Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, the technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
In the present embodiment, circulation storage organization is illustrated in fig. 1 shown below:
Wherein, buf is the data buffer area for recycling storage organization, i.e. circulation memory block pointer buf (pointer value)；
Write is circulation memory block write pointer write (integer value), indicates that current data writes circulation memory block pointer
The position of buf；
Read is circulation memory block read pointer read (integer value), indicates that current data reads circulation memory block pointer buf
Position；
MinSize is the minimized storage space (integer value) for recycling memory block；
CurSize is the current memory space (integer value) for recycling memory block；
MaxSize is the maximum memory space (integer value) for recycling memory block；
Total is the data word joint number (integer value) for recycling memory block current cache.
A kind of access method recycling storage organization provided in an embodiment of the present invention, referring to fig. 2, comprising:
S101: detection write-in and the data length for reading circulation storage organization；
S102: meet the first preset condition when data length is written or reads data length, then increase circulation storage organization
Memory space.
It is being embodied, is recycling the memory space and minimized storage space phase of the initial cycle memory block of storage organization
It together, and according to the memory space of initial cycle memory block is circulation memory block storage allocation, wherein buf is directed toward the memory of distribution
Space, write pointer write and read pointer read are directed to the initial position of circulation memory block, write=read=total=0.
Wherein, write operation, i.e. push, read operation, i.e. pop.
It should be noted that write-in and read operation are mutual exclusions, when write-in is carrying out, read operation will be waited；
When reading is carrying out, write operation will be waited.
The case where increasing in face of network flow, the data for the circulation storage organization for being written or reading are caused to increase, detection
Write-in and the data length for reading circulation storage organization, write-in or the data length increase read then, show increased flow capacity.When writing
Enter data length or read data length and meet the first preset condition, then increases the memory space of circulation storage organization.
In the specific implementation, the shared storage of data length that data length is written or reads data length and current cache is empty
Between be greater than the memory space of current circulation storage organization, then increase the memory space of circulation storage organization.Wherein, increase circulation
When the memory space of storage organization, current capacities are carried out double: CurSize=2*curSize, until CurSize >=
total.Space occupied by circulation storage organization after CurSize expression increase memory space.
It should be noted that for circulation memory block apply again expand after memory, original data copy to newly
Then memory headroom recycles old memory headroom.Write pointer and read pointer are directed toward new memory headroom initial position.If
CurSize > maxSize then reports an error.
Such as: write-in data length is length, when writing data into circulation memory block, recycles and caches in memory block
Data volume Total will become:
Total=total+length；
Wherein, total is the data word joint number for recycling memory block current cache.
Judge whether above-mentioned new Total is greater than curSize, if it is, showing that recycling memory block needs to increase storage
Otherwise space shows previous cycle memory block capacity adequacy, allow that data are written.
Further, further include following steps referring to Fig. 3 on above-mentioned practice processes:
S103: meet the second preset condition when data length is written or reads data length, then reduce circulation storage organization
Memory space.
In the specific implementation, the shared storage of data length that data length is written or reads data length and current cache is empty
Between be less than memory space with the previous cycle storage organization of presupposition multiple, then reduce the memory space of circulation storage organization.It needs
To illustrate that presupposition multiple is to be set according to when using according to use demand, wherein presupposition multiple is less than or equal to 1.
Such as: write-in data length is length, when writing data into circulation memory block, recycles and caches in memory block
Data volume Total will become:
Total=total+length；
Wherein, total is the data word joint number for recycling memory block current cache.
If minSize < curSize and Total < curSize/4, network flow decline is indicated, then, half-and-half reduce
Recycle the size of memory block, i.e. circulation memory block after CurSize=curSize/2, CurSize diminution.To recycle memory block
Again then the memory after application is reduced recycles old memory headroom original data copy to new memory headroom.Write finger
Needle and read pointer are directed toward new memory headroom initial position.
As can be seen from the above description, a kind of access method for recycling storage organization provided in an embodiment of the present invention, in sender
When quickly sending a large amount of TCP datas suddenly, which increases memory space, to collect data in time, realizes
When network flow is uprushed, more data packets are cached, reduce packet loss and the rate that reports an error.When to network flow decline, this is followed
The memory space adjustment of ring storage organization returns to suitable value, releases memory, improves the utilization rate of memory.
