Teletraffic engineering/What is the Engset calculation?/Solution 1
Table 1 below shows the results for Erlang B and Engset calculations.
|Number of sources||10||20||100|
|Traffic offered in Erlang||5||5||5|
|Grade of Service||0.01||0.01||0.01|
|Number of links (Engset)||9||10||11|
|Number of links (Erlang)||11||11||11|
Table 1: - TABLE COMPARING RESULTS FOR ERLANG AND ENGSET CALCULATIONS FOR NUMBER OF LINES SPECIFIED FOR SAME NUMBER OF SOURCES AND OFFERED TRAFFIC AT 0.01 GoS.
Notice that the Erlang B formula specifies the maximum number of lines needed even if there are fewer sources.
