[ns] How can i measure the bandwidth in use?

2006-10-24 Thread wang laye
Hi, I am simulating a QoS Routing Protocol,in this protocol,the available bandwidth of node is caculate according: Available Bandwidth=Total Bandwidth - Reseved Bandwidth - Bandwith In Use My question is:In C++, to a mobile node,How can i measure (or caculate) the bandwidth in use?
