Applying the M/M/1 Results to a Single Network Link

• Poisson packet arrivals with rate .

• Fixed link capacity (T1 Carrier rate).

• We approximate the packet length distribution by an exponential with mean .

• Thus the service time is exponential with mean

  

  i.e. packets are served at a rate of .

• Using our formulas for an M/M/1 queue

  

  So,

  

  and
