There are many Advantages and disadvantages of packet switched networks over circuit switched networks
These two types of switched networks are both used in various transmissions of data from one end to another. A circuit switched network is a virtual connection that connects two ends and has a bandwidth, while a packet switched network is where packets of information is send from the source to the destination through any suitable connection available. Both two types of switched networks have advantages as well as disadvantages
One advantage of the packet switching network is that it utilizes the available networks because of its capability to distribute the available traffic through various connections available. This makes it much effective than circuit when sending huge amount of information. Furthermore, packet switching has much higher flat tolerance compared to the circuit network because bad performance is enhanced by the available network as well as capability of putting in sequence of the incoming packets by the involvement or assistance of the extra overhead. On the other hand, packet switching network has some disadvantages, which includes the need to resent some of the packets that may get lost in their transmission. This may cause delay in the transmission of data packets. This is best explained by Time-to-Live for packets concept. This concept means that after the packets expires or time is out, they are dropped to the next devices, which receives them and sends them to the end. This explains why this network might delay sending of information. Furthermore, some packets may not be transmitted to the end as some are dropped on their way hence may reach the destination in bad sequence.
Some of the disadvantages of circuit switched network are that messages are end quickly in wholesome as opposed to sending through paths. The message send arrives as a whole and therefore there is no need of reassembling the message hence ensures that communication...
