At present, the capability of cloud computing is getting stronger, and a router which is used as a gateway before can be completely replaced by a gateway in a Network Function Virtualization (NFV) form, which is referred to as an NFV gateway for short. However, since the NFV gateway also exists in the server in a virtual machine state, the NFV gateway and the user virtual machine need to share hardware resources of the server. If the number of the NFV gateways is too large, the hardware resources which can be used by the user virtual machine are too small; if the number of the NFV gateways is too small, the network resources of the user virtual machine may be insufficient, and the user virtual machine may surf the internet and be stuck. Therefore, how to dynamically adjust the number of NFV gateways in the server is a considerable problem.
When a certain service normally running by a user faces burst traffic access, a virtualization management platform can actively detect the user traffic load condition, when the performance of a virtual machine where the service is located is found to be insufficient, the virtual machine is quickly copied, the virtual machine is matched with load balancing (L ad Balance, L B) equipment to provide services to the outside, and after an access peak is over, the virtual machine can be dynamically contracted and the surplus virtual machine is deleted, so that the situation that computing resources move as needed is realized.

The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
The gateway adjusting method provided in the embodiment of the present application may be applied to an electronic device, for example, a server, as shown in fig. 1, which is a schematic structural diagram of the server, and includes a plurality of virtual machines, a part of the virtual machines belongs to a user network 1, a part of the virtual machines belongs to a user network 2, and the like, the server further includes a plurality of NFV gateways (NFV gateways 1 to NFV gateway n shown in fig. 1), a data analyzer, and a virtual switch, where the plurality of user networks, the plurality of NFV gateways, and the data analyzer are connected to the virtual switch through a virtual network card tap port. The NFV gateway is also a virtual machine, and only has different functions from those of the virtual machine belonging to the user network; the virtual machine in the user network is used for forwarding the traffic of the user to the device corresponding to the destination IP through the NFV gateway, and forwarding the traffic of the user to the data analyzer; the data analyzer is installed on the virtual machine and used for analyzing the received flow of the user; for the NFV gateway, when the data analyzer determines that the traffic of the NFV gateway exceeds the traffic migration threshold, the data analyzer notifies the Hypervisor in the server, the Hypervisor adds an NFV gateway in the server, and then migrates the traffic of the NFV gateway to the added NFV gateway. Therefore, the flexible adjustment of the number of the NFV gateways is realized, the flow on the NFV gateway is successfully migrated to the newly added NFV gateway, the pressure of the NFV gateway with heavier burden is effectively relieved, and in addition, the NFV gateway is newly added, so that more available network resources can be provided for the service of the user.
In addition, when the data analyzer determines that the sum of the traffic of the NFV gateways does not exceed the traffic migration threshold, the data analyzer notifies the Hypervisor to select one NFV gateway from the NFV gateways, then migrates the traffic of the remaining NFV gateways from the NFV gateways to the selected NFV gateway, and deletes the remaining NFV gateways. Thus, when the traffic on a plurality of NFV gateways is small and the sum of the traffic of the NFV gateways is small, it indicates that such many NFV gateways are not needed currently, and at this time, by implementing the above-mentioned process, the number of NFV gateways is dynamically adjusted, and the traffic of other NFV gateways is smoothly migrated to the selected NFV gateway, and because the redundant NFV gateways are deleted, the virtual machine of the user network can share more hardware resources on the server.
The gateway adjusting method provided in the present application is explained in detail below.
Referring to fig. 2a, fig. 2a is a flowchart of a gateway adjusting method shown in the present application. The gateway adjusting method is applied to a server, the server comprises a plurality of NFV gateways, and the server can implement the method and comprises the following steps:
s201, when the fact that the flow of the current NFV gateway exceeds the flow migration threshold is determined, the NFV gateway is newly added to the server.
Specifically, probe software is installed on the NFV gateway in the server, and the probe software can send traffic flowing through the NFV gateway to the data analyzer through a netflow or sflow protocol. The data analyzer judges whether the traffic of the NFV gateway exceeds a traffic migration threshold, and when the traffic exceeds the traffic migration threshold, it indicates that the user traffic currently carried by the NFV gateway is too much, and there may be a situation that the NFV gateway crashes due to overload work.
It should be noted that the traffic migration thresholds corresponding to different NFV gateways may be the same or different, and may be specifically set according to actual situations.
Optionally, when an NFV gateway is newly added, the number of the newly added NFV gateways may be configured according to actual conditions, but it is to be ensured that hardware resources of a server shared by a user network are not particularly greatly affected. In general, when an NFV gateway is newly added, it can be added one by one.
S202, migrating the flow of the current NFV gateway to the newly added NFV gateway.
In a specific implementation, after an NFV gateway is newly added, a traffic that does not exceed a traffic migration threshold of the newly added NFV gateway in the NFV gateway may be migrated to the newly added NFV gateway, which is shown in fig. 2b, and the current NFV gateway is taken as the NFV gateway 1 for an example, so that the traffic on the NFV gateway 1 is migrated to the newly added NFV gateway. Therefore, the dynamic adjustment of the number of the NFV gateways in the server is realized, and the smooth migration of the flow is realized; in addition, through the traffic migration, the situation that the message is lost due to too much traffic on the NFV gateway and cannot be processed in time when the traffic is on the previous NFV gateway does not occur.
Alternatively, before implementing step S202, the method may be implemented according to the flow shown in fig. 3, including the following steps:
s301, obtaining the traffic information of the current NFV gateway traffic, where the traffic information includes the network identifiers of different user networks.
S302, the flow of the current NFV gateway is sequenced according to the network identification, and the flow meeting the flow migration condition in the sequencing result is migrated to the newly added NFV gateway.
In specific implementation, the NFV gateway in the server is configured to forward traffic of a packet sent by a user in a user network, so that the traffic information may include network identifiers of different user networks, and when analyzing the traffic, the traffic under the network identifier may be obtained by summing the traffic of the same network identifier and recorded as the network traffic, so as to obtain network traffic corresponding to each network identifier, and then the network traffic corresponding to each network identifier is sorted, so that the maximum network traffic is determined, and then the traffic of the user network corresponding to the network identifier corresponding to the maximum network traffic is migrated to the newly added NFV gateway.
It should be noted that different user networks have different Network identities, and if all the user networks are Virtual local Area networks (Virtual L environmental Area networks, V L AN), the V L AN IDs of the different user networks are different, and if all the user networks are Virtual Extensible L environmental Area networks (VX L AN), the VX L AN IDs of the different user networks are different.
For example, the current NFV gateway serves 3 user networks, and the network identifiers of the 3 user networks are respectively V L ANID1, V L AN ID2, and V L AN ID3, then the current NFV gateway traffic information is summarized to include traffic of V L AN ID1, so as to obtain network traffic flow1, according to this method, network traffic flow2 corresponding to V L AN ID2 and network traffic flow3 corresponding to V L AN ID3 can be obtained, then the 3 network traffic is subjected to ranking processing, and if flow1< flow2< flow3, the traffic of the user network corresponding to V L AN ID3 in the current NFV gateway is migrated to the newly added NFV gateway.
Optionally, in a ranking result obtained after ranking based on the network identifiers, if the sum of the traffic of the user networks corresponding to TOP m network identifiers does not exceed the traffic migration threshold of the newly added NFV gateway, the traffic of the user networks corresponding to the previous m network identifiers may be migrated to the newly added NFV gateway, where the value of m is determined according to the result of the actual sum of the traffic.
Optionally, if there may be a case that the granularity of traffic migration based on the V L AN ID or the VX L AN ID is too coarse, and there may be a case that the traffic of a single user network is still higher than the traffic migration threshold, it indicates that the traffic of the user network cannot be migrated to the newly added NFV gateway, and to avoid this, the traffic information provided in this application further includes a source IP address and a destination IP address, and when step S302 is executed, the following process may be further performed:
and if the traffic meeting the traffic migration condition exceeds the traffic migration threshold of the newly added NFV gateway, sequencing the current traffic of the NFV gateway according to the source IP address and the destination IP address, and migrating the traffic meeting the traffic migration condition in the sequencing result to the newly added NFV gateway.
In specific implementation, analyzing traffic may be understood as analyzing a packet, where the packet generally carries a source IP address and a destination IP address, and correspondingly, the analyzed traffic information may also include the source IP address and the destination IP address. Then, after screening out the user network corresponding to the network identifier with the largest traffic based on the flow of fig. 3, if it is determined that the traffic of the user network flowing on the current NFV gateway still exceeds the traffic migration threshold, the flow of migrating the traffic of the user network to the newly added NFV gateway is not executed, but the following process is executed: and based on the source IP address and the destination IP address, reordering the traffic on the current NFV gateway, and then migrating the maximum traffic in the ordering result to the newly added NFV gateway.
For better understanding of the embodiment, if it is determined that traffic of a user network corresponding to V L AN ID1 served on a current NFV gateway exceeds a traffic migration threshold of a newly added NFV gateway, indicating that the traffic of the user network corresponding to V L AN ID1 cannot migrate to the newly added NFV gateway, then sorting the traffic on the current NFV gateway according to IP addresses, for example, traffic information of the traffic on the current NFV gateway includes IP addresses of 5 combinations, such as { source IP1, destination IP1}, { source IP2, destination IP2}, { source IP3, destination IP3}, { source IP3, destination IP3}, traffic under each combination is counted respectively, if it is determined that the source IP address is source IP3, the destination IP address is destination IP3, if it is determined that the source IP address is source IP3, the traffic of the destination IP address is destination IP3, the traffic of the source IP address is 3, the destination IP flow is sorted, and the destination IP flow is 3, if the source IP flow is determined that the source IP address is 3, the flow is 3, the destination flow is sorted, the flow is 3, the flow is sorted by 3, and the flow of the destination flow3, the flow is migrated as three new NFV gateway 3, the flow is obtained by sorting, and 3, the flow is 3.
Optionally, after the traffic on the current NFV gateway is sorted based on the source IP address and the destination IP address to obtain a sorting result, if the sum of the traffic corresponding to TOP N IP address combinations in the sorting result does not exceed the traffic migration threshold of the newly added NFV gateway, the traffic corresponding to the TOP N IP address combinations in the sorting result may be migrated to the newly added NFV gateway at this time, where the value of N needs to be determined according to the sum of the traffic corresponding to the IP address combinations. Assuming that the total flow sum of flow11+ flow22 in the IP combination is still smaller than the flow migration threshold, the flows corresponding to the source IP1 and the destination IP1, and the flows corresponding to the source IP2 and the destination IP2 may be migrated to the newly added NFV gateway.
Optionally, in this embodiment, a process of migrating the traffic of the current NFV gateway to the newly added NFV gateway may also be implemented according to the process shown in fig. 4, where the process includes the following steps:
s401, obtaining the traffic information of the current NFV gateway traffic, wherein the traffic information comprises a source IP address and a destination IP address.
S402, sequencing the flow of the current NFV gateway according to the source IP address and the destination IP address, and migrating the flow meeting the flow migration condition in the sequencing result to the newly added NFV gateway.
In specific implementation, the IP addresses may also be directly sequenced, the source IP address and the destination IP address are directly obtained from the traffic information of the traffic carried by the current NFV gateway, and then sequencing is performed according to a combination of the source IP address and the destination IP address, which may specifically refer to the IP address-based sequencing and migration process referred in fig. 3, and details are not described here.
Optionally, after determining that the traffic of the current NFV gateway exceeds the traffic migration threshold in step S201, before performing adding an NFV gateway in the server, the process shown in fig. 5a may also be performed, which includes the following steps:
s501, determining the flow of other NFV gateways in the server.
S502, if the traffic of any NFV gateway is lower than the traffic migration threshold, migrating a part of the traffic of the current NFV gateway to the NFV gateway, where a sum of the part of the traffic and the traffic of the NFV gateway is smaller than the traffic migration threshold.
In specific implementation, there may be a case where the traffic of the current NFV gateway is more, but the traffic of other NFV gateways is less, in this scenario, the flow of the newly added NFV gateway may not be executed, the traffic of other NFV gateways except the current NFV gateway in the current server may be determined, and if the traffic of any NFV gateway in the other NFV gateways is lower than the traffic migration threshold, the traffic of the current NFV gateway may be migrated to the NFV gateway, where, during traffic migration, the sum of the migration traffic migrated to the NFV gateway and the traffic of the NFV gateway is to be ensured to be smaller than the traffic migration threshold, and then the NFV gateway from which the traffic is migrated is deleted. For example, the current server has 5 NFV gateways, namely, NFV gateway 1, NFV gateway 2, NFV gateway 3, NFV gateway 4, and NFV gateway 5, where it is determined that the traffic of NFV gateway 1 exceeds the traffic migration threshold, and then it is determined that the traffic of NFV gateway 3 in the remaining 4 NFV gateways is smaller than the traffic migration threshold, the traffic on NFV gateway 1 may be migrated to NFV gateway 3, but it is to be ensured that the sum of the traffic migrated from NFV gateway 1 and the current traffic of NFV gateway 3 is smaller than the traffic migration threshold, please refer to fig. 5 b. In a specific implementation, when performing traffic migration, the traffic migration may be performed according to the traffic provided in the embodiments related to fig. 3 to 4, but after the migration to the NFV gateway 3 is ensured, the traffic of the NFV gateway 3 cannot exceed the traffic migration threshold.
If it is determined that the traffic on the other NFV gateways is closer to the traffic migration threshold, i.e., there is no way to receive the traffic of the current NFV gateway, the traffic migration procedure shown in fig. 2 is performed. Therefore, traffic processing resources are reserved for other NFV gateways, and message loss caused by overload work due to the fact that the traffic of the current NFV gateway is received is avoided.
By implementing the flow shown in fig. 5a, smooth migration of traffic is realized without adding an NFV gateway, and the processing load of the current NFV gateway is reduced.
Optionally, based on any of the above embodiments, the gateway adjusting method provided by the present application may further include a process shown in fig. 6a, including the following steps:
s601, if it is determined that the total traffic of the NFV gateways does not exceed the traffic migration threshold, selecting an NFV gateway from the NFV gateways.
And S602, migrating the residual NFV gateway traffic to the selected NFV gateway, and deleting the residual NFV gateway.
In order to avoid this situation, in this embodiment, after receiving traffic of NFV gateways on a server, if it is determined that the traffic of a current NFV gateway is relatively small and smaller than a traffic migration threshold, a data analyzer may wait to receive traffic of a next NFV gateway, if the traffic of consecutive L NFV gateways is still smaller than the traffic migration threshold, notify a virtual machine monitor Hypervisor to select one NFV gateway from among L NFV gateways, then migrate traffic of other NFV gateways to the selected NFV gateway, and then delete the NFV gateway, which is indicated by a virtual machine monitor that the traffic of other NFV gateways among L NFV gateways is less than a traffic migration threshold, and then delete the NFV gateway, which is indicated by a virtual machine monitor that the virtual machine monitor occupies a virtual network gateway 2 and a virtual network gateway 2, and a virtual network gateway, and the virtual machine monitor delete the virtual network gateway, which is indicated by a virtual machine monitor that the virtual machine monitor deletes NFV gateway and NFV gateway 2, and a virtual machine gateway, thus, the virtual machine monitor deletes the virtual machine gateway and NFV gateway, and the NFV gateway, which are not only the virtual machine gateway deletion of the NFV network gateway is considered by a virtual machine is considered as a virtual machine, the virtual machine monitor, the NFV network, the virtual machine is deleted virtual machine, the NFV.
It should be noted that, in any embodiment of the present application, when determining the traffic of the NFV gateway, the traffic flowing through the NFV gateway within a set time period is detected.
