在一些实施例中，在上述申请实施例的基础上，网络切片按照应用场景进行部署。In some embodiments, on the basis of the foregoing application embodiments, network slices are deployed according to application scenarios.
在本申请实施例中，应用场景可以包括增强型移动宽带eMBB、大规模机器通信mMTC和高可靠、低时延的通信uRLLC等。参见图2，集中单元DU和分布单元CU可以合一部署，如图1所示，核心网云化网元可以部署在数据中心，例如，Natioal数据DC、Regional DC等。对于具有低时延的业务，UPF可以部署在边缘数据中心，以提高通信响应速度，降低对核心数据中心的访问量。对于集中单元DU和分布单元CU分离部署的场景，增强型移动带宽eMBB和大规模机器通信mMTC的网络切片对于的CU-C和CU-U采用云化方式部署在Local DC。而低时延的通信uRLLC，则将CU-C部署在Local DC,而CU-U可以和DU采用PNF合一部署，如图3所示。In the embodiments of the present application, application scenarios may include enhanced mobile broadband eMBB, large-scale machine communication mMTC, and highly reliable, low-latency communication uRLLC, and the like. Referring to Figure 2, the centralized unit DU and the distribution unit CU can be deployed in one. As shown in Figure 1, the core network cloud-based network elements can be deployed in the data center, for example, National Data DC, Regional DC, etc. For services with low latency, UPF can be deployed in edge data centers to improve communication response speed and reduce access to core data centers. For the scenario where the centralized unit DU and the distributed unit CU are deployed separately, the network slices of enhanced mobile bandwidth eMBB and large-scale machine communication mMTC are deployed in the Local DC in a cloud-based manner for CU-C and CU-U. For low-latency communication uRLLC, CU-C is deployed in the Local DC, while CU-U and DU can be deployed in one PNF, as shown in Figure 3.

在本申请实施例中，网络切片可以依靠网域的网络设备实现，网络切片与网络设备之间可以存在映射关系，实现对网络设备资源的利用，其中，映射的方式可以包括物理端口映射、VLAN映射、DSCP映射、VxLAN映射至少一种。图4是本申请实施例提供的一种端到端网络切片映射的示例图，参见图4，网络切片可以与承载网络使用VLAN进行映射，在网络切片内部可以再采用DSCP和IP/POPT进行业务流的服务质量控制。参见图5，当网络切片对应的组网方式为集中单元CU/分布单元DU合一按PNF部署，集中单元CU/分布单元DU的每个网络切片可以对应一个VLAN，在同一个二层接入环，不同的分布单元DU/集中单元CU之间的VLAN ID不能重复。如果接入环是三层组网，则不同的分布单元DU/集中单元CU之间的VLAN ID可以重复。分布单元DU/集中单元CU是直接接入承载网络的接入设备，中间不通过其它的交换机或路由，即承载网可以直接看到分布单元DU/集中单元CU归属的VLAN ID。不同的VLAN ID，承载的PE设备接收到后，映射到不同的VPN隧道。承载内部根据隔离程度的要求，决定VPN是否建立在硬切片(如FlexE)或vNET之上。在一些实施例中，对于网络切片特有的NF，例如，UPF，也可以采用VLAN进行隔离，UPF业务的VLAN ID需要在协议栈ROSNG上配置，如vlan31,vlan41。NFVI平台，如TECS，在创建外部网络平面时，自动分配VLAN ID，如vlan 101，vlan202。这个网络平面对应MANO编排的外部网络平面。UPF在发送报文的时候，NFVI平台采用QinQ的方式传递VLAN ID，即在业务的VLAN的外层再嵌套平台的VLAN。NFVI分配的VLAN ID和业务协议栈的VLAN ID在CE将被剥离，在CE需要配置新的VLANID与其对应，如vlan 102,vlan 202，根据新分配的VLAN ID映射到承载的VPN。In this embodiment of the present application, network slicing may be implemented by relying on network devices in the network domain, and there may be a mapping relationship between network slicing and network devices, so as to utilize network device resources, wherein the mapping methods may include physical port mapping, VLAN At least one of mapping, DSCP mapping, and VxLAN mapping. FIG. 4 is an example diagram of an end-to-end network slice mapping provided by an embodiment of the present application. Referring to FIG. 4 , a network slice can be mapped with a bearer network using VLAN, and DSCP and IP/POPT can be used for services inside the network slice Streaming quality of service control. Referring to Figure 5, when the networking mode corresponding to the network slice is the centralized unit CU/distribution unit DU combined and deployed according to PNF, each network slice of the centralized unit CU/distribution unit DU can correspond to a VLAN, and access at the same layer 2 Ring, VLAN IDs between different distribution units DU/centralized units CU cannot be repeated. If the access ring is a Layer 3 network, the VLAN IDs between different distribution units DU/centralization units CU can be repeated. The distribution unit DU/centralized unit CU is an access device that directly accesses the bearer network without passing through other switches or routes, that is, the bearer network can directly see the VLAN ID to which the distribution unit DU/centralized unit CU belongs. Different VLAN IDs are mapped to different VPN tunnels after the bearer PE device receives them. According to the requirements of isolation degree, the bearer decides whether the VPN is built on hard slice (such as FlexE) or vNET. In some embodiments, the NF specific to the network slice, for example, UPF, can also be isolated by VLAN, and the VLAN ID of the UPF service needs to be configured on the protocol stack ROSNG, such as vlan31, vlan41. NFVI platforms, such as TECS, automatically assign VLAN IDs, such as vlan 101, vlan202, when creating an external network plane. This network plane corresponds to the external network plane orchestrated by MANO. When UPF sends packets, the NFVI platform uses QinQ to transmit the VLAN ID, that is, the platform VLAN is nested outside the service VLAN. The VLAN ID allocated by NFVI and the VLAN ID of the service protocol stack will be stripped on the CE, and a new VLAN ID needs to be configured on the CE to correspond to it, such as vlan 102 and vlan 202, which are mapped to the bearer VPN according to the newly allocated VLAN ID.
