- trafficStatistics is a field that contains the statistics information regarding<br />
one interface of the IngressRouter router.<br />
- g<strong>et</strong>No<strong>de</strong>Info(int if ) is a m<strong>et</strong>hod that allows to collect the traffic statistics<br />
at interface if of the ingress router.<br />
- s<strong>et</strong>Active(boolean), s<strong>et</strong>RealRate(double) and s<strong>et</strong>OfferedRate(double):<br />
these three m<strong>et</strong>hods update the CST table with the information on the state,<br />
the transmission rate and the offered rate of each connection, respectively.<br />
- g<strong>et</strong>InLoad() and g<strong>et</strong>OutLoad(): these two m<strong>et</strong>hods r<strong>et</strong>urn, respectively,<br />
the incoming and outgoing traffic statistics for a particular interface<br />
of the ingress router.<br />
