  1. Migration steps towards future end to end transport networks Juan Fernández-Palacios (jpfpg@tid.es) PHOTONIC NETWORKS (TELEFONICA I+D)

  2. Rationale behind new network architecture Transform TEF Networks to sustain data traffic explosion, in an economically affordable way... …will require a change of paradigm in network architecture… While traffic will experience a 40-50% CAGR, revenues will increase only 1-3%... L2 and optical transport networks IP over DWDM Cost/Gbps Optimum mix of IP, L2 and optical switching Negative Margins Income Positive Margins Source: Cesar Alierta. Investors Conference. Oct. 2009 Traffic 2 Cost effective E2E architectures enabling ultra-high band user’s connections • Getting the best out of the fibre: costs independent from bit rate & distance, • with All-IP characteristics • Use the most cost-efficient technology at each point of the network where needed
