What do you know about SLIP? |
|
Answer» Serial Line Internet Protocol (SLIP) is a basic protocol for communication over serial ports and routers that works with TCP/IP. They allow machines that were previously configured for direct communication to communicate with one another. A client might be linked to the Internet service provider (ISP) over a slower SLIP line, for example. When a client requires a service, he or she submits a request to the ISP. The ISP responds to the request and SENDS it across high-speed multiplexed lines to the Internet. The results are then sent back to the client through SLIP lines by the ISP. The format of a SLIP frame is FAIRLY simple, consisting of a payload and a flag that SERVES as an end delimiter. The flag is usually a special character with a decimal value of 192. If this flag is included in the data, it is preceded by an escape SEQUENCE, which prevents the receiver from mistaking it for the end of the frame. |
