Hreap restrictions and limits

Massimo Baschieri · ‎01-16-2009

Is there any structural limit in the deployment of an hreap solution?

I mean if there is some limitation in the number of hreap ap's/sites on 440x controllers, a minimum requirement for wan bandwidth/delay and so on.

I think it's particularly interesting to know how much control bandwitdth needs to be reserved on the wan link for each remote ap.

Tnx,

Max.

Hi Max,

There are some excellent design tips in this good doc :)

H-Reap Design and Deployment Guide

Hope this helps!

Many thanks, very nice doc, I should have found it by myself :-(

However it doesn't advice about bandwidth requirements of the lwapp control protocol, maybe it's so tiny that doesn't deserve a mention, anyone knows?

Tnx,

Max.

Hi Max,

You are most welcome my friend! Here is some related info;

For HREAP's connected to a centralized wireless LAN controller, the WAN link must support a minimum speed of 128-kbps WAN throughput and 100-ms maximum roundtrip latency between each HREAP and the wireless LAN controller.

Hope this helps!

Hi Rob,

as usual you are aware of docs I even cannot find by myself, I feel like a broken shoe :-)

128k for each hreap is a lot of bandwitdh, in fact it limits the number of hreaps to a very few each remote site.

Anyway, tnx a lot.

Bye,

Max.

Hey Max,

Don't feel alone here my friend :) Finding docs here sometimes is like finding the proverbial "needle in a Haystack"!

Cheers!
