Performance...

[Rene Kluwen]

I sent out 20 messages using the at2 
smsc.

From 3 of them, I never got a delivered-to-smsc ACK 
(and neither an NACK).

From most of them but a few, I got the DLR status 
message back. I presume, they got lost whilst sending messages.

Is this not a bad performance rate? Or do I see 
things wrong?

Only direct SMSC connection will give you such a 
performance.
You need TCP/X.25/ISDN link.
No GSM modem is able to work at this 
traffic.

  Hi list -
  
  I need to offer a solution with 10 msg/sec incoming message rate. Can I 
  get to that level of performance with the AT2 driver? Would anyone recommend 
  any special GSM modem for that performance measure?
  
  thanks very much,

I'm not quite sure if it is possible for a single GSM device to receive 10
msgs/sec...

I don't know about 300/sec but I once introduced a little bug in my code and
my message was sent repeatedly :). I've hit my smsc account limit of 50/sec
without
any problem. Except that the guys didn't liked it very much  :)

And some days ago, there were another bug (not mine this time) and my kannel
was
hited by 23k messages to the same number in http interface in a period of
three hours.
Fortunatly the  smsc blocked the number and only 165 messages were sent to
him, but
even then kannel behaved correctly and send/received every other message
from smsc
or from other http interfaces.

Kannel has a persistant storage (store.lock) that worked ok to me too. There
might be
a limit of 100 messages to each emi connection because TRN in emi is only
two digits
and that way, kannel (and any other software) can only be waiting for a
maximum of
100 ack's at any time.

If you try it, tell us the experience, please.

 Hi there..
 Did anyone have experience, what the performance of kannel is, as an SMS
 gateway?
 (msgs / sec for a certain system)
 (We are planning to connect it to an CMG gateway with 300 / sec...
 What is the size of it's queue? How many messages can it handle?

 Any idea for storing queue on a persistent storage for crash recovery?


 Thanks
