language , sdl 课题的系统控制软件部分,是根据3gpprelease ' 99标准,以psos实时多任务操作系统为平台,利用规格描述语言? sdl语言对上述三个协议层进行软件编制。
Idip is an architecture supporting automated response to intrusions and is organized into two primary protocol layers : the idip application layer and the idip message layer . after depicting idip application layer , this paper primarily discuss a solution to idip message layer Idip组织为两个基本协议层: idip应用层和idip消息层,在介绍了idip应用层之后,本文主要探讨了一种idip消息层的设计方案。
The problems encountered on the process of design and implementation is discussed . based on ericsson bluetooth module rok 101 007 , i have implemented four core protocol layers ( hci , l2cap , sdp , rfcomm ) and two profiles ( lap , dunp ) , in c language under linux 在我的课题中利用爱立信的蓝牙模块rok101007在linux下用c语言实现了蓝牙协议栈的hci 、 l2cap 、 sdp 、 rfcomm这四层核心协议以及局域网访问( lap )和拨号上网( dunp )两个profile 。
But the internet communication is manifold diverse application combinations communicating on diverse mediums . that is to say , when users security requirement spans protocol layers , how to offer a universal security mechanism on internet becomes a problem to solve 而internet传输往往是多种不同的应用组合在不同的媒介上传输,也就是说,当用户的安全需求跨越了协议层的时候,如何提供一种internet上通用的安全机制成为了一个需要解决的问题。
Based on 3gpp standard , the author analyzed and researched the higher protocol layers of radio interface in wcdma , including radio resource control layer ( rrc ) , medium access control layer ( mac ) and radio link control layer ( rlc ) , in which , the rlc is emphasis 依据3gpp协议,作者对wcdma空中接口的高层协议部分进行了分析和研究,包括无线资源控制层( rrc层) 、媒体接入控制层( mac层)和无线链路控制层( rlc层) ,其中,对rlc层进行了重点研究。
The paper traverses web service technology . analyzes each protocol layers of it as well as its run time mechanism . and prospects its application foreground . the features of the paper are as follows : 1 , hlspn is used in the analysis of web service runtime mechanism , which analyzes its runtime course more clearly 本文详细研究了webservice技术,剖析了其各协议层,分析了其运行机制,并展望了其应用前景。本文的特色和创新之处在于: 1 、把hlspn运用到webservice运行机制分析中,更清晰地剖析了其运行过程。
