Connect. Communicate. CollaborateGÉANT2 Vision

• 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!

Connect. Communicate. CollaborateHow are we getting there?

‘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’?

Connect. Communicate. CollaborateWhat does it mean?

Affordable Access to Dark Fibre

Higher capacities available

Increase in Network

Complexity

Flexibility in technology used to provide wider

range of services

Increase in Operational Efforts = Higher

Operational costs!

Reaching more users

Greater degree of Multi Domain collaboration

High performance expected

Connect. Communicate. CollaborateWhat have we achieved?

• 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.

Lessons Learnt

• Each stakeholder may have its own SLAs and business models

• Extra effort is required in order to set up the inter-domain parts of the connection: Multiple technologies

• Domain controlled monitoring tools do not always help in the end-to-end connectivity supervision

Connect. Communicate. Collaborate

What do we need?: Multi Domain Operations

• 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

Connect. Communicate. Collaborate

Multi Domain Operations -1: Reducing Operational Costs

• 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

Connect. Communicate. Collaborate

Multi Domain Operations-2: Monitoring for IP services

• 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

Connect. Communicate. CollaborateWhat are others doing….?

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

Connect. Communicate. Collaborate

What are others doing….?:

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’
