Capacity is defined as the maximum amount of data that can be transferred over a network path. There are three common data rates used to estimate capacity: peak data rate, which is the fastest transfer speed available in short bursts; sustained data rate, which measures the total data delivered over time and is used to improve system performance; and minimum data rate, which is the slowest transfer speed and is important for applications like video streaming that require a consistent data flow.

2. Definition - What does CAPACITY mean?
CAPACITY is the complex measurement.
 CAPACITY is the maximum amount of data that
may be transferred between network locations over
a network path.

3.  Estimating a data rate is based on transmission
characteristics (e.g., traffic flow).
 Commonly used data rates include:
 PEAK DATA RATE (PDR)
 SUSTAINED/THROUGHPUT DATA RATE (SDR)
 MINIMUM DATA RATE (MDR):

4.  PEAK DATA RATE (PDR) :
 It is the fastest data transfer rate for a
device.
 typically available in short bursts(high-
bandwidth transmission over a short period)
during transfer activity.

5.  SUSTAINED/THROUGHPUT DATA RATE (SDR) :
 Throughput is the total data delivered in a specified
amount of time.
 Measuring in terms of weight /capacity and
management "pockets"
 Identify higher data transfer rates from the disk to
the computer .
 Used to improve the system performance.

Ex: NetGear

6.  MINIMUM DATA RATE (MDR):
 It is the reverse of Peak Data Rate.
 Slowest data transfer rate for a device.
 Ex: video bitrates(Streaming) / (buffering )
 Applications/ USED:
Transaction based application (ATM)
Credit card processing(shopping).
Banking application(deposit, withdraw).
Distributed computing(task completion).
