In the last RTFM we saw how IP packets are transmitted across the network. Here, we tackle Ethernet and see how packets are encapsulated and used. To explain fully the way in which IP packets are used ...

The wireless infrastructure is likely to remain a circuit-switched, time-division multiplexed technology for much of the next five to seven years. Even after the transition to third-generation (3G) ...

The use of IP for audio and broadcast transport applications has gained increasing attention as the quality of service (QoS) of packet switched networks continually improves. The lure of reduced costs ...

A digital network technology that breaks up a message into smaller chunks (packets) for transmission. Unlike circuit switching in traditional telephone networks, which requires the establishment of a ...
