Suppose that N Ethernet stations are trying to send at the same time, require N/2 slot times to sort out who transmits next. Assuming the average packet size is 10 slot times, then what will the available bandwidth as a function of N.
1
\(\frac{{20}}{{N\; + \;20}}\)
2
\(\frac{{10}}{{N\; + \;10}}\)
3
\(\frac{5}{{N\; + \;5}}\)
4
\(\frac{{10}}{{N\; + \;5}}\)
