In essence, the Third Layer of the OSI Model is the “logistical core” of any networking model. It handles the ‘how’ and ‘where’ of data packet transmission, ensuring that the data reaches its final destination efficiently and correctly, irrespective of the path it takes. Back to Index...
The layer is located between the data link layer and the transport layer as layer 3 in the OSI model. What are the other layers in the OSI model? Besides the OSI network layer, there are six layers in the OSI model: the physical layer, the data link layer, the transport layer, the ...
In the seven-layer OSI model of computer networking, the network layer is layer 3. The network layer is responsible for packet forwarding including routing through intermediate routers, since it knows the address of neighboring network nodes, and it also manages quality of service (QoS), and rec...
Layer 3 switches provide the routing function, which indicates a network-layer function in the OSI model. Layer 3 switches can work at Layer 2 and Layer 3 and be deployed at the access layer or aggregation layer as user gateways. Precautions Switch configurations used in this example apply to...
Layer 3 Switch Layer 3 switches provide the routing function, which indicates a network-layer function in the OSI model. Layer 3 switches can work at Layer 2 and Layer 3 and be deployed at the access layer or aggregation layer as user gateways. Configuration Notes This example uses router ...
layers forming astack. Each layer in the stack is performed in a step-by-step manner: first, moving up the stack during data transmissions and then from the top of the stack down once the data reaches its destination. The layers of the OSI model, including the network layer, are shown ...
they can work together without issue. Therefore, network switches that operate on the different layers of the OSI model are described as Layer 2, Layer 3, or Layer 4 switches. The layer in which a switch operates is determined by how much addressing information it reads as data passes ...
EricConrad, ...JoshuaFeldman, inEleventh Hour CISSP (Second Edition), 2014 Internet Layer TheInternet Layerof the TCP/IP model aligns with the Layer 3 (Network) Layer of theOSI model. This is where IP addresses and routing live. When data is transmitted from a node on one LAN to a nod...
