Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The network configuration method provided by the present application can be applied to a traffic guidance system architecture as shown in fig. 1A. In fig. 1A, the traffic guidance system may include an orchestrator, a controller, and at least two network nodes, where the controller is in communication connection with the orchestrator and each of the network nodes, respectively, and at least one link is disposed between the network nodes, where the link type may include a network dedicated line, a network connection established based on internet, an MPLS (Multi-Protocol Label Switching) line, or a network connection established based on an SD-WAN (secure-wide WAN) accelerated network. Each network node can be deployed in different geographical areas respectively and can be used for providing services for local area networks of users with similar geographical positions.
The orchestrator can receive the network configuration information that the user submitted, and according to network configuration information generation arrangement strategy, issue to the controller. Specifically, a user can provide corresponding network configuration information according to actual networking requirements, the network configuration information can include line requirements such as site information to be communicated, bandwidth and the like, and other requirement information, after receiving the network configuration information, the orchestrator can select a proper network node according to the site information and generate an orchestration strategy corresponding to each network node according to other requirements.
The controller receives the arrangement strategy, generates a corresponding configuration instruction based on the arrangement strategy and sends the configuration instruction to the network node; and the network node receives and executes the configuration instruction to complete network configuration, and performs data forwarding on the traffic from the corresponding site based on the network configuration.
Referring to fig. 1B, fig. 1B further illustrates a network configuration generated by the network station after the network station executes the configuration instruction. The virtual switch can be created in a network node based on an Open VSwitch (OVS, virtual switch) technology, and the network configuration can be implemented based on the virtual switch.
The user terminal in fig. 1B may be a network outlet in the corresponding station, and may be a device where the user side interfaces with a network node. For example, the user terminal may be a switch of an enterprise or a server with Network Functions Virtualization (NFV).
The network node may be a device responsible for network configuration and data forwarding, and one or more virtual switches may be created in the network node, so that a plurality of different user terminals can multiplex the same network node. Different network nodes can be connected through a link, and based on the link, different communication tunnels (VXLAN) can be established according to actual requirements, so that a corresponding two-layer network is constructed. For example, in fig. 1B, network node 1 and network node 2 may be connected via link 1 and link 2, and then a VXLAN tunnel may be created on link 1 or link 2.
Referring to fig. 1B and fig. 2, a network configuration method provided in an embodiment of the present application may be applied to the controller, and the method may include the following steps.
S1: and receiving an arrangement strategy issued by an arranger, wherein the arrangement strategy comprises network configuration information of one or more users.
In this embodiment, different users may have different networking requirements. For example, in fig. 1B, network node 1 and network node 2 are distributed in two different cities (city a and city B). Assume that the orchestrator receives network configuration information for user a and user B: the user A needs to build a two-layer network from a branch mechanism (site) of the city A to a head office mechanism (opposite end site) of the city B, and the network bandwidth is 10M. Meanwhile, the user B needs to build a two-layer network from the data center a of the city a to the data center B of the city B, and the network bandwidth is 20M. The orchestrator may select, according to the geographical location of each network node, a network node 1 and a network node 2 from the site location information of the users a and B to construct a corresponding two-layer network, so that it may be determined that both the two-layer networks may be implemented through a communication tunnel between the network node 1 and the network node 2, respectively, for the network configuration information of the users a and B.
Specifically, in the scheduler, the corresponding network node may be determined according to the network configuration information of the user, and a corresponding scheduling policy may be generated. The scheduling policy may at least include a plurality of network nodes and respective access network cards of the plurality of network nodes, where communication tunnels are to be established, and a link selection mode of the communication tunnels to be established. According to the scenario shown in fig. 1B, the communication tunnel to be established may be a network node 1 and a network node 2, where the access network cards on the network node 1 may be a network card 1 and a network card 2, and the access network cards on the network node 2 may be a network card 3 and a network card 4. The link selection mode may be flexibly selected according to an actual application scenario, for example, the link selection mode may be a manual mode, and in the manual mode, the link between the network node 1 and the network node 2 may be divided into a main link and a standby link. Manual mode may then create a VXLAN tunnel based on the communication status of the primary and backup links. Also for example, the link selection mode may be an intelligent mode. The intelligent mode may evaluate each link between network node 1 and network node 2 to automatically screen out the links used to create the VXLAN tunnel.
In practical applications, when the intelligent mode evaluates each link, a parameter weight coefficient is usually required to be provided, and the parameter weight coefficient can be used as a weight value of various network quality parameters. For example, the link between the network node 1 and the network node 2 may have various network quality parameters such as a delay parameter, a jitter parameter, and a packet loss rate parameter, and respective weight values may be assigned to the network quality parameters. When the communication quality of each link is evaluated, the network quality parameters can be comprehensively evaluated in a weighted summation mode, so that the communication index of each link is obtained.
In one embodiment, the network configuration information may further include a platform VLAN id and a user VLAN id. Wherein the platform VLAN identification may be used to distinguish users of different platforms in the network node. The user VLAN identification can be in the same platform to distinguish different users. For example, user a and user B in fig. 1B may belong to different platforms, and network configuration information of the two users may include different platform VLAN identifiers. For another example, for user B, data transmission needs to be performed between data center a and data center B, and data center a and data center B may belong to different users, so that two different user VLAN identifiers may be included in the network configuration information of user B. Therefore, different platforms and different users can be isolated in the same network node through the platform VLAN identification and the user VLAN identification, and the data of different users can not interfere with each other while the network node is multiplexed.
In a specific application scenario, the network configuration information of the user a may be as follows:
the user name is as follows: a;
and (3) node docking: a network node 1 and a network card 1;
a network node 2 and a network card 3;
platform VLAN identification: 100, respectively;
user VLAN identification: none;
VXLAN tunnel: in the manual mode, the operation of the hand-operated device is carried out,
the main link: the number of the links 1 is such that,
and (3) preparing a link: link 2;
bandwidth: 10M
The network configuration information of user B may be as follows:
the user name is as follows: b;
and (3) node docking: a network node 1 and a network card 2;
a network node 2, a network card 4;
platform VLAN identification: 101, a first electrode and a second electrode;
user VLAN identification: the network node 1: 10
The network node 2: 20
VXLAN tunnel: in the intelligent mode, the user can select the mode,
parameter weight coefficient: a time delay weight alpha, a jitter weight beta and a packet loss rate weight gamma;
bandwidth: 20M
And correspondingly generating an arrangement strategy in the arranger according to the network configuration information of each user, wherein the arrangement strategy can be issued to the controller by calling the API of the controller through the arranger. After the controller receives the orchestration policy, the orchestration policy may be written to a database.
S3: and receiving node information reported by the network nodes, wherein the node information is used for representing the running state of the network nodes and/or the network quality among the network nodes.
In the present embodiment, in order to cope with fluctuations occurring in the network, each network node may periodically detect the network communication quality of the link, and may detect the operation state of itself. For example, the network node may detect parameters such as delay, jitter, packet loss rate, and the like of each link in a PING, TCPING, UDPING, and the like, and may detect the network card status of the network node itself. After the network node collects the node information, the node information can be reported to the controller. It should be noted that, since different network nodes may acquire parameters for the same link. For example, for the network node 1 and the network node 2, the delay, jitter, and packet loss rate of the link 1 and the link 2 are detected. After the controller receives the node information reported by the network node, the controller can adopt the parameters with later reporting time aiming at the parameters of the same link in the node information, thereby ensuring the real-time property of the link parameters as much as possible.
In practical application, after the network node acquires the node information, the node information can be sent to the controller through an OpenFlow protocol.
S5: and generating a configuration instruction set applied to the network node according to the arrangement strategy and the node information, and issuing the configuration instruction set to the network node so that the network node performs network configuration and data forwarding according to the configuration instruction set.
In this embodiment, the controller may generate corresponding configuration instruction sets for different network nodes according to the scheduling policy and the received node information. The set of configuration instructions may be for directing the network node to perform a network configuration. Specifically, the configuration instruction set may include multiple instructions such as adding a virtual network card, creating a bridge, adding a port, creating a flow table entry, creating a communication tunnel, and creating a QOS policy. In practical application, the above-mentioned multiple commands can be increased or decreased according to the complexity of the network.
Referring to fig. 1B, in an embodiment, the controller may generate an instruction to add a virtual network card and an instruction to add a flow entry by analyzing network configuration information of a user in the scheduling policy. Specifically, taking the user a as an example, the virtual network card br _ a may be created in the network node 1, and a data flow direction between the access network card 1 of the network node 1 and the created virtual network card br _ a may be created by adding a flow table entry. In this way, the data flowing in from the network card 1 can flow out from the virtual network card br _ a, and the data flowing in from the virtual network card br _ a can correspondingly flow out from the network card 1.
In order to complete the data flow between the access network card and the virtual network card, the controller may further generate an instruction to create a network bridge. The instructions to create a bridge may create a bridge in a network node for interfacing to a platform. For example, in fig. 1B, a bridge ovs-hub may be generated. The controller may also generate an instruction to add a port that may add an access network card and a virtual network card to the network bridge. For example, network card 1 and virtual network card br _ a may be added to the bridge ovs-hub.
In this embodiment, the controller may further generate an instruction to create a communication tunnel, and the instruction to create the communication tunnel may create a communication tunnel conforming to the link selection mode on the virtual network card. The manner in which the communication tunnel is created may also vary depending on the link selection mode. Specifically, if the link selection mode is the manual mode, it indicates that one link needs to be selected from the primary link and the backup link to create the VXLAN tunnel. In this case, the controller may identify the respective communication states of the primary link and the backup link from the node information reported by the network node. The communication state can be represented by parameters such as time delay, jitter, packet loss rate and the like. If the communication state meets a certain condition, for example, the packet loss rate is less than 50%, the communication state may represent that the communication is normal. When the link is selected, it is possible to preferentially determine whether the communication state of the main link is normal. If the communication state of the main link is normal, a VXLAN tunnel can be created directly on the main link, thereby generating an instruction to create a VXLAN tunnel on the main link. And if the communication state of the main link is abnormal and the communication state of the standby link is normal, an instruction for creating a VXLAN tunnel on the standby link can be generated.
In addition, if the link selection mode is the intelligent mode, it means that one link can be selected from a plurality of preset links to create the VXLAN tunnel. The preset links are not in a master-slave relationship with each other, so that the communication state of a certain link is usually not considered preferentially, the communication indexes of all the links are calculated according to the node information, and the target link is determined according to all the communication indexes. In practical application, each link may correspond to network quality parameters such as time delay, jitter, packet loss rate, and the like, and the network quality parameters are comprehensively evaluated in the weighted summation manner, so as to obtain communication indexes of each link.
After the communication indexes of the links are obtained, the link with the optimal communication index can be used as a target link. A VXLAN tunnel may then be created on the target link, thereby generating an instruction to create a VXLAN tunnel on the target link.
In one embodiment, the controller may further generate an instruction to create a QOS (Quality Of Service) policy according to the bandwidth information in the network configuration information. In particular, the instructions may create a QOS policy on the access network card that conforms to the bandwidth information. For example, for user a in fig. 1B, a QOS policy with a maximum rate of 10Mbps may be created on network card 1. And for user B, a QOS policy with a maximum rate of 20Mbps may be created on network card 2.
In one embodiment, in the same platform, data of different users may be distinguished by user VLAN identifiers, and when the network node performs network configuration in such a scenario, configuration instruction sets with different functions may also be generated. Specifically, for the user B in fig. 1B, the generated instruction to add a virtual network card may be used to create a virtual network card group including the first virtual network card br _ B and the second virtual network card br _ B1 in the network node 1. In practical applications, the virtual network card group may be a pair of veth network cards. The instructions may also create a third virtual network card br _ b.10 in the network node 1 corresponding to the user VLAN identification. It should be noted that, in the network configuration information of the user B, the user VLAN id for the network node 1 is 10, and the user VLAN id for the network node 2 is 20, then a virtual network card br _ b.10 corresponding to the id 10 may be created in the network node 1, and a virtual network card br _ b.20 corresponding to the id 20 may be created in the network node 2.
In this embodiment, when generating the instruction to create a bridge, the ovs-hub bridge is a docking platform, and in the same platform, in order to distinguish different users, in addition to creating the first bridge ovs-hub in the network node 1, a second bridge ovs-B may be added in the network node 1, where the second bridge corresponds to the user VLAN id 10. Thus, when the add port command is generated, the access network card 2 and the first virtual network card br _ B may be added to the first bridge ovs-hub, and the second virtual network card br _ B1 and the third virtual network card br _ b.10 may be added to the second bridge ovs-B.
In this embodiment, when the instruction for creating the flow entry is generated, a data flow direction between the access network card 2 and the first virtual network card br _ b may be established, and a data flow direction between the second virtual network card br _ b1 and the third virtual network card br _ b.10 may be established. Since the first virtual network card br _ b and the second virtual network card br _ b1 are a pair of virtual network card sets, the two virtual network cards can directly have data flow direction without re-establishment. Thus, the data flowing from the network card 2 may pass through br _ b and br _ b1 in sequence, and finally flow out from br _ b.10. Similarly, the data flowing from br _ b.10 may pass through br _ b1 and br _ b in sequence, and finally flow out from the network card 2.
In this embodiment, in order to distinguish data of different users, a corresponding user VLAN id may be added to the data. For example, the data flowing into the second virtual network card br _ b1 may carry the user VLAN id 10, but the data transmitted on the VXLAN tunnel is usually not allowed to carry the VLAN id, so the data may flow out from the third virtual network card br _ b.10 after the user VLAN id 10 is removed. Similarly, the data flowing into the third virtual network card br _ b.10 originally does not carry the user VLAN identifier 10, and in order to correctly forward the data to the corresponding user terminal, the data may flow out from the second virtual network card br _ b1 after being added with the user VLAN identifier 10. In the same way in the network node 2, the data flowing into br _ b.20 needs to add the user VLAN id 20 before it can flow out from br _ b1, while the data flowing into br _ b1 needs to remove the user VLAN id 20 before it can flow out from br _ b.20.
In the present embodiment, the instruction for creating a communication tunnel generated in the network node 1 for the user B may create a communication tunnel conforming to the link selection mode on the third virtual network card br _ b.10. For a specific way of creating the communication tunnel, reference may be made to the foregoing description, and details are not repeated here.
As can be seen from the above, in the embodiment of the present application, VLAN isolation is implemented by using a platform VLAN identifier and a user VLAN identifier, so that it is ensured that data of different users do not interfere with each other while multiplexing network nodes. In addition, inside the network node, the isolation of the two-layer network can be realized through multiple layers of ovs bridges, and the independence of data is further ensured.
Referring to fig. 3, an embodiment of the present application further provides a network configuration controller, where the network configuration controller includes:
the device comprises an arrangement strategy receiving unit, a scheduling unit and a scheduling unit, wherein the arrangement strategy receiving unit is used for receiving an arrangement strategy issued by an orchestrator, and the arrangement strategy comprises network configuration information of one or more users;
the node information receiving unit is used for receiving node information reported by the network nodes, and the node information is used for representing the running state of the network nodes and/or the network quality among the network nodes;
and the configuration instruction set issuing unit is used for generating a configuration instruction set applied to the network node according to the arrangement strategy and the node information, and issuing the configuration instruction set to the network node so that the network node performs network configuration and data forwarding according to the configuration instruction set.
Referring to fig. 4, an embodiment of the present application further provides a controller, where the controller includes a memory and a processor, the memory is used to store a computer program, and the computer program is executed by the processor to implement the network configuration method described above.
As can be seen from the above, according to the technical solution provided by the present application, the orchestrator may uniformly generate an orchestration policy without deploying the network configuration information of the user in each network node, where the orchestration policy may include the network configuration information of each user. Then, the orchestrator may issue the orchestration policy to the controller, and in addition, the controller may also receive node information reported by each network node. The node information may characterize the operational status of the network nodes, and may also characterize the network quality between the network nodes. Therefore, the controller can issue corresponding configuration instruction sets aiming at different network nodes by combining the scheduling strategy and the node information. The network node can perform network configuration and data forwarding according to the received configuration instruction set. Therefore, the controller can dynamically adjust the network configuration according to the real-time node information, so that the created two-layer network can cope with the fluctuating network environment. In addition, the orchestration of the network configuration information is performed uniformly by using the orchestrator, thereby simplifying the creation process of the two-layer network.
