Packet-switched networking model
As presented in the article A Few Fundamentals of Networking Electronically Encoded Data, data must be organized for transmission. Thus, the creation of usable telecommunication packets requires appending a unique header to the message destined to traverse the internetwork. Technically, in order to send messages utilizing IP addressing, a program must prepare IP datagrams through the encapsulation of received datum.
As a potential delivery option, packet switching is an electronically-based communications method for grouping all transmittable data into suitably-sized packets, without exceeding the Maximum Transmission Unit (MTU) allocation. To achieve this goal, packets are routed individually, sometimes resulting in different paths and out-of-order delivery; thus requiring accurate message reassembly.
