A last kilometer issue in Madrid Serenate Workshop 17-18 September 2002, La Hulpe Jesús Marco (marco@ifca.unican.es) Consejo Superior de Investigaciones Científicas IFCA (Santander) SPAIN

The Issue Points: 

The Issue Points CIEMAT is a large spanish scientific installation in Madrid (Spain), with national andamp; international projects… with a low bandwidth (2 Mbps) and saturated connection to the NREN RedIRIS central site (Geant node) is also in Madrid, at a couple of kilometers How to improve the link? Organizational questions Solving the problem

CIEMAT: 

CIEMAT Research Public Institution attached to the Ministry of Science and Technology (MCyT) Fields of Activity Fossil Fuels Nuclear Fission Energy Nuclear Fusion HEP Physics Renewable Energies Environmental Quality andgt;1000 people (andgt;500 scientists) Central site in Madrid city: 20 Ha. , 71000 m2 in 27 buildings

CIEMAT (campus level): 

CIEMAT (campus level) andgt;20 departamental servers andgt;650 desktops Supercomputing infrastructure Network: 4km optical fiber + cable 23 people in IT department 2Mbps

Slide5: 

RedIRIS Site (NREN) CIEMAT 3 km MADRID Regional/Metropolitan European Interconnect National Three Level Model

Slide6: 

  Traffic (cars) in Madrid at 6.30 am Traffic (cars) in Madrid now (8.30 am) Many complains from users (in particular those with international projects)

Organizational questions: 

Organizational questions NREN in Spain: RedIRIS takes care of the National Backbone In process of upgrade to 2.5Gbps, 622,155 Mbps redundant topology 17 autonomies, each one with a RedIRIS connection node, should take care 'inside' its domain of the 'campus' connection CIEMAT in Madrid, but ... central organization was a Ministry of Industry institution Now a MCyT institution The 2 Mbps link paid by CIEMAT (20keuros/year) So, new link cost on CIEMAT...

Solving the problem: 

Solving the problem CIEMAT solution: Discussion and collaboration with NREN: Antonio Mollinedo(CIEMAT) met Esther Robles(RedIRIS) last year (in annual RedIRIS meeting) CIEMAT has opted for a direct fast-ethernet link (now being contracted, ready by end of the year) Good possibility in a metropolitan range Administrative/Legal solution: via a genomic project Reasonable Cost: 36Keuros Other possibilities discussed: New optical ring (paid by Madrid Community) joining all academical institutions, and through RedIRIS site New fast links for Universities, CIEMAT close to the Universidad Complutense de Madrid campus UAM (was also at 2Mbps, at 30 km): now radio-link

Conclusions: 

Conclusions Disclaimer: This is only my 'experienced' user point of view (in particular regarding Administrative issues) Short Distance makes this problem Outstanding In fact, the short distance factor (inside metropolitan area) gives more possibilities for connection… Organizational issues do weight! Legal/Administrative(/Political?) issues Quite difficult to solve some times (even if cost is not high) Collaboration/Support between Final Users (Feedback and Project Support) Campus Level Network Responsible andamp; Institution NREN Many thanks to Esther Robles and Antonio Mollinedo for the information
