Figure 1: Common Electronic Submissions Gateway (CESG) High Level Architecture

The Trading Partner (TP) requests a digital certificate from the Certificate Authority (CA). The CA assigns a digital certificate to the TP.

The TP transmits a regulatory transaction. It is first received by the Food & Drug Administration (FDA) portion of the gateway. The TP receives two FDA Acknowledgements once the transmission is complete.

After passing through a firewall, the regulatory transaction is then routed to the inbox of the Health Canada portion of the gateway. The regulatory transaction routed to the Storage Area Network in the Health Canada Viewing Tool.

An Acknowledgement Receipt is created and sent to the outbox. This Acknowledgement Receipt is then routed back through the Health Canada and FDA portions of the gateway and sent to the Trading Partner. A MDN is also sent to the FDA Gateway confirming that the Health Canada received the regulatory transaction.

The regulatory transaction then undergoes Validation and Import. If it fails validation, the regulatory transaction is placed in the Failed Validation folder. If it fails Import, the regulatory transaction is placed in the Failed Import folder. After a successful Import, the regulatory transaction is stored in the eSub portion of the Storage Area Network.
