| Abstract | Providing quality of service to individual user is the major challenge of network design. Characteristics of traffic streams and their impacts are the main factors of network performance. Internet traffic has been found to exhibit self-similarity over multiple timescales which increases the blocking. Traffic study based on measurement in a real network is the way to find out, explain and validate the burstiness of traffic. In this thesis, measurements are performed in TOT network for a period of 15 days. Different tools are used to measure traffic in whole network. Data rate on links, session characteristics and packet level traffics are collected. Self-similarity is investigated using direct fractal process analysis and indirect long-tailed behavior inspection. Analysis results show that self-similarity appears in all network levels. Session characteristics, such as number of connections per subscriber, session interarrival time and session size, exhibit long range dependence. However, session duration is limited due to connection policy. Profiles of aggregated session rates indicate strong degree of self-similarity. Packet size distribution is not heavy-tailed but self-similarity appears in arrival process. Packet rate provides low level of fractal behavior with Hurst parameter 0.62. |
