Compare circuit-switched networks versus packet-switched networks briefly.

Solution

Circuit Switch Network Packet Switch Network 1)In circuit switching network dedicated channel has to be established before the call is made between users. The channel is reserved between the users till the connection is active 1)In packet switching network unlike CS network, it is not required to establish the connection initially. The connection/channel is available to use by many users 2)Packet switched networks quality of service (QoS) is not guaranteed.Because packets may get lost during their journey. 2) in circuit switched (CS) networks quality is guaranteed. Because dedicated path is established between end points. 3)Circuit swicth network has fixed bandwidth. 3)Packet swicth network has fixed bandwidth. 4)No extra bits are sent after call setup. 4)Extra bits are sent inorder to find the sequence of packents. 5)This type of switching is connection oriented and may be connectionless also. 5)This type of switching is connectioness. 6)his is best used for transmission of audio signals and not suitable for data transmission. 6)It is best used for sending data over the network and audio and video signals can also be sent over the network in the form of packets 7)Example of circuit switched network is PSTN(Public switched telephone network). 7)packet switched network is GPRS/EDGE,VOIP
