When organizing broadcast with many users, we recommend to disable embedded tracker and replace it with external tracker with a good productivity (for example, [http://xbtt.sourceforge.net/tracker/ XBT Tracker]).
===Authorized nodes===
Client have to establish connection with at least two other nodes or an authorized node, to be connected to broadcast and start playback. Authorized node is a node, which was marked by broadcast's creator as a "trustworthy". Usually it's a broadcast source and/or support nodes.
The latest versions of ACE Stream software support using list of authorized nodes in acelive-file. For this <tt>--add-authorized-peers</tt> option is set when creating broadcast, after this the list of authorized nodes is created and added to acelive-file. Broadcast source (if it's not private) and all specified support nodes are in the list of authorized nodes. Clients that received this acelive-file use the list to determine whether a node is authorized.
If the list of authorized nodes was not added to acelive-file or an old version of ACE Stream, which doesn't understand this list, is installed, then authorized node is a node, IP address of which matches address of the first tracker from trackers' list. If embedded tracker is enabled on the source, it will be the first one on the list and clients will consider the source as authorized node. If embedded tracker is disabled, to support other clients we recommend to put on the first place tracker, located on the same server as broadcast source (so addresses of the first tracker and the source matched) or use at least one support node (so clients, when starting broadcast, could connect to two peers simultaneously, even if nobody watches broadcast).
