[SR-Users] Accessing Message Buffer in Kamailio

[Daniel-Constantin Mierla]

Hello,

for UDP and SCTP traffic there is no buffer in Kamailio. The kernel does 
buffering and kamailio receives each datagram at once, process it and 
then gets the next one.

For tcp (tls), there is a read buffer in kamailio to parse as received, 
because it has to split the traffic in sip messages. But still the main 
buffer is in kernel.

In other words, kamailio doesn't have access to pending packets from the 
network. Ratelimit module works on the number of packets processed by 
kamailio (those already read from kernel buffer).

Cheers,
Daniel
