The public network IP resource in the virtual network resource provided by the cloud manufacturer is an elastic public network IP, namely the public network IP address which can be independently applied can be supported to dynamically bind and unbind with resources such as a cloud host, a container, load balancing, an NFV instance and the like. The main function of the elastic public network IP is to shield example faults; when an instance fails, the elastic public network IP drifts to a redundant instance in a manual configuration mode, so that the purpose of quickly responding to the failure is achieved. The current public network bandwidth setting has the forms of year and month, configuration or usage, and the forms correspond to a fixed bandwidth upper limit. However, the demand of the user service on the public network bandwidth is dynamically changed, and the situation of steep increase of the service volume possibly occurs, and the fixed upper bandwidth limit obviously cannot meet the demand of the user. In response to this problem, the present disclosure devised a bandwidth adjustment method.
The following describes the technical scheme of the embodiments of the present disclosure in detail:
referring to fig. 2, a bandwidth adjustment method according to an exemplary embodiment provided by the present disclosure may include the steps of:
Step S210, obtaining user configuration parameters and current instantaneous bandwidth, wherein the user configuration parameters comprise: bandwidth adjustment triggering conditions and bandwidth adjustment strategies;
step S220, determining the current public network bandwidth utilization rate according to the current instantaneous bandwidth and the original bandwidth upper limit;
Step S230, determining whether the bandwidth adjustment triggering condition is met currently according to the current public network bandwidth utilization rate;
step S240, under the condition that the bandwidth adjustment triggering condition is met, the bandwidth is correspondingly adjusted according to the bandwidth adjustment strategy.
In the bandwidth adjustment method provided by the present exemplary embodiment, a user may configure parameters according to service requirements, that is, input a bandwidth adjustment triggering condition and a bandwidth adjustment policy, and the monitoring system obtains a current instantaneous bandwidth; the cloud server determines the current public network bandwidth utilization rate according to the received current instantaneous bandwidth and the original bandwidth upper limit; determining whether the received bandwidth adjustment triggering condition is met or not according to the current public network bandwidth utilization rate; and under the condition that the bandwidth adjustment triggering condition is met, correspondingly adjusting the bandwidth according to the received bandwidth adjustment strategy. On the one hand, when the service is suddenly increased, the bandwidth adjustment efficiency and the instantaneity can be improved, and meanwhile, the service loss such as lost data caused by bandwidth limitation can be avoided. On the other hand, when the service is less, the bandwidth is reduced, so that the resource waste is avoided, and the user cost is reduced. In addition, the manpower resources are saved, and the cost is further reduced.
In another embodiment, the above steps are described in more detail below.
In step S210, the user configuration parameters and the current instantaneous bandwidth are acquired. In this example embodiment, the user configuration parameters may include: bandwidth adjustment triggering conditions and bandwidth adjustment strategies; the bandwidth adjustment trigger condition may be used to determine under what conditions an adjustment of bandwidth is to be made. It may comprise a bandwidth up trigger condition, i.e. a trigger condition that increases the upper limit of the bandwidth, for the case where the user traffic continues to increase. A bandwidth down trigger condition, i.e. a trigger condition that reduces the upper limit of the bandwidth, may also be included, which is for the case of less user traffic, i.e. the traffic idle period.
Further, in this example embodiment, the bandwidth up-regulation trigger condition may include a public network bandwidth usage upper limit, where public network bandwidth usage may be defined as a percentage of the instantaneous bandwidth to the original bandwidth upper limit. The upper limit of the bandwidth utilization rate of the public network can be set as a threshold value, or the upper limit of the bandwidth utilization rate of the public network can be set as a plurality of threshold values, and each threshold value can be used as one of the triggering conditions of bandwidth up-regulation. For example, the upper limit of the public network bandwidth usage is set to 70%, 80%, 90%, at which time each threshold needs to correspond to a respective duration requirement to trigger the bandwidth up-regulation mechanism. The bandwidth up-regulation triggering condition may further include a first duration limit, where the first duration limit may be set to a threshold, or the first duration limit may be set to a plurality of thresholds, where each threshold corresponds to an upper limit of a public network bandwidth usage, and the two indexes are used as a set of bandwidth up-regulation triggering conditions. For example, the upper limit of the public network bandwidth utilization is set to 70%, and the first duration limit is set to 7200s; the upper public network bandwidth usage limit is set to 80% and the first duration limit is set to 3600s.
In this example embodiment, the bandwidth down trigger condition may include a lower limit of public network bandwidth usage, where public network bandwidth usage may be defined as a percentage of the instantaneous bandwidth to the upper limit of the original bandwidth. The upper limit of the bandwidth utilization rate of the public network can be set as a threshold value, or the upper limit of the bandwidth utilization rate of the public network can be set as a plurality of threshold values, and each threshold value can be used as one of the bandwidth down-regulation triggering conditions. For example, the upper limit of the public network bandwidth usage is set to 20%, 30%, 35%, at which time each threshold needs to correspond to a respective duration requirement to trigger the bandwidth downregulation mechanism. The bandwidth downregulation triggering condition may further include a second duration limit, where the second duration limit may be set to a threshold, or the second duration limit may be set to a plurality of thresholds, where each threshold corresponds to an upper limit of a public network bandwidth usage, and the two indexes are used as a set of bandwidth downregulation triggering conditions. For example, the public network bandwidth usage lower limit is set to 20% and the second duration limit is set to 3600s.
In this example embodiment, the bandwidth adjustment policy may include a bandwidth adjustment manner and a bandwidth adjustment base, and the bandwidth adjustment manner may be up-or down-regulated, i.e., increased or decreased. The bandwidth adjustment manner may be stepwise up-adjustment or stepwise down-adjustment, for example, bandwidth is adjusted to the target bandwidth in two or three times, wherein the bandwidth adjustment amounts of the adjacent two times may be the same or different. For example, the current bandwidth has an upper limit of 100Mbps, the target bandwidth is 130Mbps, the bandwidth is adjusted in three times, and when the bandwidth adjustment amounts of two adjacent times are the same, the adjustment amount is 10Mbps each time; when the bandwidth adjustment amounts of two adjacent times are different, 5Mbps can be adjusted for the first time, 10Mbps can be adjusted for the second time, and 15Mbps can be adjusted for the third time. In addition, bandwidth adjustment may be performed according to a set time, that is, the current bandwidth upper limit may be adjusted to the target bandwidth within a set time. The present exemplary embodiment is not particularly limited to a specific bandwidth adjustment manner.
In this example embodiment, the bandwidth adjustment base may be flexibly set according to traffic, for example, the bandwidth adjustment base may be set as a percentage of the bandwidth adjustment base. Preferably, the bandwidth adjustment radix percentage may be set to 10% -30%. When the percentage of the bandwidth adjustment base is set to 20%, the upper limit of the original bandwidth is 100Mbps, and the upper limit of the adjusted bandwidth is 120Mbps. The bandwidth adjustment base may also be set to a fixed value or a range of values. When the bandwidth adjustment base is a range of values, a value may be randomly selected from the range of values as the bandwidth adjustment value, or the upper limit and the lower limit of the range of values may be correlated to obtain the bandwidth adjustment value, for example, an average value of the upper limit and the lower limit may be taken as the bandwidth adjustment value. The present exemplary embodiment is not particularly limited thereto.
In this example embodiment, the obtaining the user configuration parameter may be that the cloud backend server receives the configuration parameter input by the user on a web service page of the cloud service or the cloud client. The current instantaneous bandwidth can be obtained by the cloud background server receiving the instantaneous bandwidth of the user obtained by the cloud monitoring server in real time. Cloud monitoring is related service of cloud service, and through cloud monitoring (CloudMonitor), an example, a system disk, public network bandwidth and other monitoring schemes are formulated, so that public network bandwidth information of a user can be obtained in real time.
The web service page or the cloud client of the existing cloud service does not have bandwidth adjustment triggering conditions and bandwidth adjustment policy configuration options. Cloud service ECS (Elastic Compute Service) mainly includes the following functional components:
examples: the virtual server is equivalent to a virtual server, and comprises basic components such as a CPU, a memory, an operating system, network configuration, a disk and the like. The computing performance, the memory performance and the applicable service scene of the instance are determined by the instance specification, and the specific performance indexes comprise the number of cores of the instance vCPU, the memory size, the network performance and the like.
Mirror image: providing an operating system of the instance, initializing application data and pre-installed software. The operating system supports multiple Linux releases and multiple Windows Server versions.
And (3) block storage: the block device type product has the characteristics of high performance and low time delay. Cloud disks based on a distributed storage architecture and local disks based on physical machine local storage are provided.
Snapshot: and a data state file of a cloud disk at a certain time point. Is commonly used for data backup, data recovery, custom mirroring, etc.
Safety group: the virtual firewall is used for setting the network access control of the instances.
Network: proprietary network (Virtual Private Cloud): logically completely isolated private networks on the cloud. The private network IP address range, the configuration routing table, the gateway and the like can be allocated by the user. Classical network: all classical network type instances are built on a common underlying network. And uniformly planning and managing network configuration by cloud manufacturers.
In this example embodiment, a developer tool of the cloud server ECS API is called, so that an input enabling end of the configuration parameters and a corresponding configuration window are configured on a web service page or a cloud client of the cloud service. For example, when a dynamic bandwidth upper limit adjusting button is opened when a public network IP page is created, once a user enables the switch, a plurality of adjusting index input boxes are added to the page for the user to input configuration parameters.
In this example embodiment, the user is interacted with by configuring the input enabling end of the configuration parameter and the corresponding configuration window on a web service page of the cloud service or a cloud client.
In step S220, a current public network bandwidth utilization is determined according to the current instantaneous bandwidth and the original bandwidth upper limit. In this example embodiment, the original bandwidth upper limit may be a bandwidth upper limit before adjustment, which may be a default bandwidth upper limit or a bandwidth upper limit after the last adjustment. The current instantaneous bandwidth is obtained through real-time monitoring of cloud monitoring.
In the present exemplary embodiment, referring to fig. 3, the current public network bandwidth usage rate may be determined through steps S310 to S330.
In step S310, an original bandwidth upper limit is acquired. In this example embodiment, after the user purchases the cloud resources, the cloud service may allocate respective bandwidth resources to the user, each cloud resource having a corresponding upper bandwidth limit in terms of user payment (per year, month, configuration, or usage). The configured upper bandwidth limit may be referred to as the original upper bandwidth limit. The upper bandwidth limit set when the user performs initial bandwidth configuration on the cloud resource can be used as the original upper bandwidth limit. The upper bandwidth limit that the user reconfigures during use may also be referred to as the original upper bandwidth limit. The original bandwidth upper limit of the present example may be dependent on cloud resource usage.
In step S320, a proportional relationship between the current instantaneous bandwidth and the original bandwidth upper limit is calculated. In this example embodiment, the current instantaneous bandwidth may be calculated as a percentage of the upper limit of the original bandwidth. Or setting an error threshold value, calculating the sum of the current instantaneous bandwidth and the error threshold value, and finally calculating the percentage of the sum result to the upper limit of the original bandwidth. The present example is not particularly limited thereto.
In step S330, the current public network bandwidth utilization is determined according to the proportional relationship. In this example embodiment, the proportional relationship may be directly used as the current public network bandwidth utilization; the proportional relation can be corrected according to experience, and the corrected result is used as the current public network bandwidth utilization rate.
In step S230, it is determined whether the bandwidth adjustment triggering condition is currently satisfied according to the current public network bandwidth usage rate. In this example embodiment, the bandwidth adjustment trigger condition may include one or both of a bandwidth up trigger condition and a bandwidth down trigger condition.
In this example embodiment, the process of determining whether the bandwidth up trigger condition is satisfied may be: firstly, determining whether the current public network bandwidth utilization exceeds the public network bandwidth utilization upper limit; secondly, determining whether a duration exceeding the upper limit of the public network bandwidth utilization exceeds the first duration limit; and finally, if the conditions are met at the same time, determining that the bandwidth adjustment triggering condition is met. For example, if the upper limit of the public network bandwidth utilization is 80%, the current public network bandwidth utilization is 85%, and the duration of the state that the public network bandwidth utilization exceeds 80% exceeds 3600s, it is determined that the bandwidth up-adjustment triggering condition is met, and the bandwidth up-adjustment mechanism is triggered.
In this example embodiment, the process of determining whether the bandwidth down-adjustment trigger condition is satisfied may be: firstly, determining whether the current public network bandwidth utilization rate is lower than the lower limit of the public network bandwidth utilization rate; secondly, determining whether a duration of time below the lower limit of the public network bandwidth usage exceeds the second duration limit; and finally, if the conditions are met at the same time, determining that the bandwidth adjustment triggering condition is met. For example, if the lower limit of the public network bandwidth utilization is 25%, the current public network bandwidth utilization is 20%, and the duration of the state that the public network bandwidth utilization is lower than 25% exceeds 3600s, it is determined that the bandwidth down-regulation triggering condition is met, and the bandwidth down-regulation mechanism is triggered.
In step S240, in the case where it is determined that the bandwidth adjustment triggering condition is satisfied, the bandwidth is adjusted accordingly according to the bandwidth adjustment policy.
In the present exemplary embodiment, referring to fig. 4, the adjustment of the bandwidth according to the bandwidth adjustment policy is implemented through steps S410 to S420.
In step S410, a bandwidth adjustment manner is determined, which includes increasing and decreasing. In the present exemplary embodiment, the bandwidth is adjusted in an increasing or decreasing manner according to the type of bandwidth adjustment triggered. The bandwidth adjustment mode can be to directly increase or decrease a fixed value or a fixed proportion; but also can be stepped up or stepped down. For example, the bandwidth is adjusted to the target bandwidth in two or three times, wherein the bandwidth adjustment amounts of the adjacent two times may be the same or different. In addition, bandwidth adjustment may be performed according to a set time, that is, the current bandwidth upper limit may be adjusted to the target bandwidth within a set time. The present exemplary embodiment is not particularly limited to a specific bandwidth adjustment manner.
In step S420, the original bandwidth upper limit is increased or reduced according to the bandwidth adjustment base and the bandwidth adjustment manner, so as to obtain an adjusted bandwidth. In this example embodiment, the bandwidth adjustment base may be flexibly set according to traffic, for example, the bandwidth adjustment base may be set as a percentage of the bandwidth adjustment base. Preferably, the bandwidth adjustment radix percentage may be set to 10% -30%. The bandwidth adjustment base may also be set to a fixed value or a range of values. When the bandwidth adjustment base is a range of values, a value may be randomly selected from the range of values as the bandwidth adjustment value, or the upper limit and the lower limit of the range of values may be correlated to obtain the bandwidth adjustment value, for example, an average value of the upper limit and the lower limit may be taken as the bandwidth adjustment value. And correspondingly adjusting the upper limit of the original bandwidth according to the bandwidth adjustment mode and the base number. The object of adjustment in this disclosure is the current upper bandwidth limit.
For example, as shown in fig. 5, assume that a user purchases a public network bandwidth IP of a company. The upper limit of the public network bandwidth is dynamically and custom adjusted according to the following steps S510-S580. In step S510, the user inputs user configuration parameters through the front-end interaction device, for example, a web service page with an interaction on the ECS management console of the cloud service. In step S520, the cloud backend server acquires the user configuration parameters. In step S530, the cloud monitoring server acquires a current instantaneous bandwidth. In step S540, the cloud monitoring server transmits the current instantaneous bandwidth. In step S550, the cloud backend server acquires an original bandwidth upper limit. In step S560, the cloud backend server calculates a current public network bandwidth utilization; for example, the current instantaneous bandwidth may be a percentage of the original bandwidth upper limit as the current public network bandwidth usage. In step S570, the cloud backend server determines whether a bandwidth adjustment triggering condition is currently satisfied; for example, if the public network bandwidth usage exceeds the corresponding user configuration parameter and the duration exceeds the first duration limit, it is determined that the bandwidth adjustment trigger condition is currently satisfied. Or the public network bandwidth utilization rate is lower than the corresponding user configuration parameter, and the duration exceeds the second duration limit, the current meeting of the bandwidth adjustment triggering condition is determined. In step S580, the cloud backend server adjusts the bandwidth accordingly according to the bandwidth adjustment policy. When the traffic suddenly changes, the user configuration parameters are redetermined and input, and multiple adjustments are not needed in general.
The user can configure parameters according to service demands, namely input bandwidth adjustment triggering conditions and bandwidth adjustment strategies, and the monitoring system obtains the current instantaneous bandwidth; the cloud server determines the current public network bandwidth utilization rate according to the received current instantaneous bandwidth and the original bandwidth upper limit; determining whether the received bandwidth adjustment triggering condition is met or not according to the current public network bandwidth utilization rate; and under the condition that the bandwidth adjustment triggering condition is met, correspondingly adjusting the bandwidth according to the received bandwidth adjustment strategy. On the one hand, when the service is suddenly increased, the bandwidth adjustment efficiency and the instantaneity can be improved, and meanwhile, the service loss such as lost data caused by bandwidth limitation can be avoided. On the other hand, when the service is less, the bandwidth is reduced, so that the resource waste is avoided, and the user cost is reduced. In addition, the manpower resources are saved, and the cost is further reduced.
The user configuration parameters of the present disclosure need to be set according to the self service condition and the service traffic bandwidth tolerance. After the one-time adjustment of the present disclosure is finished, when the traffic volume continuously increases and reaches the bandwidth adjustment triggering condition again, the adjusted bandwidth upper limit may be continuously adjusted until the traffic volume matches the bandwidth upper limit. After each bandwidth adjustment is completed, a period of silence (e.g., 5 s) may be set, during which no bandwidth adjustment is performed, to reserve sufficient reflection time for the system.
