| Abstract | International revenue contributes up to 40% of the total revenue of VNPT. Since 2002, VNPT has not been the monopolized international telecommunication operator in Vietnam. The competitors provide VoIP international traffic service. Consequently, the measurement and the analysis of international traffic are extremely important to manage network. In this research, traffic measurement was performed for 28 days in HCMC Gateway, the place to supply the international telecom service for Ho Chi Minh City and 19 cities/ provinces in Southern Vietnam. This is the center area of economy and make up three-fourths of the whole international telecommunication traffic in Vietnam. The most important traffic parameters such as traffic flow, busy hour traffic flow, time difference, mean holding time of call, and day to day traffic variation are measured. Ho Chi Minh City has the high ratios between international incoming traffic and outgoing traffic , most international traffic is incoming traffic. On working days, this ratio is as high as 1.5 but during weekend and special holidays much higher. The charging rate of VoIP calls is about 10% cheaper than traditional calls. Consequently, international VoIP service calls are not popular, representing only 16.6% of the total calls, because of the low quality and the unfavorable charge. The results have shown that international call duration cannot accurately be modeled by exponential distribution. Mean holding time of bothway international calls a day typically vary between 4.1 minutes to 5.6 minutes. The mean holding time of incoming calls is about 2.4 times longer than mean duration of international outgoing calls. |
