I dont have any experience with ColdFusions SMPP implementation but I have
experience with oserl, (the erlang SMPP implementation).
In SMPP You can send several requests to the SMSC without waiting for a responce
for the previous requests.
The operators normally do not like it when an ESME sends a flod of requests so
they impose some limits on what You are allowed to do, the most common are
1, windowing, i.e. You may only have N outstanding requests that have not
received a response
2, rate limit, i.e. You may only send N requests per second
(In SMPP 5.0, there is a new congestion control mechanism, but I do
not think that
there are that many operators that support SMPP 5.0 yet.)
I few minutes googling on coldfusion and smpp I found this
Just let me know if You have any more questions on SMPP or oserl.
