I read some white papers on Cisco qos on the 3750X and I saw vendors like Procera and Bluecoat that have bandwidth optimization appliance. So my questions are:
- what is the difference between Cisco qos and those vendors?
- Which one is better?
- If I have Cisco qos implemented on my switches, do I need those appliances and vice versa.
I know that Cisco qos on the switches is a software implementation. I guess those vendors are software and hardware.
