network layer
Technical term in computer networking, specifically the third layer of the OSI model responsible for packet forwarding and routing.
ネットワーク層は、データを送信元から宛先まで届ける役割を持つ。
The network layer is responsible for delivering data from the source to the destination.
The transport layer (Layer 4) sits above the network layer and provides end-to-end communication services, while the network layer handles routing between networks.
The data link layer (Layer 2) is below the network layer and deals with node-to-node data transfer, whereas the network layer handles routing across multiple links.
Compound of ネットワーク (nettowāku, 'network') and 層 (sō, 'layer'), a direct calque of the English term 'network layer'.
