GÉANT2 Vision
Connect. Communicate. Collaborate
• Enable physicists, astronomers and researchers
around the world to share their resources, their data and
their knowledge
• Provide the best possible network connectivity
• High quality, Tailor-Made, Affordable
• Different stakeholders working together to provide a
quality service
• That reaches the users!
• GÉANT2 is not just a backbone network!
How are we getting there?
Connect. Communicate. Collaborate
‘The migration to DF continues apace, as does the
deployment of services which exploit switched networks
and wave division multiplexing’
‘The overall trend is that there is considerable growth [in
capacity] in spite of the fact that on average NRENs
budgets have remained almost static over time’
‘Some NRENs own DF or have IRUs or lease DF and
can decide themselves what technology to use and what
speeds to use on their fibre’

IS DARK FIBRE ‘THE ANSWER’ OR ‘THE
ENABLER’?
What does it mean?
Connect. Communicate. Collaborate
Affordable Access to
Dark Fibre
Higher capacities
available
Reaching more
users
High performance
expected
Greater degree of
Multi Domain
collaboration
Increase in Operational
Efforts = Higher
Operational costs!
Flexibility in technology
used to provide wider
range of services
Increase in
Network
Complexity
What have we achieved?
Connect. Communicate. Collaborate
• Pan-European Hybrid networks
• Advanced IP services
• Lambda and circuit services
• Since 2006 GÉANT2 provides pure wavelengths and GE
circuits to interconnect NRNs across Europe
• Currently ~50 point-to-point connections crossing Europe
• More than 0.3 Tbps capacity dedicated to projects as
DEISA, LHCOPN, Express, Phosphorus and others
• Aiming to provide these services across different world
regions.
Phosphorus – CRC – PSNC

Lessons Learnt
Connect. Communicate. Collaborate
• Each stakeholder may have its own SLAs and
business models
• Extra effort is required in order to set up the interdomain parts of the connection: Multiple technologies
• Domain controlled monitoring tools do not always help
in the end-to-end connectivity supervision
What do we need?:
Multi Domain Operations
Connect. Communicate. Collaborate
• Several GÉANT2 activities are focused in supporting
Multi Domain Operations
• Objective: Delivery and support of multi domain
services as one ‘virtual’ domain from the end user
point of view
• Challenges: Deliver a complex service packaged in
an simple format at an affordable operational cost
Multi Domain Operations -1:
Reducing Operational Costs
Connect. Communicate. Collaborate
• Automated Provisioning of a service
- AutoBahn, DCN,…
• Efficient Delivery of the Service
- Ease fault detection and resolution
- perfSONAR, E2EMon
- Ease communication between stakeholders
- i-Share
- eduGAIN
Multi Domain Operations-2:
Monitoring for IP services
Connect. Communicate. Collaborate
• Hardware and software distributed across Europe (within
GÉANT2 network and the NRNs)
• It gives a global view of the network connectivity and
performance
• Defined set of parameters:
– One Way Delay
– BWCTL
– Link utilization, Link Status, errors, drops
Perfsonar UI

What are others doing….?
Connect. Communicate. Collaborate
Other research networks (Internet2, Esnet)
Together with GEANT2:
- Combined effort in the tools development and
deployment
- Exchange of operational experiences
Common definition of services to users
Definition of global operational processes
Jointly address NOC requirements
Standardize users’ support
What are others doing….?:
Connect. Communicate. Collaborate
Carriers and ISPs: IPsphere example
‘The network and services of the future will be created
by a diverse set of technologies and an equally diverse
set of stakeholders, making the concept of ‘convergence’
truly multi-dimensional’
‘ Coordinating complex network technology resources
across multiple stakeholders is far more complex than
performing the same integration within a single provider’
‘Any future business-technology framework must
address the highest costs: operations’

GÉANT2: Networking Services for
demanding users
Connect. Communicate. Collaborate
• Complex Services
– But seamless to end users
– Bridges operational challenges
– Leads the market
• GÉANT3 project will work towards perfecting this
model and enhance the services
