As shown in
The data transmission controlling system 1 includes a start controlling module 11, a channel establishing module 12, a link line establishing module 13, a data receiving module 14, a data dividing module 15, a transmission control module 16, and a data combination module 17. In the embodiment, the first data transmission controlling device 100 further includes a storage unit 40, the second data transmission controlling device 200 further includes a storage unit 23.
The modules of the data transmission controlling system 1 are a collection of software instructions stored in the storage unit 40 and executed by the processing unit 10 or can be a collection of software instructions stored in the storage unit 23 and executed by the processing unit 22. In one embodiment, the processing units 10, 22 can be central processing units, digital signal processors, systems on a chip, or single chips, for example. In one embodiment, each of the storage units 40, 23 can be an internal storage system, such as a flash memory, a random access memory (RAM) for temporary storage of information, and/or a read-only memory (ROM) for permanent storage of information. Each of the storage units 40, 23 can also be a storage system, such as a hard disk, a storage card, or a data storage medium. In at least one embodiment, each of the storage units 40, 23 can include two or more storage devices such that one storage device is a memory and the other storage device is a hard drive. Additionally, one or more of the storage devices 40, 23 can be located external relative to the data transmission controlling system 1.
The start controlling module 11 controls the first data transmission controlling device 100 to transmit a conversation request to the second data transmission controlling device 200 when receiving a request for starting a conversation aggregation from a user. In the embodiment, the user can login a management interface of the first data transmission controlling device 100 and select a corresponding menu item to generate the request for starting the conversation aggregation. The first data transmission controlling device 100 can transmit the conversation request to the second data transmission controlling device 200 via any of the established network accessing paths.
The channel establishing module 12 establishes a transmission channel 102 between the first data transmission controlling device 100 and the second data transmission controlling device 200 when the second data transmission controlling device 200 accepts the conversation request. In the embodiment, the transmission channel is a Tunnel channel, and is a logical channel.
The link line establishing module 13 establishes a number of link lines 103 on the transmission channel according to each network accessing path of the network connection unit 30 of the first data transmission controlling device 100. In detail, a bandwidth of each link line 103 is the same and equal to a predetermined bandwidth (such as 1 megabit/s (M/s)), the link line establishing module 13 compares the bandwidth of each network accessing path and the predetermined bandwidth, and obtains a ratio of the bandwidth of each network accessing path and the predetermined bandwidth. The link line establishing module 13 then divides the each network accessing path to a number of link lines whose number are equal to the ratio, thus to establish a number of link lines on the transmission channel 102. For example, assuming the predetermined bandwidth is 1 M/s, and there are three network connection path A, B, and C of the network connection unit 30, and the bandwidth of the network connection path A is 5 M/s, the bandwidth of the network connection path B is 2 M/s, and the bandwidth of the network connection path C is 1 M/s. Then, the ratio of the bandwidth of the network accessing path A and the predetermined bandwidth is 5, the ratio of the bandwidth of the network accessing path B and the predetermined bandwidth is 2, and the ratio of the bandwidth of the network accessing path C and the predetermined bandwidth is 1. The link line establishing module 13 then divides the network accessing path A to five link lines 103, divides the network accessing path B to two link lines 103, and divides network accessing path C to one link line 103. Therefore, the link line establishing module 13 establishes eight link lines 103 on the transmission channel 102. In another embodiment, the link line establishing module 13 takes each network accessing path as one link line no matter the bandwidth of network accessing path is greater than the predetermined bandwidth or less than the predetermined bandwidth.
After the transmission channel 102 and the link lines 103 are established, the first data transmission controlling device 100 can transmit data to the second data transmission controlling device 200 via the transmission channel 102 including the link lines 103. Correspondingly, the second data transmission controlling device 200 also can transmit data to the first data transmission controlling device 100 via the transmission channel 102 including the link lines 103.
The data receiving module 14 is used to receives data to be transmitted. In the embodiment, the data to be transmitted can be the data transmitted to the second data transmission controlling device 200 from the first data transmission controlling device 100, and also can be the data transmitted to the first data transmission controlling device 100 from the second data transmission controlling device 200.
The data dividing module 15 divides each data packet of the data to be transmitted to a number of sub-packets according to the amount of the link lines 103 of the transmission channel 102. In the embodiment, an amount of the sub-packets divided from each data packet is equal to the amount of the link lines 103. The number of sub-packets can be less or more than the number of link lines 103.
The transmission control module 16 transmits the sub-packets of each data packet to a receiver, namely the first data transmission controlling device 100 or the second data transmission controlling device 200 respectively via the link lines 103 at the same time. In detail, each link line transmits one sub-packet and the sub-packets of each data packet can be transmitted in parallel via the link lines 103.
The data combination module 17 receives the sub-packets of each data packet, and combines the sub-packets of each data packet to the corresponding data packet in sequence to recover or reconstruct the data to be transmitted.
In detail, when the data dividing module 15 divides one of data packets to the number of sub-packets, the data dividing module 15 adds a unique label to each sub-packets of the data packets, and further adds a corresponding sequence number to one of the sub-packets according to a corresponding sequence that the sub-packets located in the data packet. For example, if one data packet is divided to eighth sub-packets by the data dividing module 15, the data dividing module 15 adds a unique label to all of the eight sub-packets and adds sequence numbers “1”-“8” respectively to a first sub-packet to an eighth sub-packet. Similarly, when another data packet is divided to eighth sub-packets by the data dividing module 15, the data dividing module 15 adds another unique label to all of the eight sub-packets of the another data packet and adds sequence numbers “1”-“8” respectively to a first sub-packet to an eighth sub-packet.
When the data combination module 17 receives the sub-packets, the data combination module 17 determines which sub-packets belong to the same data packet according to the unique label included in the sub-packets. The data combination module 17 then combines the sub-packets of the same data packet to generate the corresponding data packet in sequence according to the sequence number of each sub-packet.
In the embodiment, the data combination module further transmits the recovered data to a target address. In the embodiment, the target address can be an address of a terminal device connected to the first data transmission controlling device 100 or the second data transmission controlling device 200. For example, when the data to be transmitted is transmitted to the second data transmission controlling device 200 from the first data transmission controlling device 100, the target address can be an address of an Internet resource, the data combination module transmits the recovered data to the Internet resource. When the data is transmitted to the first data transmission controlling device 100 from the second data transmission controlling device 200, the target address can be an address of the terminal device 300, the data combination module transmits the recovered data to the terminal device 300.
In another embodiment, the first data transmission controlling device 100 is not limited to the router and the second data transmission controlling device 200 is not limited to the VPN server. The first data transmission controlling device 100 and the second data transmission controlling device 200 can be any type of devices communicate to each other.
In the embodiment, the data transmission controlling system 1 further includes a connection configuration module 18. The connection configuration module 18 controls the network connection unit 30 to establish each network accessing path in response to user operation. For example, the connection configuration module 18 configures and starts up the network card port 31 when the user inserts a network card into the network card port 31. The connection configuration module 18 also can configure and start up the WIFI module 33 or/and the PPTP module 34 in response to operations on a control interface of the first data transmission controlling device 100 after the user logins the control interface of the first data transmission controlling device 100.
Therefore, according to the present disclosure, the data can be transmitted via the number of link lines in parallel, which enhances the transmission speed.
In block 301, a start controlling module controls a first data transmission controlling device to transmit a conversation request to a second data transmission controlling device when receiving a request for starting a conversation aggregation from a user via a terminal device connected to the first data transmission controlling device.
In block 303, a channel establishing module establishes a transmission channel between the first data transmission controlling device and the second data transmission controlling device when the second data transmission controlling device accepts the conversation request.
In block 305, a link line establishing module establishes a number of link lines on the transmission channel according to each network accessing path of the network connection unit of the first data transmission controlling device. In detail, a bandwidth of each link line is the same and equal to a predetermined bandwidth (such as 1 megabit/s (M/s)), the link line establishing module compares the bandwidth of each network accessing path and the predetermined bandwidth, and obtains a ratio of the bandwidth of each network accessing path and the predetermined bandwidth. The link line establishing module then divides the each network accessing path to a number of link lines whose number are equal to the ratio, thus to establish a number of link lines on the transmission channel. The link lines can be any combination of actual or virtual link lines.
In block 307, a data receiving module receives data to be transmitted.
In block 309, a data dividing module divides each data packet of the data to be transmitted to a number of sub-packets according to an amount of the link lines of the transmission channel. In the embodiment, an amount of the sub-packets divided from each data packet is equal to the amount of the link lines. In detail, when the data dividing module 15 divides the data packet to the number of sub-packets, the data dividing module 15 adds a unique label to each sub-packets of one of the data packets, and further adds a corresponding sequence number to one of the sub-packets according to a corresponding sequence that the sub-packets located in the data packet.
In block 311, a transmission control module transmits the sub-packets of each data packet to a receiver respectively via the link lines at the same time.
In block 313, a data combination module receives the sub-packets of each data packet, and combine the sub-packets of each data packet to the corresponding data packet in sequence, thus to recover or reconstruct the data to be transmitted. In detail, the data combination module determines which sub-packets belong to the same data packet according to the unique label included in the sub-packets, and combines the sub-packets of the same data packet to the corresponding data packet in sequence according to the sequence number of each sub-packet.
In the embodiment, the method can further include: the data combination module further transmits the recovered data to a target address.
