Unrestricted Bandwidth for Specific VLAN Traffic

[Henry Martel]

All,

We have a site that's having network bandwidth utilization problems. During heavy utilization periods vital monitoring systems are slowed down and disconnect from their sensors and because of the layout of the site, the monitors are connected via wireless.

I suggested shaping/policing, but the site does not want to have bandwidth restrictions due to remote connections, their monitoring systems and various other reasons. It was suggested that I create a policy that would allow for a specific VLAN to have unrestricted access to bandwidth and restrict everything else.

Any suggestion?

If you control both sides of the link, use QoS to support other than single global interface FIFO.  If you have routers that support fair-queue, I would suggest you try that.  If you have switches, you could split traffic into different classes, each with a minimum bandwidth guarantee.

Basically, instead of restricting bandwidth, guarantee bandwidth to the apps that need it.  The advantage of this, you get to use bandwidth otherwise made unavailable by a shaper or policer.

Joseph - Thanks for the reply.

What you suggesting makes sense. Guaranted bandwidth for applications is proabably better way go on this.

Thanks
