Embodiment 1
[0168] The management system or controller performs service planning, plans service flow-level slices, and uses end-to-end slice IDs to distinguish them.
[0169] In this embodiment, based on the Eth service flow, the flow-level slice division of the OAN slice domain can be realized. Different OAN slices are distinguished by slice ID a, b, c, and the scope of the OAN slice starts from the input of the ONU device service flow to the OLT. The output of the uplink port on the device ends. Based on the OTN time slot granules, the time slot-level slice division of the OTN slice domain can be realized. Different time slot slices are distinguished by slice ID a1, b1, and c1. The egress of the transmission network.
[0170] In this embodiment, for the various business flows defined, according to the needs of management, such as Figure 22 As shown in (a), more detailed service flow isolation is realized in the OAN slice domain, and the OAN slice and the OTN slice form a 1:1 mapping ...
Embodiment 2
[0221] Embodiment 2 provides a specific implementation manner of implementing end-to-end slicing from an optical access network device to an optical transport network device.
[0222] On the management side, such as figure 2 As shown, the management system or controller has a network-wide service flow and slice view, can manage and configure information of OAN slice domains and OTN slice domains, and can establish slice mapping information from OAN slices to OTN slices.
[0223] For example, the management system or controller performs scenario planning for the OAN slice domain, and divides OAN slices for home PC, telephone, TV, and wireless base station access services to achieve service isolation. The management system or controller plans the scene of the OTN slice domain, and establishes the OTN slice according to the network upstream wired service provider and wireless service provider.
[0224] The management system or controller configures the management plane: configu...
Embodiment 3
[0228] Embodiment 3 provides a method for realizing splicing configuration from an OAN slice domain to an OTN slice domain.
[0229] In the third embodiment, the interface meaning of the two UNIs of the EVC is extended: the UNI interface corresponding to the OAN slice domain is an ETH service flow attribute identifier, and can be distinguished by an identifier similar to the service flow ID. The UNI interface corresponding to the transmission slice domain is an OTN time slot identifier, and these OTN time slots can be distinguished through the OTN time slot ID. The OTN time slot can be regarded as a miniaturized UNI interface. Specifically, ODU k，j , FlexE particle logo.
[0230] The advantage of using MEF EVC as a service flow description is that EVC can be bound to a service template. Through the EVC profile, the specific transmission characteristics of the service flow can be defined, such as QOS parameters such as CIR, PIR, CBS, and EBS, and the bandwidth, protection lev...
