5.3.1 Introduction
CDPS defines various network domains. These include the External Domain, the National Domain
and the Common Domain. The CDPS vision includes the intercommunication with the Common
Domain, other relevant applications from the National Domain and the relevant applications from
the External Domain.
The Common Domain consists of a closed secured network called the Common Communications
Network (CCN). It enables the different applications to communicate with one another in a secured
environment. Access to the CCN is achieved through the CCN Gateways using primarily the
Common Systems Interface (CSI) protocol.
MCA use its own national network for links between its customs offices. MCA is responsible for
the national domain network, including its security.
The external domain consists of the economic operators and the government agencies. Larger EOs
have EDI connections, where smaller EOs have other means of communication (often referred to as
Direct Trader Input - DTI). This could be for example an Internet connection.
Following figure illustrates the various domains related to or in use in the CDPS.
