It should be noted that the schematic diagram of a scenario of data transfer control system shown in FIG. 1 is only an example, this hair The data transfer control system and scene of bright embodiment description are the technologies in order to more clearly illustrate the embodiment of the present invention Scheme does not constitute the restriction for technical solution provided in an embodiment of the present invention, those of ordinary skill in the art it is found that with The differentiation of communication system and the appearance of new business scene, technical solution provided in an embodiment of the present invention ask similar technology Topic, it is equally applicable.

It is described in detail separately below.

In the present embodiment, it will be described from the angle of data transfer controller, data transfer controller tool Body can integrate in the network equipments such as server or gateway.

A kind of data transfer control method, comprising: obtain caching has used memory space；Storage has been used when caching When space is greater than preset threshold, the configured transmission of data transmission is obtained；Congestion control threshold is obtained according to configured transmission；Work as transmission When input delay in parameter is greater than congestion control threshold, the data of transmission are stored to slow according to the first default input speed It deposits.

Referring to Fig. 2, Fig. 2 is the flow diagram for the data transfer control method that first embodiment of the invention provides.It should Data transfer control method includes:

In step s101, obtain caching has used memory space.

In the present embodiment, data transfer controller mainly according to present data transmission the case where, dynamic carry out congestion control System.For example, acquisition caching has used the information such as memory space and configured transmission, dynamic carries out congestion control.Wherein, congestion Control can be used for adjusting data transmission in network amount, so that volume of transmitted data is approached the bearing capacity of current network, avoids internetworking Can decline, etc..

Optionally, in one embodiment, what data transfer controller acquisition cached can the step of having used memory space To include: the input request for receiving the carrying data that client is sent；Use storage empty according to input request caching Between.

Specifically, data transfer controller, which can be, receives the input request that client is sent, wherein input request In can carry data and solicited message of transmission in need etc., the data can be need be written caching data, the input Request may include write request or snapshot request etc..When data transfer controller receives input request, caching is obtained Used memory space, i.e. data transfer controller detecting caching use memory space, wherein the caching is data The preset caching of transmission control unit itself, for example, write buffer or snapshot caching etc., it only includes a storage which, which can be, Space also may include multiple memory spaces, and the size of multiple memory space can be consistent, can also be inconsistent.

Optionally, in another embodiment, data transfer controller obtains the step of having used memory space of caching May include: data transfer controller in real time or interval preset time obtain caching used memory space.Wherein, this is pre- If the time can carry out flexible setting according to the actual situation, specific value is not construed as limiting here.It is understood that caching The acquisition modes for having used memory space can also be acquisition otherwise.

In step s 102, when the transmission that caching is when having used memory space to be greater than preset threshold, and acquisition data are transmitted Parameter.

Get caching used memory space after, data transfer controller judgement caching use storage sky Between whether be greater than preset threshold, wherein preset threshold can carry out flexible setting according to actual needs, and specific value is here not It limits.For example, preset threshold can be set to the sky of the memory space 90% of caching when caching includes a memory space Between size；When caching includes the first memory space and the second memory space, preset threshold can be set to first depositing for caching Store up the space size, etc. in space.

When caching used memory space be less than or equal to preset threshold when, illustrate the non-congestion of current network, at this time The configured transmission that data transfer controller can remain current transmits data, for example, current input can be maintained Speed stores data to caching.When caching used memory space be greater than preset threshold when, illustrate that current network is relatively gathered around The step of plug, then data transfer controller can execute the configured transmission for obtaining data transmission.

Wherein, the configured transmission for obtaining data transmission can be, and obtain the number for needing that caching (being stored into caching) is written According to configured transmission, i.e., the data can be need be written caching data.The configured transmission may include write data into it is slow Input delay when depositing, input data time when writing data into caching, all input number of requests, the speed received increase Average delay etc. when the long factor and high speed writein, it is to be understood that the configured transmission can also include other parameters, Particular content is not construed as limiting here.

In step s 103, congestion control threshold is obtained according to configured transmission.

After obtaining configured transmission, data transfer controller can obtain congestion control threshold according to configured transmission, In certain embodiments, data transfer controller may include: according to the step of configured transmission acquisition congestion control threshold

The input data time is extracted from configured transmission, and all input number of requests received；According to input Data time and all input number of requests, calculate the average delay of input data；Congestion control door is calculated according to average delay Limit.

When caching is when having used memory space to be greater than preset threshold, data transfer controller triggers congestion control and calculates Method, wherein congestion avoidance algorithm is mainly used for, and obtains congestion control threshold according to configured transmission, and according to congestion control threshold Input speed is adjusted, stores data to caching according to input speed adjusted.Specifically, the configured transmission due to getting In include input data time and all input number of requests received etc. when writing data into caching, therefore, data pass Defeated control device can extract the input data time from configured transmission, and the institute received is extracted from configured transmission There is input number of requests, then, according to input data time and all input number of requests, calculates the mean time of input data Prolong, calculation formula is as follows:

Avg_delay=duration/write_total；

Wherein, avg_delay indicates that average delay, duration indicate the input data time, and write_total expression connects All input number of requests received.

Secondly, calculating congestion control threshold according to average delay, optionally, data transfer controller is according to average delay Calculate congestion control threshold the step of may include:

Obtain the calculation times of congestion control threshold；According to calculation times computing relay controlling elements；It is controlled according to delay The factor and average delay calculate congestion control threshold.Wherein, the calculation times of congestion control threshold are congestion avoidance algorithm touching The number of hair.Its calculation formula is as follows:

Write_thres=avg_delay* (1+ α)

α=exp (n, retreat_cnt)

Wherein, write_thres indicates that congestion control threshold, avg_delay indicate that average delay, α indicate delay control The factor, (i.e. statistics obtains the calculation times of retreat_cnt expression congestion control threshold from data transfer controller starting Congestion avoidance algorithm triggering number), exp indicate using natural constant e as the exponential function at bottom, n can with value be 1/4, or Person is other numerical value.

At this point, obtained congestion control threshold write_thres can be the approximation of the average speed of data transmission, with The number retreat_cnt of congestion avoidance algorithm triggering tend to be infinite, delay controlling elements α levels off to zero, it is meant that congestion The number retreat_cnt of control algolithm triggering is bigger, and the statistics of the configured transmission of historical data transmission is more accurate, so that congestion Control thresholding write_thres about levels off to the average value of statistics.

In step S104, when the input delay in configured transmission is greater than congestion control threshold, preset according to first defeated Enter speed to store the data of transmission to caching.

When caching is when having used memory space to be greater than preset threshold, congestion avoidance algorithm, at this time active client are triggered Input speed may be reduced to a very low velocity amplitude, for example, only receiving 3 or 4 inputs request etc. each second, i.e., Input delay write_delay can be a bigger value.

Since, including input delay, data transfer controller can be extracted from configured transmission in configured transmission Input delay, after obtaining congestion control threshold, data transfer controller may determine that whether input delay is greater than congestion control Thresholding processed illustrates that current network compares when input delay write_thres is greater than congestion control threshold write_thres Congestion starts slow growth algorithm, i.e., stores the data of transmission to caching according to the first default input speed, solve network and gather around In the case where plug or low speed, congestion is preferably avoided.

Wherein, input delay write_delay is the additional time delay of each input request, input delay write_ Delay is bigger, and the quantity for the input request that each second, data transfer controller received is fewer.Data transfer controller can Input speed is adjusted with adjusting the numerical value of input delay, to realize Congestion Avoidance.In addition, speed growth factor Write_inc is bigger, and input delay write_delay reduction is faster, and input speed is promoted faster.

It should be noted that it is a smaller value that speed growth factor write_inc, which can be set, so that when input Prolong write_delay slowly to reduce, data, which are stored to the input speed of caching, slowly to be increased.Optionally, the first default input Speed the comparison of the growth is gentle, achievees the effect that smooth, and rate curve can tend to straight line, can be by the first default input Speed is arranged so that input speed can just be write corresponding to full caching after preset time (such as 20 minutes or 30 minutes etc.) Speed；Or presupposition multiple (for example, 2 times or 3 times etc.) is set by the first default input speed and adjusts input in previous triggering The prefixed time interval of speed can just write speed corresponding to full caching, etc..Certainly, which can also To carry out flexible setting according to actual needs, specific value is not construed as limiting here.

In some embodiments, data transfer controller stores the data of transmission according to the first default input speed May include: to the step of caching

It obtains input and requests corresponding data；Calculate caching has used memory space within a preset period of time, reaches pre- If data transmission bauds needed for space size, the first default input speed is obtained；According to the first default input speed by data It stores to caching.

Specifically, the input that data transfer controller can be sent according to the client received is requested, and it is defeated to obtain this Enter to request corresponding data, and, caching is reached needed for pre-set space size using memory space within a preset period of time Data transmission bauds, wherein the preset time period and pre-set space size can carry out flexible setting according to actual needs, tool Body value is not construed as limiting here.For example, it may be what is cached after twenty minutes is just write using memory space needed for full caching institute Data transmission bauds.Then, which is set as the first default input speed, according to the first default input speed Degree stores data to caching, so as to make the utilization rate of caching keep stablizing, for example, remaining the utilization rate of caching 30%~80%, the concurrent quantity of network is effectively improved, the memory space of caching is taken full advantage of.

In some embodiments, data transfer controller according to configured transmission obtain congestion control threshold the step of it Afterwards, data transfer control method can also include:

It, will according to the second default input speed when the input delay in configured transmission is less than or equal to congestion control threshold Data are stored to caching, wherein the second default input speed is greater than the first default input speed.

Specifically, during being compared input delay with congestion control threshold, as input delay write_ When delay is less than or equal to congestion control threshold write_thres, illustrate current network not congestion, starting quickly increases at this time Long algorithm, into Fast growth phase.In Fast growth phase, data store the input speed to caching can be according to exponential type Increase, i.e., the second default input speed can be exponential type growth rate, can will count according to the second default input speed at this time According to storing to caching, therefore input delay write_delay can be rapidly achieved or be less than congestion control threshold Write_ thres。

In some embodiments, caching may include the first memory space and the second memory space etc., obtain caching After the step of having used memory space, data transfer control method can also include:

When the first memory space for taking caching using memory space of caching, presetting input speed according to third will Data are stored to the second memory space, wherein third presets input speed less than the first default input speed.

Specifically, caching may include one or more memory spaces, include that the first memory space and second is deposited with caching For storage space, wherein the first memory space is normal memory space, which can provide write-in number at any time According to the second memory space is emergency memory space, which is not written into data in the case where network non-congestion, only uses In the case where network congestion, occur providing write-in data when network disconnection.

Data transfer controller is in detecting caching during having used memory space, it can be determined that caching has made The first memory space of caching whether is taken with memory space, for example, vm_ when the first memory space of caching can be occupied full Buff_full is assigned a value of 1, and vm_buff_full is assigned a value of 0 when the first memory space of caching is not occupied full；Alternatively, can also Vm_buff_full is assigned a value of 0 when being occupied full with the first memory space that will be cached, and the first memory space of caching is not occupied Vm_buff_full is assigned a value of 1, etc. when full, for convenience, in embodiments of the present invention, will deposit with the first of caching Storage space, which is occupied full, is assigned a value of 1, the first memory space of caching is not occupied full for being assigned a value of 0 and is illustrated.

At this point, data transfer controller may determine that the value of vm_buff_full to determine that the first storage of caching is empty Between whether be occupied full, when the value of vm_buff_full be 1 when, illustrate caching take the first of caching using memory space Memory space, the slow service algorithm that opening network disconnects at this time enable the second memory space, while adjusting input speed, that is, press Input speed is preset according to third to store data to the second memory space.Wherein, third is preset input speed and be can be set to 1 second Clock inputs 1 time, either, according to information such as the size of the second memory space and the network ports, adjusts third and presets input speed It can guarantee that the second memory space is capable of providing storage service up to a few hours or a couple of days etc..Certainly, third presets input speed Flexible setting can be carried out according to actual needs, and specific value is not construed as limiting here.

From the foregoing, it will be observed that the embodiment of the present invention can use memory space by acquisition caching, whether to judge network Congestion, and (illustrate depositing for caching when memory space having been used to be greater than preset threshold when determining network congestion, such as when caching Storage space will be occupied full, and network compares congestion), start congestion avoidance algorithm at this time, obtains the configured transmission of data transmission, with And congestion control threshold is obtained according to configured transmission；Then, when the input delay in configured transmission is greater than congestion control threshold, Control input speed is increased slowly, stores the data of transmission to caching according to the first default input speed；To realize The purpose that network congestion is avoided to the input speed of caching is stored according to configured transmission adjust automatically data；The program can be with Guarantee the reliability of data transmission, and improves the efficiency of data transmission.

Citing, is described in further detail by the method according to described in above-described embodiment below.

For storing gateway, referring to Fig. 3, Fig. 3 is the system architecture diagram for storing gateway and carrying out data transmission control, In, storage gateway may include storage gateway module and storage gateway policy module etc., which may include depositing Gateway write buffer and storage gateway read buffer etc. are stored up, can also include storage gateway customer end module, storage in system architecture diagram Server-side command module, storage service end data module and final storage equipment etc..

Wherein, storage gateway customer end module is connectable to storage gateway module, mainly deposits with storage gateway module Storage gateway write buffer and storage gateway read buffer interact.

Storage gateway module, which can be, is deployed in storage equipment local, or is deployed in virtually depositing in the network environment of strange land It stores up in equipment.

Storing gateway write buffer is the local storage medium that can be accessed by storage gateway module, is written to for storing Gateway module is stored, but is not yet uploaded to the data of final storage EM equipment module.

Store gateway read buffer be the local storage medium that can be accessed by storage gateway module, for storage by The data that storage gateway module was read, or the data that storage is pre-read by storage gateway module.

Storage service sort command module is mainly used for, and to gateway module is stored, which can be used for controlling lower signaling The behavior of gateway module is stored, and receives the monitoring data that storage gateway module reports.

Storage service end data module can be deployed in final storage equipment local, for receiving storage gateway module transmission Data, and the data received landing is stored into EM equipment module to final.

Storage gateway policy module can be elementary tactics, local network conditions and network history transmission based on setting Situation etc., intelligent decision obtain the module of storage gateway module real-time Transmission rate.

Final storage EM equipment module may include the storage medium of one or more kinds of isomeries, be mainly used for storing data.

The present embodiment can pass through the input speed of balance storage gateway customer end module and the upload of storage gateway module Speed, so that storing gateway module under storage gateway write buffer and the lower situation of storage service end data intermodule bandwidth The input speed to storage gateway customer end module can be reduced automatically；In storage gateway module and storage service end data module Between bandwidth increase when, storage gateway module be capable of automatic lifting storage gateway customer end module input speed；In storage gateway When module and storage service end data intermodule are without network, storage gateway customer end module offer can be provided and serviced at a slow speed, Until network recovery, in network recovery, the input speed of storage gateway customer end module can be promoted rapidly, improves data The efficiency and reliability of transmission.

The data transmission stream journey to above system framework is illustrated below:

Firstly, storage gateway customer end module can initiate read request or write request to storage gateway module, net is stored It closes module and receives the read request or write request, when what is received is read request, storage gateway module is read according to storage gateway Whether caching hits, and decides whether to initiate read request or pre- read request to storage service end data module, i.e., when storage gateway is read When storing the data of reading in need in caching, storage gateway module can read data from storage gateway read buffer；Work as storage In gateway read buffer when the data of not stored reading in need, storage gateway module can initiate to read to storage service end data module Request or pre- read request, read data from storage service end data module according to read request or pre- read request.

When what is received is write request or snapshot request, the data write-in that storage gateway module will need to be written stores net Write buffer is closed, and the data are added in the asynchronous write request queue of storage gateway module, can be each by storage gateway module The version number that write request distribution is uniquely incremented by.

It stores gateway module and the read request received, asynchronous write request or snapshot request is sent to storage service end data Module, storage service end data module first trigger snapshot and generate calculation when receiving read request, asynchronous write request or snapshot request Method, records the network transmission situation (the including but not limited to configured transmissions such as transmitted data amount, propagation delay time) of the secondary request, and from Final storage EM equipment module reads data or writes data to final storage EM equipment module, completes the reading or write-in of data Afterwards, finally storage EM equipment module issues corresponding read request, asynchronous write to storage gateway module by storage service end data module Request or the response of snapshot request.

It stores gateway module upon receiving the response, records the network transmission situation of the secondary request and response.When receiving Be the response to read request when, storage gateway module will to storage gateway customer end module return read data, and by this Data are written in storage gateway read buffer according to cache policy.When what is received is the response to asynchronous write request, net is stored The write request in asynchronous write request queue will be handled according to cache policy by closing module.

The signalling process to above system framework is illustrated below:

When storage gateway policy module sends control signaling to storage service sort command module, storage service sort command mould Block issues control signaling to storage gateway module, after storage gateway module receives signaling, executes corresponding response according to the signaling Operation.

Below by above system framework caching situation and historic transmission situation data report flow into explanation:

Storing gateway module can be by local cache situation, history read request network transmission situation and history write request net The data such as network transmission situation are sent to storage service sort command module, and storage service sort command module protects the data received It deposits, which can judge that i.e. storage gateway policy module can be from storage for storage gateway policy module for dynamic strategy The data are obtained in server-side command module, and determine dynamic strategy according to the data.

It should be noted that the system architecture that storage gateway shown in Fig. 3 carries out data transmission control is only one and shows Example, system architecture and scene of description of the embodiment of the present invention etc. are the technologies in order to more clearly illustrate the embodiment of the present invention Scheme does not constitute the restriction for technical solution provided in an embodiment of the present invention, those of ordinary skill in the art it is found that with The differentiation of communication system and the appearance of new business scene, technical solution provided in an embodiment of the present invention ask similar technology Topic, it is equally applicable.

Referring to Fig. 4, Fig. 4 is the flow diagram of data transfer control method provided in an embodiment of the present invention.This method Process may include:

What S201, storage gateway detecting cached has used memory space；If caching has used memory space to be greater than first Preset threshold thens follow the steps S202；If caching has used memory space to be greater than the second preset threshold；It thens follow the steps S207。

Storage gateway can use memory space by storage gateway module detecting caching, wherein storage gateway mould Block can be in the input request for receiving client transmission, and that detects caching has used memory space；Either, net is stored It closes module and is also possible in real time or is spaced preset time, that detects caching has used memory space.

Data and solicited message of transmission in need etc. can be carried in input request, which, which can be, needs to be written The data of caching, input request may include write request or snapshot request etc., and it only includes one or more which, which can be, A memory space, the caching can be storage gateway write buffer.

Storage gateway is by storing after gateway module used memory space what is cached, to caching using depositing Storage space is judged, for example, caching can have been used memory space and the first preset threshold or the second preset threshold etc. Be compared, wherein the first preset threshold can less than the second preset threshold, first preset threshold and the second preset threshold Value can carry out flexible setting according to actual needs, and specific value is not construed as limiting here.

S202, storage gateway obtain the configured transmission of data.

When caching used memory space be less than or equal to the first preset threshold when, illustrate the non-congestion of current network, Storage gateway does not need adjustment input speed at this time, and current data can be maintained to transmit.

When caching is when having used memory space to be greater than the first preset threshold, illustrate currently stored gateway customer end module hair The input request sent is more, causes current network compared with congestion, at this point, storage gateway can be gathered around by storage gateway module starting Control algolithm is filled in, is obtained by congestion avoidance algorithm and the configured transmission for the data that caching is written is needed to adjust input speed.Example Such as, when caching used memory space be greater than memory space 90% space size when, obtain input delay, the visitor of client When the input data time at family end, all input number of requests of client, speed growth factor and gateway high speed writein The parameters such as average delay.

S203, storage gateway obtain congestion control threshold according to configured transmission.

After obtaining configured transmission, storage gateway can extract input number by storing gateway module from configured transmission According to the time, and all input number of requests received；According to input data time and all input number of requests, calculate defeated Enter the average delay of data；Its calculation formula is: average delay=input data time/all inputs number of requests.Then, root Congestion control threshold is calculated according to average delay, specifically, the number of congestion avoidance algorithm triggering is first obtained, further according to the number meter Delay controlling elements are calculated, its calculation formula is: delay controlling elements=exp (1/4, the number of congestion avoidance algorithm triggering)；Most Congestion control threshold is calculated according to delay controlling elements and average delay afterwards, its calculation formula is: congestion control threshold=average Time delay * (1+ postpones controlling elements).

S204, storage gateway judge whether the input delay in configured transmission is greater than congestion control threshold；If so, executing Step S205；If it is not, thening follow the steps S206.

Gateway is stored after obtaining congestion control threshold, input delay is compared with congestion control threshold, is judged defeated Enter whether time delay is greater than congestion control threshold.

S205, storage gateway store data to caching according to the first default input speed.

When input delay is greater than congestion control threshold, illustrate that current network compares congestion, i.e. storage gateway write buffer It is lower with storage service end data intermodule bandwidth, the slow growth algorithm of gateways and starting is stored, i.e., according to the first default input speed The data of transmission are stored to caching, optionally, the first default input speed the comparison of the growth is gentle, and rate curve can become In straight line, what the first default input speed can be arranged via to preset time period caching has used memory space, reaches Corresponding growth rate when to pre-set space size, for example, the first default input speed can be arranged so as to input speed Degree can just write speed corresponding to full caching after 20 minutes.It is understood that the first default input speed can basis Actual needs carries out flexible setting, and specific value is not construed as limiting here.By the way that input speed is adjusted to the first default input Speed can make the utilization rate of caching keep stablizing, take full advantage of the memory space of caching, effectively improve the concurrent of network Quantity.

For example, as shown in figure 5, carrying out data transmission the signal of control in Fig. 5 by congestion avoidance algorithm for storage gateway The input performance data that figure, as storage gateway pass through storage gateway module real-time detection client, wherein horizontal axis is the time, The longitudinal axis is the number that client (i.e. storage gateway customer end module) executes input operation within the unit time.It can from Fig. 5 Out, storage gateway maintain at the beginning quite high input performance (for example, the maintenance of storage gateway is quite high at from 0 to 6000 second Input performance), i.e., storage gateway module and storage service end data intermodule bandwidth it is higher, at this time promoted storage gateway customer The input speed of end module, until when the uploading speed of storage gateway can not meet the input demand of storage gateway customer end module (for example, from 6001 to 10001 seconds when network congestion occur), i.e. storage gateway write buffer and storage service end data intermodule band Width is lower, for example, input delay is greater than congestion control threshold, triggers congestion avoidance algorithm at this time, reduces to storage gateway customer The input speed of end module, by network jitter several times, congestion avoidance algorithm will store the input speed of gateway customer end module Being adjusted to a suitable value makes the defeated of client for example, current input speed is adjusted to the first default input speed The uploading speed for entering speed and storage gateway reaches dynamic equilibrium, even if the input speed and storage of storage gateway customer end module The uploading speed of gateway module reaches dynamic equilibrium (for example, reaching dynamic from input speed after 10001 seconds with uploading speed is deposited Balance) so that client input is able to maintain superior performance.It should be noted that between from 6001 to 10001 seconds, when depositing When storing up gateway module and storage service end data intermodule without network, storage gateway customer end module can be continuously and provided at a slow speed Some period of time in service, and the input speed for storing gateway customer end module is able to ascend in network recovery, improve data biography Defeated reliability.

S206, storage gateway store data to caching according to the second default input speed.

When input delay is less than or equal to congestion control threshold, illustrates the non-congestion of current network, store gateway at this time Start rapid growth algorithm, stores data to caching according to the second default input speed, for example, the second default input speed can To be the speed increased according to exponential type.It is understood that the second default input speed can carry out according to actual needs Flexible setting, specific value are not construed as limiting here.

For example, in Fig. 5, from 0 to 6000 second and after 10001 seconds, does not occur network congestion phenomenon, store gateway Module and storage service end data intermodule bandwidth are higher, at this point it is possible to increase input speed, for example, by current input speed Degree is adjusted to the second default input speed, to improve the utilization rate for the caching for storing gateway.

S207, storage gateway preset input speed according to third and store data to caching.

The caching (i.e. storage gateway write buffer) for storing gateway may include the first memory space and the second memory space etc., Wherein, the first memory space can provide write-in data at any time, and the second memory space is not written into the case where network non-congestion Data in the case where being only used for network congestion, occur providing write-in data when network disconnection.Memory space has been used when caching When greater than the second preset threshold, illustrate the phenomenon that network disconnection occur, which can be set to the first storage sky Between size illustrate to occur network disconnection that is, when the first memory space for taking caching using memory space of caching Phenomenon.At this point, the slow service algorithm that storage gateway opening network disconnects, enables the second memory space, while adjusting input speed, Input speed is preset according to third to store data to the second memory space of caching.Wherein, the default input speed of third can To be set as inputting for 1 second 1 time, either, third, which presets input speed, can guarantee that the second memory space is capable of providing storage Service is up to a few hours or a couple of days etc..It is understood that third presets input speed can carry out flexibly according to actual needs Setting, specific value are not construed as limiting here.

Since the second memory space is arranged, after network congestion occurs in storage gateway, storage gateway still is able to as visitor Family end provides high-speed service and continues for quite a long time；In the case that network is fully disconnected, local cache also can Low-rate service is enough switched to, it is unavailable without will cause storage service, it therefore, can be by fast for of short duration network congestion Speed, which retransmits, to be solved, then not will do it congestion control；For severe network environment, it can also guarantee the stabilization for storing gateway service Property.

In the embodiment of the present invention, based on the congestion avoidance algorithm of storage gateway, when network performance is good, to store gateway High-performance storage service is provided；In network congestion or low speed, the smooth input burr of client.Network condition badly very To suspension, storage gateway still is able to continue externally to provide storage service longer period of time.In the net of storage gateway When network performance boost, the input performance of client can be promoted rapidly to adapt to bandwidth promotion, and to store gateway local The utilization rate of caching keeps stablizing, and improves the upper transfer performance of storage gateway.I.e. storage gateway can occur for a long time in network When suspension, network low speed or network congestion, storage gateway can adjust automatically input speed so that client obtains Smoother and more stable storage service.In addition, the congestion avoidance algorithm of storage gateway is the adjust automatically based on network state, Intervene manually without user, it is very convenient.
