Serial Line Internet Protocol (SLIP)

SLIP is an internet connection protocol that does not execute an error control or an address which makes it obsolete when compared to other protocols. It is the encasing of internet protocols which operate over the modem connections and serial ports. Before it is established, it will require you to set the configuration of an IP address.

It has a small overhead which makes it suitable for enclosing internet protocol packets. It has existed since the 80s for limited modem communications to 2400 bps. Its primary purpose was to allow easier transmissions across serial lines. It supports asynchronous links and can be effective on RS-232 serial ports.

The dial-up linkage to the server is based upon a slower serial line. It is not associated with the multiplex or parallel lines in which you may need to establish the connection. Workstations are capable of transmitting internet protocol packets over the line at the termination for the purposes of framing. Character staffing is used for solving the problem in situations where the flag byte (OXCO) transpires within the IP packet. In situations where the issue arises, then the two byte sequence is transmitted to provide a replacement. They include OXDB and OXDC.


Problems associated with the SLIP

The Serial Line Internet Protocol is easy and simple to use but has its own downsides.

  • It only offers support to the Internet protocol and hence it is not appropriate for use by networks which do not utilize the IP. Some of the examples include the Novell Local Area Networks
  • SLIP does not determine and correct errors which make it inefficient in executing necessary processes.
  • The Serial Line Internet Protocol does not provide any support of assigning a fluctuating IP address. The process of assignment is important since the sites of communication need allocation of a particular internet protocol address in prior. They also have to determine the addresses of each other to ensure an effective transmission.
  • It does not have the consent of being an internet standard as it makes networking impossible. The reason is that it has a variety of incompatible versions which are still in existence yet they are not efficient in carrying out the intended functions.
  • The communication sites are not aware of whom to communicate with because of its failure in providing an authentication.

The Serial Line Internet Protocol seems to be obsolete and faces stiff competition from other protocols which prove to be faster in their operations and deliver the best performance.
