چکیده
Currently, most traffic in the Internet backbone and access networks is World Wide Web (WWW) traffic. On the basis of recent long-time traffic traces we present characteristics of WWW traffic for different flow levels, namely port-to-port, host-to-host, and total client access. Using flow duration distributions, we obtain estimates for the point in time when a shortcut connection should be established. Investigations of the correlation structure of different flow characteristics reveal that symmetrical connections occur even at high bit rates. A large number of TCP connections can therefore benefit from symmetric access network bandwidths although HTTP traffic on an average is asymmetric. © 2000 Elsevier Science B.V. All rights reserved.

Procedures and tools for analysis of network traffic measurements
We present procedures and tools for the analysis of network traffic measurements. The tools consist of stand-alone modules that implement advanced statistical analysis procedures and a flexible web-based interface through which a user can create, modify, save, and execute experiments using the statistical analysis modules. The tools do not assume a specific source traffic model, but rather proc...
متن کاملA large deviations approach to the transient of the Erlang loss model
This paper deals with the transient behavior of the Erlang loss model. After scaling both arrival rate and number of trunks, an asymptotic analysis of the blocking probability is given. Apart from that, the most likely path to blocking is given. Compared to Shwartz and Weiss [14], more explicit results are obtained by using probabilistic arguments. The computation method is applied to the probl...
