Kindly explain the relation between GOS and Traffic by suitable examples.10th December 2002 at 09:02 #34934Pedro Saraiva dos SantosGuest
If a system is dimensioned with a GoS of 1%, that means that the maximum users rejected due to lack of resources is 1%, for a specified traffic offered or a number of traffic channels – See Erlang B table.
With 14 channels and a GoS = 1%, if you see the Erlang B table, you have an offered Traffic of 7,35 Erl. What that means ?
1) It means that if you have that offered traffic to the system, with that GoS of 1%, your system will carries (7,35-0.01*7,35)Erl.That value will be at the same time the median number of traffic channels occupied,in the busy hour traffic, 1 % of that traffic will be”refused” due to lack of resources.
2) In other words, with that traffic offered ( 7,35 Erl), you will that 1% of users, wouldn´t have access to the sistem.14th December 2002 at 11:17 #34935PraveenGuest
Can just clarify little more on GOS28th December 2002 at 11:17 #34936IoannisGuest
I would like to ask that if we have a five full availability trunk circuits which are offered 20 calls/hr and each call has a duration of 3min for example which is the GOW of the system .
I m a little bit confused about the difference between the carried and the Offered traffic.
In this example which is the offered traffic?
I would be grateful if someone helped me with my query.

You can do this as follows
offered load A (erlangs)= C * T
where C= No of calls offered
T = mean Duration of call
taking the values of ur data
A= 1 Erlang
Using Engest formula since you have finite sources
P.S:I need the comments of other experts that if this correct or Not.
offered traffic is that which is attempted on the trunks
and the carried traffic is which is answered
