ATTRIBUTES OF THE INTERNET

The Internet was developed to support the transfer of data traffic (packets) between computers and workstations with the use of adaptive routing features, see Table 1-2.

An Internet protocol (the Transmission Control Protocol, TCP) at the receiver can be used to reorder the packets into the proper sequence. The other possible result of adaptive routing is that the arrival rate of the packets at the receiver may vary; some packets may arrive ...
