DBus usage for applications and services communication through servicemanager

[Ravi Kumar Kandati]

Hi,

I have following requirement which needs to use D-Bus, where applications(App1, App2, App3 ...) will communicate to services(Ser1, Ser2, Ser3 ...) through service manager(SM) for priority handling.

                (App1, App2, App3 ...) -----D-Bus-----> SM --------D-Bus-----> (Ser1, Ser2, Ser3 ...)

I want to handle following sequence for different applications.

                Step 1. App1 sends request to SM for Ser1 through D-Bus.
                Step 2. SM sends request to Ser1 through D-Bus.
                Step 3. After processing the request Ser1 sends response back to SM through D-Bus.
                Step 4. SM sends response to App1.

In the above steps, after SM sends the request to Ser1, it can't wait for the response, because it has to process other requests. So thought of proceeding with the following implementation flow.

                SM will be having dedicated D-Bus connection to receive requests from Applicatios(App1, App2, App3 ...)
                SM will be having different D-Bus connections to handle responses coming from different services(Ser1, Ser2, Ser3 ...)

Can you guide is the above implementation procedure is fine or any better implementation?
