Answer

True

Explanation

The Network layer is responsible primarily for logical addressing, routing, and forwarding packets from source to destination.

When a message is divided into multiple packets, the Network layer can treat those packets independently, particularly in a connectionless datagram network. Different packets may take different routes and may arrive out of order.

The Network layer does not provide the end-to-end relationship, sequencing, acknowledgements, or retransmissions required for reliable delivery. Those functions are normally provided by the Transport layer when a reliable transport protocol such as TCP is used.

Therefore, the statement that the Network layer does not establish a relationship among different packets of the same message is True.

Final answer: True.
