One of the features of computer networks is to group the flow of information transmitted by adding control information, and send the packet to the destination correctly. Adding control information packet are two: one is used to verify whether the receiver correctly received the error control information; the other is the sender of the packet specified in the receiver's address information. Thus the network must have the error control and addressing functions. Also required when multiple nodes simultaneously send the packet, the network must also be some sort of conflict arbitration process to decide who to send, who after the delivery. All of these data packets with control information in a network nodes through a feature called the right to send forward data link control DLC.
