Paul Baran proposed two groundbreaking design ideas for the structure and behavior of the ARPANet. Describe these design ideas and the benefits they provide.
What will be an ideal response?
The first of Baran’s ideas adopted for the ARPANet was that of a distributed network, where control is distributed across a large number of machines. This allows for messages to be rerouted along alternate connections when a particular computer or connection fails. Baran’s other idea central to the ARPANet architecture was that of packet-switching, where messages to be sent over the network are first broken into small pieces and then sent independently to their final destination. Advantages of this approach include a more efficient use of the connections, the ability to react to failures and congestion, and improved reliability.
