What is point to point protocol?

Explanation

Define Point to Point Configration
  • Point to point (P2P) protocol is a data-link layer communication protocol to establish direct connection between two nodes.
  • Communication protocol connect computers to remote networking services including internet service providers.
  • P2P protocols tunnel Internet Protocol or other network Layer 3 data between two directly connected nodes over a physical connection, or over a direct link.
  • Widely used for the heavier and faster connections necessary for broadband communications.

Advantages of P2P:

  • Defines format of the frame to be exchanged between the devices.
  • Defines link control protocol.
  • Defines mechanism of network layer data encapsulation in data link frame.
  • Provides error detection.
  • Allows IP address to be assigned at the connection time i.e.. dynamically- a temporary IP address can however be assigned to each host.
  • Also defines how two devices can authenticate each other.
