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
National Testbed Network in Japan• Provided by National Institute of
Communication Technology (NICT)• GMPLS controlled• Multi-layer (IP + Optical) NMS• 64 access point on every prefecture in Japan• International Connectivity ( US to Chicago, Asia to Thailand and
Singapore)New Trial Services• IPv6• Wide area Ethernet (FE, GbE, 10GE)
All E-NNI nodes are prototype. Interworking among ASON, GMPLS overlay, and GMPLS peer.

UNI and I-NNI
ASON UNI• Modified OIF UNI1.0R2 for supporting LSC (Lambda)
ASON I-NNI• GMPLS RSVP ASON extension
• Generalized_UNI, Call-ID• IETF RFC4203 for OSPF
GMPLS UNI• IETF RFC4208
• Without routing protocolGMPLS I-NNI• IETF RFC3473 for RSVP• IETF RFC4203 for OSPF

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 ……
