     DETAILED DESCRIPTION 
     To make the objects, technical schemes and advantages of the present disclosure clearer, in the following the present disclosure is described in more detail by specific embodiments with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate the present disclosure and are not intended to limit the present disclosure. 
     Exemplary Embodiment I 
     To solve the problem that a manual operation which is not convenient for unified management is required during configuring of virtual resources and opening relevant cloud services for users by a cloud management platform when an application request is received, a method for cloud service management is provided. The method for cloud service management will be described with reference to embodiments below. 
     Referring to  FIG. 1 ,  FIG. 1  is a basic flowchart of a method for cloud service management according to an embodiment of the present disclosure. The method for cloud service management includes steps S 101 -S 104 . At S 101 , when receiving a work order of an application request, a service management module splits the work order, creates a department and a virtual data center (VDC), and creates a user and binds the user to the department and the VDC. 
     In the embodiment, when receiving the work order of the application request, the service management module automatically creates a total thread which may be called “Work Order Service” thread. The embodiments of the present disclosure are not limited to this thread, a developer can develop a customized thread if needed. Then, the “Work Order Service” thread splits the work order. The work order includes a resource creation request and a resource parameter. The resource creation request includes at least one selected from a group consisting of: network creation request, route creation request, firewall creation request, virtual machine creation request, cloud disk creation request and load balance creation request. 
     In the embodiment, the work order of the application request received by the service management module is the work order of a first application request, and the work order of the first application request is an internal cloud service request. The internal cloud service request may be an application procedure for an internal employee to submit related resources and products in a conventional operation and maintenance OA system of an operator when he wants to subscribe to a service catalog or purchase resources and products, and this application is the work order of the first application request. 
     In the embodiment, when receiving the work order of the first application request, the service management module splits the work order, and then verifies the work order to check a presence of a tenant of the VDC of a cloud resource to be created by the work order. If the tenant exists, the “Work Order Service” thread calls an ORG (Organize) thread to create a department and a VDC; and then, the “Work Order Service” thread calls an ACL (Access Control List) thread to create a user, and binds the user to the department created by the ORG thread, and binds the user to the VDC created by the ORG thread. If the VDC tenant does not exist, a cloud environment with the number of eni networks and private networks meeting the application may be selected according to the quota quantities in a work order requested by a user, and then an address pool is verified. When the verification does not meet the preset application requirements, the “Work Order Service” thread performs a return processing and informs the user. When the verification meets the preset application requirements, the verification is successful, and the “Work Order Service” thread calls the ORG thread to create a department and a VDC; and then, the “Work Order Service” thread calls the ACL thread to create a user, binds the user to the department created by the ORG thread, and binds the user to the VDC created by the ORG thread. 
     In the embodiment, the work order further includes an access token, and before the ORG thread creates the department and the VDC, the service management module also checks a permission of a user according to the access token. In the embodiment, the “Work Order Service” thread of the service management module calls an IAM (Identity and Access Management) thread to check the permission of the user according to the access token. The permission of the user includes the resource permission that the user can call and the basic permission that the user can access. After checking the permission of the user, the permission of the user is obtained and returned to the “Work Order Service” thread. 
     In the embodiment, moreover, the work order of the application request received by the service management module may be a work order of a first application request and/or a work order of a second application request, and the work order of the second application request is an external cloud service request. The external cloud service may be a financial cloud service, an enterprise cloud service, etc. The external cloud service request may be an application process for an enterprise user to submit related resources and products in the IBP system of the traditional operation and maintenance system of the operator when he wants to open the external network cloud link function, and this application is the work order of the second application request. In addition to a resource request and a resource parameter, the work order also includes configuration information of a port, such as uplink port of ONU, uplink and downlink ports of OLT device, uplink and downlink ports of convergence switch, LSNID, LAN access type, OLT device name, OLT port number, VLAN and other information. In the embodiment, when receiving the work order of the second application request, the service management module splits the work order, creates a department and a VDC, and creates a user. Before binding the user to the department and the VDC, the service management module further sends splitting information for the second application request to a network operation resource center of an operator, and sends configuration information in the second application request to the resource management module. The resource management module performs a port configuration for an access side of the external cloud service according to the port configuration information, and configures a rule for converting qinq to vlan or for converting qinq to vxlan in a front-end switch. 
     In the embodiment, a DCI (Data Center Interconnection) thread in the resource management module automatically performs a port configuration for an access layer of the cloud service according to the configuration information of the uplink port of ONU, the uplink and the downlink port of OLT device, the uplink and the downlink port of convergence switch, and automatically configures a rule for converting qinq to vlan or for converting qinq to vxlan according to LSNID, LAN access type, OLT device name, OLT port number, VLAN and other information. The resource management module further calls an API interface of the SDN controller to configure an external network mapping relation between VIN and VLAN. 
     At S 102 , the resource management module sends the resource parameter to an underlying resource pool through an interface. 
     In the embodiment, the “Work Order Service” thread of the service management module calls an OPERATE thread of the resource management module for the resource creation request and the resource parameter of the work order. When the resource creation request is a virtual machine creation request, the virtual machine resource request is sent to a virtual resource management (VRM) thread of the resource management module. The VRM thread sends the resource parameter for creating a virtual machine to the underlying resource pool through the API interface, calls a resource, deploys a virtual machine resource function, and so on. The resource parameter for creating a virtual machine includes, but is not limited to, a virtual machine image and a virtual machine specification. 
     When the resource creation request is at least one of network creation request, route creation request, firewall creation request and load balance creation request, the OPERATE thread sends the resource creation request to the DCI thread to create a network, a route, a firewall and a load balance. The DCI thread sends the resource parameter to the underlying resource pool through the API interface, calls a resource, deploys a resource function, and so on. The resource creation parameters include at least one of the following: network CIDR, VLAN, cloud firewall and cloud load balance policy rules, but not limited to the above resource parameters. 
     When the resource creation request is a cloud disk creation request, the OPERATE thread sends the resource request to a VOLUME thread to create a cloud disk. The resource parameters for creating the cloud disk include at least one of the following: data disk size, system disk size and cloud disk type. The VOLUME thread sends the resource parameter to the underlying resource pool through the API interface, calls a resource, and deploys a resource function, and so on. 
     At S 103 , the resource management module sends a first notification to a software defined network (SDN) controller. 
     In the embodiment, the first notification is a notification requesting to send a flow table. 
     At S 104 , the SDN controller sends the flow table to gateway device according to the first notification. 
     In the embodiment, the SDN controller sends the flow table to the gateway device according to the notification of sending the flow table sent by the resource management module. The gateway device includes Bleaf gateway device and/or ILeaf gateway device, which realizes the connection and communication according to the requirements of the access layer equipment user and the creation of the cloud resource. 
     In the embodiment, when receiving the second request by the service management module, sending, by the SDN controller, the flow table to the gateway device according to the first notification further includes: calling, by the resource management module, the API interface of the SDN controller to configure the external network mapping relation between VIN and VLAN, and sending, by the SDN controller, all flow tables of VLAN/VXLAN mapping relation to the gateway device. The resource management module adds network VLAN information created by the DCI thread to the port according to the mapping relation, and adds the port to VNI under VDC created by ORG thread of the service management module. After successful configuration, the “Work Order Service” thread returns a response of successful configuration to IBP system, and the IBP system sends the work order to the customer service center of the data center for external deployment. 
     According to the method for cloud service management provided by the embodiments of the present disclosure, when receiving a work order of an application request, a service management module splits the work order, creates a department and a VDC, creates a user using an ACL thread, and binds the user to the department and the VDC, where the work order includes a resource creation request and a resource parameter; a resource management module sends the resource request parameter to an underlying resource pool through an API interface, and the underlying resource pool creates a resource according to the resource creation request parameter; and the resource management module sends a notification requesting to send a flow table to a SDN controller, and the SDN controller sends the flow table to gateway device. In this way, an automatic analysis of an application work order of a user is realized and an automatic creation of cloud resources is completed.

The port configuration for the access side includes configuration for the interfaced LSN (Local Service Node) stacked BLEAF switch and port group, and the name and port group of the front-end switch of the interfaced OLT. An interface of the SDN controller triggers a Spine-leaf border convergence switch in LSN, to configure the VLAN/VXLAN mapping relation of a BLEAF switch port, and interface with the multi service edge (MSE) router of LSN through VLAN encapsulation. MSE completes the mutual mapping between VLAN and VxLAN in LSN, and MSE is a direct access to MAN. 
     In the embodiment, the SDN controller is further configured to send a flow table of the configured external network mapping relation between VIN and VLAN to the gateway device according to the first notification. 
     The resource management module is further configured to add the created network VLAN information to the port according to the mapping relation, and add the port to the VNI in the VDC. 
     In the embodiment, the device for cloud service management is further configured for the management of the virtualization system, the management of the SDN module, and the unified management of the whole process. 
     In the embodiment, the virtual resource pool module integrates physical servers to form one or more logical virtual resource pools, sharing resources including but not limited to computing, storage and network, and providing an external interface to connect with the cloud management platform. 
     In the embodiment, the gateway device may include BLEAF gateway device and/or ILEAF gateway device. The gateway device supports the OpenFlow protocol. The gateway device is mainly a layer  3  switch working at the network layer, has a routing function, and provides a northbound interface to communicate with the SDN controller. 
     According to the device for cloud service management provided by the embodiments of the present disclosure, when receiving a work order of an application request for an internal cloud service and/or an external cloud service, a service management module splits and verifies the work order for the internal cloud service, checks a permission of a user, creates a department and a VDC, creates a user, and binds the user to the department and the VDC. A resource management module sends the resource parameter to the resource pool of the virtual resource pool module through an API interface, and the resource management module also sends a first notification to the SDN controller, where the first notification is a notification requesting to send a flow table. The resource pool of the virtual resource module provides an interface to the cloud management platform, which enables the cloud management platform to uniformly arrange, manage and monitor the resource of the resource pool. The SDN controller sends a flow table to gateway device according to the first notification. The work order for the external cloud service is split, and the configuration information in the work order is sent to the resource management module. The resource management module performs a port configuration for an access side of the external cloud service according to the configuration information, and configures a rule for converting qinq to vlan or for converting qinq to vxlan in a front-end switch, calls an API interface of the SDN controller to configure an external network mapping relation between VIN and VLAN, and then sends the resource parameter to an underlying resource pool through the API interface, calls a resource and deploys a resource function. The resource management module sends the first notification to the SDN controller, and the SDN controller may send a flow table of the configured external network mapping relation between VIN and VLAN to the gateway device according to the first notification. According to the device for cloud service management, a manual operation and configuration which is inconvenient for unified management is avoided during configuring virtual resources for users by the cloud management platform. A manual transmission of a configuration to a front-end switch of OLT is avoided, and an automatic configuration for the interfaced LSN stacked BLEAF switch and port group and the equipment name and port group of a front-end switch of OLT are achieved. An automatic configuration of a rule for converting qinq to vlan (vxlan) is completed. An automatic opening of users&#39; internal cloud services and external cloud services is achieved, to achieve integrated internal and external hybrid cloud services and reduce maintenance costs.
