DISCUS – A solution to the 3 major problems facing future broadband networks:
1. Financial - The cost of network provision:– Large mismatch between revenues and the cost of providing capacity.
2. Environmental -The huge growth in power used by the worlds telecommunications networks.
3. Social - The need to avoid a “digital divide”. – Provide the same service capability for customers in sparse rural
communities as dense urban areas.– With minimal government subsidies!
An end to end architecture for a high performance, economic and low power future broadband network
Summary of technical achievementsLR-PON is a key enabler for the required architecture change.
• It enables the flat core which has been shown to be the lowest cost solution for the future network
• TDMA+DWA provides future proof bandwidth allocation to all users.
• DWA solutions analysed and preferred solution without needing AMCC or synchronised quiet windows identified.
• LR-PON protocol channels can co-exist with 100Gb/s DP-QPSK s .
• 40Gb/s upgrade using bit-interleaved protocol.
• Technology gaps investigated: burst-mode EDC, burst mode FEC, tuneable filter and low cost tuneable laser, burst mode FEC (not in DISCUS) demonstrated.
• SOA amplifier options can open up other optical windows on same LR-PON fibre infrastructure.

11Concertation Meeting, Brussels ‐ 01/03/2016
Benefits offered by FOX‐C solution
The ability to transparently adapt lower rate tributaries into elastic super‐channels• The developed switching technologies with record sub‐1GHz resolution allow low rate
tributaries to be added/dropped transparently with minimum spectral guard band• Concept is proven particularly beneficial for cases like inter‐data centre communications and
extended metro‐access connections to core where a large number of lower rate 1‐10 Gbpstributaries are present.
The resource optimization of the current infrastructures• Extensive network evaluation and comparison results shown that FOX‐C switching scheme
can extend the blocking‐free lifetime of current networks and therefore alleviate the immediate need for further investments in network capacity.
The direct compatibility with the mixed‐line rate EON approach• The two stage node design offers a combination of the typical EON approach and the added
benefits of FOX‐C multi‐granular switching approach• The HSR switching feature is practically an added feature to an elastic switch and is
implemented as an additional switching stage in the FOX‐C node
The significant cost and power consumption savings• The savings originate from the adoption of all‐optical traffic grooming and are particularly
evident when compared with the OTN‐based electronic approach and for increased traffic loads as expected in the near future.
The STRAUSS project focuses on the design, development and integration of: Highly integrated and scalable software defined optical transceivers supporting
bandwidth variable multi‐flows for flexible Ethernet transmission based on OFDM and DMT.
Flexi‐grid DWDM optical circuit switching node architectures for long haul transport.
Cost/energy efficient and extremely fast‐performing switching node architectures based on variable‐capacity and fixed‐length optical packet switching technology for access and aggregation networks, and OPS/OCS integrated interface.
A virtualization layer for dynamic and on‐demand partitioning of the optical infrastructure, offering virtual optical networks .
Control plane architectures based on either legacy (e.g. GMPLS) and new (e.g. OpenFlowbased) approaches for the control and management of virtual optical networks.
A service and network orchestration layer for the interworking and coordination of heterogeneous control planes and transport technologies to offer end‐to‐end Ethernet transport services.

Part 2: Updates of the progress H2020 optical projects
ACINO: Application‐centric Transport Network Orchestration
Objective: differentiate the service offered to each application at each layer of the transport network
Basic use‐case: app‐centric IP/Optical service provisioning• Example: two applications
– Tactile Internet (very‐low latency, high availability and reliability) – VM migration (very high bandwidth)
• Compilation of intents into two different multi‐layer application‐centric services, e.g.:
– Tactile Internet: setup dedicated optical channel, fast IP survivability– VM migr: re‐use existing IP tunnel, slow optical survivability
• Network orchestrator config IP and optical devices– Open‐source development with ONOS framework
• App‐centric and orchestration approaches can be extended to 5G transport (i.e., multiple techs in Xhaul)

Design and implementation of SDN based controller for Spatial ‐Spectral resource allocation
Motivation
ICT 6 – 2014: Smart optical and wireless network technologies
“Address the limitations of current optical transmission technologies”
Reducing the margins improves efficiency and reduces or postpones investments BER issues (soft‐failures) arise and there are no current mechanisms to solve
Optical networks are designed under worst case assumptions using “End‐of‐life margins” Equipment (fibers, amps) ageing Interference (Nonlinear impairments) Maintenance interventions
Motivation
ICT 6 – 2014: Smart optical and wireless network technologies
“Address the lack of dynamic control and management of optical network resources within and across operator's domains for lower cost and more flexible use of resources”
Physical layer monitoring information is barely used in the network lifecycle Planning‐provisioning inefficiencies are never corrected Soft‐failures are treated as black or white
Limited knowledge of the failure cause, and only one control remedy available: protection
Flex‐grid and tunable transceivers provide vast optimization options, but cannot be efficiently configured without physical layer feedback
ORCHESTRA proposes to close the loop between physical layer and the control plane
Interacting with the physical layer enables a more dynamically controlled network that can be used in a more flexible and efficient way
Vision
An optical network has to be observable before it canbecome controllable and be subject to optimization
• ORCHESTRA proposes to close the control loop by enabling physical layer observability
• Observability relies on the coherent receivers that are extended, almost for free, to operate as software defined impairment optical performance monitors (soft‐OPM)
• Physical layer information of single or multiple soft‐OPMs is used to take better optimization decisions
• Re‐acting dynamically on the network to increase its efficiency
1. Develop an advanced DSP‐based physical‐layer multi‐impairment monitoringalgorithm suite
2. Develop a holistic approach to Quality of Transmission (QoT) determination inall network lightpaths using information from distributed software‐definedoptical performance monitors (soft‐OPMs) and advanced correlation algorithms
3. Develop a hierarchical control and monitoring infrastructure providing activeand passive monitoring capabilities with rapid and effective reactions todegradations and failures
4. Develop dynamic optimization procedures for fault management and networkre‐optimization
5. Lower the barriers of resource sharing among operators’ domains through theefficient monitoring of alien lightpaths and accurate physical layer SLAs
6. Demonstrate dynamic and highly efficient flexible network operation enabledby software‐defined optical performance monitoring
ORCHESTRA vision: “An optical network has to be observable before it can become controllable and be subject to optimization”
