The primary difference between serial line internet protocol(SLIP) and Point-to-point protocol(PPP) is that the former is the predecessor protocol of the latter. The point-to-point protocol, on the other hand, is the protocol that succeeds the serial line internet protocol. So let's debate the Difference between SLIP and PPP to understand more about it.
What is PPP?
The point-to-point protocol(PPP) is the predecessor protocol is the serial line internet protocol. point-to-point protocol(PPP) is the successor protocol to serial line internet protocol.

What is SLIP?
The serial line internet protocol(SLIP) is to send IP datagrams across the modem line. The SLIP data format is made up of data followed by a special END character that indicates the end of the data. To avoid a false stop if the data contains an END character, SLIP inserts an ECS character before the actual END character so that the receiver can receive the entire message/data. The maximum packet size specified in RFC 1055 is 1006 bytes.

SLIP Vs PPP | Difference between SLIP and PPP:
- SLIP expands to serial line internet protocol while PPP stands for point-to-point protocol.
- SLIP encapsulates IP packets while PPP encapsulates datagrams.
- IP protocol is the only protocol supported by SLIP. PPP provides support for the other layer three protocol also.
- PPP offers authentication, error detection, error correction, compression, and encryption whereas SLIP does not have these features.
- In SLIP the IP addresses are statically allocated. PPP performs the dynamic assignment.
- Data can be transferred in a synchronous mode in SLIP, and PPP facilitates synchronous and asynchronous modes for data transfer.
- SLIP is an outdated protocol, though it is still used in some places. It is good for just bridging the gap between the IP at layer 3 and the serial link at layer 1. PPP is the newer protocol used for the same purpose as the SLIP but offers several new features.
- SLIP is a predecessor protocol of PPP. PPP is SLIP's successor protocol.
- SLIP encloses the internet protocol(IP) packet. PPP encloses the datagram.
- SLIP does not provide authentication. PPP provides two-way authentication.
- SLIP is a deprecated protocol that is still in use in some places like IBM OS. PPP is a successor protocol that accomplishes the same goal but adds a few more capabilities.
- The derived protocol from SLIP is compressed SLIP. While the derived protocol from PPP is PPP over ethernet and PPP over ATM.
- SLIP can be used in applications where PPP is not much required to be used because of its minimal overhead. PPP should be used only in those applications where it is required otherwise it is a waste of bandwidth as header and padding will always be associated with packet sending.
- SLIP simply adds an end character to each packet. PPP adds a header and padding information at the end of a packet before sending it.
- To make a successful connection with SLIP, the settings must be coded in advance. PPP can auto-configure connection parameters during initialization. The whole process works in the following way- firstly, the client and host converse, and then they agree on the appropriate parameters to use. In this way, most settings do not need to be input manually, auto configuration makes setup much easier.
- SLIP works only with TCP/IP. There is no method to indicate protocol type because it lacks a type field. As a result, SLIP cannot be used to perform a variety of protocol functions. While PPP can be used in a variety of protocols.
