This diagram shows the process flow when Network Bridge processes messages between 5G Network Functions (NFs) and 4G Network Elements (NEs).

In the figure, the 5G NF is on the left, Network Bridge is in the middle, and the 4G NE is on the right.

On the top, the flow goes from the 5G NF to an external ingress controller, to Network Bridge, to the 4G NE. Inside Network Bridge, the flow goes from the Mediation component, to the HTTP to Diameter Adapter component, and then to the Diameter Proxy.

On the bottom, the flow goes from the 4G NE to Network Bridge, to an external egress controller, and then to the 5G NF. Inside Network Bridge, the flow goes from the Diameter Proxy, to the Diameter to HTTP Adapter component, and then to the Egress component.
