Will hold the post of mottled bamboo from the doctor that invites major socially, website day visits a quantity to achieve hundreds IP, the server space discharge of hire is insufficient, visit rate is very slow, do not have method, be forced to buy oneself independent server, half an year went, visit quantity increases ceaselessly, increased a server again act against one's will, invite the relevant personnel such as net canal, technology, customer service at the same time, and at this moment the income that my website did not bring one article money for me, still threw several yuan instead.

从社会上聘请专业的医师来任斑竹，网站日访问量达到数百个IP，租用的服务器空间流量不够，访问速度非常慢，没办法，只好购买自己的独立服务器，半年过去了，访问量不断增加，不得已又增加了一台服务器，同时聘请网管、技术、客服等相关人员，而这时我的网站没有为我带来一文钱的收入，相反还投入了数万余元。

Firstly, the thesis introduced the development of VOD, the background and meaning of the program, then the author introduced the associated technology, mainly including the feature of multimedia, video compression technology and the protocols SCTP and RTP. Considering the ambulant of host , fluctuation of bandwidth,high error rate data in wireless networks ,the author proposed some QoS strategy in the wireless networks such as RTP/SCTP protocol stack , connection control of the server, two buffers in the client end point.,TFC congestion control algorithms ,etc. Based these strategies, the team members gives the software and hardware solution of the wireless video-on-demand system and gives the main modules design of the software system. The system adopted the C/S structure including two parts: server and client ,using the Mpeg-2 which is apporiate for networks as the supported format. The thesis emphatically researches on the video-serving module of the server and the sink module, player module of client.

本文首先介绍了视频点播系统的发展现状、课题的研究背景和意义；接着对课题的相关技术进行概述主要包括了多媒体特点，压缩技术，传输协议SCTP以及RTP；针对无线环境的节点移动性，带宽波动性，数据错误率高等三大特点，作者研究设计了无线环境下的QoS策略：RTP/SCTP协议栈，服务器准入控制机制，客户端双缓冲区，TFRC拥塞控制机制等；在这些策略的基础上设计了系统的软硬件解决方案，并对软件体系结构的主要模块进行了设计，整个视频点播系统采用C/S结构，由服务器，客户端2个部分组成，使用适合网络传输的流媒体格式Mpeg-2作为系统支持的格式，文中重点研究了服务器的视频服务模块以及客户端的接收模块和播放器模块，并利用线程池技术对系统进行实现。

Application of media gateway technology, launched sobe First Class Service for multimedia conversion equipment - media server, thus the birth of a number of unique personality-related devices, such as using a variety of video and audio IO interface board video and audio media server for a wide range of media format conversion of documents between the high-performance media server.

应用媒体网关技术，索贝推出了一类用于多媒体转换服务的设备――媒体服务器，由此催生出一些具有独特个性的相关设备，如采用多种视音频IO接口板卡的视音频媒体服务器、用于多种媒体格式之间高效转换的文件媒体服务器。

Being put to use self-similar model in the access process of network service can guide the design of the clustered network servers, especially for the strategy of single entry point of the cluster.

将自相似过程用于网络服务器的访问过程，指导机群网络服务器，特别是服务器单一登录点系统的设计，有助于提高整个系统的性能。

The low strategy of business affects undesirable server site stability: Low is done not have any wrong, but the server does not stabilize those who bring stationmaster is a deathblow, work laboriously when the quantity comes up, the server often appears such and such problem, make stationmaster depress.

不良服务器商的低价战略影响站点稳定性：低价并没有任何的错，但服务器不稳定带给站长的是致命的打击，辛辛劳苦等到量上来，服务器老是出现这样那样的问题，使站长灰心丧气。

In order to improve the systemic extensibility, stability and high effective service, a systemic model of directory service that had hiberarchy was presented in this paper. The general directory server would be acted as the marginal directory server. It made catalogue by using LDAP protocol and made management through diaphysis directory server.

为了提高系统的扩展性、稳定性和服务的高效性，提出了将普通目录服务器作为边缘目录服务器利用LDAP协议进行重新编目，以骨干目录服务器对其进行管理的层次结构目录服务系统模型。

In this part, it discusses the function model of Process Enactor, and the architecture of the Enactor. Based on the above discussing, it describes the client/server design and client/server model of Enactor. And then, it describes the primary protocol of client/server, client process design, server process design and the interfaces design of network communication. At last, it discusses the integration of tools and activities.

这里首先描述了过程运作环境的功能模型，在此基础上提出了运作环境的体系结构，然后给出了运作环境的客户/服务器设计和总的客户/服务器模型，随后描述了客户机进程的设计、服务器进程的设计以及网络通讯接口的设计等技术问题，最后讨论了工具与活动的集成问题。

Unlike the common hot standby mode with different software between master server and slave server, in this system, master server and slave server are equipotent. It confirmed the identities of master server and slave server according to start-up sequence, and it also has the following functions: synchronous renewal of the configuration files, synchronous storage of data, heartbeat detection, fault diagnosis and server switch.

与一般的在主从服务器端安装不同软件的双机热备方式不同，本系统的主从服务器具有对等性，根据主从采集服务器的启动顺序来确定主从机的身份，并且具有配置文件的同步更新、数据的同步存储、心跳检测、故障诊断与双机切换等功能。

Since the step that is most computationally expensive and causes computational imbalance between clients and server in the SSL handshake protocol is the decryption computation of the server,we show that a client balanced secret exchange algorithm can be used to speedup SSL session initialization and undertake the previous computation tasks of server's decryption.

由于在SSL握手协议中最耗费计算资源和造成客户端与服务器端计算不平衡的步骤是服务器端解密运算，提出了客户端平衡的密钥交换算法，用来加速SSL会话的初始化和承担服务器端的解密的预运算。
