HDLC vs PPP difference between HDLC and PPP. WAN stands for Wide Area Network. As there is a security concerns when data leaves the company premises and transport across the links between different networks, the data is encapsulated into frames before they cross the WAN link. what is difference between hdlc and ppp protocol Difference Between HDLC and PPP. As mentioned above, PPP is a data link layer protocol based on HDLC, and is very similar to HDLC. It is used for the direct communication between two nodes. Transmission encryption privacy, authentication and compression are provided by PPP. Authentication is provided by PAP (Password Authentication Protocol)
There are lot of difference between PPP and HDLC which arises lot of questions. The following are some genric diffrences between HDLC and PPP are: HDLC. 1. It is vendor specific. 2. It doesnt support authentication. 3. It supports synchronous network only. 4. It doesnt support multiplexing. PPP. 1. It is a standard protocol. what is difference between hdlc and ppp protocol
(1) HDLC is cisco proprietary while PPP is an open standard. (2) HDLC does not provide authentication while PPP provides authentication like PAP and CHAP. (3) HDLC does not support compression The data part carry control packet or upper layer datagrams. protocol field is 1 or 2 bytes long and identifies protocol type of the enclosed packet. Possible types can be LCP packet, NCP packet, IP packet or OSI network layer protocol packet. Difference between HDLC and PPP. Refer HDLC vs PPP which mentions difference between HDLC and PPP protocols. Dec 25, 2011 HDLC vs SDLC. HDLC (HighLevel Data Link Control) and SDLC (Synchronous Data Link Control) are two protocols that provide point to multipoint interconnection between computers. The main difference between HDLC and SDLC is actually their origin. SDLC was what is difference between hdlc and ppp protocol Answer pavan kumar. HDLC and PPP are the protocols used in Leased lines and also in ISDN. HDLCHigh Level Data Control, PPPPoint To Point Protocol. mainly HDLC is cisco proprietary protocol HDLC is a simple protocol used to connect point to point serial devices. For example, you have point to point leased line connecting two locations, in two different cities. HDLC would be the protocol with the least amount of configuration required to connect these two locations. How can the answer be improved? ppp point to point is used in frame relay tech. HDLC is a cisco made protocol used in leased line (WAN connection)i. e in local loop. Differences between HDLC and PPP are (1) HDLC is cisco proprietary while PPP is an open standard. (2) HDLC does not provide authentication while PPP provides authentication like PAP and CHAP.
