Foreword

Structure GB/T 21645 "Automatic Switched Optical Network (ASON) technical requirements" standard is expected as follows.

--- Part 1. Architecture and general requirements;

--- Part 2. Terms and definitions;

--- Part 3. Data Communication Network (DCN);

--- Part 4. Signaling Technology;

--- Part 5. User - Network Interface (UNI);

--- Part 6. management plane;

--- Part 7. automatic discovery.

This part of GB/T 21645 Part 7.

This part of ITU-TG.7714.2005 "General transmitting entity automatic discovery" and G.7714.1.2006 "SDH and OTN networks Automatic discovery agreement "non-equivalent, combined with the development of the domestic situation.

The following sections of this part of the technical content and ITU-TG.7714 coordinated.

--- Chapter 4 correspond G.7714.2005 Chapter 6 - Chapter 10, and adds features and frame contents are automatically discovered;

--- Chapter 5 corresponds G.7714.2005 of Chapter 11 and Chapter 12;

--- Appendix A correspond G.7714.2005 Appendix I.

The following sections of this part of the technical content and G.7714.1.2006 harmonized.

--- Chapter 6 correspond G.7714.1.2006 Chapter 5 - Chapter 11, and 6.2 adds the OTN OTS/OMS/LAD mechanism OCh layer;

--- Appendix B, Appendix C and Appendix D, respectively G.7714.1.2006 Appendix I, II and Appendices Appendix VI.

In addition, the Section 7 and Appendix E also refer to the IETF, OIF and other relevant International Organization for Standardization and automatic link management protocol Recommendations found.

This section of the Appendix A, Appendix B, Appendix C, Appendix D, Appendix E is an information appendix.

This part is proposed by the Ministry of Industry and Information Technology of the People's Republic of China.

This part of the jurisdiction of the China Communications Standards Association.

1 Scope

This section GB/T 21645 specifies the automatic transmission entity Switched Optical Network (ASON) generic auto-discovery function, framework, process and found messages, and synchronous digital hierarchy (SDH) and Optical Transport Network (OTN) networks and automatic discovery mechanism based on multi-protocol communication standard Record exchange (GMPLS) Link Management Protocol (LMP) and the like.

This section applies to ITU-TG.803 defined synchronous digital hierarchy (SDH) transport network and ITU-TG.872 defined Optical Transport Network (OTN).
