Relevance of MUPBED for NRENs

  • Harmonisation/convergence of “telecom operator” and NREN

solutions

  • Network architecture work, selected theoretical investigations
  • Leading edge control plane solutions:

– Focus on IETF GMPLS and ITU ASON approach, including multi-domain inter-working – Driving standardisation

  • Work on “application – network” inter-working

– Applications (requirements, interface, selected trials in test bed) – User groups (within and outside the MUPBED consortium)

  • Extended field trials for selected solutions: Set-up and operation of

European scale test bed

  • Collaboration with GEANT2 Project, TF-NGN

NRENs attitude towards MUPBED technologies

  • PSNC, Poland:
  • Migrating to IP/MPLS
  • Highly interested in using MUPBED developments for on-demand bandwidth provisioning
  • Red.es, Spain:
  • Currently IP/MPLS-based network and manual L2VPN configuration
  • Demand on bandwidth and P2P connectivity is only increasing
  • Completed the upgrade of L2 (up to 4x10 GbE between nodes), L2 VLANs + VPNs are now provided to

customers

  • Decided on L1 upgrade (WDM), most likely deployment by 2008
  • Near future deployment of ASON/GMPLS for automatic bandwidth provisioning, participates in

AUTOBAHN testing of GMPLS

  • GARR, Italy:
  • already using IP/MPLS, DWDM, 10 Gb/s links (SDH, Ethernet)
  • interest in ASON/GMPLS as a tool for traffic engineering and optical equipment (L1) management
  • Actual deployment in a part of the production network on a time scale of 1-2 years
  • DFN, Germany:
  • Currently using DWDM up to 160 x 10 Gb/s, Ethernet (95% of links are GbE, including some 10GbE)

and SDH, VPN and best-effort IP

  • Follows the MUPBED developments in the ASON/GMPLS control plane
  • Most likely to start a GMPLS-based intra-domain pilot in the future

Jogging your memory about MPLS

  • Multi Protocol Label Swapping
  • Traffic Engineering extensions

– E.g. RSVP with MPLS TE extensions for signaling – E.g. OSPF with MPLS TE extensions for routing

  • Label has link local significance
  • No data plane / control plane separation

  • Generalized MPLS
  • Data Plane (DP) and Control Plane (CP) separation
  • GMPLS TE extensions for signalling (RSVP), routing (e.g. OSPF)
  • Link Management Protocol (LMP) – new protocol

– Informs RSVP-TE and OSPF-TE about the data plane

  • Technology dependent labels (SDH, fiber port, wavelength etc)

The User to Network Interface - UNI

If you are allowed to signal the provider network this can be seen as a sort of bandwidth / VPN on demand, i.e., a service provisioning tool I-NNI - Interior Network to Network Interface

UNI RSVP agent

  • IETF or OIF RSVP-TE
  • Packet labeling

ASON or GMPLS Network domain

UNI

command line client

mngt protocol

  • Two flavours: IETF UNI and OIF UNI

– OIF: UNI-C (Client) and UNI-N (Network)

  • No routing information
  • Both based on IETF RSVP-TE
  • Differences like

– LSP Session / Call and Connection segments – TNA address usage – Etc

This part could be integrated into an application, i.e., a service provisioning tool (which was actually done by DTU)

Summary of MUPBED technical results

  • UNI Tests in MUPBED

– OIF UNI RSVP-TE Agent tested ok – IETF UNI RSVP-TE tested ok

Include Ethernet in GMPLS due to possible resource de-optimization

  • Design and setup of an GMPLS Ethernet network

was successfully established

– LSP setup and teardown was successfully shown, i.e., working signalling and routing

  • Design and setup of an GMPLS three layered (MPLS,

Ethernet and optical) network was successfully established

– LSP setup and teardown has been partially successful – Much work remains in this area
