Traditionally, EDI has been transported over Value Added Networks (VANs). To accommodate trading partners on different VANs, interconnects were created to route traffic between the different networks.

First generation VANs built private mailbox networks, provided basic value added services and delivered numerous system integration services. The big players were the usual big IT companies such as IBM and GEIS.

With the advent of the Internet, second generation (2G) VANs emerged that routed data over the internet, and began providing a greater variety of web-based services and less traditional system integration. In order to be competitive, these 2G VANs required the same interconnects as the traditional VANs had.

ECGrid was born out of this need, allowing 2G VANs to rapidly build their differentiating value added services, while outsourcing their interconnect needs.

ECGridOS brings ECGrid to full third generation (3G) level, allowing it to operate as a fully programmable, interconnect routing infrastructure switch between 1G and 2G VANs.


Once Interconnects were created between 1G VANs, it quickly became evident that there was a need to track interchanges that went over the Interconnects. The ANSI ASC X12 standards body developed a protocol known as the X12.56 Mailbag Protocol.

Mailbagging created a structure and mechanism by which VANs can track delivery and communicate structural problems with interchanges automatically over the Interconnects.

ECGrid is 100% X12.56 compatible and implements this protocol with any Network which will comply with the standard.

ECGrid has also developed a powerful extension of this protocol which allows X12.56 information to pass through from one ECGrid Network connection to another. Please contact ECGrid NetOps if you are interested in implementing this feature.

ECGrid Connected Networks

ECGrid provides full interconnect capability to multiple Value Added Networks and Service Providers and can route data to were it needs to go.
