What is the serial line internet protocol?
The serial line internet protocol, also known for its abbreviation, is a means to send the internet protocol datagrams via a serial link. It sends every byte of a packet and adds one or more unique brands of brands as needed. Slip can be used by two systems to communicate via a direct cable connection or a modem link. Instead, most personal computers use POINT-to-Point protocol, but SLIP is often used where very low direction is required. Then each byte sends a packet if it is not one of the two decimal values: 219 or 192. If it is 192, the value of the end brand, Slip will send two special bytes to its place; 219 Followed by 220. If it is 219, Slip sends another two-backed code-219 followed by 221. Once all the bytes of the Internet protocol protocol have been sent, it sends a slip of 192 end byte.
Slip, removes end marks and replaces all special pairs of bytes with its original values. Some implementacE can also remove packets with zero length. The resulting datagram, if any, is then handed over to the next network layer without further analysis. Detection and error correction is left to the next layer, which must apply for the transmission of the packet if the error is discovered.
The slip specification was released by the Internet Engineering Task Force (IETF) working group in 1988 as an application for comments (RFC) 1055. Another common problem with the internet series of serial line is that there is no identification of the packet protocol. Since the slip has been designed only to process the internet protocol datagrams, it may not be a frequent problem. Slip is quite able to handle multiple internet protocols. Medicines to identify them.
Lack of Security is another aspectTo use the internet protocol of the serial line. There is no mechanism to verify the connection or any kind of data encryption in this layer by sliding. There is also no way of discovering the address of the Internet protocol for routing in another network layer. Due to the maximum packet size, the slip specification is vague, indicating a limit used by another implementation.
The internet protocol of the serial line does not compress any data of packets, although the modem on the serial link will be if used by the modem. The compressed slip (CSLIP), defined in 1990 using RFC 1144, makes efforts in this direction. Reduces the TCP header to control the transfer of each packet to seven bytes of the original 20. However, the rest of the packet remains unchanged. In 1994, PPP - defined in RFC 1661 - was created as a new robust protocol that solved many slip problems.
