SMPP Asynchronous Mode

One of the biggest limitations to SMPP performance is protocol implementations that do not support SMPP asynchronous mode, or to state it more correctly, do not take advantage of the speed boost that is possible with SMPP asynchrnous mode.

SMPP Receipt Message ID Tracking Over Multiple Connections

One of the standard capabilities of NowSMS is the automatic mapping of receipt message IDs when routing messages to an upstream SMSC connection. The reasoning/logic is simple.

NowSMS saves the message ID assigned by...

NowSMS and SSL Certificates – 2048 Bit Key

In the last 6 months, many SSL Certificate Authorities (CAs) have made a switch to requiring web servers to use 2048-bit private keys. It is believed that increased computing power will make the commonly used 1024-bit keys possible to break by 2011. There is a side effect in switching to the larger keys that some old web browsers don’t support > 1024 bit keys. I can’t find a good...
