|
|
Hi, Karl!
so whether the system works master-slave, i.e. all listeners are directed to master, when exceeded sent to slave? see figure
master - Icecast 2.3.3-kh9
slave - Icecast 2.3.3-kh10
slave see mount master, but redirect from master to slave - transfer listeners is not
config master

try adding a limiter on the master mount such as max-listeners or max-bandwidth. There does not seem to be a trigger point as to when to accept new listeners and when to bounce them to the slave.

Generally, server 3 would use server 1 as a master but I suppose you can use a cascading master chain like this.

Hello, Karl
I have a few mount. Whether I specify in section <limits>, <max-bandwidth>990M</max-bandwidth>
Will work relay?

max-bandwidth works in the limits or mount, and it's a limiter on outgoing bitrate. incoming feeds are not limited with this, whether relay or source client.

Karl, thanks
A few more question
1. <max-bandwidth>990M</max-bandwidth> - this record correct?
2. how icecast learn bandwidth my server? eth?
3. directive <bitrate> for @mount you need to specify? |

1. yes, M K are both acceptable modifiers
2. the outgoing bitrate is calculated based on how much is sent to each client. This applies to each mount and server wide. The stats show regular updates.
3. no, that is really just for YP information.
