Service plane can support the access of application to network core resources and the operation of the third part service developer. So the development of new service is quickened. Service plane also helps to coordinate the trust and interconnection of different management domains and optical networks with different switching mechanisms.

业务功能不同粒度的划分和分布，可以提高业务运行效率并实现业务的定制和组合；业务平面可以支持应用对网络核心资源的访问，以及第三方业务开发商的运作，从而加快新业务的开发；业务平面对协调不同管理域和不同交换结构的光网络的互信、互通也会有积极的影响。

Three procedures are introduced as client application roams, redelivery of subscribe message, the deliveries of Fetch and Replay Message. Not only it extends the framework, but also does the roaming transparency of client application is implemented, which supports the mobility of client application among different nodes multiple.

在客户应用移动时，通过引入订阅消息的重新发送、Fetch消息的传递和Replay消息的传递3个过程，实现对分布式订阅/通知框架的扩充，实现客户应用移动的透明性，支持客户应用在不同的网络连接节点之间的迁移，具有良好的可适应性。

As a kind of simple and effective network management protocol, SNMP is widely used and supported. Currently it has become the most important network management system structure.

作为一种简单而有效的网络管理协议， SNMP 得到了广泛的支持与应用，已经成为当今最重要的网络管理体系结构。

More and more practical data in sensor network、communication、Internet flow analysis and Web log etc, are transported from teledata sources. Therefore, we need to construct the middleware of distributed query processing for data streams to support above application.P2P technique is used to build a huge distributed network for the processing of large number of information by internet terminals.

现有的数据流的研究主要为集中式的流数据系统，而数据流的本质是分布式的，越来越多如传感器网络、数据通讯、Internet流量分析和Web日志等的大量数据都来自不同的远程数据源，因此，需要构建分布式数据流查询处理的中间件以支持上述各种应用。P2P技术利用互联网的终端机来建立一个庞大的分布式计算网络，并对迅速涌出的大量信息进行处理。

When constructing large scale wireless area networks, the traditional network techniques become unaccommodated due to lack of flexible extension and fast transition support.

传统的无线区域网络在进行大规模应用时受制于网络灵活扩展和对快速移动的支持。

ARM-based microcontrollers because of cost-effective, extensive third-party support and the good universalness is bound to lead to the development and a very wide application, terminal equipment used in recent years and PDA is hot subjects, and the ZigBee appearring near two years is a wireless communications technology, which is IEEE802.15.4-based application software protocols involved in networking, security, and in home automation, industrial building automation control systems which are widely used.

基于ARM的微控制器由于高性价比、广泛的第三方支持和良好的通用性必然导致发展和应用非常广泛，近年应用于各种终端设备和PDA是热点研究对象，而ZigBee技术是近两年出现的无线通信技术，它是以IEEE802.15.4技术为基础的一组涉及网络、安全、应用的软件协议，在家居自动化、楼宇自动化工业监控系统得到广泛的应用。

Therefore, there is a possibility for improving the performance of non-real-time data traffic while still meeting the QoS of service requirement for real-time CBR traffic. The DOCSIS is established as the primary HFC network data communication standard. The intended service allows transparent bi-directional transfer of Internet Protocol traffic between the Cable Modem Termination System in cable system headend and Cable Modem in customer locations with significantly high data rate.

DOCSIS HFC网络的宽带性能使得传输高质量的实时音视频数据成为可能，实时可变比特率视频业务是宽带HFC网络的主要应用之一，实时VBR视频业务具有严格的延时和延时抖动要求，然而当前的DOCSIS HFC网络只能提供高速Internet接入，只支持有限的服务质量保证，现有的协议和方法不适合上行传输实时VBR视频业务。

Traditional best-effort service model in IP networks has brought great success to the Internet, if controlled and provisioned appropriately, this model will still be able to satisfy the majority of popular applications in the future.

IP网络传统的尽力而为服务模型已经使Internet获得了巨大的成功，如果能对网络采用恰当的控制机制，这种服务模型仍然可以在将来支持广泛的应用类型。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
