Info

So AMPL executes the file NetworkModel.run (see Table A.3), computes the connections’ bandwidth allocation and writes these values in the output file AllocatedBandwidth.out. When OBA detects the finishing of AMPL (the Java method p.waitFor()), it reads the values of the bandwidth allocations from the file AllocatedBandwidth.out and sets these values in the CST table and then configures the token buckets at ingress routers appropriately. – IBA, the ideal bandwidth allocation algorithm proceeds in the same manner as OBA. 100
Table A.2: Java code for updating the CST table Node IngressRouter; InterfaceInfo trafficStatistics; for(int j=0; j < CSTtable.length; j++) { IngressRouter = CSTtable[j].getIngressRouter(); trafficStatistics = IngressRouter.getNodeInfo(1); if (trafficStatistics.getInLoad() > 0) { CSTtable[j].setActive(true); CSTtable[j].setRealRate((IngressRouter.getNodeInfo(0)).getOutLoad()); CSTtable[j].setOfferedRate((IngressRouter.getNodeInfo(1)).getInLoad()); } else { CSTtable[j].setActive(false); } } - trafficStatistics is a field that contains the statistics information regarding one interface of the IngressRouter router. - getNodeInfo(int if ) is a method that allows to collect the traffic statistics at interface if of the ingress router. - setActive(boolean), setRealRate(double) and setOfferedRate(double): these three methods update the CST table with the information on the state, the transmission rate and the offered rate of each connection, respectively. - getInLoad() and getOutLoad(): these two methods return, respectively, the incoming and outgoing traffic statistics for a particular interface of the ingress router. 101
