Study Notes
Network Layer Introduction
- The Network Layer is the 3rd layer of the OSI model and is responsible for managing host and network addressing, sub-networks, and internetworking.
Layer-3 Functionalities
- The primary focus of devices that work on the Network Layer is routing.
- Routing tasks include:
- Addressing devices and networks
- Populating routing tables or static routes
- Queuing and forwarding data according to quality of service constraints
- Internetworking between different subnets
- Delivering packets to destination with best efforts
- The Network Layer provides both connection-oriented and connectionless mechanisms.
Network Layer Features
- Quality of service management
- Load balancing and link management
- Security
- Interrelation of different protocols and subnets with different schema
- Different logical network design over the physical network design
- L3 VPN and tunnels can be used to provide end-to-end dedicated connectivity
- Internet protocol is a widely deployed Network Layer protocol that enables end-to-end communication between devices over the internet.
