Locations and Bandwidth calculation.

I'm trying to clarify how CallManager calculates bandwidth used when a call is placed between devices in two seperate logical locations.

Is the bandwith cost of the call deducted from both locations bandwidth budget?

Re: Locations and Bandwidth calculation.

Hi

Yep - that's it.

If a call goes from Location A to location A, no bandwidth calc is done.

If a call goes from location A to a device with no lcoation set, it deducts from location A.

If it goes from loc A to loc B, then bw is deducted from the allocation for loc A and Loc B.

So if you have a hub/spoke network you could just assign devices that are in remote sites to locations to simplify the config.

If you have an MPLS WAN you would have a location for all sites...

Re: Locations and Bandwidth calculation.

Aaron,

How does the MPLS change things?

No hub?

Re: Locations and Bandwidth calculation.

Thats correct. You need not have a hub and spoke concept in MPLS. Service provider will carry the traffic (after tagging) through their cloud between the any 2 sites.

Re: Locations and Bandwidth calculation.

MPLS does not really change the anything from the Location perspective, you still assign each site to a different location and assign the bandwith that is availale for that site. To guarantee good quality to voice do not assign more bandwith to the location that is assigned to your LLQ priority class. So, if you configured your router to prioritize 512 kbps for voice, set the location bandwith on CallManager to 512 kbps.

Hi

True, MPLS doesn't change things in theory.. but often you see installs where no devices have a location set (i.e. if it starts as a single site setup) except for devices in remote offices.

I was just pointing out that if you have an MPLS network you need to make sure all devs are configured with a location... ideally you'd do this anyway but it's not always the case.
