无论是新建一个网络,还是对网络进行扩展,除了网络带宽以外,下列三方面因素都是不可忽视的:一、为关键数据应用保留网络资源的能力;二、支持新的交互式实时多媒体应用的能力;三、为电话技术与数据网络集成留有余地。在早期网络应用中,应用只需利用终端接入主机,使用10Mbps LAN中的一小部分带宽。而当前的网络支持大范围的不同应用类型,包括客户机/服务器、文件和打印服务、Intranet和Web访问以及数据库复制等。而且台式机也能以100Mbps或更高的速率生成突发的网络业务流量,进行交互式应用的用户可能受到其它网络应用的影响,接受较长的网络延时。而交互
Whether it is building a new network or expanding the network, in addition to the network bandwidth, the following three factors can not be ignored: First, the ability to retain network resources for critical data applications; Second, to support the new interactive real-time multimedia applications Ability; Third, leave room for telephone technology and data network integration. In early web applications, the application simply tapped into the host to use a fraction of the bandwidth in the 10Mbps LAN. The current network supports a wide range of different types of applications, including client / server, file and print services, intranet and web access, and database replication. And desktops can generate bursty network traffic at 100 Mbps or higher, and users of interactive applications may be affected by other network applications for longer network latency. Interaction
