Study Notes
Network Layer in the OSI Model
- The network layer is responsible for packet forwarding and routing through intermediate routers.
- The main function of the network layer is to provide logical addressing, routing, and congestion control.
- The network layer responds to service requests from the transport layer and issues service requests to the data link layer.
- The Internet Protocol (IP) uses connectionless communication, which means it does not establish a dedicated end-to-end connection before transmitting data.
- Every host in a network needs to have a unique IP address to be identified.
- The network layer is responsible for routing data between devices on different networks.
