# RPC binding

RPC binding means binding with a remote service for an application. Because the RPC proxy
            creates a local TelAF proxy service for each RPC service, the TelAF application can
            leverage the binding section in the .adef file to set the RPC binding. The server
            interface of an RPC service shall follow the following format (replace
                `<SYSTEM_ID>`, `<SERVICE_USER>` and
                `<SERVICE_NAME>` with the correct
            information):

    <telaf>.rpcServer_<SYSTEM_ID>_<SERVICE_USER>_<SERVICE_NAME>Copy to clipboard

For instance, if the TelAF platform service `<telaf>.taf_dcs` on a
            remote system (ID=0x102) is declared as an RPC service, then the corresponding RPC
            server interface created by the local RPC server proxy is
                `<telaf>.rpcServer_102_telaf_taf_dcs`. The default client
            interface of `taf_dcs` service can access the remote DCS service through
            this server interface. The following binding allows the client interface
                `dcExe.dcComp.taf_dcs` of the DCS application to access the DCS
            service on remote system (ID=0x102) using the same TelAF taf\_dcs APIs:

**.adef file of DCS            application**

    executables:
    {
        dcExe= (dcComp)
    }
     
    processes:
    {
        run:
        {
            (dcExe)
        }
    }
     
    bindings:
    {
        dcExe.dcComp.taf_dcs -> <telaf>.rpcServer_102_telaf_taf_dcs   // Binding to remote DCS service on system 0x102 via RPC proxy
    }Copy to clipboard

Then the DCS application can call `taf_dcs_XXX()` APIs to communicate with
            the remote DCS service on system 0x102.
