Network layer буюу Сүлжээний түвшин нь компьютерын сүлжээний OSI загварт тодорхойлогддог сүлжээний үйл ажиллагааны хийсвэрлэлтийн түвшин. Layer 1 (Physical): Actual hardware sits at this layer. It transmits signals over media. The TCP/IP model, sometimes referred to as a protocol stack, can be considered a condensed version of the OSI model. Layer 1 (Network Access): Also called the Link or Network Interface layer. This layer combines the OSI model’s L1 and L2. Apr 06, 2014 · Layer 3 provides the network’s routing and switching technologies that create logical paths known as virtual circuits (VC), which are used for the transmission of data between network nodes. The main functions of Layer 3 include routing and forwarding, as well as internetworking, addressing, packet sequencing, congestion control and further
What devices are used in each layer of the OSI model? - Quora
Jul 10, 2020 · Layer 3, or Network Layer, switching takes place when a packet arrives on one router interface and is forwarded on to another. Protocols that may be present in the Network Layer include the Datagram Delivery Protocol (DDP), Internet Control Message Protocol (ICMP), Internet Group Message Protocol (IGMP), and Internet Protocol Security (IPsec). OSI Layer 3 - Network Layer. 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 recognizes and forwards
