  1. GMPLS interoperability testin Super SINET Shoichiro Asano The National Institute of Informatics Hirokazu Ishimatsu Japan Telecom Co., Ltd.

  2. Super SINET • Ultrahigh-speed network intended to develop and promote Japanese academic researchers by strengthening collaboration among leading research institutes. • Operated by The National Institute Informatics (NII) which is an independent administrative corporation. • Besides the academic network, there is the research project studying the next generation optical networks.

  4. Research project • Focus on optical technologies • Physical layer • 40G bit/s transmission • Dispersion compensation • Optical regeneration • Control plane • GMPLS interoperability • GMPLS LSP recovery

  5. Testbed • Cisco 12400 series routers • Calient 3D-MEMS-based PXCs • Mitsubishi bascule-type PXC • NEC DWDM systems • 30-km-long Installed fiber

  7. Bascule type optical switch • 16x16 switching matrix • 0.3 ms switching speed

  8. What we have achieved • All-optical end-to-end path rerouting • PXC, WDM, and IP router integration • Full set of generalized multi-protocol label switching (GMPLS) protocol suite • RSVP-TE, OSPF-TE, LMP and LMP-WDM • Two types of PXCs • 3D-MEMS, bascule type optical switch • Installed cable as one of data links • Four vendor interoperability

  15. Conclusion • Interoperability of PXCs, WDMs and IP routers has been successfully demonstrated using an installed fiber. • Two types of PXCs; bascule type optical switch, 3D-MEMS • Four major GMPLS protocols have been interoperated. • RSVP-TE, OSPF-TE, LMP, and LMP-WDM • Successful rerouting of all-optical path hasbeen performed by the signaling via out-of-band control plane network.
