Today’s segmented networks
Potential for network optimization through – • Converged network control and operation → functional convergence • Converged transport for mobile and fixed network → structural convergence
Huge variation in terminal equipment and technologies
Simple sharing of aggregation infrastructure –
no common technology base
Different IP edge solutions per technology
Fixed and wireless have separated
control, operation and management

Concluding remarks for structural convergence
Two main approaches can be considered for structural convergence • Access pushed into aggregaLon, based e.g. on NG-‐PON2 including
WDM, or • AggregaLon pushed into access, based e.g. on programmable
DWDM technologies
Network FMC is fundamental for future 5G infrastructure • To achieve end-‐to-‐end management and orchestraLon capabiliLes
