Foreword

This standard rule according to GB/T 1.1-2009 given draft. This revised standard adopts the "Transfer of IP LAPS technical requirements of synchronous digital hierarchy (SDH) on" ITU-TX.85/Y.1321. To Further reflects the integrity standards to ensure interoperability between devices using this standard, the international standards in Annex A, B, C on the positive Article 8, 9, Chapter 10, Appendix Ⅰ on the body of Chapter 11. To differentiate the PPP/HDLC transmission system, increasing the informative Appendix A. For ease of use, this standard also deleted international standards foreword. The standard proposed by the Ministry of Industry and Information Technology of the People's Republic of China. The standard by the China Communications Standards Association. This standard was drafted. Wuhan Research Institute of Posts and Telecommunications. The main drafters of this standard. Yu Shaohua, Meng Ji, Dong Ximing, its Fan Peng. Transfer Synchronous Digital Hierarchy (SDH) on IP technical requirements of LAPS

1 Scope

This standard specifies the protocol model for IPoverSDH simple HDLC (high-level data link procedures); through the service access point mark Identifier (SAPI) provides multiple logical links to encapsulate IPv6, IPv4, PPP and other upper-layer protocol data packets; defines IPover SDH network in a variety of physical interfaces and service primitives used. However, the present standard does not define the LAPS to SDH mapping is not specified LAN (Local Area Network) How to access "IPoverSDHusingLAPS". This standard applies to SDH transmission equipment as a means of public telecommunications network of long-distance network, relay network and access network, applicable to light Fiber optic cable as the basic transmission medium, in principle, can also be used for microwave and satellite.
