An SMPP transport for version 3.4 of the protocol, operating in Transceiver mode.
Redis is used for all situations where temporary information must be cached where:
- it will survive system shutdowns
- it can be shared between workers
One use of Redis is for mapping between SMPP sequence_numbers and long term unique id’s on the ESME and the SMSC. The sequence_number parameter is a revolving set of integers used to pair outgoing async pdu’s with their response, i.e. submit_sm & submit_sm_resp. Both submit_sm and the corresponding submit_sm_resp will share a single sequence_number, however, for long term storage and future reference, it is necessary to link the id of the message stored on the SMSC (message_id in the submit_sm_resp) back to the id of the sent message. As the submit_sm_resp pdu’s are received, the original id is looked up in Redis via the sequence_number and associated with the message_id in the response.
Followup pdu’s from the SMSC (i.e. delivery reports) will reference the original message by the message_id held by the SMSC which was returned in the submit_sm_resp.
