In [[computing]], the '''Link Control Protocol''' (LCP) forms part of the [[Point-to-Point Protocol]]. In setting up PPP communications, both the sending and receiving devices send out LCP [[packet (information technology)|packet]]s to determine specificthe informationstandards thatof the prospectiveensuing data transmission. LCP is logically a [[dataTransport Layer]] transmissionprotocol willaccording require.to the The[[OSI LCPmodel]], however occurs as part of the [[CommunicationsData protocol|protocollink layer]] in terms of the actual implemented [[Network stack]]:

The LCP [[Communications protocol|protocol]]:

* checks the identity of the linked device and either accepts or rejects the [[peer-to-peer| peer]] device

* determines the acceptable packet size for transmission

Line 8 ⟶ 10:

* Code: Operation requested: configure link, terminate link, ... and acknowledge and deny codes.

* data: Parameters for the operation

LCP was created to overcome the noisy and unreliable physical lines of the time (e.g. phone lines on dial up modems), in a way which didn't lock the PPP protocol into specific proprietary vendor protocols and physical transmission media.
