Outline

JGN II: National Testbed Network in JapanKei-han-na Info-Communication Open Laboratory

Field Trial of Interworking of ASON/GMPLS domains• Nationwide scale in Japan

• 4 operators 6 ASON and GMPLS domains.• GbE over Lambda Switch Capable Network Elements.

• Signaling interworking with ASON E-NNI• Reachability information exchange among domains.• RSVP signaling over multiple domains.

• ASON to ASON• ASON to GMPLS• GMPLS to ASON• GMPLS to GMPLS

Conclusions


JGN II Network

Kei-han-na Info-Communication Open Laboratory Overview

Established at 2003• To establish a global-standard info-communication

sectors in Japan “Kansai” region through industry, academia, and government collaboration.

• National Institute of Communication Technology (NICT) provides rental lab space and rental research facilities.

• IP routers, TDM-XC• Access point to the JGN II network

No financial support from National Agency to the Interoperability Working Group.

Goal of the Interoperability WG (2003-2005)

Verification for inter-connectivity of new inter-Carrier or inter-AS interface (E-NNI).

• PJ3/4: GMPLS E-NNI protocols.• Demonstrated at MPLS 2005.• Reported in OFC2006 PDP47, iPOP2006 1-2, OIF Workshop

• PJ2: 10GbE over OTN technologies.Cooperative development from Japan, proposal for international standardization.

• ITU-T, IETF, and OIF.Extended GMPLS connectivity experiment and construction of the open site.

• PJ1/4: Multi-vendor GMPLS interoperability field demonstration reported in OFC2005 PDP40.

Inter-Carrier E-NNI Implementation

ASON E-NNI signaling protocol (RSVP-TE)• Modified from OIF E-NNI 1.0 for supporting LSC.• Pseudo single session for GMPLS domains was supported

Routing protocol (BGP-4)• Reachability information (addresses and adaptation)

exchange among BGP peers.• Proprietary BGP-4 extension

Extension for I-NNI routing protocol (OSPF)• Local reachability information exchange between OSPF

and BGP-4.• Proprietary OSPF/BGP-4 extension

• Summarized reachability information redistribution• Proprietary OSPF extension

Conclusions

A field trial of ASON and GMPLS interworking was conducted on a nationwide scale.

Seamless call set up over multi-carrier domains over the distance of 1,000 km or more was successfully achieved.

Demonstrated interworking operation is expected to relax the choice of the adopted network model for carriers.

We can accelerate deployment of ASON and GMPLS networks.• But more work is required ……
