| Abstract | Nowadays, the demand of using new services and applications based on broadband techniques has been more and more essential and increasing. Consequently, new technologies such as Asynchronous Transfer Mode (ATM) or Switched Broadband Internet Protocol (IP) Services are quickly developed to satisfy this pressing require. As a result, measurement and analysis of broadband traffic become important and necessary for network operation and management purposes. This research study demonstrates the broadband traffic measurement process in a Broadband Access Server for East Ho Chi Minh Telephone Company (EHTC). For both IP over ATM and IP, the incoming and outgoing traffic are measured and analyzed in some main parameters. In addition, the IP over ATM and IP traffic is shown in graphs according to profiles: hourly, daily or weekly so that the behaviors of broadband users are investigated. Moreover, the distributions of 5-minute transferred rates, packet length are studied for both IP over ATM and IP traffic. Finally, the comparisons between these traffic types are caITied out. The statistical analysis results which are shown by daily and weekly profiles show that the broadband traffic in working hours is clearly superior in volume. Namely, the busy hour of IP over ATM traffic is from 11 :00 to 12:00 while that of IP traffic is from 12:00 to 13:00.The carried traffic of IP over ATM (with incoming rate 5 Mbit/s and outgoing rate 17 Mbit/s) is significantly different to IP traffic (with 28 Mbit/s and 88 Mbit/s for incoming and outgoing). The observed packet length distributions for both IP over ATM and IP traffic demonstrate that the mean length of packets received by subscribers (about 700 bytes) is obviously larger than the mean length of packet sent (near 300 bytes). In addition, the Cell Lost Ratio in the working hours is considerably small about 10ยท6 . The average payload is approximately 43 bytes for incoming cells and 46 bytes for ougoing cells. Lastly, the diversity of customer's behavior in various areas is expressed in term of average subscriber traffic. Measuring total 5504 subscribers in EHTC, the average traffic received and sent by subscribers is approximately 685 Mbytes/day/subscriber and 216 Mbytes/day/subscriber respectively. |
