Market drivers
o Exponential growth of data rate require-ments (e.g. 10 Mbps within 3 years)
o New services with symmetric (e.g. peer-to-peer, gaming) and asymmetric (e.g.VoD, streaming) characteristics
o Service differentiation through Quality ofService
o Platform convergence towards digital IP-based
