The DSL line in the office has been slammed lately. I'm going through the process of increasing bandwidth, but I'd also like to identify the individuals in the office who are abusing the bandwidth. Can I get away with software on one of the severs? Or, should I look into a Cisco router that monitors activity by IP? If I go with a Cisco router, should I go with a DSL router or splice in an Ethernet router between the DSL router and the switch?
