Describing technical communications
Communication ports
Communication Ports are physical points of communication that can be defined in technical infrastructures and Capacity Configurations.
Communication Ports assure physical transfer of information exchanged on service points and request points.
Communication ports comply with specific "Communication Protocols". See Network communication protocols.
Network channels
The network channels connect hardware resources between each other, to organizational resources or to communication ports.
Creating a network channel
To create network channel:
1. In the object inserting bar of the resource assembly diagram, click Network channel 
.
.2. Draw a link between the two communication entities.
The channel appears directly in the diagram.
To define the communication protocol associated with the channel:
1. Open the Supported Protocols property page and click Connect.
2. In the query window that appears, select the communication protocol that interests you and click Connect.
The protocol name appears alongside the channel.
Network communication protocols
A Communication Protocol is supported by network channel.
For example, an HTTPS protocol is based on an HTTP protocol for transport, those protocols are based on TCP, which is itself based on Ethernet.
A user may wish to build a customized layer of communication protocols and assign these to communication ports and communication channels.
Communication protocols supported by a communication port must be compatible with the communication ports to which they are connected.
