NET LAYER

NET LAYER

1. The applications and network services of a terminal can communicate with the applications and services that are executed in another terminal.

2. NETWORK LAYER PROTOCOL

   • THE NETWORK LAYER IN COMMUNICATIONS
     • THE NET LAYER
       • The network layer or the OSI 3 layer provides services to allow terminals to exchange data in the network.
     • NETWORK LAYER PROTOCOLS
       • network layer protocols that are usually implemented: Internet Protocol version 4 (IPv4), Internet Protocol version 6 (IPv6).

3. CHARACTERISTICS OF THE IP PROTOCOL

   • IP ENCAPSULATION
     • To encapsulate the transport layer segment or other data, IP adds an IP header.
   • IP CHARACTERISTICS
     • It provides only the functions necessary to send a packet from an origin to a destination through an interconnected network system
   • IP WITHOUT CONNECTION
     • IP has no connection, which means that a complete exclusive connection is not generated before sending the data
   • IP MINIMUM SERVICE DELIVERY
     • The IP protocol does not guarantee that all packages that are sent, in fact, are received.
   • INDEPENDENT MEDIA IP
     • IP works independently of the media that carries the data in the lower layers of the protocol stack.
