There were many GMPLS interoperability trials. However, most of them reported the successful results only. How to set up a trial network and how to test it was generally not discussed. In this paper, as a kind of tutorial, detailed GMPLS field trials in the National Institute of Information and Communications Technology (NICT) Kei-han-na Info-Communication Open Laboratory, Interoperability Working Group (WG) are reported. The interoperability WG is aiming at the leading edge GMPLS protocol based Inter-Carrier Interface that utilizes wide-bandwidth, cost-effective photonic technology to implement IP-centric managed networks. The interoperability WG is a consortium for researching the GMPLS protocol and advancing a de facto standard in this area. Its experimental results, new ideas, and protocols are submitted to standardization bodies such as the International Telecommunications Union-Telecommunication standardization sector (ITU-T), the Internet Engineering Task Force (IETF), and the Optical Internetworking Forum (OIF). This paper introduces the activities of the interoperability WG; they include a nationwide GMPLS field trial using the JGN II network with multi-vendor, multi-switching-capable equipment and a GMPLS multi routing area trial that used a multi-vendor lambda-switching-capable network.<\/p>\n\n \u5ca1\u672c\u5148\u751f\u3068\u5c71\u4e2d\u5148\u751f\u306e\u3001\u3051\u3044\u306f\u3093\u306a\u60c5\u5831\u901a\u4fe1\u30aa\u30fc\u30d7\u30f3\u30e9\u30dc\u306b\u304a\u3051\u308bGMPLS\u76f8\u4e92\u63a5\u7d9a\u5b9f\u9a13\u306b\u95a2\u3059\u308b\u8ad6\u6587\u304c\u3001\u96fb\u5b50\u60c5\u5831\u901a\u4fe1\u5b66\u4f1a\u82f1\u8ad6\u6587\u8a8c\u306b\u63a1\u9332\u306b\u306a\u308a\u307e\u3057\u305f\u3002 \u8ad6\u6587\u306b\u3064\u3044\u3066\u306f\u3001\u4ee5\u4e0b\u306e\u3068\u304a\u308a\u3067\u3059\u3002 \u30bf\u30a4\u30c8\u30eb: “GMPLS i … \u7d9a\u304d\u3092\u8aad\u3080 \u5ca1\u672c\u5148\u751f\u3068\u5c71\u4e2d\u5148\u751f\u306e\u3051\u3044\u306f\u3093\u306a\u30aa\u30fc\u30d7\u30f3\u30e9\u30dcGMPLS\u76f8\u4e92\u63a5\u7d9a\u306e\u8ad6\u6587\u304c\u4fe1\u5b66\u4f1a\u82f1\u8ad6\u6587\u8a8c\u306b\u63a1\u9332\u3055\u308c\u307e\u3057\u305f<\/span>
