Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to the field of network port configuration technologies, and in particular, to port-bound data forwarding for an aggregation group.
Background
At present, with the improvement of development technology and the difference of market demands, the requirement on the virtual machine is higher and higher, and more products need to run value-added services and other services in the virtual machine. If the network bandwidth is required, the network bandwidth can be expanded by binding the ports. Generally, the implementation of the bound port needs to depend on the binding of an external switch, that is, not only the port of the virtual machine itself needs to be bound, but also an aggregation group needs to be added to the switch for an external physical network cable, so that the complete implementation of the bound port can be completed.
For the implementation of the bound port, if only the physical network card is used, the problems of service interruption and the like generally do not occur. But special problems may occur if binding ports is implemented by virtual machines. The most important of these problems is the potential interruption of the physical network card traffic. Virtual network cards are used in virtual machines, for example for kvm-type virtual machines, typically bound in order to create macvtap. The Macvtap needs to bind a physical network card and a network card actually existing in a host. And the Macvtap performs data interactive forwarding by depending on the corresponding host machine physical network card. When the port is bound, a plurality of macvtaps are bound, and the physical network card associated with the macvtap is not bound any more. This may cause that the port can only operate through the virtual network card after joining the aggregation group, and the service of the physical network card itself may be abnormal.
Therefore, in order to solve the above problem in the prior art, that is, after the virtual network card is bound, the corresponding port is added to the aggregation group, which results in the problem that the IP on the physical network card cannot be ping-through forwarded, an optimized implementation method for port-bound data forwarding of the aggregation group needs to be provided, so as to implement coexistence configuration of the physical network card and the virtual network card, thereby solving the problem of service interruption on the physical network card after the virtual network card is bound.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two non-identical entities with the same name or different parameters, and it is understood that "first" and "second" are only used for convenience of expression and should not be construed as limiting the embodiments of the present invention. Furthermore, the terms "comprises" and "comprising," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements does not include all of the other steps or elements inherent in the list.
The invention provides a method for solving the problem of service interruption of a physical network card after a virtual network card is bound.
Generally, in order to implement a bound port in a network, aggregation group processing in a switch is required. And after the port is added into the aggregation group, judging and forwarding according to the mode of the bound port. For example, after the ports 1, 2, and 3 are bound, the bound ports are usually in a polling mode, that is, each packet is sequentially forwarded at three ports in sequence, thereby achieving the purpose of increasing the bandwidth. If both ends of the data forwarding link connection are configured accurately, then there is generally no problem. However, if the data is continuously sent to the network card corresponding to port 1 on port 1 according to the forwarding sequence only after the switch is configured to join the aggregation group, the data may be sent to the network card corresponding to port 2 due to the polling forwarding policy. At this time, the network card at port 1 will lose packets, and then service interruption occurs. Therefore, the problem of service interruption can not occur only when the same type of network card is bound and successfully set.
However, with the improvement of development technology and different market demands, the requirement on the virtual machine is higher and higher, and more products need to run value-added services and the like in the virtual machine. Therefore, the establishment and participation of virtual machines is increasingly required. Therefore, when the virtual network card and the physical network card are shared, that is, when the virtual network card performs port binding, the network port corresponding to the associated physical network card must be added to the aggregation group in the switch. At this time, the aggregation group in the switch fixes the forwarding table as the bound Mac address of the virtual network card, because the forwarding judgment is performed according to the bound port mode. In this case, the physical network card will no longer be used, but is filtered because the Mac address of the virtual network card has already been bound. At this time, data interaction cannot be performed due to forwarding limitation of the switch in the data service on the physical network card associated with the virtual network card, so that problems such as service interruption occur.
To address this problem, it is proposed according to the present invention to distinguish the types of virtual network cards and physical network cards by means of Mac addresses. The Mac address is a unique identifier of the network device. The Mac addresses of different vendors are not identical and can be distinguished from each other. Typically, the Mac address for the virtual network card is also fixed and differentiated. For example, the virtual network card Mac address of a kvm-type virtual machine starts at 52:54:00, the virtual network card Mac address of a vmware-type virtual machine starts at 00:0C:29, and so on. Therefore, when the port is added into the aggregation group, whether the forwarding table of the aggregation group is the Mac address of the virtual machine can be judged according to the port, and then the analysis is carried out according to the Mac address in the actual data packet. If the Mac address of the physical network card exists, filtering is not performed according to the filtering rule of the previous binding convention, and the Mac address is forwarded as a common port. Therefore, the purpose of coexistence and use of the binding port of the virtual network card and the physical network card can be achieved, and the problem that the virtual network card and the physical network card cannot coexist after being bound so that the service of the physical network card is interrupted is solved. In addition, aiming at different scenes, the function can be used as a configuration option, and the virtual network card and the physical network card can be used together more flexibly.
To this end, in a first aspect of the invention, a method 100 for port bonding for an aggregation group is provided. Fig. 1 shows a schematic block diagram of an embodiment of a method for aggregating port bindings for a group according to the present invention. In the embodiment shown in fig. 1, the method comprises:
step S110: identifying the configuration conditions of a virtual network card and a physical network card in a network;
step S120: in response to the coexistence configuration of a virtual network card and a physical network card, determining a characteristic Mac address bit of the virtual network card and storing a corresponding port forwarding table for standby; step S130: adding the port into an aggregation group, judging the address type in a forwarding table of the aggregation group based on the characteristic Mac address bit, and analyzing the Mac corresponding to each data packet
The address and its type;
step S140: responding to the address type as a virtual network card, and performing data forwarding based on preset forwarding logic according to the Mac address;
step S150: and in response to the address type being a physical network card, determining a forwarding port based on a stored port forwarding table according to the Mac address to perform data forwarding.
In summary, to solve the above problems in the prior art, it is first required to determine whether there is a need for coexistence of a virtual network card and a physical network card in the current network environment. Therefore, in step S110, the configuration of the virtual network card and the physical network card in the network is identified. In other words, it is first determined whether a coexistence configuration exists between the virtual network card and the physical network card. Subsequently, when it is determined that there is a requirement that the virtual network card and the physical network card coexist in the current network environment, that is, it is determined that there is a coexistence configuration of the virtual network card and the physical network card, in step S120, the types of the virtual network card and the physical network card are distinguished by means of the Mac address according to the concept of the present invention. Specifically, the characteristic Mac address bit of the virtual network card is determined, and the corresponding port forwarding table is saved for standby before the port joins the aggregation group.
On this basis, in step S130, the port is added to the aggregation group, and it is determined whether the address type in the forwarding table of the aggregation group belongs to the virtual network card or the physical network card based on the characteristic Mac address bit determined in step S120. And resolves the Mac address and its type for each packet.
If the address type is determined to be the virtual network card, data forwarding is performed based on a preset forwarding logic according to the Mac address in step S140. Namely, data forwarding through the virtual network card and the switch of the virtual machine is normally performed.
If the address type is determined not to be a virtual network card but a physical network card, a forwarding port is determined based on the saved port forwarding table according to the Mac address in step S150 to perform data forwarding. That is, if the Mac address in the data packet is a physical network card, the Mac address is not a virtual network card, and the Mac address is compared with the stored forwarding table data, so as to determine which forwarding port to forward. If the data in the forwarding table does not exist, the forwarding table is used as a common port for matching forwarding.
In some embodiments of the method 100 for aggregating port bindings for a group according to the present invention, the method further comprises:
step S160: and responding to the coexistence configuration that the virtual network card and the physical network card do not exist, adding the ports into the aggregation group and executing data forwarding according to the bound port mode.
Aiming at different scenes, the coexistence function can be used as a configuration option, and the virtual network card and the physical network card can be used in a coexistence manner more flexibly. Therefore, when it is determined that the requirement of coexistence of the virtual network card and the physical network card does not exist in the current network environment, that is, it is determined that coexistence configuration of the virtual network card and the physical network card does not exist, in step S160, the ports are added into the aggregation group and data forwarding is performed according to the bound port mode, that is, operation is performed according to the aggregation group-based data forwarding mode in the prior art. The requirement that coexistence does not exist includes a case where only the physical network card is used, and also includes a case where the virtual network card and the physical network card are used but the physical network card is not needed to execute the service.
In some embodiments of the method 100 for port binding of an aggregation group according to the present invention, the step S120, in response to the existence of the coexistence configuration of the virtual network card and the physical network card, determining the Mac address bit of the characteristic of the virtual network card and saving the corresponding port forwarding table for standby further includes: and determining different characteristic Mac address bits according to the virtual network cards of different types of virtual machines.
Specifically, the Mac address is a unique identification of the network device. The Mac addresses of different vendors are not identical and can be distinguished from each other. Typically, the Mac address for the virtual network card is also fixed and differentiated. For example, the virtual network card Mac address of a kvm-type virtual machine starts at 52:54:00, the virtual network card Mac address of a vmware-type virtual machine starts at 00:0C:29, and so on. Therefore, when a port joins the aggregate group, the characteristic Mac address bits can be determined accordingly. For example, for a virtual network card of a kvm type virtual machine, the corresponding characteristic Mac address bit is "52: 54: 00"; aiming at a virtual network card of a vmware type virtual machine, the corresponding characteristic Mac address bits are '00: 0C: 29', and the like.
In some embodiments of the method 100 for port binding of an aggregation group according to the present invention, the step S130 of adding a port to an aggregation group, determining an address type in a forwarding table of the aggregation group based on the characteristic Mac address bits, and resolving a Mac address and a Mac type corresponding to each packet further includes:
step S131: comparing an address to the characteristic Mac address bits;
step S132: responding to the address matched with the characteristic Mac address bit, and judging that the type corresponding to the address is a virtual network card;
step S133: and in response to that the address is not matched with the characteristic Mac address bit, judging that the type corresponding to the address is a physical network card.
Specifically, in order to determine the address type in the forwarding table of the aggregation group based on the characteristic Mac address bits and resolve the Mac address and its type corresponding to each packet, according to a further embodiment, the identified resolved address is first compared in step S131 with the characteristic Mac address bits determined in step S120. For example, the characteristic Mac address bits corresponding to the virtual network card for a kvm-type virtual machine are "52: 54: 00"; and comparing the corresponding characteristic Mac address bits of the virtual network card of the vmware type virtual machine to be 00:0C: 29. And when the address is matched with the characteristic Mac address bit, namely the first three bits of the address accord with the characteristic Mac address bit, judging that the type corresponding to the address is a virtual network card. And when the address is not matched with the characteristic Mac address bit, namely the first three bits of the address are not the characteristic Mac address bit, judging that the type corresponding to the address is a virtual network card.
Therefore, in summary, the present invention compares the virtual network card and the physical network card by judging the Mac address of the aggregation group forwarding table, and further realizes mutual noninterference between data exchange of the virtual network card and data exchange of the physical network card according to the usage scenario, thereby achieving the purpose of coexistence and usage of the virtual network card and the physical network card.
