The main difference between High-level Data Link Control (HDLC) and Point-to-Point Protocol (PPP) is that High-level Data Link Control is the bit-oriented protocol, on the other hand, Point-to-Point Protocol is the byte-oriented protocol.
Another difference between HDLC and PPP is that HDLC is implemented by Point-to-point configuration and also multi-point configurations on the other hand While PPP is implemented by Point-to-Point configuration only.
Let’s see that difference between HDLC and PPP:
|1.||HDLC stands for High-level Data Link Control.||PPP stands for Point-to-Point Protocol.|
|2.||HDLC is a bit oriented protocol.||PPP is a byte oriented protocol.|
|3.||HDLC is implemented by Point-to-point configuration and also multi-point configurations.||PPP is implemented by Point-to-Point configuration only.|
|4.||Dynamic addressing is not offered by HDLC.||While in this Dynamic addressing is offered.|
|5.||HDLC is used in synchronous media.||PPP is used in synchronous media as well as asynchronous media.|
|6.||HDLC is not compatible with non-Cisco devices.||PPP is compatible with non-Cisco devices.|
|7.||HDLC does not provide link authentication.||While PPP provide link authentication using various protocols.|
|8.||HDLC is more costly comparatively.||While PPP is comparatively less costly.|
