Expert Solution

Step 1

Primary task of Network Layer

The primary function of the network layer is to move data into and through other networks at Layer 3 of the Open Systems Interconnection (OSI) communication model.
The network layer connects various networks.
This is done by transferring packets to network routers that use algorithms to determine the best routes for traveling data. These are called "virtual circuits."
The network layer relies on the ICMP to manage and diagnose errors to ensure that packets are sent properly. Service quality (QoS) is also available to give priority to some traffic over other traffic.
The network layer may cooperate with connectivity or connectivity networks, but this can only be for a particular type.
