[0043] In addition, in the following description, specific details are provided in order to facilitate a thorough understanding of the examples. However, one skilled in the art will understand that the application can be practiced without these specific details.

[0044] Figure 2 is a structural schematic diagram of a wireless network card provided by an embodiment of the present application, as shown in Figure 2As shown, the wireless network card includes: a wireless antenna, which can be connected to the Wi-Fi transmitting hardware of the transmitting module or the Wi-Fi receiving hardware of the receiving module via an RF switch. In the transmitting module, after the upper layer generates data, it is processed by the Wi-Fi baseband module, for example, by performing Orthogonal Frequency Division Multiplexing (OFDM) modulation to generate a baseband signal for transmission. This baseband signal is then passed to the Wi-Fi RF module for processing, such as up-conversion, to generate a radio frequency (RF) signal for transmission. Finally, it is connected to the wireless antenna via the RF switch and transmitted, thus completing the entire transmission process. In the receiving module, when the wireless antenna receives the RF signal, it is passed to the Wi-Fi RF module for processing via the RF switch, such as down-conversion, to generate the baseband signal for reception. The baseband signal is then fed into the Wi-Fi Baseband Module for processing, such as OFDM demodulation, to ultimately recover the received data and pass it to the Upper Layer, thus completing the entire reception process.

[0045] Traditional wireless network cards (NICs) rely on Carrier Sense Multiple Access with Collision Avoid (CSMA / CA) to handle contention and data transmission. In CSMA / CA, only one NIC can transmit at a time; other NICs must wait until the first NIC finishes transmitting (i.e., the channel becomes idle) before they can compete for the channel and transmit data. This mechanism, allowing only one NIC to access the network at a time, leads to low wireless transmission efficiency in wireless data centers, thus impacting the overall operational efficiency of the data center.

[0046] Based on this, the embodiments of this specification propose a processing solution: such as Figure 3 As shown, the wireless network card is removed at the wireless data center node, and a dedicated wireless transmitter and wireless correlator are used for data transmission and processing.

[0047] The technical solutions provided by the embodiments of the present application are described below with reference to the drawings.

[0048] Figure 3 is a structural schematic diagram of a wireless data center provided by an embodiment of the present application, as Figure 3 indicated in the description, the present application provides a wireless data center system, comprising: a mapping node (Map) and a reduction node (Reduce), a wireless sending module is arranged on the mapping node, and a wireless correlation module is arranged on the reduction node; the wireless sending module has a single antenna, i.e., a sending antenna, which is specially used for processing data sending; the wireless correlation module also has a single antenna, i.e., a receiving antenna, which is specially used for processing data receiving.

[0049] In the embodiment of the present application, the wireless sending module sends data through the sending antenna, and the wireless correlation module receives data through the receiving antenna, and the sending antenna and the receiving antenna work on the same channel.

[0050] In the embodiment of the present application, by deleting the traditional wireless network card, using a dedicated wireless sending module and a wireless correlation module, all the Map nodes are allowed to send data in parallel, and the efficiency of wireless transmission is increased.

[0051] Specifically, in the wireless data center scenario, based on the characteristics of the Map node and the Reduce node (i.e., the Map node is responsible for classifying data, and the Reduce node is responsible for processing a certain type of data), different simplex wireless modules can be configured for these nodes. Therefore, the Map node uses a simplex (i.e., single-direction transmission) wireless sending module, and the Reduce node uses a simplex wireless correlation module. That is, the wireless sending module and the wireless correlation module use a simplex communication mode.

[0052] The wireless sending module in the mapping node in the embodiment of the present application is described in detail below.

[0053] In the present application, each mapping node is allocated an orthogonal sequence, and the length of the orthogonal sequence is determined according to the number of mapping nodes.

[0054] Figure 4 is a structural schematic diagram of a wireless sending module provided by an embodiment of the present application, as Figure 4 indicated, the wireless sending module comprises: a first radio frequency unit and an orthogonal sequence modulation unit, and the orthogonal sequence is contained in the orthogonal sequence modulation unit; the two ends of the first radio frequency unit are connected with the sending antenna and the orthogonal sequence modulation unit, respectively.

[0055] Specifically, after the wireless sending module receives the data transmitted by the upper layer, the data is modulated by the orthogonal sequence in the orthogonal sequence modulation unit to generate a first baseband signal, the first baseband signal is transmitted to the first radio frequency unit for data processing to generate a first radio frequency signal, and the first radio frequency signal is transmitted to the reduction node through the sending antenna.

[0056] In an optional embodiment, the wireless sending module comprises one sending antenna, which is connected to the wireless sending module. The overall structure of the wireless sending module is similar to that of a conventional Wi-Fi, and the main difference is that the orthogonal sequence modulation is used instead of the conventional OFDM modulation of Wi-Fi.

[0057] In the present application, each mapping node is assigned a unique orthogonal sequence. The overall length of the orthogonal sequence is determined according to the number of Map nodes in the wireless data center network.

[0058] In the wireless sending module, the upper layer generates data and delivers the data to the wireless sending module. The wireless sending module modulates the data using the orthogonal sequence. After generating the orthogonal sequence, the wireless sending module directly transmits the orthogonal sequence as a baseband signal to the first radio frequency unit for processing, such as up-conversion of the signal, thereby generating a transmitted first radio frequency signal (RF signal), and finally transmitting the first radio frequency signal through the sending antenna, thereby completing the entire transmission process.

[0059] Specifically, in the embodiment of the present application, one reduction node can simultaneously receive signals transmitted by multiple mapping nodes.

[0060] The wireless-related modules in the reduction node are described in detail below.

[0061] Figure 5 is a structure diagram of a wireless-related module provided by the embodiment of the present application, as Figure 5 shown, the wireless-related module comprises a second radio frequency unit and a plurality of orthogonal sequence matching demodulation units.

[0062] The two ends of the second radio frequency unit are respectively connected to the receiving antenna and the plurality of orthogonal sequence matching demodulation units.

[0063] Specifically, one reduction node is associated with multiple mapping nodes, and simultaneously receives first radio frequency signals transmitted by the multiple mapping nodes.

[0064] In the embodiment of the present application, each orthogonal sequence matching demodulation unit corresponds to an orthogonal sequence modulation unit.

[0065] As Figure 5As shown, after the wireless related module receives the second radio frequency signal transmitted by the receiving antenna, the wireless related module performs data processing on the second radio frequency signal through the second radio frequency unit to generate a second baseband signal, and transmits the second baseband signal to the plurality of orthogonal sequence matched demodulation units for matched demodulation to obtain data transmitted by each of the plurality of mapping nodes related to the reduction node, and transmit the data to the upper layer.

[0066] In the second baseband signal, components of the first radio frequency signal transmitted by the plurality of mapping nodes are included, and each of the plurality of orthogonal sequence matched demodulation units extracts the components corresponding to the first radio frequency signal transmitted by the mapping node corresponding to the orthogonal sequence modulation unit to obtain data transmitted by each of the mapping nodes.

[0067] In an optional embodiment, as shown in Figure 5 As shown, the wireless related module includes one receiving antenna, and the receiving antenna is connected to the wireless related module. In the wireless data center, the Reduce node needs to receive feedback from all Map nodes at the same time. Here, a plurality of orthogonal sequence matched demodulation units are arranged on the Reduce node.

[0068] Specifically, the wireless related unit includes n orthogonal sequence correlators, each of which is responsible for performing correlation calculation of a certain orthogonal sequence and corresponds to each of the Map nodes. In the wireless related unit, after the receiving antenna receives the second radio frequency signal, the wireless related unit transmits the second radio frequency signal to the second radio frequency unit for processing, such as down-conversion of the signal, to generate a received second baseband signal, and then the second baseband signal is transmitted in parallel to all the orthogonal sequence correlators and is subjected to correlation demodulation. In the second baseband signal, components of the first radio frequency signal transmitted by the plurality of mapping nodes are included.

[0069] In the process of matched demodulation of the orthogonal sequence, the wireless related module performs cross-correlation calculation (i.e., matched demodulation) on the received second baseband signal and each of the orthogonal sequences. The second baseband signal includes components of the first baseband signal transmitted by each of the Map nodes, i.e., components of the plurality of orthogonal sequences. At this time, only the same sequence as in the correlation process can be extracted, and the rest of the components are equal to 0 due to the orthogonality. The wireless related module performs matched demodulation through a set of cross-correlation modules of the orthogonal sequences, so that data of each of the Map nodes can be obtained in parallel, and finally fed back to the upper layer for further data processing required by the Reduce node.

[0070] In the embodiments of the present specification, a wireless sending module and a wireless related module based on orthogonal sequences are provided. By using the wireless sending module, the wireless related module, and the superposition principle of the orthogonal sequences, the parallel access function of the wireless data center can be realized.

[0071] The application allows all Map nodes to send data in parallel in a wireless data center scenario, thereby increasing the efficiency of wireless transmission; compared with traditional standard Wi-Fi transmission, the application uses correlation calculation, which has anti-interference capability, and thus has better anti-interference performance and good stability than traditional Wi-Fi transmission; in traditional Wi-Fi transmission, only one node can transmit at each time due to the use of the carrier sense multiple access with collision avoidance (CSMA / CA) access mechanism. In the application, the circuit design of orthogonal sequences is used to allow multiple Map nodes to send data at the same time, and the wireless correlation module uses a set of orthogonal sequences to perform matching in parallel, thereby realizing the function of parallel sending and receiving of orthogonal sequences.

[0072] The embodiments of the present application also provide a wireless data center communication method, which is suitable for the wireless data center system and includes a plurality of Map nodes and a Reduce node.

[0073] Figure 6 is a flowchart of a wireless data center communication method provided by the embodiments of the present application, as shown in Figure 6 , which includes:

[0074] Step S1: determining the number of orthogonal sequences according to the number of Map nodes in the wireless data center system, and setting the orthogonal sequences in the orthogonal sequence modulation units of the Map nodes.

[0075] Step S2: obtaining an orthogonal sequence matrix according to the number of orthogonal sequences, distributing the orthogonal sequence matrix to the Map nodes and the Reduce node, placing the orthogonal sequence matrix in the Reduce node, and generating orthogonal sequence matching demodulation units corresponding to the orthogonal sequence modulation units in the Map nodes according to the orthogonal sequence matrix.

[0076] Step S3: initializing the Map nodes, and inputting the orthogonal sequences as parameters into the orthogonal sequence modulation units.

[0077] Step S4: initializing the Reduce node, and initializing the orthogonal sequence correlators in the orthogonal sequence matching demodulation units according to the number of orthogonal sequences.

[0078] Specifically, when the wireless data center system is set up, firstly, the number of orthogonal sequences is calculated according to the number of Map nodes, and by default, the wireless data center has only one Reduce node, but there are multiple Map nodes. One Map node needs one orthogonal sequence. Then, the length of the orthogonal sequence is determined according to the number of orthogonal sequences, and the corresponding orthogonal sequence matrix is generated. The longer the length of the orthogonal sequence is, the more the number of sequences that can be contained is. After the orthogonal sequence matrix is generated, the Reduce node needs to have a complete copy of the orthogonal sequence matrix, and according to the orthogonal sequence matrix, the orthogonal sequence matching demodulation unit required to be used locally is generated. On the Reduce node, a plurality of orthogonal sequence correlators in the orthogonal sequence matching demodulation unit are pre-constructed (the number is greater than the number of orthogonal sequences actually required), and then according to the number of orthogonal sequences actually required, the use is started. The Map node only saves the orthogonal sequence corresponding to the Map node, and inputs it into the orthogonal sequence modulation unit as a parameter.

[0079] After everything is finished, the wireless data center system can start working. In addition, in the wireless access stage, the application adopts the method of time slot synchronous transmission instead of the method of traditional wireless network CSMA / CA contention access, which is more efficient.

[0080] In the traditional CSMA / CA, multiple nodes need to compete for the channel, only the winner can perform wireless transmission, and only when the winner is the only one node, the receiver can successfully demodulate the data. In the application, the data sent by the Map node is mapped into different orthogonal sequences, so the Map node can send at the same time. Figure 7 is a schematic diagram of the wireless sending module in the wireless data center provided by the embodiment of the application adopting time slot synchronous transmission, as shown in Figure 7 The entire time axis is divided into multiple time slots according to the sending length of the orthogonal sequence. Each time slot corresponds to the sending time of the orthogonal sequence, and the time between nodes is synchronous.

[0081] Figure 7 is a schematic diagram of the wireless sending module in the wireless data center provided by the embodiment of the application adopting time slot synchronous transmission, as shown in Figure 7 includes time slot 1, time slot 2 and time slot 3, and the time axis is divided into multiple time slots, and multiple Map nodes can send data at the same time in each time slot, such as Map node 1 (M1), Map node 2 (M2), Map node 3 (M3) and Map node 4 (M4) in time slot 1, time slot 2 and time slot 3.

[0082] When the wireless data center system is in operation, all Map nodes will send orthogonal sequences simultaneously after the time slot begins. Since the different sequences are orthogonal, the Reduce nodes can use the orthogonal sequence correlator in parallel for identification and demodulate to obtain the information corresponding to all Map nodes at the same time.

[0083] Specifically, during communication, multiple mapping nodes simultaneously send orthogonal sequences to the reduction node in the same time slot, with each orthogonal sequence representing the data sent by the mapping node. When the reduction node receives multiple orthogonal sequences, it performs matching and demodulation through the orthogonal sequence matching and demodulation unit, thereby acquiring the data sent by multiple mapping nodes.

[0084] Figure 8 This is a schematic diagram of a data packet sent by a Map node and the generated orthogonal sequence provided in an embodiment of this application, as shown below. Figure 8 As shown, taking Map node 1 as an example, in the actual content of the transmitted wireless frame, Map node 1 will determine the content based on the upper-layer data (such as...). Figure 8 The bit information of the data packet shown, such as 10110…1, is mapped one by one to an orthogonal sequence for transmission. If the bit content is 1, then the transmission content is 1 multiplied by the orthogonal sequence 1, that is, it is transmitted in the positive phase. If the bit content is 0, then the transmission content is -1 multiplied by the orthogonal sequence 1, that is, it is transmitted in the negative phase, forming the transmission content of Map node 1.
