please I am having serious challenge at work. Our branches are experience high latency and slow link. They is need for urgent BW upgrade,but of course first,the management needs a comprehensive network monitoring and analsysis. They want to know who(user) is doing what(protocol and application), and when(time). I notice cisco routers can really do this (please correct me). I need a good software to do this as my job is on the line.I am a CCNP and expectation is really high.
