EU FP7 DISCUS: flat optical transport networks
• End-to-end network architecture using LR-PONs directly connected to a flat optical core
• Dimensioned to scale economically under sustained user bandwidth growth of >1000x
• Targeted order of magnitude reduction in network cost and energy consumption wrt BAU
• SDN metro-core node with optical switch fabric enables architecture on demand provisioning

Smart city networks: some challenges…
• Complexity
o Great diversity of traffic demands
o Tidal flows of data usage across
metro area
o Creating user perception of infinite
bandwidth
• Integration
o Vision requires close integration of
many network technologies
o Needs open frameworks and
partnerships to benefit from SME
innovations
• Resilience
o Making a smart city network both
open and secure

…and opportunities• Dynamic provisioning of dark fibre circuits
o Outside broadcast streams at major events
o Collaborative UHD video production
o Ultra-low latency Inter-datacentre/HPC/storage
connectivity
• 5G fibre/wireless network integration
o CPRI wireless fronthaul bandwidths from
baseband unit pool can range up to several
100 Gb/s
o Optical cross-connects can help allocation of
BBU cloud resources to areas of peak demand
in radio access network
o All-optical switch data latency is <20ns with
zero delay jitter – no impact on fronthaul timing
o Longer term potential for direct RF over fibre
links to distributed antennas
