■ Interface view
Description P2P link can use simpler link layer protocol SLIP(Serial Line IP), which is mainly used to
run TCP/IP on the P2P serial port. SLIP is only used for the asynchronous link.
SLIP only defines the start and end identifiers of frame, so as to intercept IP packet on
the serial line. Compared with PPP, SLIP has no address concept, negotiation process,
differentiation of packet types (so only one network protocol can be supported at the
same time) and error correction function.
The link layer protocol of the interface shall be consistent with that of the peer
interface.
