Abstract: The development of IP telephony shows that providing traditional telecom service on the Internet is becoming a trend. This paper focuses on the maximum queuing delay for small-scale traditional telephony streams accessing Internet under certain conditions. It is proved that the result of the simulation is the same as that of the theoretical analysis. The conclusions in this paper can be used to evaluate the queuing delay for various fixed-rate services transported on Internet.
