Chapter 26
Developing a Communications Express ArchitectureThis chapter contains Communications Express basic deployment architectures. Depending on the features you want to implement in your deployment, you will need to install different sets of hosts and other networking infrastructure.
This chapter contains the following sections:
Basic Communications Express ArchitectureThis basic Communications Express architecture provides Calendar, Address Book, and Mail modules in a web container on a single host. Messenger Express is the standalone web interface mail application that uses the HTTP service of the Messaging Server. Messenger Express is deployed on the same system as the Calendar and Address Book modules.
To provide this basic functionality, you need to install the following components:
In this example:
The following figure shows the basic Communications Express architecture.

The following table explains the protocols and port numbers used by this architecture.
Communications Express on Remote Host ArchitectureFigure 26-2 shows a Communications Express architecture for both intranet and Internet users. The intranet users log on to the Communications Express back-end host. The Internet users log on to the Communications Express front-end host in the DMZ, which then communicates with the back-end host. Single sign-on is enabled on the back-end host.
You install the front-end host with the following components:
You install the back-end with the following components:
Figure 26-2 shows the Communications Express on remote host architecture.
