Introduction to GÉANT

• GÉANT is a 10 Gbps Pan-European Network that supports the development activities of the European National Research & Education Networks (NRENs)

• GÉANT was launched in December 2001 and is the successor of TEN-155

GÉANT Topology

• We have currently 19 PoPs across Europe– 2 New PoPs under construction: Israel and

Croatia

• Trunks– 9*STM64 in West of Europe– 12*STM16 in West and East of Europe.

GÉANT now and next steps -- Agnès Pouélé (agnes.pouele@dante.org.uk) 6

GÉANT Topology

• Accesses to GÉANT– 12 connections at STM16 POS capacity– 10 connections <= to STM1 capacity

GTREN is the Global Terabit Research & Education Networkinitiative of DANTE and UCAID to establish an intercontinentalnetwork connecting the various regional research networks.

GÉANT now and next steps -- Agnès Pouélé (agnes.pouele@dante.org.uk) 10

Future Connectivity • EUMEDConnect Project (36 months)

– Part of the Euro-Mediterranean Information Society (EUMEDIS) initiative

– EuropeAid (EC) funded programme

– Beneficiaries are most of the North Africa and Eastern Mediterranean states

– EUMEDConnect aims to provide the necessary network infrastructure

– Will provide intra-regional connectivity and connectivity to GÉANT

– Phase 1 (until end of April)

GÉANT now and next steps -- Agnès Pouélé (agnes.pouele@dante.org.uk) 11

• Caesar project– Same type of project but for South of America

Future Connectivity

GÉANT now and next steps -- Agnès Pouélé (agnes.pouele@dante.org.uk) 12

GÉANT Services

• GÉANT Standard IP Service• Ip traffic from NREN to NREN (About 27

countries)• IP traffic from NREN to Research Peerings

(Abilene, Canarie, Esnet, NII ..)

• Commodity peerings• Commodity IP users to Commercial Peerings

(KPNQwest, Global Crossing, Infonet)

GÉANT now and next steps -- Agnès Pouélé (agnes.pouele@dante.org.uk) 13

GÉANT Services

• Multicast Service– Multicast is enabled for all the NRENs and

Research Peerings

• Replacement of the Managed Bandwidth Service– Premium IP Service (End to End Service for low

Delay, low Jitter, negligible loss).– VPN layers 2

GÉANT now and next steps -- Agnès Pouélé (agnes.pouele@dante.org.uk) 14

GÉANT Services

• Upcoming New Services• Security and Dos attack detection• IPV6

GÉANT now and next steps -- Agnès Pouélé (agnes.pouele@dante.org.uk) 15

GÉANT MULTICAST SERVICE

www.dante.net/nep/GÉANT-MULTICAST/

GÉANT now and next steps -- Agnès Pouélé (agnes.pouele@dante.org.uk) 16

Coverage

•GÉANT is a transit domain for Multicast traffic as well.

•24 NRENs over 27 have explicitly asked for being enabled multicast

•Fully enabled with the Research peerings

GÉANT now and next steps -- Agnès Pouélé (agnes.pouele@dante.org.uk) 17

Access to the Service

• Via the primary access to GÉANT

• Via a GRE tunnel (currently nobody)

• Support of PIM-SM v2 only

• MBGP/MSDP/PIM-SM v2 peering

GÉANT now and next steps -- Agnès Pouélé (agnes.pouele@dante.org.uk) 18

Operational procedures

• Currently under definition

• Goal: fully supported service as Unicast.

• Monitoring of the infrastructure via a set of adapted tools. – Beacon Matrices

• http://beaconserver.GÉANT.net:9999/

• http://beaconserver.GÉANT.net:19999/

– Looking glass => http://www.dante.net/nep/lg/

– Others (volume, MSDP, MBGP …)

GÉANT now and next steps -- Agnès Pouélé (agnes.pouele@dante.org.uk) 19

Operational procedures

• Troubleshooting – Extension of the trouble ticket systems to

multicast incidents – Establishment of a database of Incidents– “Sanctions” for mis-behaving customers ...

IP PREMIUM SERVICEhttp://www.dante.net/sequin/

GÉANT now and next steps -- Agnès Pouélé (agnes.pouele@dante.org.uk) 21

IP Premium Service

• This service which is currently being piloted in GÉANT has the aim to provide international Virtual leased line based on Diffserv.

• The Premium IP service is an end-to-end service (University to University) crossing multiple administrative domains

• It is defined on the basis of the Diffserv Expedited Forwarding Per Hop behavior which is required to offer– Bandwidth, low loss, upper bounded delay and jitter

GÉANT now and next steps -- Agnès Pouélé (agnes.pouele@dante.org.uk) 22

IP Premium model

•Premium IP packets are tagged with DSCP code =46 at the entrance of GÉANT Domain.

•Rate Limitation is applied per aggregate on the NREN’s access, based on the total demanded bandwidth towards the destination.

•Filters are made on two parameters (NRENs networks + DSCP value)

GÉANT now and next steps -- Agnès Pouélé (agnes.pouele@dante.org.uk) 23

IP Premium model

• Admission Control is made manually based on the Sum of bandwidth already booked on the destination access.

• DANCERT (DANTE’s Computer Emergency Response Team)

• Team responsible for defining and implementing DANTE security policy.

• DoS attack service protection• Proactively through rate limiting and anti-spoofing

measures.

• Reactively through DoS tools applying filters and helping report and investigate attacks.

• Assistance in investigating security incidents such as:

• Hacking, Port Scanning, Spam reports
