Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
When data forwarding is currently performed, a Bridge Virtual Interface on a Virtual Bridge is in a BVI (Bridge Group Virtual Interface) Interface mode, that is, a BVI Interface is used to implement a data forwarding function between different ports. However, the native routing interface, which is a set of bridge interfaces represented by one interface, has drawbacks and irrationality: that is, data in the same network segment is forwarded by one BVI interface, and when secondary forwarding is required, the same interface is defaulted, because the interface defaults that two gateways are in the same network segment, a router set in the same network can only pass through the same gateway, and network collision is easily caused. Therefore, the embodiment of the application discloses an interface setting method, device, equipment and medium, which can improve the data forwarding performance and avoid network conflict.
Referring to fig. 2, an embodiment of the present application discloses an interface setting method, including:
step S11: and determining the data forwarding mode of the current network and determining the number of virtual machines of the current subnet.
In this embodiment, first, a data forwarding manner of a current network is determined, and the number of virtual machines of a current subnet is determined. It should be noted that the data forwarding manner may include two-layer forwarding and three-layer forwarding.
Step S12: and generating a corresponding number of target sockets based on the data forwarding mode and the number of the virtual machines.
In this embodiment, a corresponding number of target sockets are generated according to the data forwarding manner and the number of virtual machines, that is, data of the target sockets are determined according to the data forwarding manner and the number of virtual machines.
Step S13: and loading the target socket to the corresponding virtual bridge and the virtual router so as to facilitate the data communication of the virtual machines of the sub-networks.
In this embodiment, after the target socket is generated, the target socket is loaded into the corresponding virtual bridge and the virtual router, so that the virtual machines of the subnets perform data communication, that is, the communication of the virtual machines is completed. The socket may be used for a virtual Host node user interface, and may provide services for a DHCP (Dynamic Host Configuration Protocol) terminal. Because the target sockets with the number corresponding to the number of the virtual machines are generated, network conflict caused by data forwarding through only one interface in the prior art is avoided, and faster and more efficient data forwarding is realized.
Therefore, the data forwarding mode of the current network is determined, and the number of the virtual machines of the current subnet is determined; generating a corresponding number of target sockets based on the data forwarding mode and the number of the virtual machines; and loading the target socket to the corresponding virtual bridge and the virtual router so as to facilitate the data communication of the virtual machines of the sub-networks. Therefore, the data forwarding mode of the current network and the number of the virtual machines of the current subnet are determined, then the corresponding number of target sockets are generated according to the data forwarding mode of the current network card and the number of the virtual machines, and the generated target sockets are loaded to the virtual bridge and the virtual router respectively, so that data communication among the virtual machines in each subnet is realized. Therefore, by generating the target sockets with the number corresponding to that of the virtual machines, network conflicts caused by data forwarding through only one interface are avoided, and the performance and the efficiency of data forwarding are improved.
Referring to fig. 3, the embodiment of the present application discloses a specific interface setting method, and compared with the previous embodiment, the embodiment further describes and optimizes the technical solution. The method specifically comprises the following steps:
step S21: and if the data forwarding mode of the current network is determined to be two-layer forwarding, determining the number of the virtual machines of the current subnet.
In this embodiment, if the data forwarding manner of the current network is two-layer forwarding, the number of virtual machines of the current subnet is further determined.
Step S22: and generating a corresponding number of target sockets based on the data forwarding mode and the number of the virtual machines.
In this embodiment, a corresponding number of target sockets are generated by a data forwarding manner and the number of virtual machines. And for the two-layer forwarding, target sockets with the same number as the virtual machines are generated, and the target sockets correspond to the virtual machines one by one and can be distinguished through the set identification ID. It can be understood that when performing layer two forwarding, no route matching is needed, and therefore the interface does not need to configure MAC address and gateway IP, and the part of layer two forwarding can be completed only in the virtual bridge.
Step S23: loading the target socket to a corresponding virtual network bridge so that each virtual machine of the current sub-network can carry out data communication through the virtual network bridge; wherein the number of the target sockets is the same as the number of the virtual machines.
In this embodiment, since the two-layer forwarding does not need to perform route matching, and the data forwarding process can be completed through the virtual bridge, the target socket is only required to be loaded to the virtual bridge corresponding to the current subnet, so that each virtual machine of the current subnet performs data communication through the virtual bridge. It should be noted that the two-layer forwarding is applicable to two Virtual machines of the same network and the same host, and when the two Virtual machines communicate with each other, only the socket in the Virtual bridge is loaded to implement the two-layer forwarding, for example, in fig. 4, the data communication process between VM1 (Virtual Machine) and VM2 in the subnet 1 only needs to perform data communication through socket 0/1 and socket 0/2 of the bridge in fig. 4, and socket 0/1 corresponds to VM1 and socket 0/2 corresponds to VM 2.
It can be seen that, in the embodiment of the present application, if it is determined that the data forwarding manner of the current network is two-layer forwarding, the number of virtual machines in the current subnet is further determined, then target socket ports with the same number as the virtual machines are generated based on the two-layer forwarding manner of the data, and the target socket ports are loaded to the virtual bridge, so that each virtual machine in the current subnet realizes data communication. Because the generated target socket is corresponding to each virtual machine in the current subnet, different virtual machines adopt the corresponding sockets to forward data, network conflicts caused by that all virtual machines forward data only through the same interface are avoided, and meanwhile, the performance and the efficiency of data forwarding are improved.
Referring to fig. 5, the embodiment of the present application discloses a specific interface setting method, and compared with the previous embodiment, the embodiment further describes and optimizes the technical solution. The method specifically comprises the following steps:
step S31: and if the data forwarding mode of the current network is determined to be three-layer forwarding, determining the number of the virtual machines of the current subnet.
In this embodiment, if the data forwarding mode of the current network is three-layer forwarding, the number of virtual machines in the current subnet is further determined.
Step S32: and generating a corresponding number of target sockets based on the data forwarding mode and the number of the virtual machines.
In this embodiment, for three-layer forwarding, target sockets twice as many as the virtual machines are generated, and the target sockets and the virtual machines have a corresponding relationship and can also be distinguished by the set identifier ID. It can be understood that, when performing three-layer forwarding, the socket configures an MAC address and a gateway IP, and the opposite end connects with the socket of the virtual router to perform virtual routing forwarding, that is, three-layer forwarding, which relates to that the routing three-layer forwarding is completed in the virtual routing repeater.
Step S33: determining a plurality of set interface sets in the target socket; each socket group comprises a first set of interfaces and a second set of interfaces, and the number of the socket groups is the same as that of the virtual machines.
In this embodiment, it should be noted that there are several sets of interface groups in the target socket, each set of interface group includes a first set of interface and a second set of interface, and the number of the socket groups is the same as the number of the virtual machines. That is, if the forwarding is three-layer forwarding, a socket group corresponding to the virtual machine is generated.
Step S34: and loading the first set of interfaces in each socket group to a corresponding virtual bridge to serve as a server interface, and loading the second set of interfaces in each socket group to a corresponding virtual router to serve as a client interface, so that the virtual machines of the sub-networks perform data communication through the socket groups.
In this embodiment, a first set of interfaces in a socket group is loaded into a virtual bridge corresponding to a current subnet to serve as a server-side interface, a second set of interfaces in the socket group is loaded into a corresponding virtual router to serve as a client-side interface, when a user needs to point out, three-layer forwarding is applicable to two virtual machines of different networks and the same host, for a VLAN network, a VLAN tag needs to be changed on a virtual router of a network node, the three-layer forwarding passes through the virtual router, and a set of socket groups mapped to each other is loaded to match interfaces in a local-side bridge and the virtual router, thereby completing the three-layer forwarding. In this way, sockets can set multiple gateways for the same network segment, that is, one bridge can set multiple interfaces, and sockets appear in pairs. When a router is established to enable two virtual machines to communicate, the master-slave device mode sockets are complete, the network bridge at the virtual machine end serves as a service port and corresponds to a client port in a three-layer route forwarding process, a corresponding MAC address and a gateway IP are set, and forwarding can be carried out after a corresponding route forwarding action is inquired, so that the forwarding efficiency of the router is greatly improved. For data packets of types such as broadcast and unknown unicast, the data packets do not need to be flooded to all nodes so as to avoid the problems of overlarge load and the like, and the exclusive routing forwarding interface enables data forwarding to form a mesh shape so as not to cause network conflict.
In addition, the socket in this embodiment is a socket that can share the memory package, the shared memory package is set by using a file socket as a control channel, and thus the shared memory package can be used for communication, and the two ends of the socket are designed to be mapped to each other, in one-to-one correspondence, and serve as two roles similar to a server and a client, and the client is connected to the server through the existing socket. Each interface can be connected to a peer interface at the same time, distinguishable by a unique parameter identification ID and corresponding to the peer interface. For example, in fig. 4, data communication between VM1 or VM2 and VM3 is three-layer forwarding, and taking data communication between VM1 and VM3 as an example, socket 0/1 in the bridge corresponding to subnet 1, socket 0/1 in virtual router 1, socket 0/3 in virtual router 1 and socket 0/3 in the bridge corresponding to subnet 2 are needed to implement data communication between virtual machines VM1 and VM 3. Wherein, the socket 0/1 in the bridge corresponding to the subnet 1 and the socket 0/1 in the virtual router 1 are respectively used as a server interface and a client interface, and are in one-to-one correspondence, and similarly, the socket 0/3 in the bridge corresponding to the subnet 2 and the socket 0/3 in the virtual router 1 also have a correspondence.
Furthermore, for the same network and different hosts, the labels carried by the different hosts cannot be intercommunicated when the different hosts are communicated with each other, and the labels in the network packet can be converted through the socket of the application to match the two layers of intercommunication; when external network communication is connected, floating IP or fixed IP network communication is added, and the external network connection is still provided by the network bridge, so that communication of a plurality of network components is not needed, namely, only a group of mapping sockets provided by the application are needed to be connected with the internal network bridge, and the virtual router is connected with the external network for forwarding.
It can be seen that, in the embodiment of the present application, if it is determined that the data forwarding manner of the current network is three-tier forwarding, the number of virtual machines of the current subnet is further determined, then a complete set of socket groups is generated based on the three-tier forwarding manner of the data to serve as a client interface and a server interface, respectively, and the server interface is loaded to the virtual bridge and the client interface is loaded to the virtual router. The virtual router data plane forwarding function is realized by the socket in pair aiming at the network data forwarding interface, the receiving and sending processes of the network communication implementation mode to the data packet are optimized, the forwarding efficiency of the data forwarding plane to the data processing process is improved, the data packet processing process is improved so as to realize three-layer routing forwarding better, and the virtual router data plane forwarding function has different gateway functions when a plurality of routers are bound to the same network. By the method, network conflict can be avoided, the forwarding performance of the network data packet can be improved, the length of a network data link is shortened, and delay of the network is avoided. And particularly, when the network forwarding is carried out in a large flow and the throughput is high, the network data forwarding is faster and more efficient.
In the data processing process, different network ports of each network segment may load independent interfaces and set a fault tolerance mechanism, as shown in fig. 6 and 7, an embodiment of the present application discloses a network interface setting method suitable for interface change of a virtual machine, including:
step S41: and if the virtual machine interface in the current subnet changes, judging that the corresponding virtual router needs to execute interface adding operation or interface removing operation.
In this embodiment, if the virtual machine interface of the current subnet changes, it is determined that the corresponding virtual router needs to perform an interface adding operation or an interface removing operation, and then corresponding configuration is performed according to the action.
Step S42: and if interface adding operation needs to be executed, inquiring a subinterface corresponding to the current network, inserting the subinterface into a corresponding virtual network bridge, and setting the subinterface in an enabling state.
In this embodiment, if the operation is an interface addition operation, a subinterface corresponding to the current network is queried, the subinterface is inserted into the corresponding virtual network bridge, and the state of the network subinterface is set to be an enabled state; if the subinterface corresponding to the current network does not exist when the subinterface is inquired, the subinterface needs to be created first. When it is necessary to pay attention to, before inquiring the sub-interfaces, it is necessary to determine whether the network card that depends on exists and is normal, if there is no direct return error, if there is and the network card is normal in the enabled state, the sub-interface corresponding to the network is inquired.
In another specific embodiment, after the determining that the corresponding virtual router needs to perform the interface adding operation or the interface removing operation, the method further includes: if the interface removing operation needs to be executed, removing the corresponding socket from the virtual bridge and the virtual router, and judging whether other sockets exist in the virtual bridge and the virtual router; if not, removing the virtual bridge and the virtual router. That is, if the interface removal operation is performed, the corresponding socket is directly removed from the virtual bridge and the virtual router, and it is determined whether there is a socket providing another routing function in the virtual bridge and the virtual router, and if not, the virtual bridge and the virtual router are also removed together. Further, after determining whether there are other sockets in the virtual bridge and the virtual router, the method further includes: if other sockets exist in the virtual router, reserving the virtual router; and if other sockets exist in the virtual bridge, reserving the virtual bridge. That is, if the interface is an interface removing operation, it is also necessary to determine whether an interface corresponding to the current subnet interface exists, if not, an error is returned, if so, an interface in a two-layer bridge process and an interface in a three-layer route forwarding process are deleted, and then, it is determined whether a virtual router in which the interface in the three-layer virtual routing process is located has another interface providing a routing function, if not, the virtual router is deleted, and it is determined whether another interface exists in the two-layer bridge, if not, the bridge is directly removed, and if there is another interface, the bridge needs to be retained.
Step S43: and judging whether a socket corresponding to the current subnet exists, if not, creating a corresponding socket according to the data forwarding mode of the current network, and loading the socket to the corresponding virtual bridge and the subinterface of the virtual router.
In this embodiment, it needs to determine whether there is a socket corresponding to the current subnet, and if not, create a corresponding socket according to the data forwarding manner of the current network, and load the socket into the subinterfaces of the virtual bridge and the virtual router. For example, if the forwarding is three-layer forwarding, a server interface is created in the second-layer bridge, a client interface is created in the virtual router for three-layer forwarding, the issued MAC is set as the corresponding client interface, then the corresponding virtual router is inserted and the interface state is set to be enabled, if the virtual router does not exist, the gateway IP is set for the three-layer virtual router forwarding interface according to the issued configuration. It should be noted that if the Source Address Translation (SNAT) function is already turned on, the same Network in the fixed virtual router may only need to share one socket.
In addition, after the loading the socket to the corresponding virtual bridge and the virtual router, the method further includes: judging whether the current network is an external network or not; if the network is an external network, starting a source address translation function, and setting an interface NAT in the virtual router to be in an external state. It can be understood that the present embodiment needs to determine whether the current network is an external network or an internal network. If the virtual router is an external network, a source address conversion function needs to be started, an interface NAT in the virtual router is set to be in an external state, and a gateway IP is set to be a dynamic NAT address based on the current virtual router; if the network is an internal network, the interface gateway in the three-layer virtual route forwarding process is directly set to be in an internal state. It should be noted that, if the external network is used, it is necessary to determine whether to start the source address translation function, and if not, subsequent related configuration is not required.
It can be seen that if the virtual machine interface in the current subnet changes, the interface adding operation and the interface removing operation need to be executed according to the specific change. If the operation is the interface adding operation, firstly judging whether the network card is normal or not, further inquiring whether a sub-interface corresponding to the current network exists or not, if so, inserting the sub-interface into the virtual network bridge and setting the sub-interface to be in a starting state, then judging whether a socket interface corresponding to the current subnet exists or not, and if not, establishing a socket interface group and respectively loading the socket interface group to the virtual network bridge and the virtual router so as to finish the interface adding operation. If the interface removing operation is performed, firstly, corresponding sockets are directly removed from the virtual bridge and the virtual router, then whether other interfaces provide routing functions or not is determined, if not, the virtual bridge and the virtual router are also removed, and if the virtual bridge or the virtual router also has other sockets providing routing functions, the virtual bridge or the virtual router is reserved.
Referring to fig. 8, an embodiment of the present application discloses an interface setting apparatus, including:
an information determining module 11, configured to determine a data forwarding manner of a current network, and determine the number of virtual machines in a current subnet;
a socket generating module 12, configured to generate a corresponding number of target sockets based on the data forwarding manner and the number of virtual machines;
and a socket loading module 13, configured to load the target socket to a corresponding virtual bridge and a corresponding virtual router, so that the virtual machines of the subnets perform data communication.
Therefore, the data forwarding mode of the current network is determined, and the number of the virtual machines of the current subnet is determined; generating a corresponding number of target sockets based on the data forwarding mode and the number of the virtual machines; and loading the target socket to the corresponding virtual bridge and the virtual router so as to facilitate the data communication of the virtual machines of the sub-networks. Therefore, the data forwarding mode of the current network and the number of the virtual machines of the current subnet are determined, then the corresponding number of target sockets are generated according to the data forwarding mode of the current network card and the number of the virtual machines, and the generated target sockets are loaded to the virtual network bridge and the virtual router respectively, so that data communication among the virtual machines in each subnet is realized. Therefore, by generating the target sockets with the number corresponding to the number of the virtual machines, network conflict caused by data forwarding through only one interface is avoided, and the performance and the efficiency of data forwarding are improved.
