We currently terminate our WAN links (1Gb) on 6504 switches and no QoS is configured - the particular model we have is coming to EOL and we need to replace them with either new chassis and Sups or routers.
We will need to implement QoS on these devices as our links are becoming congested and we will start to run video conferencing over them. My question is - is there any benefit installing a router over a switch with regards to QoS performance? I understand that the 6504 switch will queue and schedule the traffic in hardware and remark and police on the PFC.... I am guessing that a router, e.g 7206VXR, will have to process all the traffic in software but the ease of configuration of QoS on the router is inviting.
I just need to justify the decision either way as the business thinks that a router should be used and are requesting pros and cons for each device.
Any comments are most welcome
