On the ‘net: ATM Asynchronous Transfer Mode, or ATM, was widely seen as a compromise technology that would provide the best circuit and packet switching in a single technology. Data would be input into the network in the form of either packets or circuits. The data would then be broken up into fixed sized cells, which would then be switched based on a fixed label-based header. This would allow hardware to switch the cells in a way that is like circuit switching, while retaining many of the advantages of a circuit switched network. In fact, ATM allowed for both circuit- and packet-switched paths to be both be used in the same network. @ECI’s LighTALK Related Posted in ON THE NET ← Short Take: Nerd KnobsOn the ‘net: Math in Network Engineering →
