It is a basic quantitative property of networks. Delay is a calculate how long it takes for a bit of data to cross across the network from one end to the other. It is calculated in seconds or fractions of seconds.
TYPES OF DELAY:
There are following kinds of delay:
PROPAGATION DELAY:
It described as the time to travel across medium.
SWITCHING DELAY:
It is the time needed for network element to forward data.
ACCESS DELAY:
It is the time needed to get control of phase.
QUEUING DELAY:
It is the time required in packet switches.
