Transport level: Communication layer

The communication layer is part of the transport level and is responsible for transporting information. This layer links the internal integration solution with external systems. It represents a type of gateway to the infrastructure at an architectural level, and consists of transport protocols and transport formats.

Responsibility

The responsibility of the communication layer is to transport information using standardized protocols and formats.
