ESME congestion control #31

Closed vetss closed 6 years ago

vetss commented 6 years ago

We need to introduce a congestion control per ESME when a sending queue increased some threshold.

ESME creation / update extra commands : overload-threshold xxx - a threshold after which ESME is treated as congested (messages will not be sent to it) normal-threshold yyy - a threshold after which ESME is treated as uncongested (messages will not be sent again to it) must be: xxx > yyy

What is missed for now:

GUI allows only change values, current values are not displayed.
Let's make GUI show also a congested state of each ESME
CLI ESME show does not display a congested state too (only threasholds), let's add it into CLI too
no update in manul with a new functionality description
no update for a CLI helpers

What I can suggest in addition of what is already implemented:

1) we need also a sever level congestion option. If ESME thesholds are not configured then a server will reuse of server level settings for such ESMEs. This can help customers for default settings when SMPP network similar.

2) 2 levels of congestion (two threasholds then).

Level "no congestion"==0
level "low congestion"==1, we do not restrict traffic for it, it works as a warning
level "hight congestion"==2, we stop of sending of traffic to a ESME
