Find out how modern telephone networks use mathematics to make it possible for a person to dial a friend in another country just as easily as if they were in the same street, or to read web pages that are on a computer in another continent. </div>

<p>Nowadays we take it for granted that someone in England can make a phone call to Australia, or that someone in India can read web pages that are on a computer in Canada.

city in any country in the world.<p><a href="http://plus.maths.org/content/call-routing-telephone-networks" target="_blank">read more</a></p>http://plus.maths.org/content/call-routing-telephone-networks#comments2computer simulationErlang's formulanetworkrouting schemesticky routingWed, 30 Apr 1997 23:00:00 +0000plusadmin2155 at http://plus.maths.org/content
