Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with attached drawing to the present invention
Each embodiment be explained in detail.However, it will be understood by those skilled in the art that in each embodiment party of the present invention
In formula, in order to make the reader understand this application better, many technical details are proposed.But even if without these technical details
And various changes and modifications based on the following respective embodiments, the application technical solution claimed also may be implemented.
The first embodiment of the present invention is related to a kind of methods of adjustment of nominal bandwidth.
The method of adjustment of nominal bandwidth in present embodiment can be applied to a kind of server, be specifically as follows CDN frame
Edge Server under structure (as accelerated cloud platform).It about existing Distributed Computer System, is operated by service provider
With " content distribution network " or " CDN " of management.Service provider typically represents the third using service provider base facility
Side (such as client) provides content delivery services.Such distributed system is typically referred to by one or more network linkings
Host computer set, and software, system, agreement and technology to be designed convenient for various services, such as content transmitting,
Web application accelerates or other support the source area infrastructure of outsourcing.CDN service provider usually pass through number attribute (such as
Website) service offering is provided, it is supplied in customer portals, is then deployed to network.
In present embodiment, individual server or server cluster are configured to service one group of client, several in client's group
The possible dynamic change of a client, each client itself may also dynamically adjust practical business, and due to different client traffic characteristics
It is different, for example some client's Hui Yuan ratios are big, the small number of request of some client files is high, and the big number of request of some client files is small.
Machine performance can be all influenced due to returning the factors such as source size, number of request size, leads to often there are some servers to be unable to run
To nominal bandwidth.And resource is when planning/use the type machine, it is also possible to which, due to business feature, desired bandwidth is high
In actual bandwidth, there is the not enough problem of the resource planned.
The process of the method for adjustment of nominal bandwidth is as shown in Figure 1, specific as follows in present embodiment:
Step 101, the communication that several clients that server to be adjusted is serviced adjust in the period at one is obtained to join
Number.
Specifically, client's number that server is serviced can be one, can be multiple a, service in practical application
Device may service a client more than ten simultaneously, and the resource of each customer plans distribution may be different.It is available in present embodiment
Bandwidth accounting meets the messaging parameter that the client of preset condition adjusts in the period at one in N number of client.For example, bandwidth accounting is arranged
Name first five client or bandwidth accounting be more than threshold value (such as 15%) client.Wherein, the resource of bandwidth accounting and planned assignment
It is positively correlated.The biggish client of resource accounting is often the user being affected to server actual bandwidth, and fetching portion resource accounts for
Bigger client can greatly reduce data acquisition amount, to reduce subsequent data amount of analysis, accelerate to determine the need for
Adjust the nominal bandwidth of server.
More specifically, messaging parameter can include at least following one: outflow bandwidth (that is: client bandwidth) OUT, inflow
Bandwidth (that is: returning upper layer bandwidth) IN, connection number K.Wherein, flow out bandwidth OUT and flow into bandwidth IN, between connection number K there is also
Correlation, specific as follows: OUT and K is positively correlated, and OUT=coefficient is positively correlated multiplied by K, IN and K, and IN=coefficient is multiplied by K.
Step 102, machine performance parameter of the server within the adjustment period is obtained.
Specifically, machine performance parameter can be denoted as M, be a comprehensive parameters, for example be to combine processor (i.e.
CPU), the parameter of memory and each hardware service condition, can be obtained by pressure test.More specifically, when obtaining, it can be with
According to the access time in a cycle, Access Success Rate, performance parameter MS when server is in performance bottleneck and place are obtained
Performance parameter M0 when communicating peak value.Wherein, performance bottleneck is server performance critical point, when reaching 80% such as CPU.
From the point of view of above-mentioned steps 101 and step 102, what step 101 obtained is the machine data of customer perspective, step 102
What is obtained is the machine data of server side.Specifically, an adjustment period can be one day, that is to say, that fortune daily
Row is primary to adjust.
Step 103, the bandwidth aggregate demand of several clients is determined according to the messaging parameter of client.
Specifically, the messaging parameter obtained in step 101 and machine performance parameter can be classified as following table, led to
Cross list and obtain with can be convenient the aggregate values of each column:
| Client | OUT | IN | K | M |
| A | ||||
| B | ||||
| C | ||||
| D | ||||
| E | ||||
| It amounts to |
Wherein, bandwidth aggregate demand refers to the aggregate values OUTALL of OUT column.
Step 104, available nominal bandwidth is estimated.
Specifically, this step estimates and is guaranteeing according to the messaging parameter of client and the machine performance parameter of server
Under the premise of server performance, it can be provided to the nominal bandwidth of several clients.
More specifically, server can not be or logical without limitation provision bandwidth, when client's request amount at a certain moment is too many
After traffic is too big, will result in the performance decline of server, and performance drops to certain value, it may cause shapes such as " crash "
State can not be offering customers service.So the available nominal bandwidth of server, must be actually that server is in still just
The state of informal dress business.
In present embodiment, this step can be specifically included:
(1) according to the messaging parameter of client and MS (server is in performance parameter when performance bottleneck), service is calculated
The nominal bandwidth Band1 that device provides within the adjustment period.
(2) according to the messaging parameter of client and M0 (server is in performance parameter when communication peak value), service is extrapolated
Nominal bandwidth Band2 of the device when each client is in communication peak value.
(3) it according to Band1 and Band2, determines under the premise of guaranteeing server performance, can be provided to N number of client's
Nominal bandwidth Band0.
Step 105, bandwidth aggregate demand and nominal bandwidth are compared, determines whether that adjusting server needs to service according to comparison result
Client.
Specifically, it is determined in the OUTALL and step 104 obtained in comparison step 103 in present embodiment
Band0 determines whether the client that adjustment server need to service according to comparison result.
More specifically, if OUTALL > Band0, it is determined that the client for servers' layout to be adjusted is excessive or industry
It is engaged in overweight, the resource of server is unable to satisfy the demand of these clients, so determining the client needed to adjust in client's group.Adjustment
Method, can be by the way of calling client away in practical application, can also be by the way of adjustment business, specifically can basis
Actual conditions are adjusted, and reduce server stress, are servers' layout more reasonable client or business.
On the other hand, if OUTALL < Band0, it is determined that the client for servers' layout to be adjusted is insufficient or suitable,
At least without calling client away, wherein it is specifically identified as insufficient or suitable, needs the difference according to OUTALL and Band0, in conjunction with
Actual conditions are judged, if insufficient, can be increased client or be increased business, if appropriate, then without adjustment, maintain the statusquo
?.
It needs to continue to explain, in actually adjustment, if it is considered that the number of adjustment is reduced to the greatest extent, then can be right
When the comparison result of OUTALL and Band0 is considered, principle is considered in adjustment, and the Band0 for example estimated provides floating space, specifically
Say, can by estimate can provide bandwidth B and0 setting floating coefficient.More specifically, floating coefficient can for 0.8~
1.2, that is to say, that section is set by Band0, by taking the Band0 estimated is 1000M as an example, as long as then being in: 800M~
Between 1200M, the client for being recognized as servers' layout to be adjusted is appropriate, without being adjusted.
It is noted that the method for adjustment of the nominal bandwidth in present embodiment is applied to server, in practical application,
Also it can be applied to dedicated adjustment terminal, which connect with server communication to be adjusted, to obtain all kinds of parameters,
Whether the client that adjustment terminal is serviced according to all kinds of Parameter analysis servers later is suitable, and specific implementation process is no longer superfluous herein
It states.
As it can be seen that present embodiment determines bandwidth aggregate demand according to the historical data of client, while being estimated according to historical data
The available suitable nominal bandwidth of server itself, so that it is determined that server when for this N number of offering customers service, services energy
Whether power is enough, and whether nominal bandwidth is suitable.Particularly due to the machine performance ginseng of messaging parameter and server when active service
Based on number, convenient for embodying influence of the different clients different business to server performance, make as the nominal bandwidth for comparing basis
Estimation it is more practical accurate.As it can be seen that the method for adjustment of the nominal bandwidth in present embodiment can more accurately estimate clothes
Business device can provide bandwidth, preferably plan the client that can be serviced for server, while it is not of the same trade or business to be suitable for service different clients
The situation of business, wide adaptability, generalization are good.In addition, in the present embodiment, obtaining customer data can only fetching portion resource
The biggish client of accounting can greatly reduce data acquisition amount and amount of analysis under the premise of guaranteeing to adjust accuracy, thus plus
It regulates the speed fastly.
Second embodiment of the present invention is related to a kind of method of adjustment of nominal bandwidth.Specify a kind of specific normal band
Wide method of adjustment is obtaining client in a messaging parameter adjusted in the period in present embodiment, is mainly obtaining client
The peak value of the messaging parameter in the period is adjusted at one.
The method of adjustment of nominal bandwidth in present embodiment is as shown in Fig. 2, by taking a cycle is one day as an example, specifically
It is bright as follows:
Step 201, the communication that several clients that server to be adjusted is serviced adjust in the period at one is obtained to join
Several peak values.
When specifically, due to communication peak value, the pressure of server is maximum, and it is maximum extreme that Analysis server is in pressure
The data of situation are conducive to understand server in the performance of extreme case, while can greatly reduce the acquisition of data volume.
More specifically, bur facture can be used to exclude the influence of bur in cycle peak data acquisition,
Such as: 8 minute datas (with a data instance per minute) around centered on target point removes the value of object pixel itself,
With the value of the average value of 8 minute datas around replacement target point, the value of replaced target point is exactly bur treated peak
Value.
It can be found that when obtaining outflow bandwidth OUT, flowing into bandwidth IN or connection number K bur can be removed using above-mentioned
Facture treated peak value.
In present embodiment, step 202 to step 205 is similar to step 105 with step 102 in first embodiment,
Details are not described herein.
As it can be seen that the data obtained in the method for adjustment of nominal bandwidth in present embodiment specifically obtained is peak value, and can
To be bur treated peak value, so that convenient for getting the communication pressure maximum period, to be conducive to the normal band of estimation
Wide availability, moreover it is possible to the influence of bur is excluded, so that the parameter values got more meet reality.

Wide method of adjustment, specific, concrete reduce server when needing to adjust the client that server need to service, by calling client away
Pressure, and preferentially call the client bigger to the bandwidth contributions of server away.
Specifically, N number of client is being obtained respectively in a peak value for adjusting the messaging parameter in the period, obtaining respectively
The messaging parameter of client is in machine performance parameter when peak value；According to the machine performance parameter of several clients and communication ginseng
Several and server machine performance parameter, determines influence of each client to the bandwidth of server；It is according to comparison result determination
The client that no adjustment server need to service, having includes: preferentially to call away when adjusting the client that server need to service to server
The bigger client of bandwidth contributions.
It wherein, can be according to the outflow flow OUT of each client when determining influence of each client to the bandwidth of server
The machine performance parameter M of accounting and each client in the outflow flow summation OUTALL of all clients, obtains each client
Influence to server performance.Such as: influence of the A client to server performance can use following formula: MA* (OUTA/
OUTALL)。
Wherein, MA is machine performance parameter when A client is in communication peak value, when OUTA is that A client is in communication peak value
Outflow flow, OUTALL is respectively at the sum of outflow flow when communication peak value for server institute to be adjusted services client.
When needing to call client away, the principle for being sized to call away client can be will affect, it is bigger such as preferentially to call influence away
Client.
As it can be seen that present embodiments provide for a kind of adjustment sides for preferentially calling the client bigger on server bandwidth influence away
