Circuit Switching and PacketSwitching There are two basic types of switching techniques: circuit switchingandmessageswitching.Incircuitswitching,atotalpathofconnected linesissetupfromtheorigintothedestinationatthetimethecall ismade,andthepathremainsallocatedtothesource-destinationpair(whetherusedornot)untilitisrelea...
内容提示: 电路交换和分组交换(Circuit switching and packet switching) Circuit switching and packet switching Circuit switching technology is rarely used in data service networks, mainly because of the low efficiency and reliability of its resource utilization. Packet switching technology improves the ...
On the other hand, packet switching is non connection oriented, and has inherent defects for some real-time transactions. Although there are a series of mitigation measures, such as resource reservation, it is not enough to solve the fundamental problem. Therefore, these business QoS problems are...

An improvement to a spread-spectrum, code-division-multiple-access (CDMA) cellular system having multiple circuit-switched (CS) remote stations, multiple packet-switched (PS) remote stations and a base station per cell. The CS-remote station transmits a spread-spectrum CDMA signal, with a chip...

1. Datagrams Switching 1. Each datagramis a packet which is treatedindependentlyas it traverses the network,each switch in the network must decide where to send that datagram next. 2. It is possible therefore that two datagrams from the same message may take entirely different routesto reach...
采用“存储——转发”技术，从源站发送报文时，将报文划分成有固定格式的分组（Packet），把目的地址添加在分组中，然后网络中的交换机将源站的分组接收后暂时存储在存储器中，再根据提供的目的地址，不断通过网络中的其它交换机选择空闲的路径转发，最后送到目的地址。虚电路可以是临时连接，也可以是永久...
