Which layer of the OSI model is responsible for packet forwarding?

The Network layer of the OSI model is responsible for packet forwarding. This layer takes care of routing packets across the network from the source to the destination based on their IP addresses. It determines the best path for data transfer and is responsible for logical addressing and packet forwarding, which involves moving packets from one network to another through various gateways or routers. At this layer, protocols such as Internet Protocol (IP) operate, facilitating the transfer of data packets and ensuring they reach the correct destination. The Network layer also handles congestion control and fragmentation, enabling different network architectures to communicate effectively. Other layers of the OSI model have different responsibilities. The Application layer caters to end-user services and applications, the Transport layer ensures reliable data transfer and segmentation for error recovery, and the Data link layer is responsible for node-to-node data transfer and frame formatting. Each of these layers plays a crucial role in networking, but it is the Network layer that specifically handles the forwarding of packets through the network.
