Short for
Link Control Protocol, a
protocol that is part of the
PPP. In PPP communications, both the sending and receiving
devices send out LCP
packets to determine specific information that will be required for the data transmission. The LCP checks the
identity of the linked device and either accepts or rejects the peer device, determines the acceptable packet size for transmission, searches for errors in configuration and can terminate the link if the parameters are not satisfied. Data cannot be transmitted over the network until the LCP packet determines that the link is acceptable.
