- Alternatively, messages to a major customer may share a port with
all messages to a VAN that serves most other customers and the trading partners.
- The VAN does not process the message files until all messages
in queue are transmitted to the company's VAN mailbox (because VANs, by
definition, are store-and-forward networks.) This may take 15 to 30
minutes, depending on the number of messages.
- The VAN takes another 10-15 minutes for sorting and transmitting
the files to the mailboxes of the trading partners.
