QoS Bandwidth

[haitham.jneid]

Hi Experts,

I have a total bandwidth of 200Mbps and I need to distribute this bandwidth on 200 apartments in a way that each apartment could have up to 25Mbps. How can I achieve that without facing any bandwidth starvation.

thanks,

Hi

You could use police or shape, the following link could be useful:

Hi Haitham,

Agree with Julio , Best way is to opt either policing or shaping based on your need..

The main difference between the two is ..

Traffic policing propagates bursts. When the traffic rate reaches the configured maximum rate, excess traffic is dropped (or remarked).  

Traffic shaping retains excess packets in a queue and then schedules the excess for later transmission over increments of time. The result of traffic shaping is a smoothed packet output rate.

Example for traffic policing & Shaping ..

checkout the link for more clarification.

Hope it Helps..

What can be done depends on the device's QoS features and also what your overall topology is.

You may be unable to preclude all cases of bandwidth starvation.

What's posted, below, would be an example of what you might be able to accomplish on a Cisco ISR.
