AS2 is a modern communication standard that is used for transmitting EDI messages among partners and providers.
The transmission is fast, secure and reliable.
The speed of transmission is ensured by individual counterparts being interconnected directly between one another, the data interchange, thus, occurs in real time (as opposed to, e.g. e-mail).
For ensuring security are also used digital certificates – each message leaves digitally signed and encrypted.
Reliable transmission is, then, ensured by backward notifications MDN (Message Disposition Notification) that carry information about the success of the transmission.
