They can range from simple point - to - point voice communication to multi - party , multi - channel and multi - media applications 通讯方式不仅是简单的点对点话音通讯，亦包括多方通讯、多讯道及多媒体应用。
Outside of the spp simple point - to - point package that i adopted for peer - to - peer communication , the p2p application doesn t consist of many classes 除了对等通信采用的spp （简单点到点）包之外， p2p应用程序不包含很多类。
I have three simple points that when you read the words you will be tempted to ignore them because they do not seem to be profound , insightful or challenging 想先警告你，我会提出三点，但你很容易会忽略它们，因为它们看来并不重要，也没有洞见或挑战性。
It is a technology that is turning user - unfriendly phone functions , such as the creation of a teleconference with inside and outside lines , into simple point - and - click operations 它是一种把用户不友好的电话功能（如用内外线开电话会议）变成简单的点击鼠标操作的技术。
The simplest point of view is to consider instruction processing as consisting of two steps : the cpu reads ( fetches ) instructions from memory one at a time , and executes each instruction 最简单的划分就是将指令过程分为两个步骤： cpu每次从内存中取一条指令，然后执行每条指令。
The open - loop system is normally used in simple point - to - point , or positioning systems , although improvements in technology have made it possible to install the system in contouring systems as well 虽然技术的进步已使等值线系统安装在系统中成为可能，但开环系统通常只在简单的点对点或配置系统中应用。
Its implement depends on tunneling mechanism , l2tp tunneling integrates the virtues of l2f and pptp . the identity - authentication mechanism and key management of l2tp adopt the way of simple point to point tunneling validate and pre - shared secret , at all it can ’ t extend . the l2tp lacks of the corresponding compartmentalizeof trust - relation and level , it can ’ t offer enough protection of privacy 其实现主要依靠隧道技术,其中的l2tp技术结合了l2f和pptp的优点,身份认证机制和密钥管理采用简单点到点的隧道验证和预共享秘密的方法,根本无法扩展,也缺乏相应的信任关系和层次划分,不能提供更好的隐私保护。
The increasing of single channel capacities and evolution of optical networks topology , from simple point - to - point to intelligent optical networks , call for strict demands to optical filters . in this paper , the crucial technologies of optical filters such as interleaver , optical digital filter , fused biconical taper all - wave coupler as well as polarization - pump combiner have been studied experimentally and theoretically , which include : 1 . a new process , cascaded fbt ( fused biconical taper ) with precise control as well as strict interference arm length difference , is proposed for the first time to our knowledge 单信道速率不断提高以及网络拓扑由单一的点对点传输向可上下载的环网和可动态选择波长路由的智能型格形光网络演进，对光滤波器的常规性能指标、时域特性和动态可调谐特性提出了更加苛刻的要求，鉴于此，本论文全面研究了全光纤熔锥型奇偶交错滤波技术、数字光滤波技术、基于g - t全通滤波器的奇偶交错滤波技术以及熔锥型全波耦合器和偏振泵浦合波器。
