A data communication network usually comprises a multiplicity of switching nodes and links interconnecting pairs of these nodes. One of the purposes of the network is to transport packets of data from a source node to a destination node, typically visiting one or several intermediate nodes along the path. Each link can span considerable distances, using a variety of available transmission and switching facilities, such as those provided by the telephone company. In transit, one or several bits of a packet can get corrupted, giving rise to transmission errors. Error control is one of the functions of the data link control component of a data communication network. It has two aspects: error detection and error correction.
