Hi, all, I'm a newbie to ns. Recently, I developed a network application(web cache based) on my server. This application operates on http requests from a subnet. Now I want to simulate a large amount of http traffic (only consider those send by machines in the subnet) to the application to test its efficiency and stability. There are several basic requirements for my test: (1). ip spoofing: at the application side, I need the http requests look like they are coming from different ip addresses (given a range: such as 192.168.*.*) (2). the destination of the http request must be vary: since I'm using web cache in my application, I want the http requests to be either cache hits or cache misses--as the situation in a real network. (3). my server is connnecting to internet through an ethernet connection, I definitely don't want the simulation mess up the network by sending a huge amount of traffic. Can any expert tell me is it possible to achieve my goal using ns2? And where should I start? Jian Thanks.
