ppp frame the field has a value of 11111111

Its job is to tell what kind of packet is in the payload field. The fourth PPP(Point To Point Protocol In Hindi) field is the protocol field. LCP provides the necessary mechanism for the two parties to negotiate an option to just omit them together and save 2 bytes per frame. Since the address and control fields are always constant in the default configuration. The exact details are defined in RFC in 1663. In noisy environments, such as wireless networks, reliable transmission using numbered mode can be used. In other words, PPP does not provide reliable transmission using sequence numbers and acknowledgments as the default. This value indicates an unnumbered frame. The address field is followed by a control field, the default value of which is 00000011. Using this value avoids the issue of having to assign a data-link address. Next comes the address field, which is always set to the binary value 11111111 to indicate that all the stations are to accept the frame.

Point To Point Protocol In Hindi:PPP(point to point)-frame-formatĪll PPP (Point To Point Protocol In Hindi) frames begin with the standard HDLC flag byte(01111110), which is a character stuffed if it occurs within the payload field. The PPP frame format is shown in fif1 below Not only can PPP (Point To Point Protocol In Hindi) frames be sent over dial-up telephone lines, but they can also be sent over SONET or true bit-oriented HDLC lines. it is not possible to send a frame consisting of 30.25 bytes, as it is with HDLC. So all frames are an integral number of bytes. In particular, PPP (Point To Point Protocol In Hindi), like SLIP uses character stuffing on dial-up modem lines. The major difference between PPP and HDLC is that the former is character oriented rather than bit oriented. The ppp frame format was chosen to closely resemble the HDLC frame format, since there was no reason to reinvent the wheel.
