Network layer of OSI model does not establish any relationship among different packets of same message. (Write True or False)
Network layer of OSI model does not establish any relationship among different packets of same message. (Write True or False)
In the OSI model, the Network Layer primarily provides connectionless packet forwarding based on the destination address. As a result, it does not establish and maintain a relationship among different packets that belong to the same higher-layer message; each packet is routed independently by the network. This independence is characteristic of IP-like network-layer behavior, whereas the Transport Layer (e.g., TCP) is responsible for connection-oriented delivery, ordering, and reliability.
Therefore, the statement is: True.
Key idea: Network layer routing is about getting each packet to the next hop; it does not keep per-message state to relate packets.
type="tip" title="How to Answer the True/False" content="If the statement says the OSI network layer does not keep relationships among packets of the same message, that matches the typical connectionless, packet-by-packet service model of the network layer. Answer: True."
type="warning" title="Common Confusion: Network vs Transport State" content="Routers (network layer) generally forward packets independently. The end-to-end “conversation” (ordering/reliability) is handled by the transport layer (e.g., TCP), not the network layer."
Reasoning Path to the True/False Answer
- 1Step 1
The statement refers to the Network Layer.
- 2Step 2
It performs routing and forwarding on a per-packet basis.
- 3Step 3
The network layer typically does not keep per-message state to link packets from one message together.
- 4Step 4
End-to-end relationships like connection-oriented delivery are the transport layer’s responsibility.
- 5Step 5
Since the relationship among packets of the same message is not established by the network layer, the statement is True.
Where Packet Relationship Is Actually Built
Independent packet forwarding
Network LayerEach packet is routed based on addressing/routing; no message-level reassembly relationship is guaranteed here."
End-to-end relationship
Transport LayerTCP-like service creates an end-to-end connection and can reorder/reassemble data correctly."
