Link Control Protocol

What Does Link Control Protocol Mean?

Link Control Protocol (LCP) is the core component of Point-to-Point Protocol (PPP) network communication. It is responsible for controlling the PPP links for PPP suite protocols’ complete operation. It is implemented at Data Link Layer in OSI model.


Techopedia Explains Link Control Protocol

LCP takes part in controlling, managing and terminating PPP links through the following LCP frame sets:

  • Link Configuration: This establishes and configures links and verifies peer identification.
  • Link Maintenance: This estimates optimal data packet sizing and verifies configuration errors.
  • Link Termination: This terminates connections if available resources exceed requirements.

Data links must be approved by LCP prior to network transmission.
