[0004] In a static OTN network, 1+1 protection is usually configured for services, and the backup channel is exclusively used to ensure protection switching <50ms, and no additional services can be configured; in an intelligent network, ASON or SDN OTN systems reserve shared protection resources for service rerouting and recovery. The service protection level can be divided into: permanent 1+1, 1+1 rerouting, 1+1 no protection, rerouting, no protection, but it does not have the "no protection, preemptible" like SDH iron-level business Insufficient use of network resources in the mechanism of using shared protection resources to issue additional services

Embodiment Construction
[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are invented. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0034] At present, the service levels of SDN-based OTN stipulated and developed by the International Standards Organization and various manufacturers in the industry include: permanent 1+1, 1+1 rerouting, 1+1 unprotected, rerouting, unprotected, etc. , Preemptible” service levels are defined and developed, and there is no mechanism for using shared protection resources ...

The embodiment of the invention provides an SDN-based service oversending method and system in an OTN. The method comprise: using an OSS for cooperating with an SDN-based OTN to execute service oversending of an additional service, and if it is judged that a fault occurs in the SDN-based OTN and other services except the additional service cannot be recovered, the additional service is discarded.The OSS cooperates with the SDN-based OTN to carry out extra service oversending; and when the SDN-based OTN has a fault and other services except the additional service cannot be recovered, the additional service is discarded, so that the over-sending of the additional service in the SDN-based OTN is realized, the network resources are fully utilized, and the security of the original service in the SDN-based OTN is ensured.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of optical transport networks, and more specifically, relate to a method and system for service oversending in an SDN-based OTN. Background technique [0002] In the Synchronous Digital Hierarchy (SDH) era, the transmission network has two "service oversending" mechanisms to improve the resource utilization of the transmission system. The first is to use the standby time slot of the static multiplex section SDH network to configure "super-transmission services", and the second is to use the "iron-level" services of the Intelligent Automatic Switch Optical Network (ASON) SDH network (no protection, Preemptible), both methods use the protection resources of the network to issue additional services (service oversupply). When the network fails, the "oversend service" is automatically discarded, freeing up protection resources to meet the protection switching or recovery requirements of norm...
