Grade of Service (GoS)

Image
Grade of Service (GoS) Video GoS is a measure of the probability that a percentage of the offered traffic will  be blocked or delayed. Grade of service is used to observe and measure how many calls are  offered, carried and lost in the system.     GoS is also defined as proportion of calls which are allowed to fail in busy hour due limitation or economic reasons of the amount of switching equipment.  The term GOS, B is defined as the ratio of lost traffic to offered traffic: B= Number of Call Lost /  Number of Call Offered or B=  Traffic  Lost / Traffic  Offered For more information:  https://en.wikipedia.org/wiki/Grade_of_service

Introduction Of Teletraffic Engineering

Introduction Of Teletraffic Engineering Telecommunications traffic engineering ,  teletraffic engineering , or  traffic engineering  is the application of traffic engineering theory to  telecommunications . Teletraffic engineers use their knowledge of  statistics  including  queuing theory , the nature of traffic, their practical models, their measurements and  simulations  to make predictions and to plan telecommunication networks such as a  telephone network  or the  Internet . Traffic is defined as a total number of call passing through over a trunk.Channel is defined as a transmission medium.The field was created by the work of  A. K. Erlang  for  circuit-switched  networks .A good example of the use of teletraffic theory in practice is in the design and management of a  call center . Call centers use teletraffic theory to increase the efficiency of their services and overall profitabi...

DIFFERENCE BETWEEN ERLANG AND GRADE OF SERVICE Erlang Erlang is the unit of telephone call traffic. It is defined as average number of calls in progress at some time. Erlang equation is mentioned below. Erlang traffic measurements are carried out by wireless network designers to understand the voice traffic patterns in the network. This will help them derive how many lines will be needed between telephone system and PSTN central office(CO) or between the two cellular/wireless networks. Erlang A = C*h/T Where, C is average no. of call arrived during time interval T h is the average call holding time. In North America CCS(Call Seconds per hour) is used in place of Erlang. 1 Erlang = 36 CCS. Erlang Traffic models Following section mentions difference between Erlang B, Extended Erlang B and Erlang C. • Erlang B: It is used to derive number of lines needed when traffic in erlangs during busy hour is known. This traffic model is mostly used. It assumes that blocked calls are c...
