Panamerican Advanced Studies Institute Mendoza, Mayo 2005 Advanced Networks in Latin America and Argentina: available infrastructure

Panamerican Advanced Studies Institute Mendoza, Mayo 2005

Advanced Networks in Latin Americaand Argentina: available

infrastructure


Agenda

• Grids: needs for advanced networks

• Network Infrastructure in Argentina

• Network Infrastructure in Latin America

• Grids: regional initiatives


GRIDs: characteristics

• Colaboration between institutions in different cities, countries or continents

• Particularly useful for large countries like Argentina

• Equipments and resources to be shared• Based on Advanced Networks


Why Advanced Networks?

• Need for bigger bandwidth• Quality of Service: different kind of traffic,

priorities, response times• IPv6: addressing, security, flexibility, mobility• Multicast:

– optimized bandwidth for audio and video transmisions

– possibility to build p2p architecture involving many sites


Available Infrastructure

• RETINA: Research and Education Network of Argentina– Advanced backbone in the central region of the

country

• AMPATH: Internet2 connection• CLARA: Cooperación Latinoamericana en

Redes Avanzadas– Available Infrastructure for regional

connectivity and communications to the rest of the world


What is RETINA?

“Red TeleINformática Académica”

• NREN of Argentina since 1990• Around 60 institutions of R&E• Managing the network of the 36 Public

Universities• Connected to Internet2 since 2001 (through

AMPATH) and initial member of CLARA since 2002


RETINA: main facts

• International representation of the NREN since 15 years ago

• Project always running during that period• RETINA is not a user of the resources, the

services are available to the R&E community• Main role together with other NREN from LA

in associative projects like Clara, Alice, LACNIC, ENRED, etc.

RETINA + RIU


Avanced Network in Argentina

• December 2001: RETINA gets connected to Internet2 being part of the AMPATH project

• First institutions connected: UBA, UNL, UTN, SMN

• Initial link of 45 Mbps

• Native Multicast and IPv6


Objectives• To connect RETINA to other advanced networks• To promote the access to that kind of networks

from the R&E institutions of the public and private

sector of the country• To make available to the R&E community the new technologies and applications that are already in use in main countries• To support the development of new applications that are still not possible in the actual Internet


AMPATH

• DS3 (45 Mbps) for each NREN

•Global Crossing – FIU agreement

•Duration: 3 years

AmPath


• Access to Abilene (Internet2)

• Access to Startap and transit to Europe, Canada and other advanced networks.

• Active since 2001 for Chile, Brasil and Argentina.

AMPATH


In the National scene

• Problem: internal capilarity• Buenos Aires and the suburban zone have

very good fiber infrastructure• Other main cities like Córdoba, Rosario,

Santa Fe, Mendoza have many carriers/providers

• Main problem: to extend the good connectivity to the rest of the country (monopolies, bad infrastructure).


Network availability

High

Medium

Low


Strategies for augmenting national connectivity

• Need of a high speed R&E backbone• Negotiation with carriers to be able to

use available excess bandwitdth already installed.

• Agreements for joint work• There are already some PoPs inside the

country available

Backbone key facts

• International link of 45 Mbps extends to the central region of the country

• More than 70% of the R&E activity of Argentina is in that zone

• It’s a starting point: it has to be extended to cover the other zones

• Important: each city in the backbone gets the same access conditions like Buenos Aires (services, costs)


Backbone features

• Initial capacity: 45 Mbps. Potential upgrade to 155 Mbps

• Native IPv6 available

• Native Multicast

• QoS in the core and in the access

• International link: 90 Mbps


Backbone features

• Agreement with Impsat to have a backbone in the central region of Argentina

• Negotiation with other providers to extend the backbone to North and South

• Already available 45 Mbps:– Mendoza, Cordoba, Rosario, Santa Fe– Other PoPs will be available on demand


IPv6 availability

• RETINA connected in native mode to AMPATH; soon to CLARA

• Institutions will have native mode connectivity

• Production addressing from LACNIC: 2001:1418::/32

• Addresses asigned to the institutions that ask for them

Multicast - Concept

• Mechanism to transmit the same stream of data to multiple receivers in an efficient way

• Unicast: one stream for each receiver

• Broadcast: data gets replicated to all the points in the network

• Multicast: only the minimum BW gets wasted, only the interested receivers get the data


Multicast - Concept


Multicast - Concept


Multicast

• Native Multicast available with AMPATH and CLARA

• Multicast will be available in all the PoPs of the backbone

• Very few institutions have implemented multicast service until now

• We will give support to the institutions that want to implement it


Quality of Service

• Need for guaranteeing different kind of traffic quality of service:– Videoconference– VoIP– Remote management of instruments in real

time– Data transfers

• They will co-exist at the same time in the Network


Quality of Service

• Parameters to take account:– Latency– Jitter– Packet loss

• QoS in the backbone but also in the access (institutions)

• WG of QoS integrated by RETINA and institutions

Network sustainability

• CLARA coordinates ALICE project in LA

• Total cost of ALICE project is 12.5 Millions Euros in 3 years

• 10 Millions Euros funded by the European Comission by Interconnection Initiative within @LIS

• 2,5 Million Euros will be provided by LA NRENs as cofinancing

• After 2006 finantiation will depend on use and a better balance of international bandwidth costs


Grids: initiatives in the region

• RETINA: infrastructure to give support to research projects (PAV, others)

• Proposal to ALFA funding to train researchers and technicians (RETINA-UNCOMA-CRIBABB-UNPA)

• CLARA: EELA proposal to the European Comission


Support Infrastructure

• PAV: computational and access GRIDs deployment

• Make use of RETINA’s advanced backbone

• Join groups of researchers from different institutions of the country

• Will favor the integration and research in ICTs


ALFAGRID

• 4 institutions in Argentina:– RETINA, CRIBABB, UNCOMA, UNPA

• Coordinator: Universidad de Cantabria• Other countries:

– España, Italia, Francia, Chile, Mexico, Brasil, Venezuela

• Training in GRIDs oriented to researchers and technicians (support)


EELA Project

• E-infrastructure shared between Europe and Latin America

• Joint project betwen EU-LA presented to EC IST

• Extend to LA Grid technology and infrastructure developed in EGEE

• Period: 2006-2007, in case of being approved• Take advantage of the already developed

Advanced Networks: GEANT, CLARA


EELA: objectives• To build an interoperable infrastructure

between EU and LA• Identify joint research & scientific applications

between EU and LA• Encourage participation in new projects at a

national and international level• Promote participation in relevant forums of

grid computing• Contribute to make researchers aware of grid

computing


EELA: participants

• CLARA and the NRENs of the participating countries

• Countries:– España, Italia, Portugal– Argentina: UNLP– Brasil, Chile, Cuba, México, Perú,

Venezuela• CERN


Conclusions

• There exists Advanced Network infrastructure for GRIDs support in LA and Argentina

• Working actively in the development and growing of that infrastructure

• New applications and services are promoted by different organizations

• GRIDs in Argentina are still to be developed• We expect to collaborate in the dissemination

and use of these new technologies
