In the TCP/IP model, the layer responsible for delivering packets to their destination is the Internet Layer. This layer is also known as the Network Layer in the OSI model.
The Internet Layer provides logical addressing and routing services to enable communication between hosts on different networks. It is responsible for encapsulating data packets into IP datagrams, which contain the source and destination IP addresses. These IP datagrams are then forwarded by routers to their destination based on the destination IP address.
The Internet Layer uses the Internet Protocol (IP) as its primary protocol to provide connectionless, best-effort delivery of packets across the network. It also provides fragmentation and reassembly services to handle packets that are too large to be transmitted on a particular network segment.
The Transport Layer, on the other hand, is responsible for providing end-to-end communication services for applications. It uses protocols such as TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) to establish a connection between hosts, provide reliability and flow control, and multiplex multiple applications onto a single network connection.
Therefore, while the Transport Layer plays a critical role in ensuring reliable end-to-end communication between applications, it is the Internet Layer that is responsible for delivering packets to their destination across the network.
