Differences Between SLIP and PPP

Although SLIP evolved as the first protocol for transmitting data over serial lines, it has a few limitations. PPP is an enhancement of SLIP and offers a few advantages. The differences between SLIP and PPP are discussed in Table 2.1.

Table 2.1. SLIP Versus PPP
Can be used only with TCP/IP. Can be used with multiple protocols.
Supports only synchronous transmission of data. Supports synchronous as well as asynchronous data transmission.


CSLIP (compressed SLIP) is an advanced version of SLIP. CSLIP supports more throughput compared to SLIP because it uses a compressed version of the IP header unlike SLIP, which does not compress the IP header.
