3. Multi Point VPN in a nutshell
Connecting private network islands
Remote branch offices
Experiments needing exchange
Allows users to keep communication private
Provides multipoint to multipoint connections
Layer 3 (IP) transport
Standardized interfaces
Carriers Carrier (RFC4364)
BGP-LU (RFC3107)
Fills a hole in the multi domain service catalogue
Creating the possiblity for l3vpn opens up for the use of l2vpn using the same techonlogy.

VPNs are configured between the ena PE:s
For point to point VPN an easy setup
For more complex l3ypn and vpls can routereflectors be used.
No need for configuration in the transit networks.
But its not dynamic and automated
So not same use cases as BoD!

7. Organisations & Resources
Currently 14 NRENs have joined
Still counting new NRENs joining
Product Manager: Xavier Jeannin - Renater
Technical lead: Tomasz Szewczyk - PSNC
NORDUNet: Magnus Bergroth
0.05FTE per NREN partner
to cover service pilot phase
updating the service as need arise
cover operational acceptance
Currently 13 NRENs have “committed” to deliver the service
And still counting…..
Current NRENs are:
FUnet, NDN, Deic, DFN, RENATER, GARR, GRNET, GEANT, PSNC, LITnet, HEAnet, CARnet, AMRES, redIRIS.
Product manager: Xavier Jeannin (Renater)
Technical lead: Tomasz Schwezyk (PSNC)
NDN tech lead: Magnus Bergroth
0.05FTE per NREN partner
So involvement is not motivated by big lump sums from the EC

8. Building Multipoint VPN
Multipoint VPN design draft delivered
Experimental test done in network lab &
across all involved NREN networks
Build on strong interface standards already enabled
Identified potential use cases (ITER, PRACE, LHCone, etc.)
Negotiation with additional NRENs wanting to pilot and deploy the service is ongoing
Multi Point Service “awareness” raised significantly throughout GN3

9. Achievements cont Provisioning only done at edges by design!
Thus enabling somewhat quicker establishment of services
Service definitions have been produced
Service structure have been defined
Follows “Best Practice” in place
Technical training of NOC members need to start throughout fall 2013
To ensure that NRENs can actually handle it as a production service end of Y1

10. Last mile Getting all the way to the customer premises Possible
Although:
Regional and campuses are still “in the way”
Have been observed as troublesome in the past
Does not become easier with multitude of end point organisations
Takes a lot of coordination
But that’s life working with customers

11. Thank you Any questions?
