10 Overview of the Field Trial Network (Jan. Feb. 2006) 7 sites were connected by GbE Links GbE Link(s) Kanazawa Fukuoka Fujimino Musashino Otemachi Kei-han-na Yokosuka 500km Page 10

Interworking among ASON, GMPLS overlay, and GMPLS peer. Page 11

12 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 protocol GMPLS I-NNI IETF RFC3473 for RSVP IETF RFC4203 for OSPF Page 12

13 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 Page 13

18 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 Page 18
