GRNET3 . . .

a Gigabit dark fiber network for Research & Education

. . .

GRNET3 country-wide dark fiber

• Basic characteristics

– 35 PoPs – Fiber optic pair:

• 8410 Km
• MANs

Athens+Thessaloniki

• DF local loops in 33

cities (to be delivered)

GRNET3 IP architecture

• GRNET3 continues to provide IP services:

– IP routers installed at major Greek cities – IP routers connected with 2,5G PoS framed lambdas implemented via GRNET’s DWDM equipment – Clients aggregated to the local GRNET3 routers by using 1GbE framed lambdas implemented via GRNET’s DWDM equipment – For clients with high requirements (called Power Clients – PC) and traffic overcoming 1Gbps, an IP aggregation architecture is implemented

• 10Gbps uplinks are aggregated to a major PoP using DWDM and then

served at the IP layer

GRNET: a human network as well

• Members of the academic and

research community

• Core network Task force
• Staff from GRNET HQ
• National and EU structural

funds groups

– Development of GRNET3 action

GRNET NOC

• Collaborative development

and management of the network

• Basic and advanced

services

– Computing – Storage – Cloud – Media

GR-IX (Greek Internet Exchange)

• Neutral Multi Gigabit

Greek ISP interconnection

• Local traffic stays in

Greece

GRNET Media Services

developed and operated under the VNOC scheme

• video on-demand
• live streaming
• multicast channels

targeted to institutions, not end-users directly

vod.grnet.gr

multicast channels

pilot projects

• iptv.grnet.gr
• VideoGRID
• e-movie

iptv.grnet.gr

• GUnet project
• Content aggregation portal
• Many platforms, players, transports (multicast/unicast), formats (transcoded)

• Objectives

– Educate

• providing content related to digital video production theory and common practices
• providing experts’ help

– Promote

• university students’ creativity in the area of video production
• self-expression through producing short films

– Build a shared interest community and attract original content – Motivate

• undergoing short film production contest among university students’

– Productions up to 10 minutes; Free context; Several prizes – Winner decided 50% from audience, 50% from an experts’ in film production group

• Initial thoughts

– for an annual web short film festival – for hosting several thematic video production contests

• Current status

– 250 registered users with an average increase of 5 registrations/day – several daily visits from registered and unregistered users – 15 submissions, expected to double or triple until the contest’s deadline (20 Apr) – several comments provided to each submission indicate high interest and an active community

GRNET4

Next generation of GRNET network and services

GRNET4: Network infrastructure evolution

• Robust services over interconnected networks

– Federated model – Federated management (topology exchange, monitoring, security and control)

• Network of the future

– User-controlled virtual networks

• Technologies

– Transmission: ROADMs (incl. control plane) – Transport: Protocol agnostic switching (e.g. T-MPLS) – Connectivity: IP

• Service Oriented Architecture

– Control functionality embedded in middleware, exploiting AAI

Goals

• An environment for the development of new technologies and research
• “Intelligent” backbone network with dynamic adjustment capabilities for increased traffic

requirements

• Operational optimization, management functions
• Resources directly accessible by users
• Extension of the geographical coverage
• Advanced media services
• Interconnecting R&D institutions with significant digital content (museums, libraries),

content production and distribution services

• Interconnecting non-R&D institutions for the exchanges of educational, cultural and public-

interest content

• Soft actions for the widespread use of new services by the country’s R&D community

Diverse network infrastructure Computational infrastructure Advanced services

Research networking for Science

• Computational and network infrastructure :

– High Energy Physics – Meteorology – Astronomy (processing data from distributed telescopes) – Medical data exchange and processing – Earth observation – World climate change observation – Medicine research – Economic market research – ….

• Service for Data-Intensive Science: secure repositories for use by scientific

groups

– Storage and processing of large data sets

• Integrated Collaborative Environments

– Portal, Wiki, Instant Messaging System, videoconferencing

• Virtual Research Environment

– Desktop-based or web-based applications for developing and sharing workflows – Networking environment for sharing and finding experiments, protocols, workflows, experimental results, scientific data, papers, technical reports – Management of multimedia material

• Service for sharing access to scientific instruments, sensors etc.

Services for Scientific Research sharing & collaboration

Large scale and high-definition videoconferencing services

– Adaptive web-based videoconferencing service

• Automatically adapts to different network conditions (end-to-end) and

endpoint capabilities

– Interactive applications in HD

• Multicast-based
• Equipment for production and playback for high-fidelity, (larger than) HD,

low-latency interactive applications

Advanced services for managing and distributing academic media

• AAI-supported services for multimedia production and

distribution by and for all members of the academic & research community.

• Applications for processing, archiving, indexing and

distributing media.

• Use of the computing and storage infrastructure of GRNET for

processing and archiving of digital media
