The major communication protocols employed for EDI are AS/2, HTTP, FTP, SMTP. These can be used in a point-to-point document interchange directly between companies or they can be used with third-party networks called VANS - Value-Added-Networks. The advantages of using a VAN is that they provide a mailboxing service so that documents can be sent or retrieved whenever you want with archiving and traceability built in. The disadvantage is the cost. Therefore the trend in communications for EDI is to setup direct, point-to-point links between organizations using primarily the AS/2 protocol which provides encrypted and verified exchanges.
