Why open lighting for Research and Education Networks?

Freedom in REN design (fibres are not sufficient) Use full advantage of advanced products of photonic industry by

programmable devices Very cost effective, comparing to legacy approach Availability of transmission parameters to monitoring and

management (impairment detection etc.) Fully open to improvements during network life cycle Research, development and testing of new network principles is

not limited to upper layers High speed transmissions using multiple lambdas (for example

5x20 Gb/s)

Open lighting is feasible

Photonic components are commercially available (transmitters, receivers, amplifiers, TFBGs, semiconductor switches...)

Interconnection of components and packaging into industry PC chassis and kits are simple

FPGA kits and designs are available for demanding applications Concept was proved by deployment in CESNET2 network,

devices are very reliable Development of UNIX-based management of photonic

components has good results (using experience with open software development in universities and RENs)

Possibilities of shaping the future (and further development of open lighting concept)

Legacy research networks Past approach to research networks design and deployment:

– lease SDH/SONET from telco operator

– buy or lease equipment from one of dominant vendors

Main disadvantage: dependency on telco operator and equipment vendor during network life cycle, resulting mostly in slow innovation and high costs (in contradiction with research networking mission). Nevertheless, work for profit is not mistake of telco operators or equipment vendors.

This means our requirements concerning research networks design, deployment, operation and innovation should be improved

DWDM NIL 8 x 10 Gb/s over 224 km

All devices have been installed only at the end points of the line in Brno (CZ) and Wien (AT) and no in-line elements have been deployed.

Nothing In Line (NIL) approach has been used and according to our knowledge, 8 times 10 Gb/s over 224 km of dark fibre is the longest NIL distance that has been reported for any research or ISP network.

The main advantage of NIL solution is represented by lower capital and operational costs and increased reliability.

Enabled by advanced photonic technology

The fibre pair from Brno to Vienna has been equipped with CLA PB02 optical amplifiers, developed as a part of optical research activities of CESNET.

Chromatic dispersion of G.652 optical fibre has been compensated by new compensating elements – Fiber Bragg Gratings (FBG).

Terminal routers are equipped with Xenpak DWDM pluggable optical transceivers.

First two companies have started CLA manufacturing. First ISP has started usage of CLA.

Remember The Internet had its origins in the world of research and universities and

research networks are still the most advanced part of the Internet Close collaboration of universities and research institutions is success factor

for research networking (used mostly also for education, health care etc.) Research networks

– are an important source of Internet innovation– are largely funded from taxpayers’money– contribute to information technology innovation and deployment, and

hence to economic prosperity The research networking environment drives the development of the Internet

– It develops new technologies and services– It produces university graduates who expect advanced information

technology applications Consortiums of universities and research institutions (country-wide, region-

wide, project-wide, continent-wide etc.) are responsible for inception, design, management and maintenance of research networks

Applied high end networkingrelevant research field

Iterative steps from research to wide application: research of networking (what principles and technologies fits to user needs) -

by studies, experiments in lab, experiments in networking facilities (national, regional, world-wide), evaluation of testing by advanced users, ...

building of high end production networks and services (for research and education) - NRENs, continent-wide (GEANT2, NLR, I2), world-wide (partial projects of US and EU now)

deployment of successful results in non-research networks (enterprise, municipality, commercial, ...) - CEF Networks etc.

deployment of successful results in development of products for networking - influenced by user needs (procurement, market), design on demand, …

26The Quilt's 2007 Spring Member Meeting and Workshop

How to reach the high end

1. By collaboration with researchers able to use high end networks or services world-wide (high demanding, real time, ....)

2. By functional improvement of networking services (software for control plane, AA, mobility, IPv6, ...) - cyclic adaptation to new HW needed

3. By use fibres and full power of optronics and microelectronics devices (lighting, Tuneble FBG, semiconductor optical switching, optical processing, FEC, OEO conversion on chip, PIC, FPGA, ....) - huge improvement of speed and/or other parameters

4. Go to affordable edge of high technology possibilities (reliable financial resources needed)

We need all points above.

Research networks vision Research network life-cycle is from inception, design, management,

maintenance and upgrades up to end of life (replacing by new research network)

Consortium is responsible for network life-cycle. Realization of above tasks can be fully or partially outsourced, if working capacity or special knowledge is missing in consortium (and funding is sufficient).

Consortium should maintain own ability to immediately use networking research results, results of fibre footprint development and new types of electronic and photonic products.

Important requests are:– Fibres (including last mile) dedicated to research network are crucial– Freedom of improvement and independency on vendors (mixed vendor approach)– Ability to quick return and correct design (including re-tendering etc.)– Interoperability of devices and Multisourcing (MSA) – Pre-procurrement with fibre providers and electronic and photonic industry

(including collaboration on proposals of standards) Customer Empowered Network (CEF) concept aims to support this vision

Steps to vision Acquiring first dark fibre (324 km) for CESNET in 2000, STM-16 transmission Using new advanced photonic products for 189 km STM-16 transmission without any

in-line devices since 2002 (i.e. mixed vendor network design) Bratislava (SK) – Brno (CZ) GE since 2003, now DWDM NIL over 190km Cieszyn (PL) – Ostrava (CZ) GE since 2004, now DWDM n x 10 Gb/s Brno (CZ) – Wien (AT) since 2006, DWDM NIL 8 x 10 Gb/s over 224 km Nothing-in-line (NIL) approach, where possible and practicable

Upgrade of dark fibre lease service to lit fibre lease service is prepared for 4 dark fibre lines of CESNET network now (experiment with partial outsourcing)

– no return to SDH or lambda lease for research networks – fibre provider will deliver more service (for example lease, installation and maintenance of

DWDM lighting devices designed and managed by research network

For offer of full outsourcing see new announcements:– Offerings include but are not limited to: network architecture and design, installation, staging

and implementation services, order management and asset tracking, and 24 x 7 x 365 operations support.

Collected objections and answers about photonicsO: Task of NRENs is not to develop High end networking technology instead of vendors.A: Vendors are directed by standards, procurements and market. NRENs need to acquire and

verify knowledge used for RFI and procurement (requests of new technology, influencing vendors). This is research and practical verification of principles and guaranty of independence on vendors rather then development of equipment.

O: Low cost technology is not interesting for high end networking.A: Not in general.  High end networking should be affordable. Advanced technology means

improvement of some parameters, for example speed, costs, reliability, dimensions, power consumptions, etc. So it depends on the case.

O: Low cost technology is not interesting for rich countries.A: In principle, the opposite is true: rich countries are rich, because do not waste resources so

much. Low cost technology is not interesting only for some companies and some managers temporarily.

O: High-end networking technology is not affordable for developing countriesA: Not in general. Some advanced technology brings cost effectiveness (remember

microelectronics story)O: We are not allowed to use of our funding and capacities for charitable support of high end

networking technology deployment in less developed countries (with explicit exceptions).A: Deployment of high end networking technology is in some cases simpler in countries, where

new networks are built. In such cases it is research collaboration on pilot deployments, not support.
