HTTP/TCP Connection and Flow Characteristics
Joachim Charzinski
Abstract
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 average
is asymmetric.
