Kendall's Notation

In Queueing Theory , Kendall's Notation is used to describe or classify the queuing models.

A / B / C / ( D / E / F )

A - It represents the arrival pattern of the requests to the system.

B - It represents the servicing pattern the system.

C - It represents the total number of servers in the system.

D -It represents the total number of requests that can be queued in the system.

E -It represents the calling source (i.e) the customer base

F -It represents the service discipline of how the job that gets served by the system.

Example :

1. M/M/1/20/30/FIFO = markovian arrival rate , markovian service time , 1 server queuing model , maximum queue length as 20 , user base as 30 , service discipline as First In First Out (FIFO).
