Re: [ns] please urgent help :how to print routing table ?????

My suggestion was to check if that info was available from TCL code. If it is only available from C++, you should use the DDD debugger to debug your code and find the exact variables/structures that you want to dump. In a lot of cases the code already has dump() functions for interesting variabl

Hi, Receiver sensitivity means the minimum power level at the receiver so that the packet can be decoded properly. As you see the values you put for Cisco increases as your data rate increases, which means when you use 64-QAM which supplies 54 Mbps, you have to supply received power level about 20
