MDN Usage in AS2 by Scott Haaland

April 12, 2014 Leave a comment

An MDN (Message Disposition Notification) is a transmission level acknowledgment used in the AS2 standard, so that the sender knows that the receiver successfully acquired the message in a B2B scenario. B2B (Business to Business) is an integration term used to describe the sending and receiving of business messages between business partners. When the business messages are being sent over the internet via HTTP or SMTP, it is critical to business operators to know that the messages were transmitted successfully to the right party. In order to give assurance to the business operators, specific B2B transmission standards have been developed. We call these standards "Message Exchange Standards".

These include AS1, AS2, AS4, ebMS and RNIF, to name a few. AS2 is a very common standard for EDI messaging. It is important for everyone using the standard to do so in the same way, or else inter-operation becomes very difficult or impossible. Here is a diagram showing a typical EDI interaction over AS2 between two fictitious partners named OracleServices and MarketInc. Read the complete article here.
