Separate Physical LAN for Voice Traffic

CSCO11751061 · ‎02-17-2014

HI everyone,

How common is it to set up an entirely separate switching and routing infrastructure to handle voice over IP traffic? I'm curious if this would be necessary as opposed to just logically separating the traffic via a voice VLAN. Any input would be much appreciated.

I have see this as some Trading firms as they do not want QoS due to additional overhead and latency, their trading apps need priority over voice and everything else hence separate networks, most other industries live with logical partitioning.

HTH,

Chris

Thanks for this info. Can anyone else weigh in on how common this is?

Not very common at all, as I said I have only seen this at Trading companies (very typical to that market), but that is a small percentage of all deployments. I have worked with pretty much every imaginable market and have not see it anywhere else.

HTH, please rate all useful posts!
