From each town in the County Street, all 一、 选题背景、研究意义及文献综述 1、 选题背景 未来信息网络建设正迅猛发展，以数据分组交换为基础的IP技术向传统的电路交换技术发起了巨大的挑战，这一技术的巨大变革，为我国的信息产业提供了难得的发展机遇，同时也是严峻的考验。作为中国信息产业三大网络之一的中国有线电视网因其具有宽带、高速和连接干家万户的网络优势，十分适合这一新技术的普及和应用，将是构建我国信息高速公路较理想的通道。电通信系统的作用，是将产生消息的信源信息发送到一个或多个目的地。一般情况下，通信系统可以使用图1.1所示的功能方框图进行示。愿望所产生的信息可以使声音(语音源)、图像(影像源)，或以某些特殊语言如英语、日语、德语、法语等写成的纯文本。产生信息的任何一个信源，都有一个基本的特征，即它的输出是以概率参量描述的，也就是说一个信源的输出是不确定的，否则信息传输就是去了意义。 2、 研究意义 为全球信息产业正在发生一场从传统网络到现代信息网络的重大变革。这场变革的标志就是第一代低速因特网(IP网)向第二代因特网(宽带IP网)的转变，以窄带交换电话业务为主要标志的传统电信网已成为制约信息产业发展的瓶颈，以宽带包交换多媒体业务主要标志的第二代因特网应运而生。 3、 文献综述 有线电视网络已不再是只能传输多套模拟电视节目的单向网络，随着社会需求的不断增长和科学技术的飞速发展，有线电视网络正在逐步演变成具有综合信息传输交换能力、能够提供多功能服务的宽带交互式多媒体网络，它将融合在信息高速公路中，成为未来信息网络不可缺少的组成部分，可以肯定，作为信息传输的一种有效手段，有线电视网络必将长期存在并得到不断的发展。IP技术是一个古老而又年轻的技术，源于60年代中晚期美国国防部的ARPANET研究及组网过程，其主small, and per capita occupies less, and financial strength weak of fundamental reasons.

From each town in the County Street, all 要设计理念是原来相对庞大数据块分割成很小的数据包(Packet)再将每个数据包标记上源和目的信息，并使众多标记的不同源和目的地址的数据包，能够通过一个公共的网络正确地传到目的地，即IP技术是采用无缝连接，分组/数据包交换和路由寻址的技术。 宽带IP网就是一个基于互联网的IP网与宽带特性相结合的网络。它在运行如语音、图像等实时性业务是能保证QOS服务质量，各种宽带多媒体业务可以直接在宽带IP网上运行，是一个真正的综合业务网。宽带IP技术采用最先进的千兆IP线速路由器/交换机或ATM多业务交换机与IP技术相结合，能与ATM/SDH/DWDM宽带传输平台充分互联，特别是IP优化光网络技术，能够承载和交换包括语音、视频实时性等各种数据信息，并将其接入公用用户。 IP网络以其先进的技术克服传统IP网络不能保证服务质量(QOS)的缺点，形成一个真正意义上的交互式开放性网络，保证与Internet国际、国内出口的无缝连接，与现有SDH/ATM网络的无缝连接。 二、 研究的基本内容，拟解决的主要问题 本需要实现: 有线电视网络是一种采用同轴电缆、光缆或者微波等媒介进行传输，并在一定的用户中分配或交换声音、图像、数据及其他信号，能够为用户提供多套电视节目乃至各种信息服务的电视网络体系。宽带IP网络是目前实现语音、图像、数据等业务综合的最佳方案，也是未来网络的基石。 宽带IP网络设计对超负载因数、阻塞/无阻塞、QOS的考虑:额负载链路和阻塞的硬件体系结构经常造成拥塞和容量问题，而应用超负荷大都是由网络缺乏信息服务质量保证(QOS)造成的。不能完全理解这些问题造成的影响，就不可能设计优化的网络。 服务器系统设计 集成服务器交换包括服务器阵列、服务器簇、后置数据库、Web主机和服务器备份网络。这种拓扑结构要求服务器到服务器，客户机到服务器两种连接都具有很宽的带宽。 ..
