Measured By The Tcp-based Network Measurement Research And To Achieve

As one of the greatest achievements of man's reconstruction of the world,Internet would impair the excellence of any invention of human history for its dramatic developing speed and the convenience brought to people. However, as every coin has two sides, all these are achieved through its ever enlarging scale and growing complexity. Internet traffic engineering is introduced as one of the efforts to fight against this complexity. Internet traffic engineering is defined as one aspect of network engineering, whose goal is to enhance the performance and service level of operational IP network through the measurement, characterization, modeling, and control of Internet traffic.Network measurement is a vital part of network traffic engineering. The objective of measurement is to observe and evaluate network behavior, in order to trace the key elements that influence the characteristics of Internet.In the Intenet folw, TCP Accounts for the largest share,at the same time, TCP is the most important protocle althouth other technologies have been used widely. That this is why this disquisition aim to measure TCP. To the measurement method, active Measurement and passive Measurement can be combined to measure whether the network is running well via the measuring of end to end. From the above measuring results the network can be monitoring and debugging. In the research of Internet, many excellent measuring tools have been developed and used.
