What is traffic intensity in computer networks?

What is traffic intensity in computer networks?

In telecommunication networks, traffic intensity is a measure of the average occupancy of a server or resource during a specified period of time, normally a busy hour. Telecommunication operators are vitally interested in traffic intensity, as it dictates the amount of equipment they must supply.

What holds true for traffic intensity?

Explanation: The traffic intensity offered by each user is equal to the call request rate multiplied by the holding time. Each user generates a traffic intensity A=λH Erlang. Here, H is the average duration of a call and λ is the average number of call requests per unit time for each user.

What is traffic intensity in operations research?

traffic intensity: A measure of the average occupancy of a facility during a specified period of time, normally a busy hour, measured in traffic units (erlangs) and defined as the ratio of the time during which a facility is occupied (continuously or cumulatively) to the time this facility is available for occupancy.

What is the unit of measurement of traffic intensity?

erlang
The unit for measured traffic intensity is the erlang, and (2) represents the average number of busy resources over the time interval (t1,t2). If the traffic system blocks some of the arrivals, the measured traffic intensity is a measure of carried load and not of the offered load.

How do you get traffic intensity?

To work out the traffic intensity, take the call minutes and divide by 60 to get the number of call hours. So, 600 call minutes / 60 = 10 Call Hours. Now the technical unit for Call Hours is called an Erlang. So the traffic intensity = 10 Call Hours = 10 Erlangs.

What is traffic intensity in Queueing theory?

Traffic intensity is a measure of how busy a system is, and is defined as the ratio of mean service time to mean interarrival time, u = lambda/mu. Server utilization, the traffic intensity per server, is defined as. rho = u/c = lambda/(c mu)

What is lost call system?

The type of system by which a blocked call is simply refused and is lost is called loss. system. Most notably, traditional analog telephone systems simply block calls from entering the. system, if no line available.

What is traffic intensity formula?

The traffic intensity is the length of time that all of the phone calls would take if ordered end to end. To work out the traffic intensity, take the call minutes and divide by 60 to get the number of call hours. So, 600 call minutes / 60 = 10 Call Hours. Now the technical unit for Call Hours is called an Erlang.

What is the formula for Erlang in traffic intensity?

What is carried traffic?

Carried traffic in erlangs is the average number of concurrent calls measured over a given period (often one hour), while offered traffic is the traffic that would be carried if all call-attempts succeeded.

What is the average number of customers in the system?

Average number of customers or units waiting in line for service. (D-14) L = Lq + λ/µ The average number of customers or units in the system. (D-15) Wq = Lq / λ Average time a customer or unit spends waiting in line for service. (D-16) W = Wq + 1/µ Average time a customer or unit spends in the system.

What is the outgoing traffic intensity to the public network?

What is the outgoing traffic intensity to the public network. Solution: A = μ *H μ = 240 calls/hr and H = 5 minutes A = (240 calls /hr) x (5 min/call) = 1200 min/hr Erlang cannot have any unit so A= 1200 min/hr * (1 hour/60 minutes) = 20 Erlangs So 20 hours of circuit talk time is required for every hour of elapsed time.

What should traffic intensity be on MSC call?

A call established at 1am between a mobile and MSC. Assuming a continuous connection and data transfer rate at 30 kbit/s, determine the traffic intensity if the call is terminated at 1.50am.

Which is a dimensionless unit of traffic intensity?

7.   Erlangs: Traffic intensity (named after of a Danish mathematician) is the average number of calls simultaneously in progress over a certain time. It is a dimensionless unit.

Which is the best definition of offered traffic?

15.    Offered traffic is the traffic intensity that would occur if all traffic submitted to a group of circuits could be processed. Carried traffic is the traffic intensity actually handled by the group.
