Transcript TEN-155: Europe moves into the fast lane II

TF-NGN
TERENA General Assembly
Roberto Sabatino
Copenhagen, 23 October 2003
The context
• related to the technical developments of GEANT
• influences GN1 yearly technical roadmaps
• related to national networking development
interests
• NRENs
• Universities
• Joint DANTE + TERENA task force
• Chaired by DANTE staff, secretarial support from TERENA
• Open to any individual who can make a voluntary
contribution
• Moving to a forum for discussion on technical
developments
• actual work carried out in sibling projects (SEQUIN,
SERENATE, 6NET..) or GEANT specific WGs (GEANT-v6 )
Activities

•
Premium IP (Mauro -done)
LBE/scavenger (Tiziana, Tim, Nicolas- done)
monitoring and management (Victor, Nicolas - ongoing)
AF based services (Tiziana, Octavio - stalled)
Multicast (Lada - ongoing)
IPv6 (Tim, Stig, Janos.. - ongoing)
Flow analysis (Simon - stalled)
MPLS (Dimitrios..- revived)
Optical Networking (Victor, Michal, Stanislav.. ongoing)
• Router Testing (Ioannis..- done/stalled)
Performance monitoring
• Initiative to specify and build an interdomain
monitoring infrastructure
• To monitor QoS parameters and others (tbd) on an endto-end basis
• using a choice of existing tools
• Principle of each domain making their own
choice of tools used
• front-ended by domain servers and communication
modules
• users (NOC personnel) can retrieve existing
performance data or request a measurement to be
made
• co-operation with I2 initiative
PERT
• Network of people to help improve performance,
proactively
• must be cross-disciplinary (network, applications, OS)
• provide a repository of information of known issues and
solutions
• provide ad-hoc expertise when needed
• structure quite well defined but
• not yet in place and not verified with a user-case
• http://www.dante.net/tf-ngn/pert/
Premium IP management
• Premium IP is available in GEANT but how does a
pair/group of users get it ??
• AAA+resource managers for the future
• Focus on tools for automating information
collection and scheduling
• clarifies roles and responsibilities of DANTE and NREN
staff
• gives immediate feedback on availability of GEANT
resources
IPv6
• Multicast ipv6 pioneered within TF-NGN
• Discussion of broad issues covered - or not - in
6NET
• m6net, application porting/development status,
multihoming, monitoring tools,….
• Discussion of issues specific to GEANT IPv6
deployment
• routing, addressing, interconnections, DNS
Optical Networking
• Exchange of knowledge and experiences
• national initiatives: CH, CZ, PL
• SERENATE study on equipment
• information from vendors (wavium,
• No joint development or hands-on yet
Multicast
• Beacon
• gateway between ipv4 and ipv6
• SSM support
• per-group monitoring
Multi-domain layer-2 VPNs
• MPLS technology is still single-domain
• requirements for circuit emulation services to be
carried interdomain is there and growing
• Atrium, Datatag, DEISA,…
• Currently these are “hacked together” by engineers in
the various domains
• Looking to test manageable solutions for
interdomain operation - drafts martini and
kompella are of interest
• Confirmed effort from DANTE and GRNET
Router Testing
• Focussed on Alcatel OBX 7770
• to co-operate in the development of European
technology and to develop a product targeted at the
needs of the European research community
• Involvement of DANTE + GRNET
• Extensive training, testing, feedback sessions
• goal of deployment on GEANT testbed
• Recent sudden death, just before deployment on
GEANT testbed !
Issues
• Large attendance but not many active people
• a few usual suspects
• Large attendance does not encourage focussed
detailed discussion
• Alternative arrangements tested (break-outs) - but
attendees preferred one single plenary
• too often too ambitious in yearly goals set out
• ideas not followed up by effort from participants
Input to GN1 Year-4 technical roadmap
• Performance monitoring
• PERT
• technology evaluation
• multidomain Layer2 VPNs
• state of art of AAA and resource managers
deployment
What next ?
• Tackle year-4 targets
• Prepare for GN2 (an NA6 activity)
• end-to-end Service Quality (SA3 - provisioning + PERT)
• interdomain performance monitoring (JRA1)
• BW allocation and reservation, covering network
techniques and AAA servers and resource managers
deployment (JRA3)
• Liaise with TF-AACE
• Serve as a forum for discussion of GN2
developments in a wider context
• Propose new JRAs for GN2 in year-2,3,4
