It has the task of delivering [[data packet]]s from the source [[host]] to the destination host. For this purpose, the Internet Protocol defines methods for encapsulating data from an upper layer protocol into packets, and addressing systems so that the packets can reach their destination. For outgoing packets, the Internet Protocol selects the nearest intermediate Host and transmits the packet to it using appropriate Link Layer drivers. For incoming packets, IP captures the packets and passes their payload up to the appropriate Transport Layer module. |
