Network intelligence - The shifting balance

As the century changes we are moving from traditional voice telecommunicati ons based on circuit-switching to broadband multimedia communications based on packet-switching. The role of intelligence in networks is changing as a result. The balance is shifting from intelligence in the network to intell igence at the edge-in both terminal equipment and in server-based applicati ons. It is not clear-cut, however, and the balance will shift within changi ng boundaries of technology, cost and regulation.
