When an ethernet frame arrives at a computer, the ethernet layer must hand the packet that it contains to the next higher layer to be processed. the act of finding the right higher layer to pro-cess received packets is called demultiplexing. we know that in our case the higher layer is ip. but how does the ethernet protocol know this? after all, the higher-layer could have been another protocol entirely (such as arp). we have the same issue at the ip layer – ip must be able to deter-mine that the contents of ip message is a tcp packet so that it can hand it to the tcp protocol to process. the answer is that protocols use information in their header known as a "demultiplexing key" to determine the higher layer. o true o false
