Hi I'm trying to simulate a core network and carry out measurements based on VoIP QoS parameters... I wanna connect 3-4 WAN models to a core network which consists of routers... Can someone pls give me an idea of how to go about this using NS-2... what would my tcl scripts look like? how many nodes do i need for each WAN and how can I interconnect them to depict a proper WAN model? how can I use tcl scripts to configure a core network which consists of routers and manage traffic? Please someeone help. Thanks
