Compressed SLIP (CSLIP) is a variant of the Serial LineInterfaceProtocol (SLIP). The CSLIP protocol uses Van Jacobson compression to compress the TCP header
. Compressed SLIP (CSLIP) allows the compressed headers to be transmitted over the SLIP link, reducing overhead and increasing packet throughput on the SLIP link. With CSLIP, the TCP header can be reduced from 40 bytes
to 7 bytes without affecting theUser Datagram Protocol
(UDP). Compressed SLIP was specified by the Internet Engineering Task Force (IETF) and is described in RFC 1114.
