Optimizing screen sharing traffic route

Level 2
Level 2

Dear Adobe,

I'm trying to make screen sharing work a bit faster and optimize traffic route. When I establish screen sharing session between two browser windows on my local computer, Wireshark tells me that the traffic is going to (, which is somewhere in California. While most of my users will be in Europe, this traffic route may cause too high delay, and I'd like to make the path shorter.

First question is - why LCCS did not establish P2P RTMFP connection? Here is debug log that appears when application connects to the room, which shows that RTMFP is available for me:

23:38:02 GMT+0400    [attempt 1 of 2] Connecting to 0/1: rtmfp:// #startProtosConnect#

23:38:02 GMT+0400    tempNetStatusHandler 0/2,NetConnection.Connect.Success

23:38:02 GMT+0400    isTunneling? false

23:38:02 GMT+0400    is using RTMPS? false


23:38:03 GMT+0400      .user descriptor from server [object]

23:38:03 GMT+0400        \\

23:38:03 GMT+0400        .userID [string]= GUEST-FACC0C17-A83B-46C4-9554-97F12DF62BE8

23:38:03 GMT+0400        .role [number]= 50

23:38:03 GMT+0400        .affiliation [number]= 5

23:38:03 GMT+0400        .displayName [string]= user

Are there some tricks to force P2P RTMFP? Is is my first question, and the second is: can I use the LCCS infrastructure (client-side libraries and ConnectNow plugin) with Adobe FMS server that is installed on my premises instead of, which is too far away from my users?

Hi there,

The traffic should be going via a datacenter on the East Coast of North

America, not California. Interestingly, the network topology is such that

the US east coast is actually very low-latency to Europe (in some cases,

faster than to the West Coast!) - we have several companies using LCCS from

Europe without latency issues.

As to the P2P question, we're not currently offering Screensharing via P2P

because in all but 1:1 scenarios, screensharing is too heavy for P2P.

Secondly, the addin we've got would need some revising to be able to do so.

For now, screensharing is hub and spoke exclusively.

hope that helps,

Nigel, thank you very much for your quick respose!

Is it possible to use ConnectNow add-in with FMS that is installed on my premises instead of hosted LCCS?
