Software, including online games, is growing in file size. Conventionally, in order to receive a file online, users have downloaded the file by directly connecting to a download server that supplies the file. However, if the file is large and many users use the file (for example, the installation file of an online game), the user directly connects to the download server and receives the file. As a result, side effects such as the server stopping its operation have occurred.

Peer to Peer (P2P) communication has recently been introduced to reduce the traffic load on the server. P2P communication receives a plurality of blocks that make up a file separately from users who have files they want to receive among users connected through the network, increasing communication speed and causing users to download servers This is how you can prevent it.

Hereinafter, a method and apparatus for controlling file download network distribution according to each embodiment of the present invention will be described with reference to the accompanying drawings.

In the following description, in order to clarify the understanding of the present invention, description of well-known technology for the features of the present invention will be omitted. The following embodiments are detailed description to help understand the present invention, and it should be understood that the present invention is not intended to limit the scope of the present invention. Therefore, equivalent inventions that perform the same functions as the present invention will also fall within the scope of the present invention.

In the following description, the same identification symbol means the same configuration, and unnecessary redundant description will be omitted.

In addition, in the following description, the file refers to all data that can be downloaded by the user terminal through peer-to-peer (P2P) communication and other network connections. In particular, it basically means a file to download using P2P communication. For example, a game program file downloaded through a game execution client and installed in a user terminal and a patch file thereof for execution of an online game.

Indeed, many online game execution files have been downloaded directly by accessing a download server that stores files. However, as the capacity increases, a technique of downloading a file using P2P communication has recently been applied.

Further, in addition to the online game execution file, all files that can be downloaded using the P2P communication method that downloads the blocks constituting the file from other user terminals, such as other general program files and media files, may belong to the file of the present invention. It will be obvious to those skilled in the art.

In the embodiments of the present invention, " communication ", " communication network ", and " network " The three terms refer to wired and wireless local area and wide area data transmission and reception networks capable of transmitting and receiving a file between a user terminal, a terminal of another user, and a download server.

1 is a flowchart of a file download network distribution control method according to an embodiment of the present invention.

In the file download network distribution control method according to an embodiment of the present invention, first, loading a network distribution table determining a ratio between a download amount using a connection with a download server network and a download amount using a P2P network (S1) ) Is performed.

As described above, the network distribution table loaded in step S1 means a database in which the ratio of download amount through two network connections to a file is determined.

As mentioned above, the file in the present invention is composed of a plurality of unit blocks having a unit size, and in the present invention, basically, some of the blocks constituting the file are downloaded through a connection with a download server network. Received from the server, the remaining blocks are received from the terminal of other users using the P2P network.

Therefore, the download amount through the connection with the download server network and the download amount using the P2P network mean the number of blocks downloaded through each network. That is, in the present invention, the ratio of the download amount through the connection of two networks will be understood as the ratio of the number of blocks downloaded through the connection of two networks.

There may be a plurality of ratios defined in the network distribution table, and the ratio of the number of blocks to be downloaded through the download server network and the P2P network changes dynamically by selecting the ratio according to each situation in the overall flow of the present invention.

In the present invention, the ratio determined for the network distribution table has a certain rule. For example, as the network traffic of the download server increases, the ratio of the download amount using the P2P network is set to increase. When the network traffic of the download server is increased, if the download rate is continuously connected to the download server network, the download server network may be overloaded, thereby slowing down the transmission and reception of data from the download server.

In addition, as the number of users connected to the P2P network increases, the ratio of the download amount using the P2P network may be set to increase. If the number of users connected to the P2P network is large, increasing the percentage of downloads using the P2P network will not cause any problem in the download speed, and it is possible to prevent the overload by reducing the traffic of the download server network as much as possible.

In addition, in the network distribution table, another table may be loaded according to the type of file.

When a file is downloaded to a user's terminal through either a direct connection to a P2P network or a server network, it is divided into a plurality of blocks and downloaded as mentioned above. At this time, the unit size of the plurality of blocks is different depending on the type of the file and the settings of the file producer, the communication company and the like. For example, a file having a unit size of 32 kilobytes (KB) and a file having 64 KB may exist.

Therefore, different ratios may be set according to the unit size of each file, and thus different network distribution tables should be loaded according to the type according to the unit size of each file. .

An example of a network distribution table related to this will be described in more detail with reference to FIGS. 8 and 9.

In step S1, the network distribution table is loaded to prepare for selecting a ratio to be applied to the user terminal through a later step.

After step S1, step S2 of selecting network history data for each time zone of the download target file of the download server is performed. The step S2 may be a step of loading network history data, which is the traffic of the download server network or the number of P2P network access users, according to one periodic period.

The network history data is preferably data obtained by accumulating traffic information of the download server network or data of the number of users connected to the P2P network at regular time intervals (e.g., every three hours). For example, the average value of continuously measuring traffic values of the download server network for each time period may be included in the network history data, or the average number of users accessing the P2P network for a file may be included in the network history data.

The average value of the traffic values of the download server network may be expressed as a percentage value with respect to the maximum available traffic value of the download server network.

When the step S2 is completed, a step (S3) of selecting a ratio matching this for each section divided by one period is performed. That is, the network distribution ratio matching the network history data in the current time zone is selected.

In the present invention, the network history data for each section is set to be allocated to a plurality of network distributed modes. For example, when the traffic value of the download server network is from 0 percent to 20 percent, the mode is assigned to one mode. In each mode, a fixed ratio is set. When a traffic value of a specific download server network is determined in the current time zone or the number of users connected to the PTP network is determined, a mode including a range to which each determined result belongs is selected, The ratio of the download amount set in each mode is extracted.

However, in addition to this, the ratio may be continuously set through a function having each traffic value and the number of access users as input values and the ratio as output values.

In other words, the step of extracting the network distributed mode in step S3 is to select the ratio matching the network history of the current section (current time zone).

When the step S3 is performed, a step (S4) is performed in which the download server network and the P2P network are distributed and connected to the terminal of the user according to a ratio, and accordingly control to download the file.

In the present invention, the user's terminal may divide and use the bandwidth and the like so that the network can be distributedly connected. In addition, the processor inside the user's terminal is also a processor capable of dividing processing functions to process a plurality of networks at the same time.

In general, a terminal capable of using a peer-to-peer network may be connected to a plurality of other users when connecting to the peer-to-peer network.

2 is a flowchart of a file download network distribution control method according to another embodiment of the present invention. In the following description, a description of overlapping parts with the description of FIG. 1 will be omitted.

Referring to FIG. 2, before the step S7 of loading the network distribution table, the step S5 of detecting traffic of the download server network and the step S6 of counting the number of users connected to the PTP network are performed. .

That is, in the embodiment of Fig. 1, the network history information including information on the traffic of the download server network or the number of users connected to the peer-to-peer network is stored in advance and loaded, thereby dynamically distributing the network at a predetermined ratio for each time zone. On the other hand, in the embodiment of Figure 2 by measuring this in real time, more dynamic control is possible.

After step S7, step S3 of FIG. 1 is not performed, and a network distributed mode matching one or more of the traffic of the current download server network and the number of users connected to the PTP network is selected. The description of the network distributed mode refers to a plurality of modes in which a ratio corresponding to the range of each traffic and the range of the number of access users is allocated as described in FIG. 1.

Subsequently, corresponding to step S4 of FIG. 1, according to the selected network distribution mode, that is, the ratio corresponding thereto, the amount of communication with the download server network and the direct communication from the download server, and the amount of communication with the P2P network and P2P communication Distributing, controlling to download the file (S9) is performed.

Since the embodiment of FIG. 2 measures the traffic and the number of access users in real time and immediately applies it to network distribution, there is a burden of additional data processing in the operation of the server, but more precisely and dynamically distributes the network. There is an advantage that it can.

3 illustrates a structure of a network system for implementing an embodiment of the present invention.

Referring to FIG. 3, it can be seen that the network distributed control apparatus 100 is included in the system as a subject performing the embodiments of FIGS. 1 and 2. As mentioned above, the network distributed control apparatus 100 adjusts the ratio of the network connected to the user terminal 200 according to the traffic of the download server 400 network and the number of users connected to the PTP network 300. It performs the function.

Accordingly, the network distribution control device 100 receives information on the number of connected users from the PTP network 300 and receives traffic information of the network from the download server 400.

On the other hand, when the user terminal 200 attempts to connect to the network, the P2P network 300 and the download server 400 are controlled to attempt to connect to each distributed.

4 is a block diagram of a file download network distribution control apparatus according to an embodiment of the present invention. In the following description, portions overlapping with the description of FIGS. 1 to 3 will be omitted.

Referring to FIG. 4, the file download network distribution control apparatus 100 according to an embodiment of the present invention may include a network history management unit 160, a timer 130, a distribution table management unit 140, and a network distribution control unit 150. Characterized in that it comprises a. The network distribution control unit 150 controls the network connection of the user terminal 200. The network history manager 160 is connected to the simulator 600.

As described above, the distributed table manager 140 stores different network distribution tables according to the unit download size of the file, and delivers them to the network distribution control unit 150 when network distribution control is performed.

The network history manager 160 receives and analyzes the history information of the download server network and the history information of the PTP network from the simulator 600.

5 illustrates a connection structure of the simulator 600 for implementing an embodiment of the present invention.

The simulator 600 performs a function of storing network history information from the P2P network 300 and the download server 400 in real time. Through this, the details of the traffic information of the past download server 400 network and the information on the number of users connected to the P2P network 300 will be accumulated and stored.

The information stored in the simulator 600 is transferred to the network history manager 160 (see FIG. 4) and analyzed as mentioned above.

4, the network history manager 160 receives the traffic information of the network of the download server 400 or the number of users connected to the PTP network 300 from the simulator 600. Either of the two types of information is used to select a network distributed mode. Alternatively, the network distributed mode may be selected using both kinds of information.

The network history manager 160 manages the network traffic of the download server 400 or the number of users connected to the PTP network 400 for each section. Managing each breakdown by section, for example, divides one day by a certain time zone (for example, time zone divided by three hours), and the average network traffic or the average number of access users in each time zone. Means to set the information.

The timer 130 performs a function of selecting a network distributed mode suitable for each time zone by notifying the information of each section according to one cycle, that is, the time zone during the day.

The network distribution controller 150 receives the network history information from the network history manager 160 via the distributed table manager 140 or directly from the network history manager 160. As mentioned above, the network history information includes one or more of the details of the network traffic of the download server 400 and the number of users connected to the PTP network 300.

In addition, the network distribution control unit 150 receives a network distribution table corresponding to the type of file from the distribution table management unit 140.

Thereafter, the network distribution control unit 150 selects a ratio, that is, a network distribution mode for each section divided by one period, using the network distribution table and the network history information, and accordingly, the user terminal 200 selects the download server network and the P2P network. To control distributed connections.

6 is a block diagram of a file download network distribution control apparatus according to another embodiment of the present invention. In the following description, portions that overlap with the description of FIGS. 1 to 5 will be omitted.

Referring to FIG. 6, a difference between the embodiment of FIG. 6 and the embodiment of FIG. 5 corresponds to a difference between the embodiment of FIG. 1 and the embodiment of FIG. 2. That is, instead of the network history manager 160, the server traffic detector 110 and the access user counter 120 exist.

The server traffic detector 110 detects the traffic of the download server 400 network in real time. In addition, the connection user counter 120 measures the number of users connecting to the P2P network 300 in real time.

Thereafter, as described with reference to FIG. 2, a network distribution table matching the type of file is selected from the network distribution tables managed by the distribution table manager 140. One or more pieces of information of the traffic of the download server 400 network measured by the server traffic detector 110 and the access user counter 120 and the number of users accessing the PTP network 300 and the selected network distribution table are network distribution controllers. The network distribution control unit 150 controls the network connection to the user terminal 200 by using the received information.

Figure 7 is an example of graphing the network traffic or the number of access users for the implementation of an embodiment of the present invention.

7 is an example in which traffic information of a download server network managed according to the embodiments of FIGS. 1 and 4 and information on the number of users connected to a P2P network are plotted for each time zone.

Referring to FIG. 7, one cycle in each embodiment of the present invention is set to one day (24 hours). In addition, each section is divided by 3 hours, and at the end time of each section (0, 3, 6, 9 o'clock, 12, 3, 6, 9 o'clock) Indicated. In addition, the example of FIG. 7 is an example in which the configuration corresponding to the embodiment of FIGS. 1 and 4 of the present invention is applied to a download server and a P2P network of an online game execution file.

First, at 6 am, the traffic of the download server network is 30% of the maximum allowed traffic, and the number of access users is measured at 500.

Over time, at 9 am, traffic has increased to 50% and the number of users is 600. Traffic and user numbers fluctuated, reaching 90% and 2000, respectively, at 0am.

In the graph of FIG. 7, the mode recorded under the number of connected users means a network distributed mode. Each ratio is determined according to the network distribution mode, which will be described in more detail with reference to FIG. 8.

The data corresponding to the graph of FIG. 7 is data generated by the network history management unit 160 of FIG. 4, which is compared with the network distribution table in the network distribution control unit 150, and a ratio according to each mode is selected so that the user terminal ( The network distribution of 200 is controlled.

8 shows an example of a network distribution table for implementing one embodiment of the present invention. In the following description, portions overlapping with the description of FIGS. 1 to 7 will be omitted.

Referring to Figure 8, a network distribution table 500 is shown for two file types (block sizes of 32 KB and 64 KB).

First, in the block size 510, types according to the data transmission / reception block size are classified as described above. Each network distribution table is managed by dividing the file into 32KB files and 64KB files.

First, a case in which the size of a block is 32 KB will be described. Information on the boundary size 520 is displayed. The information about the boundary size 520 is a criterion for determining whether to download data from a download server or data from a P2P network according to the size of the data.

For example, if the boundary size is 5KB, data up to 5KB is downloaded through the download server network, and data having a larger size is downloaded through the P2P network. At this time, when the file is finally downloaded, the size 530 of the blocks downloaded by the download server is 16MB, and the size 540 of the blocks downloaded through the P2P network is 513MB.

On the other hand, if the boundary size is 30KB when the block size is 32KB, the size 530 of the blocks downloaded by the download server is 57MB, and the size 540 of the blocks downloaded via the P2P network is 367MB. In other words, as the boundary size increases, the total cumulative size of blocks transmitted through the download server network also increases.

The same is true when the block size is 64KB. As the boundary size increases, the total size 530 of the blocks downloaded by the download server increases, and the total size 540 of the blocks downloaded through the P2P network decreases.

Accordingly, the ratio of the size 530 of the blocks downloaded by the download server to the size 540 of the blocks downloaded through the P2P network is determined in the network distribution table. Each ratio is a mode for it, and the modes 1 to 10 are matched.

The number assigned to each mode in the graph of FIG. 7 and the mode of FIG. 8 are implemented to match. Referring now to FIG. 7 and FIG. 8, first, the example of FIG. 7 is a graph when the block size is 64 KB. When the mode of 6 AM and 9 AM is compared, the number of connected users is 100. Despite the difference, the traffic of the download server network is about 20% different, and the modes are changed to 9 and 8 respectively.

In addition, when comparing 12 pm and 3 pm (15:00), the traffic of the download server network is the same as 40%, but the number of users connected to the P2P network is about 300, and the modes are 6 and 6, respectively. You can see something different with 7.

Also, as shown in FIG. 7, the criteria for changing modes may be set to increase the download rate through the connection to the P2P network as traffic increases or the number of access users increases.

9 illustrates an example of network distributed mode selection using network traffic and the number of access users for implementing an embodiment of the present invention. In the following description, the description of the parts overlapping with those of FIGS. 1 to 8 will be omitted.

That is, FIG. 9 illustrates an example of a method of allocating modes based on the traffic of the download server network and the number of users connected to the PTP network in FIG. 7.

Referring to FIG. 9, a server traffic row 710, an access user row 720, and a mode row 730 exist first. Numbers 1 to 5 are assigned to server traffic rows and access user rows 710 and 720, respectively. Numbers 1 to 5 divide the range of download server traffic and give an identification number for each range, or divide the range of the number of access users and give an identification number for each range.

Referring to the server traffic row 710, the download server network traffic is divided into five ranges from 0% to 100%, and a number 711 is assigned to each range 712. Accordingly, the traffic measured or included in the historical information matches any one of numbers 1 to 5.

Looking at the number of access users 720, assuming that there is a maximum of 2000 access users through measurement, divide the range 722 of the number of users into five intervals, and of the number 721 of 1 to 5, respectively Match any one. Accordingly, like the download server network traffic, the number of connected users measured or included in the historical information also matches any one of numbers 1 to 5.

The number of download server network traffic and the number of users connected to the P2P network can be matched to numbers for 1 to 5, respectively, and the mode can be assigned according to each combination of numbers. Referring to the mode row 730, it can be seen that various modes are set according to each number, and as in the embodiments of FIGS. 7 and 8, the download server network traffic increases or the number of users connected to the PTP network. As the number of modes increases, the number of modes decreases, and as the number of modes decreases, as shown in FIG. 8, the download rate through the P2P network increases.

9 is an example of mode selection when the download server network traffic and the number of users connected to the PTP network are simultaneously applied. Preferably, the range of the mode selection or the number of users connected to the PTP network according to the range of download server network traffic Of course, there may be a separate table of mode selection according to.
