Packet - switched network 封包交換網(wǎng)絡
It is the unit in which information ( a message ) is transferred in a packet - switching network 它是分組交換網(wǎng)絡中信息(即報文)傳遞的單位。
17 what is a major advantage of circuit - switched networks over packet - switched networks 題目的意思是說從線路交換轉變?yōu)榘粨Q網(wǎng)絡的好處是什么?
In these networks , the data is transmitted in labeled cells , frames , or packets through a packet - switched network 在這些網(wǎng)路中,資料以標記的細胞,訊框或封包中經(jīng)過一個分封交換的網(wǎng)路被傳輸。
Use of packet - switched network can be charged according to the volume of data transferred and not to any notion of time spent online 在使用分組交換網(wǎng)絡時,可以按照傳輸?shù)臄?shù)據(jù)量(而非在線時間)收費。
Active networks represent a quantum step in the evolution of packet - switched network by providing a programmable network interface in network nodes 主動式網(wǎng)絡技術提出了可編程的網(wǎng)絡體系結構的思想,標志著分組交換網(wǎng)絡設計思想的飛躍。
Packet - switched networks were developed to overcome the expense of public circuit - switched networks and to provide a more cost - effective wan technology 分封交換網(wǎng)路被發(fā)展用來克服昂貴的公眾電路交換網(wǎng)路并提供一種較有成本效益的廣域網(wǎng)路技術。
From the above figure , we can see the original structure remains unchanged and the new packet - switched network is formed by adding a packet control unit ( pcu ) to the bss part 圖1gprs網(wǎng)絡結構從網(wǎng)絡結構圖可以看到,原有的網(wǎng)絡結構保持不變,只是在bss部分增加了分組控制單元( pcu ) ,新建了一個分組網(wǎng)絡。
A packet-switched network is a digital communications network that groups all transmitted data, irrespective of content, type, or structure into suitably sized blocks, called packets. The network over which packets are transmitted is a shared network which routes each packet independently from all others and allocates transmission resources as needed.
