- A 1500 byte message is sent over the network using a protocol stack with HTTP, TCP, IP and Ethemet. Each protocol header is 20 bytes long. The percentage of the network bandwidth "on the wire" is wasted due to the overhead is (in %).A technique for identifying and correcting errors in received data at different layers of a protocol stack is described below.A system has 7 layers protocol hierarchy. Applications generate message of length "500" Bytes. At each of the layers, a "20" byte header is added. The percentage of the network bandwidth wasted on headers is
