| Abstract: | The advantages and disadvantages of three QoS service dispatching methods in hybrid fiber and coaxial (HFC) network are expatiated. Then, the average time delay and the throughput of voice services and data services performance model that is based on the classified service dispatching method are calculated and simulated. Finally, the paper comes to a conclusion that this method insures the real time services against delay at the cost of the data services' performances. |

| Keywords: | hybrid fiber and coaxial (HFC) quality of service (QoS) dispatching method maximum posterior probability (MAP) delay estimation throughput |
