Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The architecture of distributed data storage mainly includes: with a centered architecture and a non-centered architecture. For the Qos function with the central architecture, although the unified decision can be made on the whole, under the high concurrency service scene, the central node is easy to become a bottleneck, influences the service performance, has single-point fault risk and has limited lateral expansion capability. For Qos functions without a central architecture, the Qos functions are generally served in a single gateway manner, and when the Qos functions face unidirectional traffic bursts and other conditions, traffic imbalance is easy to occur, so that stability of service quality is poor. In order to solve the above problems, the present application provides a data processing method.
Referring to fig. 1, fig. 1 is one of flowcharts of a data processing method according to an embodiment of the present application, as shown in fig. 1, the method includes the following steps:
step 101, obtaining the uplink flow and the downlink flow of a target gateway in a plurality of gateways;
in this embodiment, a centerless architecture is adopted, so that when a plurality of gateways serve concurrently, the service performance is improved. The number of access users and service pressure of each gateway in the plurality of gateways can be continuously changed and uneven, the implementation of the Qos function can be in the gateway part of each node, and the Qos service of each node can comprise three functional modules: the system comprises a persistence module, a calculation distribution module and a flow control module, as shown in fig. 2 to 4.
The flow management and control module can adopt a Token-Bucket (Token-Bucket) mechanism to count and manage the flow. The flow management and control module is provided with a first token bucket (marked as a token bucket 1) and a second token bucket (marked as a token bucket 2), and after input/output requests sequentially acquire tokens in the token bucket 1 and tokens in the token bucket 2, subsequent processing can be performed. The service pressure of the target gateway is larger as the io request quantity of the target gateway is larger, the service pressure condition of the target gateway is acquired through the flow management and control module and reported to the persistence module, and the service pressure can comprise uplink flow and downlink flow.
The upstream traffic and the downstream traffic in different gateways are different, for example, a unidirectional traffic burst occurs in a target gateway in multiple gateways, that is, the difference between the upstream traffic and the downstream traffic is larger in a certain period, so that the upstream or downstream pressure of the traffic is further adjusted in step 102.
And 102, adjusting the number of uplink tokens and the number of downlink tokens in a first token bucket corresponding to the target gateway when the difference value between the uplink flow and the downlink flow is greater than or equal to a preset difference value, wherein the uplink tokens are used for controlling the uplink flow, and the downlink tokens are used for controlling the downlink flow.
The first token bucket corresponding to the target gateway is divided, so that the first token bucket is actually divided into two sub-parts of an uplink token and a downlink token, and the number of the uplink tokens and the number of the downlink tokens are equally divided in an initial state. Before the terminal sends a request to the server, the terminal needs to acquire an uplink token, the server returns the request to acquire a downlink token, namely, the uplink token controls uplink flow, and the downlink token controls downlink flow.
Considering the interference factors such as processing capacity of a client/server of the distributed data storage, retransmission of a transmission control protocol (Transmission Control Protocol, TCP) and the like, larger deviation of uplink traffic and downlink traffic of a target gateway in a certain period can be caused, namely, larger deviation of usage rates of an uplink token and a downlink token can be caused. And under the condition that the difference value is greater than or equal to a preset difference value, triggering a token balance mechanism to adjust the number of uplink tokens and the number of downlink tokens in a first token bucket corresponding to the target gateway, so that the number of the uplink tokens and the number of the downlink tokens in the first token bucket are in a stable difference value interval. Thereby alleviating the situation of unidirectional traffic bursts.
It should be understood that the target gateway is any gateway of a plurality of gateways, and other gateways of the plurality of gateways may have the same structure as the target gateway, which is not described herein.
In the embodiment of the invention, an uplink token is arranged in a first token bucket corresponding to a target gateway to control the uplink flow of the target gateway, a downlink token is arranged in the first token bucket corresponding to the target gateway to control the downlink flow of the target gateway, a token balance mechanism is triggered by detecting the uplink flow and the downlink flow of the target gateway, and the number of the uplink tokens and the number of the downlink tokens in the first token bucket are in a stable difference interval by adjusting the number of the uplink tokens and the number of the downlink tokens in the first token bucket under the condition that the difference between the uplink flow and the downlink flow of the target gateway is larger than or equal to a preset difference value, so that the situation of unidirectional flow burst is relieved, and the stability of service quality is improved. And the scheme without a central architecture is adopted, so that the performance requirement of multi-gateway concurrent service is met.
When the difference value between the uplink flow and the downlink flow is greater than or equal to the preset difference value, a token balancing mechanism is triggered, and the specific flow is as follows:
And dividing the first token bucket corresponding to each gateway in the plurality of gateways, taking a target gateway in the plurality of gateways as an example. Dividing a first token bucket corresponding to the target gateway, marking the token in the first token bucket in an equal division manner after updating each period, and marking an uplink token as T u The downstream token is marked T d . The first token bucket may be differentiated by a different color, for example, upstream tokens may be identified by yellow and downstream tokens may be identified by red.
And obtaining the uplink flow and the downlink flow of the target gateway so as to keep the difference value between the number of uplink tokens and the number of downlink tokens in the first token bucket in a stable difference value interval. It should be understood that, before the request (i.e. the uplink traffic) sent by the terminal to the server side is processed, the uplink token needs to be acquired, and the server side returns the request (i.e. the downlink traffic) to the terminal to acquire the downlink token, that is, the number of the uplink traffic corresponds to the number of the consumed uplink tokens, and the number of the downlink traffic corresponds to the number of the consumed downlink tokens. Thus, the difference between the upstream traffic and the downstream traffic can be characterized by the difference between the upstream token consumption number and the downstream token consumption number.
The conditions that trigger the token balancing mechanism may be set to be:. Wherein T is ru The number of uplink tokens in the first token bucket corresponding to the target gateway can be T rd The number of the downlink tokens in the first token bucket corresponding to the target gateway may be X% may be a preset value, for example, may be 30%, and the specific value may be adjusted according to the actual situation, which is not limited herein. In the initial state, T in the first token bucket rd And T is ru Equal and T rd And T is ru The sum is the Limit of the whole data catalogue total Is a number of (3). For example, limit total At 50 ten thousand, T in initial state rd Equal to T ru 25 ten thousand. As the io requests in the target gateway differ in the number of consumption of upstream and/or downstream tokens in the first token bucket, therefore T rd And T is ru An imbalance occurs between them. When the difference between the upstream flow and the downstream flow is greater than or equal to the preset difference, T rd And T is ru In the case of a difference of greater than or equal to the preset difference, i.e. +.>Under the condition of (1), adjusting the number of uplink tokens and the number of downlink tokens in a first token bucket corresponding to the target gateway so that T in the first token bucket rd And T is ru And the balance is achieved again, so that the situation of unidirectional traffic burst is relieved, and the stability of the service quality is improved.
It should be noted that, for other gateways in the multiple gateways, the dynamic adjustment of the uplink token number and the downlink token number in the corresponding first token bucket may be performed with reference to the target gateway to achieve the same technical effects, which is not described herein again.
Optionally, the adjusting the number of uplink tokens and the number of downlink tokens in the first token bucket corresponding to the target gateway when the difference between the uplink traffic and the downlink traffic is greater than or equal to a preset difference includes:
when the uplink flow is greater than the downlink flow and the difference between the uplink flow and the downlink flow is greater than or equal to a preset difference, determining the difference between the uplink flow and the downlink flow as a first difference;
and converting part of tokens in the downlink tokens into uplink tokens based on the first difference value.
In an embodiment, limit of the first token bucket corresponding to the target gateway is used total The number is 100 ten thousand as an example, and in the initial stateT rd And T is ru 50 ten thousand each. When the uplink traffic is greater than the downlink traffic in the target gateway, for example, the uplink traffic is 40 ten thousand and the downlink traffic is 10 ten thousand in a period, the number of consumed uplink tokens is 40 ten thousand, and the number of consumed downlink tokens is 10 ten thousand. Thus, the current upstream token holds (or: remains) a number T ru 10 ten thousand current downstream tokens hold number T rd 40 ten thousand. The preset value X% for setting the trigger token balance mechanism may be 30%. At this time T ru And T is rd The following are satisfied:. That is, the difference between the upstream flow and the downstream flow is greater than or equal to the preset difference, the upstream token conversion is triggered, and the difference between the upstream flow and the downstream flow (i.e. T ru And T is rd Is determined as a first difference, which in this example is: />。
And converting part of the tokens in the downlink tokens into uplink tokens based on the first difference value, so that the number of the uplink tokens and the number of the downlink tokens in the first token bucket reach balance again, thereby relieving the situation of unidirectional flow burst and improving the stability of service quality.
Optionally, a part of the downlink tokens are converted into uplink tokens, including at least one of the following:
transferring part of the tokens in the downlink token from the second area of the first token bucket to the first area of the first token bucket, wherein the first area of the first token bucket is used for storing uplink tokens, and the second area of the first token bucket is used for storing downlink tokens;
and converting the color of the tokens transferred to the first area in the downlink tokens from the second color into the first color, wherein the first color is used for identifying uplink tokens, and the second color is used for identifying downlink tokens.

In part downstream tokens (T d ) Up token (T) u ) In the conversion process of (2), the part (T) originally used for monitoring the downlink flow d Changing position in first token bucket, i.e. part T originally used for monitoring downstream traffic d Moving from the second area of the first token bucket to the first area of the first token bucket through the balancing channel and/or the portion T originally used for monitoring the downstream traffic d Changing the colour of tokens, i.e. the part T originally intended for monitoring downstream traffic d Converted from a second colour (e.g. red) to a first colour (e.g. yellow) so that this portion T d Changing to T for monitoring upstream traffic u 。
Wherein T is d Conversion to T u The number of (2) is:。
after the conversion of the downlink token to the uplink token part is completed, the number of the uplink tokens in the first token bucket corresponding to the target gateway is as follows: t'. ru =T ru +T rc1 10 ten thousand+15 ten thousand=25 ten thousand; after the conversion of the downlink token to the uplink token part is completed, the number of the downlink tokens in the first token bucket corresponding to the target gateway is as follows: t'. rd =T rd —T rc1 =40-15-25-ten thousand. Thus, after finishing the conversion from the downstream token to the upstream token, T 'in the first token bucket corresponding to the target gateway' ru And T' rd And the balance is achieved again, so that the situation of unidirectional traffic burst is relieved, and the stability of the service quality is improved.
Further, after each update, marking the tokens in the first token bucket in an equal division manner, so that: t'. ru =T’ rd =0.5×Limit total 。

and converting part of tokens in the uplink tokens into downlink tokens based on the second difference value.
In another embodiment, limit of the first token bucket corresponding to the target gateway is used total 100 ten thousand as an example, T in the initial state rd And T is ru 50 ten thousand each. When the uplink traffic is smaller than the downlink traffic in the target gateway, for example, the uplink traffic is 0 ten thousand and the downlink traffic is 50 ten thousand in a period, the number of consumed uplink tokens is 0 ten thousand and the number of consumed downlink tokens is 50 ten thousand. Thus, the current upstream token holds (or: remains) a number T ru 50 ten thousand current downstream tokens hold number T rd 0 ten thousand. The preset value X% for setting the trigger token balance mechanism may be 30%. At this time T ru And T is rd The following are satisfied:. That is, the difference between the upstream flow and the downstream flow is greater than or equal to the preset difference, the downstream token conversion action is triggered, and the difference between the upstream flow and the downstream flow (i.e. T ru And T is rd Is determined as a second difference, which in this example is: />。

Wherein T is u Conversion to T d The number of (2) is:。
after the conversion from the uplink token to the downlink token is completed, the number of the uplink tokens in the first token bucket corresponding to the target gateway is as follows: t'. ru =T ru —T rc2 =50-25-ten thousand; completing the uplink token downAfter the conversion of the token part, the number of the downlink tokens in the first token bucket corresponding to the target gateway is as follows: t'. rd =T rd +T rc2 =0ten thousand+25ten thousand=25ten thousand. Thus, after finishing the conversion from the downstream token to the upstream token, T 'in the first token bucket corresponding to the target gateway' ru And T' rd And the balance is achieved again, so that the situation of unidirectional traffic burst is relieved, and the stability of the service quality is improved.
Further, after each update, marking the tokens in the first token bucket in an equal division manner, so that: t'. ru =T’ rd =0.5×Limit total 。
In other implementations, limit of the first token bucket corresponding to the target gateway is used total 100 ten thousand as an example, T in the initial state rd And T is ru 50 ten thousand each. When the uplink traffic is smaller than the downlink traffic in the target gateway, for example, the uplink traffic is 0 ten thousand and the downlink traffic is 60 ten thousand in a period, the number of consumed uplink tokens is 0 ten thousand and the number of consumed downlink tokens is 50 ten thousand. At this time, for the part (10 ten thousand) exceeding 50 ten thousand in the downlink flow, the downlink token can be acquired in the next period, so as to reduce the situation of data packet loss and improve the stability of the service quality.
Optionally, after the adjusting the number of uplink tokens and the number of downlink tokens in the first token bucket corresponding to the target gateway, the method further includes:
and recording and storing the number of the adjusted uplink tokens and the number of the downlink tokens.
In one example, as shown in fig. 5, there is a hybrid deployment remote dictionary service (Remote Dictionary Serve, redis) database cluster in the server cluster, where the database contains a hash table named with each node identification number (Identity document, id). And each gateway takes 5s as a persistence period, updates the number of tokens consumed in a first token bucket of the last period of the flow management and control module in a hash table of the gateway id, and records and stores the number of adjusted uplink tokens and the number of adjusted downlink tokens in a value.
Optionally, after the adjusting the number of uplink tokens and the number of downlink tokens in the first token bucket corresponding to the target gateway, the method further includes:
determining the consumption quantity of the tokens in a first token bucket corresponding to the target gateway according to the adjusted quantity of the uplink tokens and the adjusted quantity of the downlink tokens, wherein the consumption quantity of the tokens comprises the consumption quantity of the uplink tokens and the consumption quantity of the downlink tokens;
and determining the token distribution quantity in the current period in a second token bucket corresponding to the target gateway according to the token consumption quantity in the first token bucket corresponding to the target gateway.
The determining the token distribution number in the current period in the second token bucket corresponding to the target gateway according to the token consumption number in the first token bucket corresponding to the target gateway comprises the following steps:
and determining the token distribution quantity in the current period in a second token bucket corresponding to the target gateway according to the consumption quantity of tokens in the first token bucket corresponding to the target gateway in the plurality of gateways, the sum of the consumption quantity of tokens in the first token bucket corresponding to each gateway in the plurality of gateways and the total quota of the whole data directory.
Specifically, determining the number of token allocation in the current period in the second token bucket corresponding to the target gateway can be determined according to the following formula:
。
wherein Qos i Allocating quantity, C1, of tokens in the current period in a second token bucket corresponding to the target gateway i For the consumption quantity of tokens in a first token bucket corresponding to a target gateway, limit total And (3) the total quota for the whole data directory, wherein n is the number of gateways, and n is a positive integer.
Therefore, by means of the design of the double token barrels, the actual service pressure is monitored, the management and control of gateway service quality are also realized, and the situations of gateway exit, new addition, unidirectional traffic burst and the like can be dealt with. The first token bucket can dynamically adjust the uplink and downlink flow pressure of the gateway and maintain flow balance; and calculating and dynamically adjusting the token distribution quantity in the second token bucket according to the service load condition of each gateway, thereby dynamically adjusting the service quality share of each gateway. And the stability of the service quality is improved. The gateways can be independently calculated, the influence of a certain gateway fault on other gateways is reduced, the concurrency calculation force of the cluster is strong, and the communication overhead is low.
In an embodiment, n gateways may be provided, and the Qos service of each gateway may include three functional modules: the system comprises a persistence module, a calculation distribution module and a flow control module.
Flow control module: and the statistics and the control of the flow are realized by a token bucket mechanism. And the service pressure information processing module is responsible for reporting the service pressure condition of the corresponding gateway to the persistence module, updating the number of tokens in the local token bucket according to the service pressure balancing result of the calculation distribution module aiming at the corresponding gateway, and further adjusting the service quality share of the gateway.
A persistence module: the server cluster is provided with a redis database cluster which is mixed and deployed, and the database comprises a hash table named by each node id.
The calculation and distribution module is used for: the function of the module is to directly update the token quantity Qos in the second token bucket in the target gateway flow management and control module after the specific weight calculation result of the target gateway access service in the whole system i As a result, persistence is not needed, and the data source is a hash table corresponding to the target gateway id of the persistence module.
In an example, the plurality of gateways includes a first gateway and a second gateway. The target gateway may be either one of the first gateway and the second gateway. Limit of first token bucket corresponding to target gateway total The number is 100 ten thousand as an example, and the T corresponding to the target gateway in the initial state rd And T is ru 50 ten thousand each. In other words, limit of the first token bucket corresponding to each gateway total The number can be 100 ten thousand, and the number of the T corresponding to each gateway in the initial state rd And T is ru 50 ten thousand each.
When the acquired flow of the first gateway is 60 ten thousand and the acquired flow of the second gateway is 100 ten thousand. The flow of the first gateway can comprise uplink flow and/or downlink flow, and a first token bucket in the first gateway can dynamically adjust the pressure of the uplink flow and the downlink flow corresponding to the first gateway to maintain flow balance; the flow of the second gateway can comprise uplink flow and/or downlink flow, and the first token bucket in the second gateway can dynamically adjust the pressure of the uplink flow and the downlink flow corresponding to the second gateway to maintain flow balance. The number of uplink tokens and the number of downlink tokens in the first token bucket are balanced through the conversion between the uplink tokens and the downlink tokens in the first token bucket, so that the situation of unidirectional traffic burst is relieved, the stability of service quality is improved, and the method is described in the above embodiment and is not repeated here.
After the number of uplink tokens and the number of downlink tokens in the first token bucket reach balance, a token supplementing operation can be performed on the token bucket 1 according to the period, so that the number of uplink tokens and the number of downlink tokens in the first token bucket reach the initial state number.
The second token bucket acts to govern the quality of service of the target gateway. The token number is updated according to the result of calculation of each period of the calculation distribution module. The sum of the number of tokens in the second token bucket of all the gateways is the Limit of the whole data directory total 。
And in the reporting period, the service conditions of the uplink token and the downlink token are summarized and reported to the calculation and distribution module. The calculation distribution module determines the consumption quantity of the tokens in the first token bucket corresponding to the target gateway according to the adjusted quantity of the uplink tokens and the adjusted quantity of the downlink tokens, wherein the consumption quantity of the tokens comprises the consumption quantity of the uplink tokens and the consumption quantity of the downlink tokens; for example, if the flow rate of the first gateway is 60 ten thousand and the flow rate of the second gateway is 100 ten thousand, the number of consumed tokens in the first token bucket corresponding to the first gateway is 60 ten thousand, and the number of consumed tokens in the first token bucket corresponding to the second gateway is 100 ten thousand.
The token distribution number in the current period in the second token bucket corresponding to the target gateway can be determined according to the token consumption number in the first token bucket corresponding to the target gateway. For example, the whole of the settingLimit Limit of data catalogue total The number of token allocation in the current period in the second token bucket corresponding to the first gateway is 100 ten thousand:
。
The number of token allocation in the current period in the second token bucket corresponding to the second gateway is as follows:
。
thus, the first token bucket can dynamically adjust the uplink and downlink flow pressure of the gateway and maintain flow balance; and calculating and dynamically adjusting the token distribution quantity in the second token bucket according to the service load condition of each gateway, thereby dynamically adjusting the service quality share of each gateway. And the stability of the service quality is improved.
For abnormal situations such as no traffic load, exit or joining of part of gateways, the execution result may be:
in one example, when traffic pressure of an individual gateway is zero or the cluster is exited due to a failure, the token assignment is set to 0 according to the calculation mode of the statistical distribution layer.
In one example, when a new gateway is added, reporting of token usage in the first token bucket reassigns a quality of service share to the gateway.
By the design of the double token barrels, the actual service pressure is monitored, the management and control of the gateway service quality are also realized, and the situations of gateway exit, new addition, unidirectional traffic burst and the like can be dealt with.
