The number of the management nodes 10 may be one or more. Multiple management and control nodes 10 may be deployed on the same physical machine or on different physical machines.

The edge cloud is a cloud computing platform constructed on an edge infrastructure based on the cloud computing technology and the edge computing capability, and is a cloud platform with the computing, network, storage, security and other capabilities at the edge position. The edge cloud is a relative concept, the edge cloud is a cloud computing platform relatively close to a terminal, or is different from a management node or a traditional cloud computing platform, the management node or the traditional cloud computing platform can comprise a data center or a machine room with large resource scale and concentrated positions, the edge cloud is composed of a plurality of edge cloud nodes, the resource scale of a single edge cloud node is smaller, but the number of the edge cloud nodes is larger, so that the coverage range of the edge cloud is wider. In other words, the network system S10 of the present embodiment is also a cloud computing platform constructed on the edge infrastructure based on the cloud computing technology and the edge computing capability, is a cloud computing platform with computing, network, storage, security and other capabilities at the edge location, is a cloud computing platform relatively close to the terminal, and is also a network system constructed based on the management and control node or the infrastructure between the traditional cloud computing system and the terminal.

In this embodiment, an edge node 20 may be a machine room, a Data Center (DC), or an internet Data Center (Internet Data Center, IDC), etc. For an edge cloud network, one edge node 20 may include one or more edge nodes. The plural means 2 or more than 2. Each edge cloud node may include a series of edge infrastructures including, but not limited to: distributed Data Center (DC), wireless room or cluster, operator's communication network, core network devices, base stations, edge gateways, home gateways, computing devices or storage devices, and corresponding network environments, etc. The location, capabilities, and inclusion of infrastructure of the different edge nodes may or may not be the same as described herein.

Wherein the hardware resources may include: computing resources such as processors, memory, disk, and the like. Wherein the processor may be CPU, GPU, FPGA, etc. The software resources may include: bandwidth, network segment, network card configuration, etc., and an operating system, etc.
In this embodiment, the infrastructure contained by different edge nodes 20 may be the same or different. The resources available to the physical machines in the same edge node 20 may be the same or different. As the edge nodes 20 are varied. The network configuration adapted by the edge nodes 20 of different resources is different, and based on this, how to perform network configuration for heterogeneous resources becomes a technical problem to be solved in the edge cloud technology.
In this embodiment, the edge node 20 may provide registration information to the management node 10 when joining an edge cloud system (network system provided in this embodiment), i.e., when being mounted on the management node 10. The edge node 20 newly joining the network system S10 is a newly added edge node in the network system S10. In the K8s environment, the newly added edge Node is mainly a work responsible Node (Node) of a new access K8s control Node (master) Node. Wherein the registration information includes: the attribute description information of the resource provided by the edge node 20, i.e. the resource information of the edge node 20.

In the embodiment of the present application, when the edge node 20 is newly mounted on the management node 10, network configuration is required for the newly added edge node 20 to provide services to the outside. For convenience of description, a newly added edge node in the network system S10 is defined as a first edge node, as shown in fig. 1, and denoted by reference numeral 201.
Further, for the first edge node 201, a network configuration request may be provided to the management node 10.
Accordingly, the management node 10 may receive the network configuration request, and obtain the resource information of the first edge node 201 from the pre-stored resource information according to the network configuration request. Specifically, the management node 10 may parse the node identification of the first edge node from the network configuration request. Node identification refers to information that uniquely identifies an edge node, such as may be a node ID, node number, etc.
Further, the management node 10 may obtain the resource information of the first edge node 201 from the pre-stored resource information according to the node identifier. Alternatively, the management and control node 10 may utilize the node identifier to match in the pre-stored correspondence between the node identifier and the resource information, and determine the resource information corresponding to the node identifier carried by the network configuration request, as the resource information of the first edge node 201.

The network mode supported by the physical machine may be, but not limited to, an ipvlan mode, a macvlan mode, a bridge mode, an overlay mode, an unresolve mode, or a VPC mode. For example, the physical machines of kernel 3.10 can only support bridge mode, the physical machines of kernels 4.9 and 4.19 can support macvlan and ipvlan, the physical machines of programmable switches, VPC mode, etc.
Alternatively, for a plurality of pieces of operating system information and a plurality of pieces of supported network environment information, a relevant weight may be set for each information item, and a network mode supported by the physical machine and the like may be determined according to the operating information supported by the physical machine, the supported network environment information, and the weight of each information item.
Optionally, the management node 10 may further determine, according to the network mode supported by the physical machine, a network execution tool corresponding to the network mode supported by the physical machine, as a network execution tool adapted by the first edge node 201. Wherein the network execution tool is an iptables tool or an ebpf tool.
Optionally, the management node 10 may further obtain, from the resource information of the first edge node, the network resource information of the first edge node as the network resource adapted by the first edge node. For example, the policing node 10 may select an unassigned IP address from the network segment of the first edge node as the IP address of the physical machine of the first edge node 201. For another example, the management node 10 may use the routing information of the first edge node as the routing information of the physical machine, and so on.
The above description will exemplify the embodiment of determining the network configuration information adapted to the first edge node by taking the network mode, the network execution tool, and the network resource information adapted to the first edge node as examples only, but does not mean that the network information is configured only for the first edge node, or that all the network information is configured for the first edge node.
After determining the network configuration information, the management node 10 may provide the network configuration information to the first edge node 201. Accordingly, the first edge node 201 may perform network configuration according to the network configuration information. Because the network configuration information determined by the management and control node is the network configuration information adapted to the resources of the edge node, the network configuration information adapted to the resources of the edge node can be determined for the edge node with heterogeneous resources, and heterogeneous resource network configuration is realized.
The network system provided by the embodiment of the application can carry out network configuration for the edge node running example besides carrying out network configuration for the edge node with heterogeneous resources.

Accordingly, the management and control node 10 may select, from the physical machines in the target edge node, a physical machine whose service quality parameter value meets the service quality requirement of the cloud computing service as the target physical machine. For a specific implementation of the cloud computing service deployment of the target edge node on the target physical machine, reference may be made to the relevant content of the foregoing embodiment, which is not described herein.
For the target physical machine deployed with the above example, the management node 10 may be requested to perform network configuration for the example in the example deployment process.
Correspondingly, the management and control node 10 can acquire the network configuration information of the edge node according to the identification of the edge node to which the target physical machine belongs; determining the network configuration information of an instance according to the network configuration information of the edge node and a pre-configured instance isolation strategy; and issuing the network configuration information of the instance to the target physical machine. In the embodiment of the present application, for convenience of description and distinction, an edge node to which a target physical machine belongs is defined as a second edge node.

In the embodiment of the present application, the specific implementation manner of the management and control node 10 to obtain the preconfigured instance isolation policy is not limited. In some embodiments, the preconfigured network quarantine policy may be a network quarantine policy provided by a service demander or a network quarantine policy preconfigured for a cloud service provider. In some embodiments, the management node 10 may provide a human-machine interaction interface, such as a network policy interface, through which a user may autonomously configure instance isolation policies. Accordingly, the management and control node 10 provides a network configuration entry in response to a call operation for the network policy interface; and in response to the interoperation for the network configuration portal, obtaining an instance network isolation policy provided by the interoperation; and stores the instance network isolation policies provided by the interoperation. Optionally, the management node 10 may store a correspondence between the user identification and the instance network isolation policy.
Accordingly, when determining the network configuration information of the instance, the management and control node 10 may obtain the user identifier from the service deployment information, and further, may match the correspondence between the preset user identifier and the instance network isolation policy, so as to obtain the instance network isolation policy corresponding to the user identifier carried by the service deployment information, as the preset instance isolation policy.

Optionally, the target physical machine may acquire a network execution tool supported by the instance from the network configuration information of the instance; and calling a target network execution tool to carry out network configuration on the instance according to the network configuration information of the instance, thereby realizing the instance network configuration under heterogeneous resources.
In the embodiment of the present application, the management node 10 may provide a network policy interface in addition to the automatic instance network configuration, and the service demander performs network configuration. Accordingly, the management and control node 10 may provide a network configuration portal in response to a call operation for the network policy interface; responding to the interactive operation aiming at the network configuration inlet, and acquiring example network configuration information provided by the interactive operation; and providing the instance network configuration information to the target physical machine. Optionally, the management and control node 10 may obtain a user identifier that provides the instance network configuration information, and determine, according to the user identifier, a physical machine where an instance corresponding to the user identifier is located as a target physical machine; further, the management node 10 may provide instance network configuration information to the target physical machine.
Optionally, because the network information autonomously configured by the user does not necessarily meet the requirements, the management node 10 may also verify the instance network configuration information before providing it to the target physical machine. Specifically, the management and control node 10 may obtain a configuration syntax of the instance network configuration information; judging whether the configuration grammar accords with the set grammar specification or not; and/or judging whether the instance network configuration information belongs to the network resource with the use permission of the user.
For an alternative embodiment, the management node 10 may determine that the instance network configuration information passes the verification and provide the instance network configuration information to the target physical machine if the determination result of the alternative determination operation is yes. For the embodiment in which the above two judging operations are combined, the management and control node 10 may determine that the instance network configuration information passes the verification and provide the instance network configuration information to the target physical machine if the judging results of the two judging operations are both yes.
Accordingly, the target physical machine can perform network configuration on the instance according to the network configuration information of the instance. The specific implementation manner of the network configuration of the target physical machine to the instance may refer to the relevant content of the foregoing embodiment, which is not repeated herein.

For the K8s node, a network agent (agent) component may be deployed on the K8s node and configured through the network agent component. In this implementation, the management node 10 comprises: master node.

The network component may be run for the first edge node 201 to deploy the application network component in the first edge node. The application network component is a software functional module, such as an application program, for realizing the corresponding function. Further, the first edge node 201 may invoke an application network component to provide a network configuration request to the management node 10. In some embodiments, the application network component may include: a network proxy component.
