SLIP (Serial Line Internet Protocol) A Link Layer packet framing protocol that defines a sequence of characters that frame IP packets on a serial line. SLIP provides no addressing, packet type identification, error control, or compression mechanisms. SLIP is defined in RFC 1055 as a nonstandard protocol for transmission of IP datagrams, in the formal sense, although it has become a de facto standard. RFC 1144 defines Compressed SLIP (CSLIP), a method for improving TCP/IP performance over low-speed (300 bps to 19.2 kbps) serial lines by compressing the TCP/IP headers. Point-to-Point Protocol (PPP) performs the 74570c19.qxd 9/12/07 12:41 AM Page 444 |
