The task assigned to the RAND* researcher Paul Baran in 1964 was to develop a communication system that would survive a Soviet nuclear attack. Baran suggested three possible structures for such a system. It could either be 'centralized', with one central hub and multiple spokes, 'decentralized', with multiple components linked loosely together by a number of weak ties, or 'distributed', like a lattice or mesh. In theory, the last option was the most resilient, in that it could withstand the destruction of numerous nodes, and that was indeed
