The various Quality of Service (QoS) parameters in Computer Network are as follows:

Cell Loss Rate (CLR)
It is the fraction of cells that are lost during transmission.
CLR = Cell Lost / Total cells transmitted

Cell Delay Variation (CDV)
It defines the difference between the maximum and the minimum cell transfer delay.

Cell Transfer Delay (CTD)
It is the average time required for cell to travel from source to destination.
Cell transfer delay is affected by segmentation reassembly and transmission delay.

Cell Error Ratio (CER)
This parameter defines the fraction of cells that contained errors.
CER = Error cells delivered / Total cells delivered

Cell Mis-insertion Ratio (CMR)
It is the number of cells inserted per second that are meant for some other destination.
It is the ratio of severely error cell blocks to the total transmitted cell blocks.
SECBR = Severely Error Cell Blocks / Total transmitted cell blocks


The factors affecting the QoS parameters are:
Propagation Delay
Capacity of Buffer
Traffic Load
Allocation of resources
Architecture of switch present in network
Media error statistics


The QoS is determined by four parameters:
i. Reliability
ii. Delay
iii. Jitter

iv. Bandwidth
