Its four main functions include determining if the network is set up properly for information transfer, configuring a reliable peer connection between different systems, optimizing data packets for transmission to the remote system and terminating connections if the network's resources exceed requirements.

The LCP also monitors changes in network connections, and it automatically terminates the connection to a remote computer system if the remote system starts transmitting misleading or strange data. This is to prevent unauthorized access to the network and is a safety measure to prevent hostile actions over the network connection.
