You can use the "free" function in the router called NBAR. (Network Based Application Recognition) - this is a very powerful function that works with QoS to provide queueing and bandwidth throttling.

Some people feel the need to go find point products to do what your network equipment can already do if you just research the capabilities of the products. The additional problem is that for the products to be truly effective they must control ingress/egress at every location which means a lot more complexity and hardware in your enterprise.

In regards to previous statements about inline v. WCCP. WCCP is a good protocol and any vendor can use it, however you will find that Riverbed is very reluctant to use WCCP (not sure why) and will almost INSIST that they deploy inline. Cisco's inline deployment performs completely differently and can identify VLAN's so traffic on a VOICE VLAN for instance will be hooked to the "WAN" port and not processed. WCCP is still the best way to implement any optimization as it scales easier, load balances, and is out of path so it is easy to bring up and down during production.

I believe Nanometrics reached out to Network World for the article. I don't think Cisco knew about it when it came out.
