PPP Link Control Protocol (LCP)

(Page 1 of 3)

Of all the different PPP suite protocols, the single most important

protocol is the PPPLink Control Protocol(LCP). LCP is the “boss” of

PPP; it is responsible for its overall successful operation, and for

“supervising” (in a way) the actions of other protocols.

PPP is about links, and LCP is about controlling those links. As I

discussed in the PPP fundamentals section, the operation of a PPP

link can be thought of as proceeding through various “life stages” just

as a biological organism does. There are three main stages of “link

life” and LCP plays a key role in each one:

o Link Configuration:The process of setting up and negotiating

the parameters of a link.

o Link Maintenance:The process of managing an opened link.

o Link Termination:The process of closing an existing link

when it is no longer needed (or when the underlying physical

layer connection closes).

Each of these functions corresponds to one of the“life phases”of a

PPP link. Link configuration is performed during the initialLink

Establishmentphase of a link; link maintenance occurs while the link

is open, and of course, link termination happens in theLink

Terminationphase.Figure 26represents a summary of the LCP link,

showing the different message exchanges performed by LCP during

these different life phases of a PPP connection.

正好需要研究下PPP的协议，这份资料比较简单，对我用处不大。但是对初学者还是有用的。
