Re: Status of EDI-over-FTP?
There still may be hope for using FTP for Internet EDI.
Has anybody looked at the "Secure FTP" product that COMM-PRESS is selling?
I talked with the guys at the COMM-PRESS booth at the DISA conference in
Orlando and it sounds like it solves some problems with FTP. The word is a
very large retailer will roll out Internet EDI to all their trading
partners with this product. And it will traverse the firewalls of the
VAN's selling Internet access via their IP EDI trading partner networks
(e.g. IBM Global Network/ Advantis).
My worry is that HTTP/Post just is not robust enough for the high end EDI
programs (My largest client sends out 2 to 20 megabyte EDI invoice
transmissions on a regular basis -- yes, one was 20 megabytes!).
In the retail industry the transactions are getting huge, especially the
ones like the 852 Product Activity Data. Internet EDI is really the only
cost effective solution for this level of EDI.
By the way, standard FTP through the IBM GN's SOCKS firewall to the
Internet does work fine (I have used it - but only for non-EDI production
file transmissions). But, there is that problem with standard FTP's
unencrypted user id's and passwords.
