Phone networks are now abandoning the old circuit-switching technology in favor of something called Internet Protocol( IP) packet-switching technologies, which make more efficient use of the transmission " pipe " or network.
电话网络正在摈弃旧的线路交换技术，采用一种称为互联网协议（ IP ）分组交换的技术。这种技术可以更加有效地利用传输管道或网络。
For example, a phone company moving the information on a CD-ROM from New York to Los Angeles over a traditional switched telephone network pays about $27 in transmission costs. Over an IP network the cost to the operator is about $2.
例如，如果一家公司想把一张只读光盘（ CD-ROM ）上的信息从纽约传输到洛杉矶，采用传统的交换电话网络要花 27美元，而采用 IP 网络，付给经营公司的费用仅为 2美元。
The huge difference in cost is due to the fact that circuit-switching technology used in a traditional telephone network opens and maintains a line whenever a call is made, regardless of whether someone is sending a huge data file or making a simple phone call.
费用方面的巨大差别源于以下事实：只要有人呼叫，无论用户在传送一个大容量数据文件还是在打一个简单的电话，传统电话网络采用的线路交换技术都要打开线路，并保持线路畅通。
