A telecommunications capacity crunch has been widely predicted for the near future. Demand for communications capacity will greatly exceed the ability to aggregate and route signals in a simple network with a modest number of links (currently of single mode fibre) between network nodes and routing devices within these nodes. This will not be an immediately devastating crisis resulting in an abrupt absence of resource but rather, if un-combatted, will force a significant change in network provider’s business model. In a post crunch environment, it will either be impossible to offer increased bandwidth services at a price effectively only adjusted for inflation. This will result in either bandwidth pricing, demand management, service prioritisation or rationing, and impacting the “net neutrality” of the internet.
