Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application are described below with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present application, but not all embodiments. As can be known to those skilled in the art, with the advent of new application scenarios, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.

The naming or numbering of the steps appearing in the present application does not mean that the steps in the method flow have to be executed in the chronological/logical order indicated by the naming or numbering, and the named or numbered process steps may be executed in a modified order depending on the technical purpose to be achieved, as long as the same or similar technical effects are achieved. The division of the units presented in this application is a logical division, and in practical applications, there may be another division, for example, multiple units may be combined or integrated into another system, or some features may be omitted, or not executed, and in addition, the shown or discussed coupling or direct coupling or communication connection between each other may be through some interfaces, and the indirect coupling or communication connection between the units may be in an electrical or other similar form, which is not limited in this application. Furthermore, the units or sub-units described as the separate parts may or may not be physically separate, may or may not be physical units, or may be distributed in a plurality of circuit units, and some or all of the units may be selected according to actual needs to achieve the purpose of the present disclosure.
At present, some customers often prefer to rent a subnet in an optical transmission network of an operator to realize their operation on the subnet in order to conveniently and efficiently perform service distribution and service operation at any time. For example, in a case where some companies have branch companies at multiple places, it is often inclined to rent a sub-network to an operator, so as to conveniently open and operate and maintain an optical transmission network between the branch companies at the multiple places through the sub-network.
However, after tenants lease subnetworks in an operator, there is no effective method for isolating an optical transmission network according to tenants at present, and the subnetworks leased by multiple tenants are prone to interfere with each other. For example, after an a tenant rents an a subnet in an optical transmission network, when the a tenant needs to open an optical transmission network service from a point a to a point b, an optical transmission network path from the point a to the point b, which is opened by an operator, may include network devices other than the a subnet, that is, the optical transmission network service that the a tenant opens may occupy network devices in subnets corresponding to other tenants. That is, the network device resources between the subnets may occupy each other, causing mutual interference between the subnets.
The optical transmission network refers to a network that transmits optical signals between a transmitting side and a receiving side, such as an optical fiber transmission network; a sub-network, which may also be referred to as a sub-network, refers to a part of the entire optical transmission network of the operator, and may also be considered as a part of network devices in the entire optical transmission network of the operator; service distribution refers to opening an optical transmission network service, for example, opening an optical transmission network service between point to point; the service operation and maintenance refers to operations performed to maintain network devices and services in order to ensure that the services operate normally.
In view of this, an embodiment of the present application provides a service processing method, where a service request sent by a user is obtained through an SDN controller, a subnet (i.e., a network device set) corresponding to the user is determined according to an identifier in the service request, and then the network device set is controlled to process the service request, so that a processing range of the service request is limited within a subnet range corresponding to the user, and mutual interference between subnets is avoided.
Referring to fig. 1, fig. 1 is a schematic view of an application scenario of a service processing method according to an embodiment of the present application. As shown in fig. 1, the application scenario specifically includes a server, one or more terminal devices, and a plurality of network devices; the method includes the steps that an SDN controller is deployed on a server and used for controlling a plurality of network devices connected with the server, a user can send a service request to the SDN controller on the server through one or more terminal devices, after the SDN controller obtains the service request, a network device set rented by the user is determined in the network devices according to an identifier in the service request, and therefore the determined network device set is controlled to process the service request, such as service issuing or service operation and maintenance.
The terminal device includes, but is not limited to, a tablet computer, a notebook computer, a palm computer, a personal computer, a smart phone, and the like. The network device may be a device for implementing network transmission in a transmission network, and the network device may be, for example, an optical transmission device including, but not limited to, an optical fiber transceiver, an optical switch, or an optical modem.
Referring to fig. 2, fig. 2 is a schematic flowchart of a service processing method 200 according to an embodiment of the present application; as shown in fig. 2, a service processing method 200 provided in the embodiment of the present application includes:
201. the SDN controller obtains a request 1, wherein the request 1 carries an identifier 1.
The SDN controller is an application program in the SDN, can be deployed on a server, and can be used as an operating system in a network to realize control over the network. The SDN controller may provide a northbound interface (NBI) to a user to enable the user to access the SDN controller and perform service processing through the SDN controller, for example, perform operations such as service release or service operation and maintenance. It is to be understood that NBI is an interface defined for a user to access and manage a network, and that the user may use NBI to define and develop network management applications (e.g., SDN controllers) in the application layer so that the user may access and manage the network through these applications.
That is, the user may send a request 1 to the SDN controller by invoking the NBI provided by the SDN controller to request the SDN controller for service processing. The request 1 may be a service processing request, such as a service issuing request or a service operation and maintenance request, where the request 1 may carry an identifier 1, and the identifier 1 is used to determine a network device set corresponding to the user, that is, a network device set rented by the user. The identifier 1 may be an identifier returned to the user by the SDN controller after the SDN controller divides the network device set corresponding to the user in the network; the identifier 1 may also be an identifier returned to the user by the SDN controller after confirming the identity information of the user. The embodiment of the present application does not specifically limit the identifier 1.
202. The SDN controller determines a set of network devices from identity 1.
The network device set and the identifier 1 have a corresponding relationship, and the network device set includes one or more network devices. For example, when a user requests to an operator to rent a subnet, the operator may determine the subnet divided to the user according to the requirement of the user (e.g., transmission capacity, transmission bandwidth, or transmission delay of the subnet, etc.), and then the operator may divide the corresponding subnet for the user on an SDN controller, that is, associate the user with a set of network devices in the subnet rented by the user on the SDN controller. Correspondingly, after establishing the association relationship between the user and the network device set, the SDN controller may generate an identifier 1, where the identifier 1 is used to determine the network device set, that is, the identifier 1 may be considered as an Identity Document (ID) corresponding to the network device set.
The network devices in the network device set may be devices for implementing network transmission in a transmission network, and the network devices may be, for example, optical transmission devices, including but not limited to optical communication devices such as optical fiber transceivers, optical switches, or optical modems; the network devices in the network device set may also be a pluggable circuit board (i.e., a single board) on the communication device, a communication interface (i.e., a port) on the single board for connecting an optical fiber, or a device with a finer granularity such as a different communication channel (i.e., a channel) logically subdivided in each port.
203. The SDN controller controls the set of network devices to process request 1.
After determining the network device set corresponding to the request 1, the SDN controller may control the network device set to process the service request by issuing an instruction to one or more network devices in the network device set, so as to limit a processing range of the service request within a subnet range corresponding to a user.
For example, the SDN controller may generate a service processing instruction according to the request 1, where the service processing instruction may carry specific configuration information, and the SDN controller may issue the service processing instruction to one or more network devices in the network device set, so that after receiving the service processing instruction, the one or more network devices may apply the configuration information to execute a relevant service operation, thereby implementing control of the network devices by the SDN controller.
In this embodiment, a service request sent by a user is obtained by the SDN controller, a network device set corresponding to the user is determined according to an identifier in the service request, and then the network device set is controlled to process the service request, so that a processing range of the service request is limited within a network device set range corresponding to the user, and mutual interference between network device sets rented by different users is avoided. In addition, in this embodiment, by implementing isolation between different network device sets on the SDN controller, that is, implementing isolation between network device sets in a software layer, technology intrusion into a network device is not required, that is, in this embodiment, technology upgrade is not required to be performed on a network device, and the SDN controller can be compatible with an old network device.
Referring to fig. 3, fig. 3 is another schematic flow chart of a service processing method 200 according to an embodiment of the present application; as shown in fig. 3, in a specific embodiment, the step 203 further includes:
2031. the SDN controller determines a service issuing path according to the request 1 and the network device set, wherein the request 1 is a service issuing request.
In the case that the request 1 is a service issuance request, for example, a user requests to open an optical transport network service, the SDN controller needs to control, according to the request 1, a network device in a network device set corresponding to the user to open the optical transport network service.
Before the optical transmission network service is opened, the SDN controller may calculate a service delivery path, so as to facilitate subsequent delivery of the service according to the service delivery path. For example, when a user requests to open an optical transport network service from a point a to a point B, the SDN controller may calculate a transmission path for the optical transport service from the point a to the point B, where the transmission path may be, for example, from a network device a at the point a to a network device C at the point C, and then be transmitted to a network device B at the point B by the network device C at the point C; after the transmission path is obtained through calculation, the SDN controller may control the network device a, the network device b, and the network device c on the transmission path to perform service delivery, that is, to perform provisioning of an optical transmission service.
Specifically, in this embodiment, in order to limit the processing range of the service issuance request to the range of the network device set corresponding to the user, the SDN controller may determine the service issuance path according to the network device set corresponding to the user and the request 1, so as to ensure that the network devices on the service issuance path are all devices in the network device set corresponding to the user. That is to say, the SDN controller may determine, according to network devices included in the network device set, one or more network devices used for performing service provisioning in the network device set, determine a service provisioning path, and ensure that the network devices on the service provisioning path are all devices in the network device set corresponding to the user.
2032. The SDN controller controls the network device 1 to issue a service according to the service issuance path, where the network device 1 is a device located on the service issuance path, and the network device 1 is a device in the network device set.
After the SDN controller determines the service delivery path, the network device 1 may be controlled to deliver the service according to the service delivery path. The network device 1 may be one or more network devices on the service distribution path, and the network device 1 may be, for example, the network device a, the network device b, and the network device c in step 2031.
Exemplarily, in the case that the network device 1 is a network device a, a network device b, and a network device c, the SDN controller may generate a service issuance instruction according to the request 1, where the service issuance instruction may carry configuration information related to service issuance, and the SDN controller may issue the service issuance instruction to the network device a, the network device b, and the network device c, so that after receiving the service issuance instruction, the network device a, the network device b, and the network device c may apply the configuration information to execute a service issuance operation, thereby implementing that the SDN controller controls the network device to issue the service.
Referring to fig. 4, fig. 4 is a schematic flowchart of a service processing method 400 according to an embodiment of the present application; as shown in fig. 4, the service processing method 400 includes:
401. the terminal device sends a request 2 to the SDN controller, wherein the request 2 carries login information and is used for requesting login.
The tenant system can be deployed on the terminal device, and a user can complete the operation on the network device set by operating the tenant system on the terminal device. Before a user uses a tenant system, the user may perform a login operation on the tenant system so that the SDN controller can confirm identity information of the user.
Specifically, a user may perform a login operation on a tenant system of a terminal device, for example, account information, password information, and the like of the user may be input, after receiving the login operation of the user, the terminal device sends a request 2 to an SDN controller, where the request 2 may carry login information, such as the account information and the password information, input by the user, and is used to request the SDN controller to log in.
402. The SDN controller performs an authentication operation on request 2.
Specifically, the SDN controller may verify whether the user has the right to log in to the tenant system according to the login information carried in the request 2, in other words, the SDN controller determines whether the user rents a network device set in the network according to the login information. When the user rents a network equipment set in the network, the login authentication of the user is successful, namely, the user can pass the login authentication. Moreover, the SDN controller may determine identity information of the user according to the login information of the user, and further determine a network device set corresponding to the user according to the identity information of the user. For example, after an operator divides a corresponding network device set for a user through an SDM controller, a corresponding relationship between the identity information of the user and the network device set may be established, for example, the identity information of the user may be a unique user ID, and the network device set corresponding to the user also has a unique network device set ID, that is, the user ID and the network device set ID have a unique corresponding relationship; therefore, the SDN controller may determine a corresponding user ID according to login information of the user, and then determine a corresponding network device set ID according to the user ID.
403. And the SDN controller generates an identifier 2 according to the login information of the user.
After the SDN controller determines the identity information of the user according to the login information of the user, the user may generate the identifier 2 according to the identity information of the user. The identifier 2 corresponds to identity information of a user, and the identifier 2 may be, for example, a user ID and has a corresponding relationship with a network device set ID; the identity 2 may also be a token (token), for example, for marking the identity information of the user.
404. The SDN controller sends an identity 2 to the terminal device.
405. And the terminal equipment sends a request 3 to the SDN controller, wherein the request 3 carries the identifier 2.
After the terminal device receives the identifier 2 returned by the SDN controller, the terminal device may carry the identifier 2 in the request 3 when sending the request 3 to the SDN controller, so as to prove the legal identity of the terminal device. The request 3 may be a service processing request, such as a service issuing request or a service operation and maintenance request.
406. The SDN controller determines the set of network devices from the identification 2 in the request 3.
After receiving the request 3 sent by the terminal device, the SDN controller may determine identity information of the user according to the identifier 2 in the request 3, and then determine a corresponding network device set according to the identity information of the user.
407. And the SDN controller sends a service processing instruction to the network equipment set.
After the SDN controller determines the corresponding network device set, the SDN controller may generate a service processing instruction according to the request 3, where the service processing instruction may carry specific configuration information, so as to enable the network device set to perform a service processing operation.
The SDN controller may determine, from request 3, one or more network devices of the set of network devices to process request 3, and then send traffic processing instructions to the determined one or more network devices of the set of network devices. For example, in a case that the request 3 is a service issuance request, the SDN controller determines a service issuance path in the network device set according to a preset algorithm, where one or more network devices located on the service issuance path are network devices for processing the request 3, and the SDN controller may send a service issuance instruction to the one or more network devices located on the service issuance path.
408. And the network equipment set executes the service processing operation according to the service processing instruction.
After the network device set obtains the service processing instruction issued by the SDN controller, the network device set may execute a relevant service operation, such as service issuance or service operation and maintenance, by applying the configuration information, so as to implement control of the SDN controller on the network device set.
409. And the SDN controller returns a service processing result to the terminal equipment.
