Description
Technical Field
The present application relates to the field of computer technologies, and in particular, to a hybrid network configuration method and apparatus, a network structure, and an electronic device.
Background
In the existing Cloud service business, some users need Virtual Machines (VMs) based on a classic network, some users need VMs of a Private network (VPC) with higher security, and in order to meet the needs of different customers, a Cloud service provider often deploys a plurality of operation and maintenance units Zone in the same Machine room, some units are deployed as the classic network, and some units are deployed as the Private network. The classic network is a virtual machine network produced based on a traditional network architecture, defaults to the same large two-layer network, and carries out network security isolation through network isolation technologies such as security groups and the like; the so-called proprietary network is a customized network based on vxlan (virtual eXtensible Local Area network), a user can customize a network architecture of the user, isolation is performed on a big layer and a second layer based on encapsulated data packets, each proprietary network has a communication tunnel id of the proprietary network, and the data packets of the other proprietary network cannot be analyzed between different proprietary networks.
A conventional deployment structure is shown in fig. 1, where routing information of a classical network is configured on a physical switch, and a private network has a large number of conflicts in network addresses because a network segment can be customized, so that a network route is configured on a virtual gateway (XGW in the figure), a Zone corresponding to each classical network can define routing information corresponding to the network itself, and data sent from a virtual machine needs to be encapsulated and then sent to the virtual gateway, and then the virtual gateway unpacks the data and sends the data to a core network. The core network in the figure is the public network.
The prior art has the following defects:
1. when a service cluster is newly deployed, due to the fact that selection of a user is difficult to expect, at least 2 zones are often deployed as in fig. 1, and if a large amount of private networks are purchased by the user at the time and few classical networks are purchased by the user, a large-area shortage of goods of Zone B cannot regenerate virtual machines passing through a supporting typical network, and a large number of hosts (Node controllers, NCs) remain in Zone a, so that the situation that NC replenishment is needed although a large number of NCs actually remain in one service cluster is likely to occur.
2. The replenishment level is not well controlled, assuming that the machines of Zone a and Zone B in fig. 1 are both 500 machines, assuming that the set level of 80% (when selling 80% of all NCs in the same network type) requires replenishment, and in the worst case, if Zone a is sold up to 80% already occupying 400 NCs, Zone B has not yet sold 1 NC, which means that replenishment is still required in the case of the remaining 600 NCs. The above is that in the case of not considering the fragmentation of the resource, the situation is worse if the fragmentation is considered. If the water level is set too high, say 95%, it is likely that short purchase spikes will result in breakdown of the inventory.
3. The newly built service cluster generally cannot deploy too many machines, because the deployment unit uses a Zone as a unit, one Zone is assumed to deploy 1 rack, one rack can deploy 10 machines, if only 6 machines are to be deployed at the moment, 3 machines are used for building a classical network, and 3 machines are used for building a proprietary network, then 2 racks need to be occupied, and other positions of the two racks are left empty, so that resource waste is caused, and the cost is increased.
4. Under the condition that a proprietary network is good in selling, in the prior art, because the service cluster computing resources of the classical network are still reserved on the NC, the IP resources of the classical network can only be free and cannot be cut into service clusters of other classical networks for selling.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The invention changes the prior art that a network type, such as a network type virtual machine of a classical network or a proprietary network, is established on a host machine, thereby reducing the resource utilization rate of the host machine.
Fig. 2 is a schematic diagram of a network deployment structure of a service cluster according to an embodiment of the present invention. In the network deployment, a deployment unit Zone X of a hybrid network environment is configured, and virtual switches supporting two network types are simultaneously configured on each host NC in the Zone X, wherein a CP in the figure is a virtual switch of a classical network for communicating with a network port of a core network; the VP in the figure is a virtual switch of the private network for communicating with a network port of the core network, and since the private network allows a user to define the routing information corresponding to the private network, the network routing is configured in the virtual gateway XGW. The data of the virtual machine in the private network needs to be sent to the virtual gateway XGW for unpacking of the data packet before being sent to the core network.
In addition, if only a virtual switch of one network type is configured and/or initialized on each host on a deployment unit capable of supporting a hybrid network environment, or no network device of another network type is configured in the network, such as no physical switch and/or gateway device connected thereto, the deployment unit can only be regarded as a deployment unit of a single network.
For example, in fig. 2, although ports of virtual switches of two network types, namely, a classical network and a proprietary network, are configured on each host in the deployment unit Zone a, a virtual switch for the proprietary network in the network is not configured with a virtual gateway connected thereto, so the deployment unit Zone a can only be regarded as supporting only a classical network deployment unit. Similarly, although the ports of the virtual switches of the two network types, namely the classical network and the proprietary network, are configured on the hosts in the deployment unit Zone B, the virtual switch for the classical network in the network does not configure a physical switch connected thereto, so that the deployment unit Zone B can only be regarded as a deployment unit supporting only the proprietary network.
It should be noted that, in the conventional network deployment structure, data exchange and forwarding are performed between the created virtual network and the core network through a physical gateway, that is, in all the drawings, the physical gateway actually needs to be set between the typical network and the core network, and in view of this conventional setting, in order to simplify the contents of the drawings, the structure of the physical gateway is not explicitly drawn in all the drawings of the present disclosure.
Based on the schematic diagram of the network deployment structure of the service cluster shown in fig. 2, an embodiment of the present invention provides a system structure diagram of hybrid network configuration, which is used to perform network configuration on a virtual machine created on a host machine, so that the virtual machine is accessed to a network of a specified type, such as a classical network or a proprietary network, and then is connected to a public network through a gateway device of the specified network. As shown in fig. 3, the system structure of the hybrid network configuration includes: an open application programming interface (OpenAPI)310, a control server 320, and a controller (PYNC)330 provided on each host NC, wherein:
the control server 320, as a man-machine interaction interface between the user and the controller 330, is configured to receive a request for creating a virtual machine, which is input by the user, and specifies a network type of an access network of the virtual machine to be created. In order to obscure the difference of the two network types, the scheme replaces the two network types with a first network type and a second network type, wherein the first network type can be a classic network or a proprietary network, and the second network type is another network different from the first network type.
The control server 320 is configured to, after receiving a creation request for creating a virtual machine of a first network type or a second network type by a user, select a host supporting creation of the first network type or the second network type from a service cluster, and issue a creation instruction to the host, where the creation instruction is carried with all basic data for creating the virtual machine, and the basic data may be obtained by selecting the control server 320 from a preset basic database according to the creation request. The technical database stores basic data for creating the virtual machine in advance.
For example, the control server 320 may select a host from any one of the deployment units Zone X1 or Zone X2 supporting the network type selected by the user, and determine to issue a creation instruction for creating a virtual machine to the controller 330 on the host to instruct the controller 330 to create a virtual machine on the current host if the weak inventory has not reached the replenishment level after deducting the resources specified by the user on the host.
The controller 330 is configured to, after receiving a creation instruction for creating a virtual machine of a first network type or a second network type on a current host, control a virtual switch of the first network type on the host to create a first network port for connecting a virtual machine to be created according to basic data for creating the virtual machine carried in the creation instruction; or,
controlling a virtual switch of a second network type on a host machine to create a second network port for connecting a virtual machine to be created;
the controller 330 then creates a virtual machine on the host based on the underlying data.
Specifically, in the process of creating a plurality of virtual machines on the same host, the controller 330 may control a virtual switch of a first network type on the host to create a first network port for connecting the virtual machine to be created, where the virtual switch of the first network type is communicated with a gateway device of a first network and is communicated with a public network through the gateway device; controlling a virtual switch of a second network type on a host machine to create a second network port for connecting a virtual machine to be created, wherein the virtual switch of the second network type is communicated with gateway equipment of a second network and is communicated with a public network through the gateway equipment;
creating a virtual machine used for being communicated to a first network on a host machine, wherein the port configuration of a virtual network card of the virtual machine points to the first network port; and creating a virtual machine used for communicating to a second network on the host machine, wherein the port configuration of the virtual network card of the virtual machine points to the second network port.
It should be noted that the port configuration of the virtual network card of each virtual machine can only point to one network port on the virtual switch of the corresponding network type.
When the virtual machine is created, a libvirt program can be called, and the basic data in the creating instruction is used for creating virtual machine instance information, wherein the port configuration of the virtual network card in the instance information points to a corresponding first network port or a second network port.
In addition, before the virtual switch on the control host machine creates the first network port or the second network port for connecting the virtual machine to be created, it is further determined whether the virtual switch is available, that is, whether the virtual switch has completed initialization, and the virtual switch is communicated with the gateway device in the corresponding first network or the second network.
The specific process may be that whether the virtual switch completes initialization is judged first;
if the initialization is finished, triggering and controlling the virtual switch to create a first network port or a second network port for connecting a virtual machine to be created;
if the initialization is not completed, initializing the virtual switch to enable the virtual switch to be communicated with the gateway equipment of the network type to which the virtual switch belongs so as to be communicated with the public through the gateway equipment, and then triggering and controlling the virtual switch to create a first network port or a second network port for connecting a virtual machine to be created;
the initial state of the virtual switch is an uninitialized state.
The first network type may be a classical network, and the gateway device of the first network may be a physical gateway; the second network type may be a proprietary network and the gateway device of the second network may be a virtual gateway.
Finally, after the created virtual machine is started, the controller 330 may further detect the network smoothness of the virtual machine, so as to ensure that the user can use the virtual machine normally to receive and transmit data.
In the system structure diagram configured by the hybrid network provided by the embodiment of the invention, two network types of virtual switches are simultaneously arranged on each host, and the network types of the virtual machines to be created are configured and the virtual machines are created according to the instruction for creating the virtual machines, which is input by a user, through a controller on the host, so that the virtual machines of different network types can be supported in the creation on the same host, the resource utilization rate of the machine is improved, the spare capacity is reduced, and the equipment cost is reduced.
The technical solution of the present application is further illustrated by the following examples.
Example one
Based on the above concept of configuring and creating virtual machines of two network types on the same host, as shown in fig. 4, which is a flowchart of a hybrid network configuration method shown in the embodiment of the present invention, an execution subject of the method may be a controller on each host shown in fig. 3. As shown in fig. 4, the hybrid network configuration method includes the following steps:
s410, in the process of creating a plurality of virtual machines on the same host machine, controlling a virtual switch of a first network type on the host machine to create a first network port for connecting the virtual machines to be created, wherein the virtual switch of the first network type is communicated with gateway equipment of a first network and is communicated with a public network through the gateway equipment; and the virtual switch of the second network type on the control host machine establishes a second network port for connecting the virtual machine to be established, and the virtual switch of the second network type is communicated with the gateway equipment of the second network and is communicated with the public network through the gateway equipment.
For example, a classic network type virtual switch and a proprietary network type virtual switch are preset on a host, and when a plurality of virtual machines are required to be created on the same host and configured to be connected to a classic network or a proprietary network, a network port for connecting the virtual machine to be created can be created by controlling the classic network type virtual switch on the host, wherein the classic network type virtual switch is communicated with a physical gateway of the classic network and is communicated with a public network through the physical gateway.
Meanwhile, according to the creation requirement of the created virtual machine, the creation of a network port for connecting the virtual machine to be created can be controlled by a special network type virtual switch on the host machine, and the special network type virtual switch is communicated with a virtual gateway of the special network and is communicated with a public network through the virtual gateway.
The creating of the network port on the virtual switch means that a memory area is set on the virtual switch, the memory area corresponds to a unique port number and is used for receiving and forwarding data sent by the virtual machine, and a source of the data received through the network port uniquely points to a Media Access Control (MAC) address of the virtual machine connected to the network port.
S420, a virtual machine used for being communicated to a first network is established on a host machine, and the port configuration of a virtual network card of the virtual machine points to a first network port; and creating a virtual machine used for communicating to the second network on the host machine, wherein the port configuration of the virtual network card of the virtual machine points to the second network port.
For example, a virtual machine for communicating to the classic network is created on a host machine, and the port configuration of the virtual network card of the virtual machine points to one network port for connecting the virtual machine on the virtual switch of the classic network; and creating a virtual machine used for being communicated to the proprietary network on the host machine, wherein the port configuration of the virtual network card of the virtual machine points to one network port used for being connected with the virtual machine on the virtual switch of the proprietary network.
The configuration of the port of the virtual network card of the virtual machine is directed to a network port on the virtual switch, which means that the data sending address of the virtual network card is directed to the port number of the corresponding port on the virtual switch.
In the hybrid network configuration method provided by the embodiment of the invention, two network types of virtual switches are simultaneously arranged on each host machine, and in the process of creating a plurality of virtual machines on the same host machine, a virtual switch of a first network type on the host machine can be controlled to create a first network port for connecting the virtual machines to be created; the virtual switch for controlling the second network type on the host machine creates a second network port for connecting the virtual machine to be created, then creates a virtual machine for connecting the corresponding network type, and enables the port configuration of the virtual network card of the virtual machine to point to the corresponding first network port or second network port, thereby enabling the virtual machines supporting different network types to be created on the same host machine, improving the resource utilization rate of the machine, reducing the spare capacity and reducing the equipment cost.
Example two
As shown in fig. 5, a flow chart of a hybrid network configuration method according to a second embodiment of the present invention is shown, and the method can be regarded as a refinement of the method steps in the previous embodiment, as shown in fig. 5, the hybrid network configuration method includes the following steps:
s510, the control server receives a creating request of a user for creating a virtual machine of a first network type or a second network type, and selects a host machine supporting creation of the first network type or the second network type from the service cluster.
For example, the control server shown in fig. 3 may select a host from any one of the deployment units Zone X1 or Zone X2 supporting the user-selected classical network type or proprietary network type, and determine to issue a creation instruction for creating a virtual machine to the controller on the host if the inventory amount has not yet reached the replenishment level after deducting the resources specified by the user on the host, so as to instruct the controller to create a virtual machine of the corresponding network type on the current host. After the control server selects the host machine, the relevant information of the host machine is recorded so as to mark the used computing resources of the host machine.
S520, the control server sends a creating instruction to the host machine, the creating instruction carries basic data used for creating the virtual machine, and the basic data is obtained by the control server through selection from a basic database according to a creating request.
The control server inquires basic data of the virtual machine to be created from a basic database according to a creation request of a user, wherein the basic data comprises: and information such as dns, wsus, ntp, yum, control _ ip and the like of the virtual machine of the network type to be created is carried in the creation instruction and is issued to the control server on the selected host.
The subsequent steps are performed by the controller on the host machine.
S530, judging whether the virtual switch completes initialization;
after receiving the creation instruction, the controller on the host machine identifies the network type of the virtual machine to be created according to the basic data content, and then judges whether the virtual switch of the corresponding network type on the current host machine is initialized.
If the virtual switch does not complete initialization, performing S540, and if the virtual switch has completed initialization, performing S550; the initial state of the virtual switch is an uninitialized state.
S540, initializing the virtual switch to enable the virtual switch to be communicated with the gateway equipment of the network type to which the virtual switch belongs so as to be communicated with public through the gateway equipment;
when a network type virtual machine is created on a host machine for the first time, a controller on the host machine completes initialization of a network type virtual switch to enable the network type virtual switch to be available, namely, the virtual switch is communicated with a gateway device of the network type to which the virtual switch belongs so as to be communicated with public through the gateway device.
The initialization process is to connect the virtual switch to the physical network card on the host machine through the network bridge by program configuration, then connect to the physical switch in the corresponding network through the physical network card, and finally connect to the gateway device in the corresponding network, thereby opening the data transmission path from the virtual switch to the gateway device.
