Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The system architecture according to the embodiment of the present invention may include an internet server, an OLT (Optical line terminal), a plurality of ONUs (Optical Network units), and a plurality of subscribers. The user can communicate with the corresponding ONU, the ONU can communicate with the OLT, and the OLT can communicate with the Internet server. Fig. 1 is a schematic diagram of a system architecture according to an embodiment of the present invention, where the system architecture may include an internet server 101, an OLT102, an ONU1031, an ONU1032, an ONU1033, a user 1041, a user 1042, a user 1043, a user 1044, a user 1045, and a user 1046. User 1041 and user 1042 may communicate with ONU1031, user 1043 and user 1044 may communicate with ONU1032, user 1045 and user 1046 may communicate with ONU1033, ONU1031, ONU1032 and ONU1033 may communicate with OLT102, and OLT102 may communicate with internet server 101.
The user in the embodiment of the present invention may be a mobile device with a communication function, such as a smart phone, a tablet computer, and the like.
The embodiment of the invention installs the storage equipment on the existing OLT and adds the intelligent management function, so that the OLT can manage the data placed by a plurality of users, thereby realizing that the users accessed by the same OLT can read the files from the storage equipment of the OLT and saving the bandwidth of a backbone network. Correspondingly, the ONU is provided with storage access capability, and the actual storage position of the storage can be located locally on the ONU or stored on the OLT side storage device. Furthermore, when the network is idle, the OLT equipment directly accesses the files on the Internet through the backbone network and caches the files on the storage equipment of the OLT equipment, and when a user needs to access the files, the files are directly accessed through the ONU, so that better response speed is provided.
Specifically, in the embodiment of the present invention, the OLT adds a storage space, and in order to facilitate the query, the OLT allocates a corresponding storage space to each ONU that initiates the registration request message. Fig. 2 is a schematic diagram of a memory space of the corresponding OLT102 in fig. 1. ONU1031, ONU1032, and ONU1033 all initiate a registration request message to OLT102, where the registration request message carries identification information of each ONU. OLT102 allocates a first mark region corresponding to identification information of ONU1031 according to the received registration request message of ONU 1031; the OLT102 allocates a second label area corresponding to the identification information of the ONU1032 according to the received registration request message of the ONU 1032; the OLT102 allocates a third label area corresponding to the identification information of the ONU1033 according to the received registration request message of the ONU 1033.
Further, to better implement information sharing, a shared area is further provided in the storage space of the OLT, and the shared area corresponds to the identification information of ONU1031, ONU1032, and ONU 1033. The OLT's memory space may also include areas that have not been allocated.
In the embodiment of the present invention, the first mark area, the second mark area, the third mark area, and the shared area may have the same or different capacities, and the specific capacities may be automatically generated by the OLT, or may be configured by a person skilled in the art according to actual situations.
In the embodiment of the invention, the ONU is additionally provided with a resource space which is used for storing the identification information. Specifically, the process of ONU1031 establishing a resource space is described as an example. OLT102 allocates a corresponding first label area to ONU1031 according to the registration request message, and then returns a resource allocation message to ONU1031, and after receiving the resource allocation message, ONU1031 establishes a resource space corresponding to the first label area in OLT102, where the resource space is used to store identification information of files accessed by user 1041 and user 1042.
With reference to fig. 1, a detailed description is given below for each stage of initiating an access request by a user, and a process of establishing a correspondence between identification information stored in a resource space of an ONU and a file in a storage space of an OLT is specifically described.
(1) Stage one
This stage is an initial stage, that is, the resource space of the ONU has not stored the identification information, and the storage space of the OLT has not stored the file.
For example, user 1041 initiates a request message to ONU1031 that wants to access file a. After receiving the request message, ONU1031 queries the identification information stored in the resource space, and sends a second acquisition request message to OLT102 when determining that there is no identification information identical to the identification information of file a. After receiving the second acquisition request message, the OLT102 may query the entire storage space to determine whether a file corresponding to the identification information of the file a, that is, the file a, exists in the storage space; the storage space other than the first mark area corresponding to the identification information of ONU1031 may be inquired. At this time, if it is determined that file a does not exist in the storage space, OLT102 accesses internet server 101 via the network, acquires file a from internet server 101, stores file a in the first flag area corresponding to the identification information of ONU1031, and returns a request response message to ONU1031, where the request response message includes file a and may further include an instruction message. After receiving the request response message, ONU1031 sends file a in the request response message to user 1041, and stores the identification information of file a to the resource space of ONU1031 according to the indication information, thereby establishing the correspondence between the identification information in the resource space of ONU1031 and the file in the first identification region.
(2) Stage two
This stage is a stage in which the user accesses the file already stored in the storage space of the OLT on the basis of stage one.
After stage one, user 1041 initiates a request message to ONU1031 again, or user 1042 initiates a request message to ONU1031, and after receiving the request message, ONU1031 queries the identification information stored in the resource space, and sends a first acquisition request message to OLT102 when determining that the identification information identical to the identification information of file a exists. After receiving the first get request message, the OLT102 may query the entire storage space to determine whether the file a exists in the storage space. Preferably, OLT102 may query only the first flag area and the shared area corresponding to the identification information of ONU1031 according to the identification information of file a in the first acquisition request message, so as to effectively save the workload of query and improve the efficiency of acquiring file a. After acquiring file a from the first mark area, OLT102 returns a request response message to ONU1031, where the request response message may only include file a. After receiving the request response message, ONU1031 transmits file a to user 1041.
(3) Stage three
This stage is a stage in which the OLT stores the file in the shared area.
After the stage one or the stage two, the user 1043 or the user 1044 initiates a request message to the ONU1032, where the request message is received by the ONU1032, the identification information stored in the resource space is queried, and when it is determined that the identification information identical to the identification information of the file a does not exist, a second acquisition request message is sent to the OLT 102. After receiving the second obtaining request message, the OLT102 may query the entire storage space to determine whether the file a exists in the storage space. Preferably, since the file a does not exist in the second label region corresponding to the identification information of the ONU1032, to save the workload of the query, the OLT102 may query, according to the identification information of the file a in the second acquisition request message, only the storage space outside the second label region corresponding to the identification information of the ONU1032, and after the query, the OLT102 acquires the file a from the first label region and returns a request response message to the ONU1032, where the request response message includes the file a and may further include an indication message. After receiving the request response message, ONU1032 sends file a in the request response message to user 1043 or 1044, and stores the identification information of file a to the resource space of ONU1032 according to the indication information.
In the above process, OLT102 acquires file a from the first flag region corresponding to the identification information of ONU1031, where file a is a file that multiple users connected to ONU1031 and ONU1032 all access, and at this time, OLT102 may store file a from the first flag region to the shared region, so that after a request message for accessing file a is initiated by a user connected to ONU1032, OLT102 may directly query the storage region (including the second flag region and the shared region) corresponding to the identification information of ONU1032, and obtain file a. Further, the correspondence between the identification information in the resource space of the ONU1032 and the file in the shared area is established in the above manner.
(4) Stage four
After the third stage, the user 1045 or the user 1046 initiates a request message for accessing the file a to the ONU1033, and after receiving the request message, the ONU1033 queries the identification information stored in the resource space, and sends a second acquisition request message to the OLT102 when determining that the identification information identical to the identification information of the file a does not exist. After receiving the second obtaining request message, the OLT102 may query the entire storage space to determine whether the file a exists in the storage space. Preferably, the OLT102 may also query only the storage space outside the third label area corresponding to the identification information of the ONU1033, so as to save the workload of the query. After querying, after acquiring the file a from the shared area, the OLT102 sends a request response message to the ONU1033, where the request response message includes the file a and may further include an indication message. After receiving the request response message, ONU1033 sends file a in the request response message to user 1045 or 1046, and stores the identification information of file a to the resource space according to the indication information, and establishes a correspondence between the identification information in the resource space of ONU1033 and the file in the shared area.
Preferably, in order to ensure that the user can acquire the target file more quickly and more smoothly, each ONU may also store part of the initial content of the file corresponding to each identification information in the resource space of the ONU. Taking a video file as an example, assuming that the video file is 300M, the first 30M of the video file can be stored in the ONU, and the last 270M is stored in the storage space of the OLT, and after a user initiates a request message for accessing the video to the ONU, the ONU sends an acquisition request message to the OLT according to the request message, and sends the stored 30M video file to the user, so as to respond to the access request of the user more quickly. After the 270M video file sent by the OLT is obtained, the 270M video file is sent to the user, so that the user can watch the video smoothly, and the problem that the video watched by the user is not smooth due to low communication speed in the initial stage communication process is effectively solved.
The method for acquiring the target file provided by the embodiment of the invention at least relates to the communication process between the OLT, the ONU and the user, and the embodiment of the invention is introduced from the perspective of the OLT and the ONU respectively.
Fig. 3 is a schematic diagram of a method for acquiring a target file according to an embodiment of the present invention, where the method is based on an angle of an OLT, and specifically includes:
In step 301, in the embodiment of the present invention, the obtaining request message may be a first obtaining request message or a second obtaining request message, where the first obtaining request message and the second obtaining request message may be distinguished by setting different identifiers, for example, an identifier bit may be added to the obtaining request message, and the identifier bit may be set to 0 or 1, and it may be assumed that when the identifier bit is 0, the obtaining request message is the first obtaining request message, and when the identifier bit is 1, the obtaining request message is the second obtaining request message.
In step 302, the OLT determines, according to the type of the acquisition request message, an inquiry area in a storage space of the OLT, where the inquiry area is used to acquire the target file, and then acquires the target file from the inquiry area according to the identification information of the target file.
In the embodiment of the invention, the determined query areas are different if the distribution conditions of the storage space in the OLT are different. The query area determined by the OLT is described in two ways below.
The first method is as follows:
the OLT allocates corresponding marking areas for the ONUs according to the identification information of the ONUs, namely, each ONU registered on the OLT corresponds to one marking area.
Specifically, after receiving an acquisition request message sent by an ONU, an OLT determines that an inquiry area for acquiring the target file in a storage space of the OLT is a mark area corresponding to identification information of the ONU, when determining that the acquisition request message is a first acquisition request message by judging a value of an identification bit. After receiving an acquisition request message sent by an ONU, an OLT determines that an inquiry area for acquiring the target file in a storage space of the OLT is a storage space outside a mark area corresponding to identification information of the ONU under the condition that the acquisition request message is determined to be a second acquisition request message by judging the value of the identification bit.
The second method comprises the following steps:
the OLT allocates corresponding marking areas for the ONUs according to the identification information of the ONUs, namely, each ONU registered on the OLT corresponds to one marking area. And, the memory space of the OLT also comprises a shared area.
After receiving an acquisition request message sent by an ONU, an OLT determines that an inquiry area for acquiring the target file in a storage space of the OLT is a mark area and a shared area corresponding to identification information of the ONU under the condition that the acquisition request message is determined to be a first acquisition request message by judging the value of an identification bit. After receiving an acquisition request message sent by an ONU, the OLT determines that an inquiry area for acquiring the target file in a storage space of the OLT is a storage space outside a mark area corresponding to the identification information of the ONU under the condition that the acquisition request message is determined to be a second acquisition request message by judging the value of the identification bit.
In the embodiment of the invention, the ONU determines that the identification information of the target file is the same as the identification information stored in the resource space, which indicates that the target file is stored in the mark area and the shared area corresponding to the identification information of the ONU in the OLT, and at this time, the ONU sends a first acquisition request message to the OLT. The OLT queries the mark region and the shared region corresponding to the identification information of the ONU in a targeted manner according to the identification information in the first acquisition request message, so that the workload of querying can be effectively saved, and the efficiency of acquiring the target file is improved.
In the embodiment of the invention, the ONU determines that the identification information of the target file is different from the identification information stored in the resource space, and indicates that the target file is not stored in a mark area corresponding to the identification information of the ONU in the OLT, and at this time, the ONU sends a second acquisition request message to the OLT. The OLT queries the area outside the mark area corresponding to the identification information of the ONU in the storage space of the OLT in a targeted manner according to the identification information in the second acquisition request message, so that the workload of query can be saved, and the efficiency of acquiring the target file is improved.
In the embodiment of the present invention, when the acquisition request message is the second acquisition request message, if the OLT acquires the target file from a storage space other than the mark area corresponding to the identification information of the ONU, the target file is stored in the shared area from an area other than the storage area corresponding to the identification information of the ONU; or, if the OLT determines that the storage space other than the mark area corresponding to the identification information of the ONU does not include the target file, acquiring the target file through the network, and storing the target file in the mark area corresponding to the identification information of the ONU.
In step 303, the request response message sent by the OLT to the ONU may further include indication information, where the indication information is used to instruct the ONU to store the identification information of the target file in the resource space.
