You can customize the traffic going between clustered servers with a few options.
This setting will control the number of bytes sent over non-user connections. Namely, Server to Server or S2S connections.
--cm-ht-traffic-throttling=xmpp:25k:0:disc,bin:200m:0:disc
The format is as follows: {traffic-type}:{maximum-traffic}:{max-lifespan-traffic}:{action} - traffic-type Specifies the type of traffic controlled. This can either be XMPP or bin. XMPP limits the number of packets transferred, whereas bin limits the number of bytes transferred. - maximum-traffic Specifies how many bytes or packets may be sent within one minute. - max-lifespan-traffic Specifies how many bytes or packets may be sent within the lifetime of the connection. 0 means unlimited. - action Specifies the action to be taken which can be disc which disconnects the connection, or drop which will drop any data exceeding the thresholds.
This allows the specific use of a load balancing mechanism by selecting SeeOtherHostIfc implementation. For more details, see Tigase Load Balancing documentation.
