Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated.
As shown in Figure 1, in the method in client net control bandwidth of the present invention and device embodiment, its method comprises:
Step S11 obtains band data: in the present embodiment, band data illustrates the band data of this client, specifically, being exactly that the network that each time period of this client within a period of time should use connects bandwidth, is that manager is arranged or requirement the bandwidth of this client.Due in the present embodiment, by network and multiple client's side link, for each client, can all there is such a band data (namely band data) in a server; Certainly, as the case may be, the band data of above-mentioned each client can be identical, also can be not identical; And specific to a band data, content wherein also can be arranged by manager in advance; If using the above-mentioned band data for a client as a subset, the multiple band data combinations respectively for multiple client obtain a set; In the present embodiment, above-mentioned set is stored in the server, and when any one the client game server be connected by network with server, server, according to the address of the client logged in, finds corresponding subset, and sends it to client.Like this, client just achieves the band data of himself.Certainly, in some cases, obtaining of band data may not be like this, such as, can be obtained by other mode by manager and import in above-mentioned client.Although such operation also can realize the control to different clients, specific due to remote data transmission, can bring some inconvenience.In the present embodiment, band data has formulated the maximum bandwidth (check strap width values) that a client is allowed to by a time origin when this client on all time points in a setting-up time is connected with server, such as by a time origin to one week or intraday free bandwidth value; For the band data for a client, that includes by a time origin to setting-up time time period divide and described each time period in this client be allowed to maximum bandwidth value connected to the network, there is a bandwidth value each time period, these bandwidth values can be identical, also can be different; But all can arrange respectively; Equally, the length of each time period also can be identical or different, but its initial time and end time also can be arranged individually, respectively; In the present embodiment, the above-mentioned time period covers by all regions of time origin to setting-up time.In this step, obtain the band data for this client by said method exactly, and be stored in above-mentioned client.It is worth mentioning that, when starting or band data upgrades, just performing step S11; Once band data obtains and do not upgrade, such as, when again starting to judge whether current bandwidth value exceeds limiting bandwidth after waiting for setting-up time, will directly perform by step S12.In like manner, if band data on server upgrades, server will notify each client, and distribution bandwidth data again, in this case, step S11 is shown in and can be again performed.
Step S12 obtains current time, and judge the time period residing for current time, obtain check strap width values: because client has obtained above-mentioned band data, in this step, client obtains the current time on himself, and this time is exactly the system time of client; After obtaining this time, client judges for current time, and which in each time period dividing out for basic point with above-mentioned time origin it is in; Once the time period residing for current time determine, just can by the maximum obtaining this client current network bandwidth in above-mentioned band data.About how judging residing for current time the time period particularly in the present embodiment, referring to Fig. 2, also can be described after a while.
Step S13 obtains current bandwidth value: in this step, and client obtains its bandwidth connected to the network current speed of server exchange data (namely with), and this speed or bandwidth can be obtained by the data traffic on Sampling network interface.
Does is step S14 current bandwidth value greater than check strap width values? in this way, perform step S15, otherwise, perform step S16; In this step, two bandwidth values obtained in different step relatively above, and judge whether the actual bandwidth value carrying out network connection or exchanges data of client is greater than the maximum bandwidth value that the period residing for current time allows, as being greater than, then perform step S15, regulate actual bandwidth value to make it be not greater than or equal to the maximum bandwidth value of this period permission; As being not more than, then without accommodation zone width values, directly perform step S16.
Step S15 regulates current bandwidth value to be above-mentioned check strap width values: in this step, regulate actual bandwidth value, namely limit the network connection speed of this client, makes it be unlikely to take too much bandwidth and causes the access of other clients difficult.It is worth mentioning that, after performing this step, will step S16 be performed.
Step S16 waits for setting-up time: because above-mentioned deterministic process needs constantly to carry out during client's side link network, to ensure that the network bandwidth of client is unlikely to bring impact to other clients; But, if ceaselessly carry out above-mentioned judgement always, bring larger burden can to the processor of client; So both met the monitoring to bandwidth, when taking into account again the burden reducing client end processor, in the present embodiment, client will wait for a period of time, then start deterministic process next time.This stand-by period is setting in advance; In the present embodiment, normally 1-10 second.
For the present embodiment, above-mentioned current time obtain and the determining step of residing time period concrete as shown in Figure 2, it comprises:
Does is step S21 current time greater than slot start time? in this way, next step is performed; Otherwise, jump to step S24; In this step, be first the data of taking out a time period in above-mentioned band data, these data just include initial time and the end time of this time period; In the present embodiment, if perform this step first, then by first time period of above-mentioned band data, if not performing this step first, then obtained the data of next time period backward by the time period order obtaining data last time.
Does is step S22 current time less than end time period? in this way, perform step S23, otherwise, jump to step S24 and perform; In this step, if judge that current time is greater than the initial time of a time period and is less than its end time, then can assert that this current time was just in this time period.
Step S23 obtains this period and limits bandwidth returning: in this step, because current time was in this time period, so, change the maximum Permissible bandwidth value that maximum bandwidth value corresponding to time period is exactly current connection, this value is taken out and returns.
The all period traversals of step S24? in this way, step S26 is performed; Otherwise, perform step S25.
Step S25 obtains subsequent period data: when still having that the period, (time period) did not compare with current time (period does not travel through), owing to having been judged current time by above-mentioned steps S21-22 not within the time period relatively crossed, so, need the data of taking out a time period again to compare with current time; In this step, the next time period data after the time period of having compared before taking-up, and return step S21, this next one time period and current time are compared.
Step S26 obtains default bandwidth and returns: in this step, because in traversal band data, all time periods are the time period found residing for current time, so use the maximum bandwidth value that the default bandwidth of this band data allows as current time.It is to occur by time origin to setting-up time that this situation does not intactly cover whole in the time period of above-mentioned band data, and this is also the method for the complexity of a kind of setting data amount reducing band data or the setting reducing band data.In addition, in order to reduce complexity that band data arranges or reduce the time or expense that judge that time period residing for current time is used, in the present embodiment, all right setting example outer period in band data, the exception period is to the Netowrk tape width values that should have the exception period; When judging the period residing for current time, first judging whether current time is in the exception period, as current time is in the exception period, then directly returning the Netowrk tape width values of described exception period, no longer carrying out the judgement of above-mentioned steps S21-26; As current time is not in the exception period, then carry out the judgement of above-mentioned steps S21-S26 again.Although many steps relatively time, in many cases, the exception period the judgement that client can be made no longer to carry out step S21-S26 is set, dramatically saves on judgement time and the consumption of time period residing for current time.
The invention still further relates to a kind of device realizing said method, its structural representation as shown in Figure 2, comprises band data memory cell 1, current time obtains and judging unit 2, current check strap width values acquisition unit 3, current bandwidth obtains and regulon 4, stand-by period unit 5 and band data acquisition unit 6; Wherein, band data memory cell 1 is for storing the band data obtained with time origin, and this band data comprises and dividing and the check strap width values of this client in above-mentioned each time period to the time period of setting-up time by time origin; Current time obtain and judging unit 2 for obtaining current time, and determine that current time is in the time period by time origin; Current check strap width values acquisition unit 3, for according to the time period residing for current time, obtains the check strap width values of this time period; Current bandwidth obtain and regulon 4 for obtaining active client Netowrk tape width values, and judge whether it is greater than the above-mentioned check strap width values obtained, in this way, make described current network bandwidth value equal present period check strap width values; Stand-by period unit 5 is for regulating or waiting for after not regulating current bandwidth that setting-up time enters once bandwidth adjustment again; Band data acquisition unit 6 logs in connected server for making client, reception server timing or sporadically send and store on that server, corresponding with this client address band data.It is worth mentioning that, in the present embodiment, the setting of band data also completes on above-mentioned server; User also can recall above-mentioned band data and on the server after amendment stored in, amended band data is sent to client by the timing of this server or not timing.
As shown in Figure 4, in the present embodiment, current time obtains and judging unit 2 comprises initial time judge module 21 further, end time judge module 22, the current slot network bandwidth obtain module 23, time period Ergodic judgement module 24, default bandwidth value obtain module 25 and exception period judge module 26; Wherein initial time judge module 21 is for judging whether current time is greater than the initial time that obtains the time period of its data; End time judge module 22 is for judging whether current time is less than the end time of described time period; The current slot network bandwidth obtains module 23 for reading the bandwidth value of described time period and returning; Time period Ergodic judgement module 24 for judging in band data, whether all time periods compare all, and obtains future time segment data when not traveling through the described time period; Default bandwidth value obtains module 25 for not being read and return default bandwidth value in any one time period in described band data in current time; Exception period judge module 26, for judging whether current time is in the exception period, in this way, returns the Netowrk tape width values of described exception period.
In a word, in the present embodiment, first, in service end, band data setting is carried out to each client.According to the practical business situation of each bar circuit of each user, each client can use oneself privately owned band data also can use the band data of system default, a series of speed limits (i.e. check strap width values) that band data was divided into groups by temporally (such as week) are formed, user can the speed limit of specific definition random time section in a day, for the configuration simplifying band data adds acquiescence speed limit, exception speed limit two configuration items, wherein give tacit consent to speed limit for determining the velocity amplitude of all non-fixed time sections in circuit strategy; Exception speed limit is used for exception, and it has the priority than common speed limit Xiang Genggao.After client terminal start-up, logon server, obtains the up-to-date band data of this user from service end after having verified.
The velocity amplitude that client obtains current time point with the interval of 1 second from band data (encapsulates band data, a time origin is set, return the speed limit of this time point in band data), afterwards with the speed limit interface in current speed limit calling communication assembly, speed limit is carried out to network, makes it be not more than limiting bandwidth.After the band data of service end changes, server initiatively sends new band data to current online client, and client uses the new band data received to substitute old execution speed limit behavior.
