2 Necessity is the mother of invention Make a virtue of necessity ECI Proprietary 2 2

3 NECESSITY: OVERCOME PHYSICAL LIMITATIONS ON FIBER OPTIC BANDWIDTH GROWTH Now operating at the Shannon Limit Transmission needs to choose: Faster and shorter Longer and slower Forces new approaches to increase capacity Capacity (speed) Pre - Shannon Limit Shannon Limit Distance Prior to reaching the Shannon limit optical transmission could be optimized to go faster and further ECI Proprietary 3 3

4 INVENTION: REAL TIME MULTI LAYER OPTIMIZATION Advanced algorithms + Real time control + Agile packet-optical transport technologies Elastic (agile) packet-optical network OTN Switching Real-time E2E control Optimized algorithms Open source & interfaces Packet Switching ODUflex Flexible Ethernet L2-L3 L1-L2 Adaptive Rate TX Real-time OSNR Flexible Spectrum CDC-F ROADMs L0-L1 ECI Proprietary 4 4

5 AGILE PACKET-OPTICAL TRANSPORT TECHNOLOGIES Technology Optimize Fiber Capacity Create Complex Services L2-L3 Packet Switching Statistical multiplexing Policy management L1-L2 Flex Ethernet OTN w/ ODUflex Match bandwidth of Ethernet client and network interfaces Ethernet client choice OTN Switching Maximize fill (grooming) L0-L1 CDC ROADMs Flexible Spectrum Agile Transceivers Real time OSNR Multivariate optimization: signal (coding) channel (filter width) optical path Bandwidth on Demand Dynamic service restoration ECI Proprietary 5

6 VIRTUE: COMPLEX MULTI-TIER BANDWIDTH SERVICES Creates user choice Outputs after playing with selector controls Estimated Turn-up Time 3.0 hours Cost $175 /day Maximizes revenues Relies on resource sharing User experience 2 similar to ordering cloud services 1 Port 1 5 Madison Ave, NY, NY, 3 rd floor Port Morris Ave, Hoboken, NJ Gbps Service Envelope Selector Ports Selector Committed Information Rate Gbps 1.75 Excess Information 1.25 Rate Speed Selector Immediate 1 Minute Gbps Hour 0.50 CIR Protection ECI Proprietary 6 6

9 CESNET INTRODUCTION The e-infrastructure provider in the Czech Republic for research, education, and science since public and 2 state universities, 54 Academy of Sciences research institutes Advanced DWDM optical and IP/MPLS infrastructure connected to GÉANT and GLIF 6400 Km of fibres (100G DWDM) Cross border fibres connecting Austria, Slovakia, Poland

10 SUPPORTS A BROAD SET OF APPLICATIONS Stability (low jitter, low latency) Speed-Capacity (less sensitive to jitter or latency)

11 HIGH STABILITY High speeds cannot solve all challenges. New applications like Accurate Time Transfer or Ultra Stable Frequency Transfer are here CESNET service to connect and compare atomic clocks in Praha and Wien CESNET service to monitor stability of containment of a reactor pressure vessel in the Temelín nuclear power plant Remote control of instruments like telescopes Essentially Alien wavelengths Low and stable jitter and latency are the key

12 SPEED + LOW LATENCY Example: Real time music collaboration Brno Miami Brno Miami

13 ACHIEVING HIGHER speeds Demonstrated interoperability between ECI Apollo with 400G flex-grid blade and Czech Light open DWDM system: 2000 km DP-16QAM 200 Gb/s signals for 20 years of CESNET High bit rate traffic easily transported as Alien Wavelengths over the CESNET production network. Verified coherent and legacy amplitudemodulated signals in mixed networking environments.

16 ECI 200G FLEX GRID PERFORMANCE Tested by Telecom Italia 4 x 37.5GHz super-channel for effective 800G! 8 flex grid WSS cascade 800G flex grid super-channel Results Strong system performance (OSNR, Flex-grid cascading) 200G 200G 200G 200G Easy configuration & control ECI Proprietary 16

17 RECAP: ITS ALL ABOUT MULTILAYER OPTIMIZATION Capex savings up to 25% versus layer at a time approach Basis for complex services ECI Proprietary 17 17

18 ALGORITHMS MATTER Multiple optimizations Lowest first cost Survivability Multivariate Within each layer Between layers Algorithms are a source of value ECI Proprietary 18 18

19 ULTIMATE GOAL AUTONOMOUS NETWORKS Self organizing (like SON mobile networks) Service aware Peak efficiency Highest levels of Capex and Opex savings 400G blade en route! Need more raw capacity in sector 9. Issue PO. ECI Proprietary 19 19

20 Tightly Coupled A NEW PARADIGM Decision making Classic SDN Human Autonomous Networks Machine Analytics Reports Feed algorithms Algorithms Recommend action Take action Dynamic restoration Predetermined or Best Effort Fluid Multitier bandwidth services Initial stages Central concept Incremental revenues $ Capex/Opex savings $ $$ $$ ECI Proprietary 20

21 STAYING AHEAD OF THE CURVE Benefits TODAY Multilayer optimization of agile packetoptical technologies Classic SDN Autonomous Packet-Optical Networks TOMORROW Jump S-Curves and remove the driver from the car to maximize responsiveness and savings Time ECI Proprietary 21
