compressed SLIP (IP) (CSLIP)

Compressed SLIP (CSLIP) is a variant of the Serial Line Interface Protocol (SLIP). The CSLIP protocol uses Van Jacobson compression to compress the TCP header.

Using Compressed SLIP (CSLIP), the compressed headers can 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 the User Datagram Protocol( UDP).

Compressed SLIP was specified by the Internet Engineering Task Force( IETF) and is described in RFC 1114.
