In measuring the efficiency of a network, one of the many factors to consider is packet delay. Packet delay is the total time taken for a data packet to travel from its source network to its destination. It is sometimes called latency.
High packet delay or latency are caused by, but not limited to, the following:
(i) The distance between the source network and the destination network
(ii) The size of the packet being transferred
(iii) The time taken to forward data - packet switching delay.
