Description

Technical Field

[0001] The embodiments of the present invention relate to the field of data communication technology, and in particular to a shared bandwidth speed regulation method, system, electronic device, storage medium and program product. Background Art

[0002] In a virtual cloud network, service sharing bandwidth can enable multiple eips to share a bandwidth speed limit. The usual practice is that the data plane performs traffic statistics for eips on each network element device, and then the control plane periodically obtains traffic statistics for all eips, and then calculates the traffic statistics ratio of all eips under this service sharing bandwidth to assign a speed limit value to each eip, and finally sends it to each network element on the data plane in the form of configuration. The problem with this method is that the control plane actually needs to calculate the corresponding number of speed limits according to the number of eips. The larger the number of configured eips, the longer the calculation time. Usually, the specifications of public cloud eips are relatively large. According to the specifications of 100,000 eips and 10,000 service sharing bandwidths, this time may take about 10s. In addition, the period for the control plane to obtain traffic statistics information for all eips is the adjustment time of traffic changes. If this period is longer, the speed limit fluctuation time will be longer, and the speed limit will be more inaccurate. Summary of the invention

DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] The embodiment of the present invention provides an elastic IP shared bandwidth speed regulation method, which is completed by sinking the eip speed regulation of the shared bandwidth to the network element device on the data plane. The control plane (management platform) computing node actually only calculates the shared bandwidth, which greatly reduces the amount of calculation. Under the same specifications, the speed regulation cycle is shortened by 10 times. Compared with the traditional eip speed regulation method, it solves the problems of frequent traffic changes during the speed regulation cycle, resulting in inaccurate speed limit, large jitter of the speed limit waveform for a long time, and stability.

[0025] Specifically, Figure 1 As shown, it shows a flow chart of the steps of the shared bandwidth speed regulation method provided by an embodiment of the present invention, and the method includes the following steps: S101: Obtain traffic statistics information in a service shared bandwidth instance.

[0026] S102, traverse the eip linked list of the service shared bandwidth instance, and obtain the eip instance of each of the multiple eips included in the service shared bandwidth.

[0027] S103, obtaining traffic statistics information in each eip instance.

[0028] S104: Determine speed adjustment information of each of the multiple EIPs included in the service shared bandwidth based on the traffic statistics information in the service shared bandwidth instance and the traffic statistics information of each of the EIP instances included in the service shared bandwidth.

[0029] In an embodiment of the present invention, the above method is applied to network element devices in a virtual cloud network. In a virtual cloud network, network element devices refer to the basic units that constitute the network, such as routers, switches, etc. In a virtual cloud network, these devices are usually virtualized and can be dynamically configured and expanded. Network element devices are responsible for tasks such as forwarding, routing, and security control of data packets, and are the basis of network communication. Virtual network element devices can be quickly deployed and adjusted according to business needs to improve resource utilization and flexibility.

[0030] Business shared bandwidth means that multiple businesses or services share the same bandwidth resources. This sharing mechanism can improve bandwidth utilization and reduce costs, especially when business traffic fluctuates greatly, bandwidth resources can be allocated more flexibly. Through the management platform corresponding to the cloud platform, the use of shared bandwidth can be monitored and adjusted to ensure business performance.

[0031] In a virtual cloud network, elastic IP (eip) is an important network resource. After an elastic IP is allocated to a user, the user can hold it for a long time, simplifying DNS configuration and maintenance. In addition, the user can bind or unbind the elastic IP to different cloud resources (such as virtual machines, load balancers) at any time to achieve high availability and fault recovery. Through the user interface or API, the user can easily manage the allocation and binding status of the elastic IP.

[0032] Business shared bandwidth allows multiple elastic IPs to share one bandwidth, and centralized speed limits are applied to multiple elastic IPs. It provides regional-level bandwidth sharing and reuse capabilities, and all elastic cloud servers, elastic load balancing and other instances bound to elastic IPs in the same region share one bandwidth resource.

[0033] In the embodiment of the present invention, a speed-limiting service module and a speed-regulating service module can be configured on the network element device. Specifically, there can be multiple speed-limiting service modules, which can be implemented by a speed-limiting service core to receive and process service messages respectively. For a network element device, there can be only one speed-regulating service module, which can be implemented by a separate speed-regulating service core, which is used to perform traffic statistics on the service shared bandwidth corresponding to the network element device and the eip under the service shared bandwidth, and complete the speed regulation of the eip under the service shared bandwidth.

[0034] In the embodiment of the present invention, the eip instance table entry and the shared bandwidth instance table entry can be stored and maintained in the network element device.

[0035] Specifically, the eip instance table entry can be shown in the following table:

[0036] Specifically, the specific parameters of the eip instance table structure are described as follows: struct list_head node indicates that the eip instance adopts a linked list structure.

[0037] uint32_t eip means: the key unique identifier of the business instance, which is also used for hashing in linked lists to solve fast search.

[0038] uint32_t group_id means: shared bandwidth id, which identifies which group_id this eip is associated with.

[0039] struct token token means: eip instance rate limit token bucket configuration.

[0040] struct work_flow_stat stat means: eip instance service flow statistics.

[0041] In the embodiment of the present invention, the eip (elastic IP) instance table entry is a record of an independent public IP address allocated to cloud resources in a virtual cloud network. The eip instance table entry involves the lifecycle management of the eip, including the creation, binding, unbinding, and release of the eip. Users can manage the eip through the management console or API, such as adding or removing the eip, and monitoring the usage of the eip.

[0042] In the embodiment of the present invention, the shared bandwidth instance table entry may be shown in the following table:

[0043] Specifically, the specific parameters of the shared bandwidth instance table entry structure are described as follows: struct list_head group_node indicates that the shared bandwidth instance adopts a linked list structure.

[0044] struct list_head eip_node represents: the linked list structure of eip under this shared bandwidth.

[0045] uint32_t group_id means: shared bandwidth id, the key unique identifier of the shared bandwidth instance, and is also used for linked lists as hashes to solve fast search.

[0046] struct token token means: the speed limit token bucket configuration of the shared bandwidth instance.

[0047] struct work_flow_stat stat means: business flow statistics of shared bandwidth instance.

[0048] In the embodiment of the present invention, the shared bandwidth instance table entry refers to a bandwidth resource pool created in the cloud network, allowing multiple EIPs to share a bandwidth resource. This sharing mechanism can improve bandwidth utilization and reduce costs, especially when the business traffic fluctuates greatly, and bandwidth resources can be allocated more flexibly.

[0049] Based on the shared bandwidth instance table, it is possible to implement speed limits for individual EIPs and provide bandwidth sharing and multiplexing capabilities at the regional level. In the embodiment of the present invention, the shared bandwidth instance table also involves quota limits for shared bandwidth, such as the maximum number of EIPs that can be added to a single shared bandwidth instance. Users can manage shared bandwidth instances through the management console or API, such as creating shared bandwidth, adding or removing EIPs, etc.

[0050] In the embodiment of the present invention, shared bandwidth provides regional bandwidth sharing and multiplexing functions. After creating a shared bandwidth instance, EIP can be added to the shared bandwidth instance. The public network entrance and exit can be uniformly managed through the shared bandwidth, and the bandwidth peak at the Gbps level can be used.

[0051] In the embodiment of the present invention, the speed regulation service module configured on the network element device can determine the service flow statistics corresponding to the shared bandwidth from the parameter of the service shared bandwidth instance: struct work_flow_stat stat. According to the parameter structlist_head eip_node, traverse the eip linked list of the shared bandwidth instance; obtain each eip instance in turn. Then obtain the flow statistics information of each eip from the parameter: struct work_flow_stat stat in each eip instance.

[0052] Finally, based on the traffic statistics in the service shared bandwidth instance and the traffic statistics of each eip instance, the speed adjustment information of each eip included in the service shared bandwidth is determined. In the embodiment of the present invention, the speed regulation service module can also traverse the shared bandwidth instance list to obtain multiple service shared bandwidth instances, and then obtain the eip instances corresponding to each service shared bandwidth.

[0053] In the embodiment of the present invention, the step S104 specifically includes the following sub-steps: S1041: Determine the traffic percentage of each eip in the service shared bandwidth according to the traffic statistics information in the service shared bandwidth instance and the traffic statistics information in each eip instance.

[0054] S1042: Based on the rate limit token bucket configuration information in the service shared bandwidth instance and the traffic percentage of each eip in the service shared bandwidth, determine the rate limit token bucket configuration information of each eip.

[0055] In the embodiment of the present invention, the traffic statistics information in each eip instance can be calculated according to the traffic statistics information stat of the shared bandwidth and the traffic statistics information stat of each eip to determine the traffic percentage percent of each eip in the service shared bandwidth.

[0056] In the embodiment of the present invention, the rate limit token bucket configuration token of each EIP may be further calculated based on the rate limit token bucket configuration information token of the shared bandwidth instance and the calculated percent.

[0057] Specifically, in the embodiment of the present invention, the process of determining the speed adjustment information is as follows: Figure 2As shown, by traversing the eip linked list of the A1 shared bandwidth instance, the eipB1 instance, eipB2 instance...eipBn instance under the A1 shared bandwidth instance can be obtained, and the traffic statistics information can be determined based on the stat of each eip instance.

[0058] Specifically, A1_stat indicates the traffic statistics of A1 shared bandwidth, which is also the sum of all eip traffic statistics of this shared bandwidth. B1_stat indicates the traffic statistics of eip_B1 under A1 shared bandwidth.

[0059] A1_token indicates the token bucket configuration of A1 shared bandwidth.

[0060] B1_token indicates the token bucket configuration of eip_B1 under A1 shared bandwidth.

[0061] Then, B1_token= B1_stat / A1_stat ×A1_token.

[0062] Bn_token=Bn_stat / A1_stat × A1_token.

[0063] Therefore, in the embodiment of the present invention, based on the service sharing bandwidth instance and the eip instance, the eip speed regulation can be transferred to the data on the network element device through the speed regulation service module.

[0064] In the embodiment of the present invention, the speed regulation service module can periodically regulate the speed of the eip. In order to make the speed regulation information as close as possible to the actual traffic situation of each eip and avoid the situation where the token bucket configuration is inconsistent with the actual traffic situation, the speed regulation period can be shortened. In the embodiment of the present invention, the speed regulation period can be set to 1 second.

[0065] In an embodiment of the present invention, the method further comprises the following steps: S11, receiving a service message, and sending the service message to the corresponding target eip.

[0066] S12: Update the traffic statistics information of the eip instance corresponding to the target eip based on the message length of the service message.

[0067] S13: Update the traffic statistics information of the service shared bandwidth instance corresponding to the target eip based on the message length of the service message.

[0068] In the embodiment of the present invention, the above steps S11 to S13 may be executed by a rate limiting service module configured in the network element device.

[0069] In the embodiment of the present invention, the rate-limiting service module receives the service message, sends the service message to the corresponding target eip according to the target eip information carried by the service message, and updates the traffic statistics information stat of the eip instance corresponding to the target eip according to the message length. In addition, the traffic statistics information stat of the service shared bandwidth instance corresponding to the target eip is also updated.

[0070] In the embodiment of the present invention, considering that the speed regulation service module periodically regulates the speed of each EIP, the traffic statistical information based on the corresponding speed regulation service module is also periodically updated. Therefore, in the embodiment of the present invention, the traffic statistical information can be updated and counted periodically based on the speed regulation cycle.

[0071] For example, if the speed adjustment cycle is 10 seconds, then within 10 seconds, the speed limit service module accumulates and updates its traffic statistics according to the message lengths of multiple messages received and sent to eipB1. At the end of a cycle, the traffic statistics update of eipB1 is cleared, and the traffic statistics are accumulated and updated according to the message lengths of multiple messages received and sent to eipB1 in the new cycle.

[0072] Correspondingly, for the A1 shared bandwidth to which eipB1 belongs, its traffic statistics information can also be updated according to the speed adjustment cycle. For example, assuming that the A1 shared bandwidth has three eips, namely eipB1, eipB2 and eipB3, and in the first cycle, eipB1, eipB2 and eipB3 each receive a message, then the traffic statistics information of the assumed A1 shared bandwidth can be cumulatively updated according to the total length of the messages received by each of the three eips. At the end of the cycle, the traffic statistics information of the A1 shared bandwidth is updated and cleared, and its traffic statistics information is cumulatively updated according to the message lengths of multiple messages received and sent to eipB1, eipB2 and eipB3 in the new cycle.

[0073] In the embodiment of the present invention, before step S11, the method further includes the following steps: S21, based on the IP information carried by the service message, traverse the hash linked list to match the eip instance, and determine the target eip if the eip instance is matched; S22: Determine a corresponding service shared bandwidth instance based on the service shared bandwidth information recorded by the eip instance.

[0074] In the embodiment of the present invention, after receiving the service message, the rate limiting service module can perform hash calculation based on the IP in the service message as the key, and then traverse the hash linked list to match the eip instance. If it fails, the packet is lost and the module exits. If it succeeds, the eip instance is hit to determine the target eip.

[0075] After hitting the eip instance, you can find the shared bandwidth instance based on the group_id recorded on the eip instance.

[0076] For example, after performing hash calculation based on the IP information in the service message and traversing the hash linked list, the eipB1 instance is matched, and the A1 shared bandwidth instance corresponding to the eip instance is determined according to the uint32_t group_id parameter in the eipB1 instance.

[0077] In the embodiment of the present invention, when an eip instance is matched, it is necessary to further determine whether to send the service message to the target eip based on the rate-limiting token bucket of the eip instance. Specifically, in the embodiment of the present invention, the method further includes the following steps: S23: When an eip instance is matched, determine whether a packet is lost based on the rate limit token bucket configuration information recorded by the eip instance.

[0078] S24: When packet loss is determined, discard the service message.

[0079] In the embodiment of the present invention, the rate-limited token bucket configuration can be used to control the transmission rate of data packets, allowing data to be transmitted at a higher rate in a certain time interval and at a lower rate in other time intervals, thereby achieving traffic shaping and rate limiting. When there are enough tokens in the token bucket, burst traffic can be processed quickly without discarding data packets due to fixed rate limits.

[0080] In the embodiment of the present invention, the percentage of traffic occupied by each eip instance and the traffic statistics of the shared bandwidth can be calculated. This percentage can be used to dynamically adjust the speed limit token bucket configuration of each eip, thereby achieving more refined bandwidth allocation.

[0081] In the embodiment of the present invention, by configuring the rate-limiting token bucket, the utilization efficiency of network resources can be improved while ensuring network stability. For example, when the network load is light, more data packets can be allowed to pass, and when the network load is heavy, the transmission of data packets is limited to avoid network congestion.

[0082] In the embodiment of the present invention, in the scenario of sharing bandwidth, different eip instances may have different service quality requirements. Through the rate-limiting token bucket configuration, token buckets of different sizes can be allocated to different eip instances, thereby ensuring the service quality of high-priority services.

[0083] In the embodiment of the present invention, by configuring a rate-limiting token bucket to limit the bandwidth usage of each eip instance, it is possible to prevent individual instances from abusing shared bandwidth resources, thereby ensuring fair usage of all instances.

[0084] In the embodiment of the present invention, it can be determined whether to limit the packet loss according to the token and message length of the eip instance and the token bucket algorithm. Before determining whether to limit the packet loss, the flow information can be updated according to the message length of the data packet, that is, step S24 is performed after step S13, so that even if the packet loss is determined, the message can still be counted in the flow statistics. So that the flow statistics information can better reflect the flow demand of the eip.

[0085] In the shared bandwidth speed regulation method provided by the embodiment of the present invention, the speed regulation of the eip under the shared bandwidth is sunk to the data plane and completed on the network element device. Accordingly, the computing node of the management platform of the control plane actually only needs to calculate the traffic statistics and speed regulation of the shared bandwidth, so the amount of calculation is greatly reduced, and the speed regulation based on the shared bandwidth can be completed within an adjustment period of 1 second. For example, the configuration specifications are calculated according to the specifications of 100,000 eips and 10,000 shared bandwidths. The traditional shared bandwidth speed regulation method has an adjustment period of about 10 seconds. Since the traffic changes irregularly, the proportion of different eip traffic under the same shared bandwidth changes at any time. If it is adjusted once every 10 seconds, the network speed waveform of each eip will fluctuate greatly. By adopting the technical solution provided by the embodiment of the present invention, the shared bandwidth speed regulation can be completed within 1 second, the impact on traffic fluctuations is small, and the waveform is basically stable.

[0086] Another shared bandwidth speed adjustment method is also provided in the embodiment of the present invention. Figure 3 As shown, it shows a flow chart of another shared bandwidth speed adjustment method provided by an embodiment of the present invention, the method comprising the following steps: S301, obtaining traffic statistics information of each service shared bandwidth, where the traffic statistics information represents the sum of traffic statistics information of all EIPs under the service shared bandwidth within a unit time.

[0087] S302: Determine rate limit token bucket configuration information of each service shared bandwidth based on traffic statistics information of each service shared bandwidth.

[0088] In the embodiment of the present invention, the above steps S301-S302 can be executed by the management platform corresponding to the virtual cloud network. For the management platform, only traffic statistics and speed adjustment of the shared bandwidth are needed, which greatly reduces the amount of calculation and can complete the speed adjustment based on the shared bandwidth within the adjustment period of 1 second.

[0089] Based on the same inventive concept, an embodiment of the present invention further provides a service sharing bandwidth speed regulation system, the system comprising: a network element device and a management platform, a rate limiting service module and a speed regulation service module are configured on the network element device, the rate limiting service module of the network element device is used to: receive a service message, and send the service message to a corresponding target eip; update the traffic statistics information of the eip instance corresponding to the target eip based on the message length of the service message; update the traffic statistics information of the service sharing bandwidth instance corresponding to the target eip based on the message length of the service message; The speed regulation service module of the network element device is used to: obtain traffic statistics information in a service shared bandwidth instance; traverse the eip linked list of the service shared bandwidth instance to obtain the eip instances of each of the multiple eips included in the service shared bandwidth; obtain traffic statistics information in each eip instance; based on the traffic statistics information in the service shared bandwidth instance and the traffic statistics information of each eip instance included in the service shared bandwidth, determine the speed regulation information of each of the multiple eips included in the service shared bandwidth; The management platform is used to obtain traffic statistics information of each service shared bandwidth, where the traffic statistics information represents the sum of traffic statistics information of all EIPs under the service shared bandwidth within a unit time; Based on the traffic statistics information of each service shared bandwidth, the rate limit token bucket configuration information of each service shared bandwidth is determined.

[0090] Specifically, the design flow chart of the speed limit service module is as follows: Figure 4 As shown, in the embodiment of the present invention, the speed limit service module (speed limit service core) receives a data packet, and uses the IP of the message in the data packet as a key to determine whether it can match the speed limit eip instance list. If matched, the shared bandwidth instance is found according to the group_id recorded on the eip instance, and the stat traffic statistics of the eip instance are updated according to the message length. The stat traffic statistics of the shared bandwidth instance are further updated according to the message length. Finally, according to the token of the eip instance and the message length, it is determined according to the token bucket algorithm whether to limit the packet loss. If it is determined that the packet loss is required, the packet loss is performed. If it is determined that the packet loss is not required, the data packet is sent to the corresponding eip.

[0091] In the embodiment of the present invention, there may be multiple rate-limiting service modules, which process multiple data packets sent to the virtual cloud network respectively.

[0092] In the embodiment of the present invention, after determining the eip instance matched by the data packet, the speed limit service module updates the traffic statistics information of the eip instance and the corresponding shared bandwidth instance according to the message length of the data packet. Whether the data packet is subsequently dropped or sent, it does not affect the traffic statistics of the data packet that should actually be sent to the eip. The recorded traffic statistics information can more realistically reflect the size of the traffic actually sent to the eip, so that when the speed regulation information is subsequently determined by the speed regulation service module, it can be more accurately close to the actual situation of the traffic sent to each eip.

[0093] Specifically, the design flow chart of the speed regulation business module is as follows: Figure 5 As shown, in the embodiment of the present invention, the speed regulation service module can traverse the shared bandwidth instance list, obtain each service shared bandwidth instance, and then obtain the traffic statistics stat of the shared bandwidth, and then traverse the eip list of the shared bandwidth instance, obtain each eip instance in turn, and obtain the traffic statistics stat of the eip, and then calculate the traffic percentage percent according to the stat of the shared bandwidth and the stat of the eip, and finally calculate the speed limit token bucket configuration token on the eip according to the speed limit token bucket configuration token on the shared bandwidth instance and the calculated percent.

[0094] In the embodiment of the present invention, the management platform only needs to perform traffic statistics and speed regulation of the shared bandwidth, so the amount of calculation is greatly reduced, and the speed regulation based on the shared bandwidth can be completed within an adjustment period of 1 second.

[0095] Therefore, in the embodiment of the present invention, the relationship between the eip and the service shared bandwidth is recorded on the data plane (network element device), the service core (speed limit service module) of the data plane records the traffic statistics, and then the speed regulation core (speed regulation service module) of the data plane allocates the actual speed limit value of each eip in proportion according to the traffic statistics of the eip under the service shared bandwidth. The data plane then directly calculates the traffic statistics of the service shared bandwidth, and then when the control plane (management platform) directly interacts with the data plane, it gets the statistics of the service shared bandwidth, and there is no need to calculate the eip under the service shared bandwidth, nor is there a need to re-issue the configuration of the eip after calculation. The calculation amount is changed from the number of eips to the number of service shared bandwidths. Usually, a service shared bandwidth includes dozens to hundreds of eips, and the calculation time is greatly reduced, making the speed limit fluctuation smaller and more accurate.
