GPD transmits the data packet to the sink device via proxy, if the proxy device is
present in the network. In such cases, the proxy device sends the GP notification on
behalf of the GPD device. The following figure illustrates the data transmission from
the GPD via proxy.Figure 8-4. Data Transmission from GPD via
