Over to

CESNET INTRODUCTION

The e-infrastructure provider in the

Czech Republic for research,

education, and science since 1996

24 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

SUPPORTS A BROAD SET OF APPLICATIONS

Speed-Capacity

(less sensitive to jitter or latency)

Stability

(low jitter,

low latency)

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

SPEED + LOW LATENCY

Example: Real time music collaboration

Miami Brno Brno – Miami

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 amplitude-

modulated signals in mixed networking

environments.

RECAP: ITS ALL ABOUT

MULTILAYER

OPTIMIZATION

● Capex savings up to 25%

versus “layer at a time”

approach

● Basis for complex services

18 ECI Proprietary 18

ALGORITHMS MATTER

● Multiple optimizations

● Lowest first cost

● Survivability

● Multivariate

● Within each layer

● Between layers

● Algorithms are a

source of value

19 ECI Proprietary 19

ULTIMATE GOAL –

AUTONOMOUS

NETWORKS

● Self organizing (like SON

mobile networks)

● Service aware

● Peak efficiency

● Highest levels of Capex

and Opex savings

Need more raw

capacity in sector 9.
