What are some WAN protocols?

The key WAN protocols that are in use are Asynchronous Transfer Mode (ATM), Broadband Access, Frame Relay, Point-to-Point Protocol (PPP), Synchronous Optical Network (SONET), Synchronous Digital Hierarchy (SDH), X.

Which of the following are data link layer protocols?

Some of data link protocols are given below :

  • Synchronous Data Link Protocol (SDLC) –
  • High-Level Data Link Protocol (HDLC) –
  • Serial Line Interface Protocol (SLIP) –
  • Point to Point Protocol (PPP) –
  • Link Control Protocol (LCP) –
  • Link Access Procedure (LAP) –
  • Network Control Protocol (NCP) –

What are datalink protocols?

Data-link protocols specify how devices detect and recover from such collisions, and may provide mechanisms to reduce or prevent them. Examples of data link protocols are Ethernet for local area networks (multi-node), the Point-to-Point Protocol (PPP), HDLC and ADCCP for point-to-point (dual-node) connections.

What is the role of data link layer?

The data link layer is responsible for multiplexing data streams, data frame detection, medium access, and error control. It ensures reliable point-to-point and point-to-multipoint connections in a communication network.

Which is the main function of data link layer?

The data link layer is the second layer in the OSI Model. The three main functions of the data link layer are to deal with transmission errors, regulate the flow of data, and provide a well-defined interface to the network layer.

What is asynchronous protocol?

Asynchronous communication is the transmission of data between two devices that are not synchronized with one another via a clocking mechanism or other technique. Data is exchanged in blocks of a fixed number of bits that are bracketed by a START and STOP bit.

Where are data link protocols located in OSI?

The data link protocols operate in the data link layer of the Open System Interconnections (OSI) model, just above the physical layer. Framing − The stream of bits from the physical layer are divided into data frames whose size ranges from a few hundred to a few thousand bytes.

Which is the most common data link layer?

Popular Data Link Layer Protocols ARP Address Resolution Protocol ARCnet ATM CDP Cisco Discovery Protocol CAN Controller Area Network

What do you need to know about WAN protocols?

Like the two other WAN protocols mentioned in this article, HDLC is a Layer 2 protocol (see OSI Model for more information on Layers). 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.

Which is an example of a data link protocol?

Data-link protocols specify how devices detect and recover from such collisions, and may provide mechanisms to reduce or prevent them. Examples of data link protocols are Ethernet for local area networks (multi-node), the Point-to-Point Protocol (PPP), HDLC and ADCCP for point-to-point (dual-node) connections.
