Identification information.
It is specifically introduced for each stage that user initiates access request with reference to Fig. 1, and specifically
Corresponding pass between the identification information stored in the resource space of bright ONU and the file in OLT memory spaces
System sets up process.
(1) stage one
This stage is identification information, and the OLT of being not yet stored with the resource space of starting stage, i.e. ONU
Memory space in also not yet store the documentary starting stage.
For example, user 1041 initiates the request message for desiring access to file a to ONU1031.ONU1031
After receiving request message, the identification information of storage in query resource space determines and does not exist with file a's
In the case of identification information identical identification information, second is sent to OLT102 and obtain request message.
After OLT102 receives the second acquisition request message, whole memory space can be inquired about, to determine
Whether there is the file corresponding with the identification information of file a, i.e. file a in memory space；Can also inquire about
Memory space beyond the first marked region corresponding with the identification information of ONU1031.Now, however, it is determined that
There is no file a in memory space, then OLT102 passes through network access Internet Server 101, from interconnection
After file a is got in network server 101, file a is stored in the identification information pair with ONU1031
The first marked region that answers, and request response is returned to ONU1031, wrap in the request response
File a is included, can also include indicating message.After ONU1031 receives request response, request is rung

This stage is that user accesses the file that stored in the memory space of OLT on the basis of the stage one
Stage.
After the stage one, the request that user 1041 initiates to desire access to file a to ONU1031 again disappears
Breath, or, user 1042 initiates the request message for desiring access to file a, ONU1031 to ONU1031
After receiving request message, the identification information of storage in query resource space determines the mark existed with file a
In the case of knowledge information identical identification information, first is sent to OLT102 and obtain request message.OLT102
After receiving the first acquisition request message, whole memory space can be inquired about, to determine memory space
In whether there is file a.Preferably, OLT102 can obtain the mark of the file a in request message according to first
Knowledge information, only inquires about the first marked region corresponding with the identification information of ONU1031 and shared region, from
And the workload of inquiry can be effectively saved, improve the efficiency for obtaining file a.OLT102 is from the first labelling
After region gets file a, request response is returned to ONU1031, now, the request response disappears
File a can only be included in breath.After ONU1031 receives request response, file a is sent to use
Family 1041.
(3) stage three
File is stored to the stage of shared region by this stage for OLT.
After stage one or stage two, user 1043 or user 1044 initiate to want to visit to ONU1032
The request message of file a is asked, after ONU1032 receives request message, storage in query resource space
Identification information, in the case of the identification information identical identification information that determination is not present with file a, to
OLT102 sends second and obtains request message.After OLT102 receives the second acquisition request message, can be right
Whole memory space is inquired about, and whether there is file a to determine in memory space.Preferably due to
There is no file a in the second marked region that the identification information of ONU1032 is corresponding, therefore, be to save inquiry
Workload, OLT102 can according to second obtain request message in file a identification information, only inquiry with
Memory space beyond second marked region corresponding to the identification information of ONU1032, through inquiry, OLT102
File a is got from the first marked region, and request response is returned to ONU1032, now, should
Request response includes file a, can also include indicating message.ONU1032 receives request response
After message, the file a in request response is sent to user 1043 or 1044, and according to instruction letter
Cease the resource space of the identification information storage of file a to ONU1032.
In said process, OLT102 is obtained from the first marked region corresponding with the identification information of ONU1031
File a is arrived, supporting paper a can be accessed per family by multiple the using that ONU1031 and ONU1032 connect
File, now, file a can be deposited to shared region by OLT102 from the first marked region such that it is able to
Realize that OLT102 can be direct after the user connected by ONU1032 initiates the request message for accessing file a
The inquiry memory area corresponding with the identification information of ONU1032 is (including the second marked region and shared region
Domain), file a is obtained, compared to the memory space beyond the second marked region of inquiry, can effectively be saved and be looked into
The workload of inquiry, improves the efficiency for obtaining file a.And, establish ONU1032 by the way
Resource space in identification information and shared region in file between corresponding relation.
(4) stage four
After the stage three, user 1045 or user 1046 initiate to desire access to file a to ONU1033
Request message, after ONU1033 receives request message, in query resource space store identification information,
In the case of determining the identification information identical identification information for not existing with file a, the is sent to OLT102
Two obtain request message.After OLT102 receives the second acquisition request message, can be to whole memory space
Inquired about, whether there is in memory space file a to be determined.Preferably, OLT102 only can also be inquired about
Memory space beyond the 3rd marked region corresponding with the identification information of ONU1033, to save inquiry
Workload.Through inquiry, OLT102 is got after file a from shared region, sends request to ONU1033
Response message, now, the request response includes file a, can also include indicating message.ONU1033
After receiving request response, the file a in request response is sent to user 1045 or 1046,
And according to configured information by the identification information storage of file a to resource space, it is established that the money of ONU1033
The corresponding relation between the file in identification information and shared region in source space.
Preferably, it is to ensure that user more rapidly, more swimmingly can obtain file destination, in each ONU
The part initial content of the file in its resource space corresponding to each identification information can also be stored.With video
As a example by file, it is assumed that the video file is 300M, then can store the front 30M of video file in ONU,
And rear 270M is stored in the memory space of OLT, when user initiates the request of access video to ONU
After message, ONU sends to OLT according to request message and obtains request message, and the 30M for being stored is regarded
Frequency file is sent to user, quickly to respond the access request of user.In the 270M for getting OLT transmissions
After video file, the 270M video files are sent to user, enable a user to swimmingly watch
Video, effectively prevent in starting stage communication process, cause user's viewing to regard as communication speed is slow
The problem that frequency has some setbacks.
The embodiment of the present invention provided acquisition file destination method in refer at least to OLT, ONU with
And the communication process between user, the embodiment of the present invention is carried out from the angle of OLT, ONU separately below
Introduce.
A kind of method schematic diagram of acquisition file destination that Fig. 3 is provided for the embodiment of the present invention one, the method base
In the angle of OLT, specifically include：
Step 301, OLT receive the acquisition request message that ONU sends；The acquisition request message includes
The identification information of the file destination；
Step 302, identification informations of the OLT according to the file destination, from the memory space of the OLT
Middle obtain the file destination；
Step 303, the OLT send request response to the ONU；The request response
Include the file destination.
The embodiment of the present invention, in step 301, it can be the first acquisition request message to obtain request message,
Can also be the second acquisition request message, wherein, the first acquisition request message and the second acquisition request message can
Made a distinction by arranging different marks, for example, a flag can be set up in request message is obtained,
Flag may be configured as 0 or 1, it will be assumed that when flag is 0, and it is that the first acquisition request disappears to obtain request message
Breath, when flag is 1, it is the second acquisition request message to obtain request message.
In step 302, according to the type for obtaining request message, OLT determines that the storage of the OLT is empty
Between in for obtaining the query region of the file destination, and then the identification information according to file destination, from institute
State.
In the embodiment of the present invention, the distribution condition of the memory space in OLT is different, it is determined that the interrogation zone for going out
Domain also differs.The query region that OLT is determined is introduced below by way of two ways.
