Multi-Protocol Label Switching Transport Profile( MPLS-TP) ring protection is one of the key technologies of MPLS-TP network which is still ongoing researched under a Joint Working Team( JWT) of ITU-T and IETF. Through investigating existing ring protection schemes,a novel “Fast Wrapping” ring protection switching mechanism and corresponding distributed implementation method are proposed. Using the “Fast Wrapping” switching mechanism and corresponding distributed implementation method,the data loss can be decreased during the protection switching. At the same time,the protection group volume will be easily increased, the operator of network management will be simplified and the equipment reliability will be improved due to the distributed implementation method.
