Drawbacks or disadvantages of Packet switching

Following are the disadvantages of Packet switching type:

➨Packet switching network can not be used in applications requiring very little delay and higher quality of service e.g. reliable voice calls.
➨Protocols used in the packet switching are complex and require high initial implementation costs.
➨If the network becomes overloaded, packets are delayed or discarded or dropped. This leads to retransmission of lost packets by the sender. This often leads to loss of critical information if errors are not recovered.
➨It is not secured if security protocols (e.g. IPsec) are not used during packet transmission.
