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.

GTREN is the Global Terabit Research & Education Network
initiative of DANTE and UCAID to establish an intercontinental
network connecting the various regional research networks.

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 ([email protected])

Future Connectivity
• Caesar project
– Same type of project but for South of America
GÉANT now and next steps -- Agnès Pouélé ([email protected])

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 ([email protected])
12
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 MULTICAST
SERVICE

GÉANT now and next steps -- Agnès Pouélé ([email protected])
15
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 ([email protected])
16
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 ([email protected])
17
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 ([email protected])
18
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 SERVICE
http://www.dante.net/sequin/
GÉANT now and next steps -- Agnès Pouélé ([email protected])
20
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 ([email protected])
21
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 ([email protected])
22
IP Premium model
• Admission Control is made manually based
on the Sum of bandwidth already booked on
the destination access.

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
