GÉANT community

• The GÉANT community consists of Europe’s National Research and Educational Networks (NRENs) working together

• We focus on the collaborative effort to innovate the service portfolio, creating more advanced services

• We consider world-wide collaboration of R&E Community very important

Strategy and Innovation in CEF Networks


Importance of CEF Networks • Customer Empowered Fibre (CEF) networks are

Facilities for network services development and operation, shared globally for support of research, innovation and education

• CEF Networks are in principle Integrated Facility for experimentation and production services

• CEF Networks are used as large field test bed for equipment and service vendors

• CEF Networks are instrument supporting research in various fields of science and upgrading competitiveness of research teams



Contributions to Development • The global economy has suffered from recession and is

recovering too slowly, but some resources are available

• Public funding of R&E Community

• Dark fibres under municipalities, regional authorities, governments or EC projects control (not available on free market – for example fibres along fuel pipelines)

• Contributions from CEF Networks’ users (research projects, industry innovation projects etc.) for advanced services

• Technology for multivendor fibre spectrum sharing (Spectrum as a Service, SpaaS) enables CEF Networks’ cost savings



ROWANet - Network of Highland region

• Regional Dark

fibre network

collaborating with

CESNET

• Lighted with

Czechlight

equipment

• Using also cost-

effective single

fibre bidirectional

transmission

• Example for other

regions and cities



CEF Networks R&D Strategy • Challenge is to enlarge user group providing services not available on

the market and increasing income

– Opportunities for higher revenue are expected for example in development

of remote real-time sensing or control (Machine to Machine

Communication etc.), especially as a service for providing security

improvements in industry

– Dark fibre last mile connection to users’ premises for significant new user

to user applications

• Challenge is also to achieve savings

– Progress in technology, especially availability of equipment for multivendor

fibre spectrum sharing in transmission systems, enable cost-effective

solution of transmission systems

– Overlaying fibre footprints are not needed

• Solution is known and verified, but wide area (e.g. continental)

implementation needs long time work – with this Strategy



Network as a Spectrum Service • Network as a Spectrum Service (NaaSS) is concept of end to

end allocation of spectrum for experiments or special services

• For such purpose, Cisco and Czechlight (CL) transmission systems provide photonic services (end to end all-optical lambdas)

• For applications requiring more advanced usage of fibre spectrum we use CL transmission systems (we have unlimited access to fibre spectrum)

• single fibre transmission

• L-band transmission

• T/F transmission

• hard-real time sensing for additional reliability

• etc.



CL lines available to adaptation



Two physically diverse last miles are

needed for good availability of

important scientific or industry

equipment

• risk of fibre cuts especially in cities

• observation of past is not feasible

(data from sensors and some other

equipment are lost, if not

transferred and recorded)

Lighting of last miles for new

application types should be flexible

(for example by Spectrum as a

Service) – best solutions for Leading

Edge Applications are still not known

Service instead of equipment • Fast and frequent adaptation for experimentation is

crucial requirement in CEF Networks

• Service instead of transmission system hardware property is needed – similar to cloud approach => LaaS - Lighting as a Service is required

• Competition of LaaS suppliers enables to negotiate a good contract

• We are not dependent on single vendor equipment development road map

• CESNET started with LaaS in 2002



Steps to LaaS deployment • Collect experience with LaaS implementations

– LaaS documentation of about 1000 km of single fibre and fibre pair

lines lighting exists

• Elaboration of LaaS specifications for typical requirements in NRENs

collaboration (strongly vendor independent), for example

– e2e lambdas needed

– international lambdas via CBFs as R&E Networks Service

– e2e photonic services

– frequency bands kept free for other purposes

• Pre-procurement of LaaS pilot (prototype) implementations in

collaboration with interested suppliers

• Certification of specified LaaS deployment for reputable suppliers

• Procurement and deployment of LaaS by R&E Networks – individually

or collectively as needed

There is a lot of capacity in fibres still • Present 100G systems 8Tbps in 35nm of C band

• Vendors are offering also L band now, together almost 90nm

of whole 400 nm spectrum available in single mode fibre

• Next gen 22Tbps in 35nm of C band (400Gbps over 75GHz, DP-16QAM)

• Vendors are already considering capacity shared as service on photonic

level, e.g.: K. Grobe: „Flexible Spectrum-as-a-Service“, TNC14

Prague, September 15th, 2014 8th CEF Networks workshop


Present 100G transmission system

• Design is usually without compensation of chromatic

dispersion (no native 10G, only coherent 100G), it makes

sub 100G transport very expensive

• Upgrade to 400G not so easy - very expensive and reach

lowered: example numbers 600km@400G vs

4500km@100G http://blog.infinera.com/2014/01/06/coherent-

technology-you-cant-have-too-much-of-a-good-thing/#more-1073

• Moving‚ Big Data Centres‘ to 400G transponders or

400G@access and 4x100G@backbone? (IEEE P802.3bs

400Gb/s Ethernet Task Force is working since Mar 2014) http://www.research.att.com/articles/featured_stories/2013_05/201305_

Specific issues • A significant part of the CEF Networks user community

requires services that are not available or affordable

from commercial providers. Identifying observed or

anticipated user needs should be elaborated into a

vendor-independent specification.

• Cost savings in transmission layer and increasing

income from users were identified as main interests of

many NRENs. The transmission layer (fibres, lighting

equipment and digital services) is responsible for about

65% of the overall cost of the GÉANT network.

Transmission layer cost is also dominant for NRENs.



27

Why to improve transmission

layer for R&E Community • Advanced transmission is necessary prerequisite for

competitive services

• Transmission layer is too expensive, resulting in lack of

funding for rest of activities

• Transmission systems are not sufficiently adaptive to R&E

requirements – tailored mainly for telecom operators

• We are very far from optimal solution still, because vendors

transmission technology development roadmaps were not

oriented to needs of R&E community

• Situation is changing: CEF Networks are usefull for support

innovation in industry (collaboration, testing etc.)



28

How to improve transmission

layer used for R&E Community • We should specify requirements of R&E Community (from

local networks to global) in advance and use some suitable

method of PCP for PPI: Pre-Commercial Procurement for

Public Procurement of Innovation

• We should keep independency of any single vendor

development road map, R&D Community needs must be

strongly preferred

• We should keep open the opportunity for new vendors,

including Photonic industry

• In summary: Innovation in tendering is necessary
