[Live Streaming ] Caching on Edges

Hello,

i have some questions on Edge/Origin with Live Streaming :

1- Would live streaming content (not vod) be cached on Edges ? , so that quality of streaming will be better....

2- i'm using 1 Origin server + 2 edges, i've put the following config on my edge Vhost.xml servers

<CacheDir enabled="true" useAppName="true">

               <Path>/cache/mydir/</Path>

            <MaxSize>64</MaxSize>

  </CacheDir>

is that a good configuration for caching ?

3- Actually, streaming is working when i put each edge as rtmp link on my jw player, i look forward to set up an load balancer between those 2 edges. is there an step by step guide for that ?, i have found here some links

• www.adobe.com/go/learn_fms_redundancy_en
• www.adobe.com/go/learn_fms_clustering_en
• www.adobe.com/go/learn_fms_scalable_en

but , don't know what to choose and didn't find step by step guide for those load balancing methods ....

4-i've found also some docs talking about round robin method, how to set up it ?

5-if i chain my 2 edge servers like this : rtmp://edge1/?rtmp://edge2/?rtmp://origin/app/inst , would that improve the quality of streaming ?

Kind Regards,
