What is the main role of traffic engineering in planning a V
Solution
Please follow the data and description :
Traffic engineering :
In the stream of communication or the telecommunications a traffic engineering is a method of optimizing or enhancing the performance of a telecommunications network by dynamically analyzing, predicting and regulating the behavior of data transmitted over the respective network. This can also be called as the teletraffic engineering or else traffic management. These procedures can be implemented to the networks of all kinds irrespective of the origin.
Now moving on to the current scenario of the VoIP where the main source of communication is throught the internet and thus resides on the traffic as these procedures even be implemented in this department. So for the role of the traffic engineering in the stream of the VoIP we generally regulate or calculate the load and then balance the number of calls that are being placed and thus enhances the network capacity and efficiency.
A traffic load is calculated as the ratio of the calls that are arrived in a specified period of time to the average amount of time taken to service each call during that period. These measurement units are based on Average Hold Time (AHT). AHT is the total time of all calls in a specified period divided by the number of calls in that period, For Example :
(3976 total call seconds)/(23 calls) = 172.87 sec per call = AHT of 172.87 seconds
The two main measurement units used today to measure traffic load are erlangs and centum call seconds (CCS). One erlang is 3600 seconds of calls on the same circuit, or enough traffic load to keep one circuit busy for 1 hour. Traffic in erlangs is the product of the number of calls times AHT divided by 3600, For Example :
(23 calls * 172.87 AHT)/3600 = 1.104 erlangs
And 1 CCS is equal to 100 seconds of calls on the same circuit. Voice switches generally measure the amount of traffic in CCS. Traffic in CCS is the product of the number of calls times the AHT divided by 100, For Example :
(23 calls * 172.87 AHT)/100 = 39.76 CCS
Based on the above calculations if the rate of drops or the disturbances in the call or the efficiency of the call reduces then that the network is said to be diminished as the efficiency is poor. So to take these factors into the consideration based on the traffic engineering the system for the VoIP and its implementations are to be designed.
 Hope this is helpful.
