Hi, Best use FAKE smsc to avoid charges.
1) You can use sqlbox if you want to bulk send SMS from mysql. It is faster than fakesmsc client. Look under test/ for other software as well. 2) In a spool (or file) configured in store-type and store-location. Can be a DB table, too. 3) No. Submits are asynchronous. HTTP cannot wait for so long. Besides HTTP lives in SMSbox and dlivery is from bearerbox. However, status is written to bb logs. When reaching throttling limit SMS are queued in store-location for later delivery. 4) Like pending cores or panics? No. Wherever that is possible, recovery is programmed in. If in (2) you use spool, use a very fast HD (SSD?) and a fast non-logging fs on its own partition. If handling many concurrent SMS (>30000) use an indexed filesystem like Reiser or similar. Below that, ext2 is a good choice.

We’re using a SMPP connection to an operator. But I have a couple of questions before releasing the attack: - We’re using the HTTP interface to send the SMS. Is there a faster interface (for instance, inserting the SMS in a text file or Mysql table)? - If we call the HTTP interface faster than the rate at which Kannel sends through to the SMSC, what happens? Where are the queued messages stored? (RAM, file buffers, mysql?) - I read in a post that there is a “max_pending_submits” option. What happens when reaching that number? Does the HTTP interface responds with a “3: Queued for later delivery”? - In general, is there a way to know when a disaster is near (I mean, other than counting errors in the logs) Thanks! If you can give us more advice on how to estimate the throughput (or make it better), thank you! We’ll share our findings after the test. Alejandro Woywood. http://www.AmnesiaGames.cl Av.
