Redis database for allocation statuses and for event notifications
|
|
has the following schema:
|
|
|
|
1) The allocation status is stored as keys "turn/user/<username>/allocation/<id>/status",
|
|
and the values may be "new lifetime=..." or "refreshed lifetime=...". There may be multiple
|
|
allocations under the same user name.
|
|
|
|
2) Additionally, the same information is reported through the "publish" mechanism.
|
|
The same keys are used and the same status is reported, with the addition of status "deleted".
|
|
The user session that is interested in those statuses, must subscribe to the events as:
|
|
|
|
psubscribe turn/realm/*/user/*/allocation/*/status
|
|
|
|
3) Allocation traffic information is reported through the "publish" mechanism.
|
|
The keys are "turn/user/<username>/allocation/<id>/traffic". The application that is interested
|
|
in the traffic information must subscribe to the events as:
|
|
|
|
psubscribe turn/realm/*/user/*/allocation/*/traffic
|
|
|
|
Total traffic information is also reported when the allocation is deleted. The keys are
|
|
"turn/user/<username>/allocation/<id>/total_traffic". Applications interested in the total amount
|
|
of traffic per allocation can subscribe to these events as:
|
|
|
|
psubscribe turn/realm/*/user/*/allocation/*/total_traffic
|
|
|
|
Or, to receive all allocation events:
|
|
|
|
psubscribe turn/realm/*/user/*/allocation/*
|
|
|
|
4) Redis database configuration parameters
|
|
|
|
TURN Server connects to the Redis and keeps the same connection during the
|
|
TURN server lifetime. That means that we have to take care about that
|
|
connection - it must NOT expire.
|
|
|
|
You have to take care about Redis connection parameters, the timeout and the
|
|
keepalive. The following settings must be in your Redis config file
|
|
(/etc/redis.conf or /usr/local/etc/redis.conf):
|
|
|
|
..........
|
|
timeout 0
|
|
..........
|
|
tcp-keepalive 60
|
|
..........
