 Delay – Delay is a measure of time delay experienced in a system. The precise definition of which depends on the system and the time being measured. The delay of a network specifies how long it takes for a bit of data to travel across the network from one node to another.
Packet loss – Packet lossmeans when one or more packets traveling across a computer network to particular destination it is fail to reach their. Every data packet has a life time to when it is traveling on a network. If it is expired due to traffic congestion the packet will be loss.
Jitter – Jitter is the variation in the delay of received packets. If we sent data packets evenly spaced intervals, but due to traffic congestion, improper queuing or configuration errors packets may come at unequal intervals.
Echo –Echo means when a person is specking with a phone he will hear the same voice through earpiece with the delay.
