Description

Technical Field

[0001] The present invention relates to the field of network expansion of a half-duplex bus, and in particular to a network expansion method, device and electronic equipment of a half-duplex bus. Background Art

[0002] With the continuous development of Internet technology, data transmission has become an indispensable part of modern society. The transmission modes of data on the line can be divided into three types: simplex communication, half-duplex communication and full-duplex communication. In half-duplex communication, data can be transmitted in two directions, but at the same time, a channel only allows one-way transmission, so it is also called two-way alternating communication. If the transmission direction is to be changed, it needs to be switched by a switch. The half-duplex mode requires both the sending and receiving devices to be present at both ends of the transmission and reception. Since the half-duplex bus is low-cost, simple and easy to use, and can save transmission lines, there is still a large demand for the use of half-duplex. However, the half-duplex mode requires frequent changes in channel direction, which is inefficient. Single-path transmission is susceptible to network congestion and node failure. The transmission of large data packets is limited by bandwidth and is prone to packet loss, which makes it difficult for traditional transmission technology to meet the growing data transmission needs, especially under the requirements of high bandwidth and low latency. Therefore, it needs to be improved. Summary of the invention

[0055] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] Combine the following Figure 1-Figure 9 The invention describes a network expansion method, device and electronic device for a half-duplex bus.

[0057] like Figure 1 As shown, in one embodiment, a network expansion method for a half-duplex bus includes the following steps:

[0058] Step S100, parse the original data packet and cut it into multiple smaller data segments according to a preset segmentation rule, and assign a unique serial number to each data segment.

[0059] By adopting the data packet segmentation strategy, it is convenient to realize multi-path parallel transmission, thereby optimizing the transmission efficiency of large data packets.

[0060] Step S200, dynamically selecting multiple transmission paths according to real-time network conditions, where the network conditions include network bandwidth, transmission delay, packet loss rate, and error rate.

[0061] By selecting multiple paths according to network conditions to transmit segmented data simultaneously, multi-path transmission is facilitated to avoid transmission problems caused by congestion on a single path.

[0062] Step S300, regularly analyzing the network topology, identifying bottleneck nodes, and optimizing network transmission performance.

[0063] By identifying and eliminating bottleneck nodes, the overall transmission performance of the network can be improved.

[0064] Step S400, based on the unique sequence number, sequentially reorganize the segmented data and output a complete original data packet.

[0065] This is convenient for ensuring that the received segmented data can be accurately reassembled into the original large data packet.

[0066] The network expansion method of the half-duplex bus improves data transmission efficiency by dividing large data packets into multiple small segments and adopting a multi-path transmission strategy. It can effectively solve the problems of network congestion and limited transmission of large data packets caused by single-path transmission. At the same time, it optimizes network transmission performance by identifying bottleneck nodes, thereby facilitating dynamic adjustment of network configuration and improving the reliability and overall performance of half-duplex bus data transmission.

[0067] In this embodiment, see Figure 2 , parse the original data packet and cut it into multiple smaller data segments according to the preset segmentation rules, and assign a unique serial number to each segment data, including the following steps:

[0068] Step S110, receiving a large data packet to be transmitted.

[0069] Step S120, calculating the optimal number of segments and the size of each segment according to the network status and transmission requirements, where the transmission requirement is the maximum transmission unit of the network.

[0070] Determine an appropriate number of segments n based on factors such as network bandwidth, transmission delay, and error rate. The size of each segment data is denoted as d i (where i = 1, 2, ..., n), satisfying the following formula:

[0071]

[0072] Where D is the total size of the large data packet to be transmitted, and the formula indicates that the combination of all segmented data is exactly equal to the original data packet.

[0073] Step S130, based on a segmentation algorithm, the large data packet is segmented into multiple small segments.

[0074] Determine the segment size: Determine the size of each segment based on the network's MTU (Maximum Transmission Unit) and the current network conditions.

[0075] Determining the segment size is an important part of network communication. When transmitting data, the size of the data packet needs to be determined based on the MTU of the network. MTU refers to the maximum size of a data packet that can be transmitted at one time in the network. The MTU value may be different for different types of networks. In order to ensure that data packets can be effectively transmitted in the network, the size of each segment is usually set to be less than or equal to the MTU value.

[0076] The following is an example of a formula for determining segment size:

[0077] Segment size = min (MTU, maximum transmission unit under current network conditions),

[0078] In practical applications, network conditions, such as bandwidth, delay, packet loss rate, and other factors, also need to be considered to dynamically adjust the segment size to optimize transmission efficiency.

[0079] Split the data packet: Use a segmentation algorithm to evenly split the data packet D into n segments.

[0080] Step S140: assign a unique serial number to each segmented data.

[0081] By making each segment d i Contains the sequence number to facilitate subsequent reassembly.

[0082] In this way, parallel transmission of data can be achieved, greatly improving transmission efficiency and reliability.

[0083] In this embodiment, see Figure 3 , parse the original data packet and cut it into multiple smaller data segments according to the preset segmentation rules, and also include the following steps:

[0084] Step S150: Execute a CRC algorithm or other applicable verification algorithm on each segmented data to generate an initial verification code.

[0085] Among them, the CRC algorithm (Cyclic Redundancy Check) is a commonly used data transmission error detection technology. Its basic principle is to add one or more check bits (i.e., CRC code) to the sent data. After receiving the data, the receiving end uses the same CRC algorithm to calculate the check bit and compares it with the sent check bit to determine whether the data has changed during the transmission process.

[0086] The specific expression is as follows:

[0087] C i =CRC(d i ),

[0088] Among them, C i is the segmented data d i The check code “CRC” represents the CRC check algorithm.

[0089] Step S160, adding the initial check code to the end of the corresponding segmented data to form a new data packet.

[0090] This makes it convenient to transmit segmented data with checksums during the transmission process.

[0091] Step S170: extract the segmented data and the initial check code from the new data packet, and recalculate the check code of the segmented data to generate a new check code.

[0092] By extracting the initial check code and calculating the new check code, it is convenient to verify the integrity of the data by comparing the initial check code with the new check code.

[0093] Step S180: In response to the new check code being different from the initial check code, instruct the network to retransmit the segmented data.

[0094] When the new check code is the same as the initial check code, the data transmission is considered correct; if they are different, it is necessary to request retransmission of the segmented data.

[0095] By embedding a checksum in each segment, errors can be discovered and corrected in a timely manner during data transmission, greatly improving the reliability and accuracy of data transmission.

[0096] In this embodiment, see Figure 4 , dynamically select multiple transmission paths according to the real-time network conditions, including the following steps:

[0097] Step S210, obtaining performance data of each path in the network.

[0098] By monitoring the network status in real time, it is convenient to obtain performance data such as bandwidth, delay, packet loss rate, etc. of each path in the network.

[0099] Step S220: Analyze the performance data of each path and evaluate the transmission capacity of each path.

[0100] By analyzing the performance data of each path and then evaluating the transmission capacity of each path, it is convenient to match the appropriate path for each segmented data.

[0101] Step S230: Based on the evaluation result, multiple optimal paths are selected for data transmission.

[0102] By dynamically selecting multiple transmission paths according to the real-time network conditions so as to transmit the divided data segments in parallel, not only the data transmission speed is improved, but also the robustness of the entire transmission system is enhanced, ensuring that the data can reliably reach the destination.

[0103] In this embodiment, see Figure 5 ,Based on the evaluation results, multiple optimal paths are selected for data transmission, including the following steps:

[0104] Step S231 : for each segmented data, one or more optimal paths are dynamically selected from a set of predefined transmission paths according to the current network conditions.

[0105] Assuming that there are multiple networks, each network is equipped with real-time monitoring or status feedback, the quality or status of each network can be easily known, and the best one or more paths can be selected for data transmission.

[0106] Step S232: Send the segmented data to the optimal path.

[0107] Convenient to realize parallel transmission.

[0108] Step S233: in response to the degradation of the path performance, the segmented data on the path is transferred to other paths.

[0109] When it is found that the transmission rate of a certain path decreases or is interrupted by interference or damage, the segmented data on this path is transferred to other paths. Dynamic adjustment ensures that the data segments can be transmitted in the shortest time, while reducing the transmission delay caused by network congestion.

[0110] In this embodiment, see Figure 6 , regularly analyze the network topology, identify bottleneck nodes, and optimize network transmission performance, including the following steps:

[0111] Step S310, obtaining status information of all nodes and links in the network, the status information including bandwidth, delay and flow.

[0112] By real-time monitoring of the bandwidth, latency, traffic and other status information of all nodes and links in the network, it is convenient to regularly analyze the network topology.

[0113] Step S320, identifying nodes that limit network traffic according to algorithms in graph theory.

[0114] By using algorithms from graph theory, such as the maximum flow and minimum cut theorem, it is easy to identify nodes that restrict network flow.

[0115] The specific expression is as follows:

[0116] Bottleneck capacity = min c ∈C{c|c is the capacity of a link in the network},

[0117] Where C is the capacity set of all links in the network; bottleneck capacity refers to the bottleneck capacity in the network, that is, the maximum amount of data that can be transmitted in the network, which is determined by the smallest link capacity in the network; c is an element in the set C, representing the capacity of a certain link in the network; min c ∈C represents the operation of finding the minimum value in the set C; {c|c is the capacity of a link in the network} represents the capacity of all links in the network.

[0118] Step S330: Calculate and add a new path based on the network topology and link capacity.

[0119] By adding new links in the network, the capacity of the bottleneck node is increased, thereby improving the throughput of the entire network.

[0120] Step S340: Calculate the optimal routing strategy according to the new network topology.

[0121] By modifying the routing table in the network, traffic is redistributed to reduce the load on bottleneck nodes.

[0122] Adjusting routing policies is a key operation in network management, which aims to improve the overall performance of the network by optimizing the transmission path of data packets.

[0123] New routing strategy = optimization (current routing table, bottleneck node identification algorithm),

[0124] Among them, the bottleneck node identification algorithm is used to identify nodes with higher loads in the network. By modifying the routing table in the network, the traffic can be redistributed so that data packets bypass these bottleneck nodes, thereby reducing their load and improving the overall transmission efficiency of the network.

[0125] For example, the SPF (Shortest Path First) algorithm is used to calculate the optimal path for data packets from the source node to the destination node. If a node (such as node A) is found to be a bottleneck, the routing strategy can be adjusted by following the steps below:

[0126] Use network monitoring tools to identify bottleneck node A.

[0127] Calculate the shortest paths from all nodes in the network to other nodes, excluding the paths passing through node A.

[0128] Update the routing table to direct the traffic that originally passed through Node A to the alternative path.

[0129] Here is a simplified example:

[0130] Assume that there are four nodes A, B, C, and D in the network. Under the current routing policy, all traffic from B to D passes through A, causing A to become a bottleneck.

[0131] The adjusted routing strategy may be:

[0132] Traffic from B to D now goes through node C instead of A, which reduces the load on A.

[0133] In the routing table, this might appear as a change to the following entry:

[0134] Original route entry: B->A->D

[0135] New route entry: B->C->D

[0136] In this way, the traffic is redistributed and bypasses the bottleneck node A.

[0137] The specific embodiments are as follows:

[0138] Assuming that node X is the bottleneck node in the network, through analysis, it is found that the capacity of link XY is the smallest.

[0139] For optimization, a new link XZY is added between nodes X and Y so that traffic can be transmitted through the new path, reducing the load on link XY. At the same time, the routing strategy is adjusted so that part of the traffic is transmitted through the new path, thereby improving the overall performance of the network.

[0140] In this way, not only the efficiency of network transmission is improved, but also the robustness of the network is enhanced, ensuring the continuity and reliability of data transmission. The following is the final effect:

[0141] Improved throughput: By adding redundant paths and adjusting routing policies, the network throughput has been significantly improved.

[0142] Reduced latency: The optimized network reduces the latency of data transmission and improves user experience.

[0143] Enhanced reliability: The network can better adapt to traffic changes and reduce transmission failures caused by bottleneck nodes.

[0144] In this implementation, see Figure 7 , based on the unique sequence number, the segmented data is sequentially reassembled and the complete original data packet is output, including the following steps:

[0145] Step S410, acquiring segmented data on all transmission paths, each segmented data including a unique sequence number.

[0146] By collecting the segmented data with sequence numbers on all transmission paths, it is convenient to sort and reassemble the segmented data.

[0147] Step S420, sorting the segmented data based on the sequence number.

[0148] Since the sequence number can indicate the position of the segmented data in the original data packet, it is convenient to sort the segmented data according to the sequence number.

[0149] Step S430: storing the sorted segmented data in a temporary buffer.

[0150] By collecting all segmented data in a temporary buffer, it is convenient for subsequent reorganization.

[0151] Step S440, in response to all the segmented data being transmitted to the temporary buffer, the segmented data are spliced ​​one by one according to the order of the sequence numbers to complete the data reorganization, and the reorganized complete original data packet is output.

[0152] The specific reorganization process expression is as follows:

[0153]

[0154] Where D' is the complete data packet after reassembly, d i (where i = 1, 2, ..., n) represents the size of each segment data, s i Represents each segment data d i ’ a corresponding sequence number.

[0155] The specific embodiments are as follows:

[0156] Assume that three segmented data d1′, d2′, and d3′ are received, and their sequence numbers are 1, 2, and 3 respectively.

[0157] The three segmented data are sorted according to the sequence numbers, and then they are concatenated in sequence to finally restore the original data packet D′.

[0158] In this way, the integrity of the data and the reliability of the transmission can be ensured, and the original data can be accurately reconstructed even in the case of multi-path transmission and possible out-of-order arrival of segmented data.

[0159] The network expansion device of the half-duplex bus provided by the present invention is described below. The network expansion device of the half-duplex bus described below and the network expansion method of the half-duplex bus described above can be referred to each other.

[0163] The analysis module 830 is used to regularly analyze the network topology, identify bottleneck nodes, and optimize network transmission performance.

[0164] The output module 840 is used to sequentially reassemble the segmented data based on the unique sequence number and output a complete original data packet.

[0165] In this embodiment, the parsing module 810 is specifically used for:

[0166] Receive large data packets to be transmitted;

[0167] Calculate the optimal number of segments and the size of each segment based on the network status and transmission requirements. The transmission requirement is the maximum transmission unit of the network.

[0169] Assign a unique sequence number to each segment data.

[0170] In this embodiment, the parsing module 810 is further specifically used for:

[0171] Execute a CRC algorithm or other applicable check algorithm on each segmented data to generate an initial check code;

[0174] In response to the new check code being different from the initial check code, the network is instructed to retransmit the segmented data.

[0175] In this embodiment, the selection module 820 is specifically used to:

[0176] Obtain performance data for each path in the network;

[0177] Analyze the performance data of each path and evaluate the transmission capacity of each path;

[0178] Based on the evaluation results, multiple optimal paths are selected for data transmission.

[0179] In this embodiment, based on the evaluation results, multiple optimal paths are selected for data transmission, specifically for:

[0180] For each segmented data, one or more optimal paths will be dynamically selected from a set of predefined transmission paths according to the current network conditions;

[0181] Send segmented data to the optimal path;

[0182] In response to a path performance degradation, segmented data on the path is transferred to other paths.

[0183] In this embodiment, the analysis module 830 is specifically used for:

[0184] Obtain status information of all nodes and links in the network, including bandwidth, latency, and traffic;

[0185] Based on algorithms from graph theory, identify nodes that restrict network traffic;

[0193] Output the complete original data packet after reassembly.

[0194] The network expansion device of the half-duplex bus improves the data transmission efficiency by dividing the large data packet into multiple small segments and adopting a multi-path transmission strategy. It can effectively solve the problems of network congestion and limited transmission of large data packets caused by single-path transmission. At the same time, it optimizes the network transmission performance by embedding check codes in each segment and identifying bottleneck nodes, thereby facilitating dynamic adjustment of network configuration and improving the reliability and overall performance of half-duplex bus data transmission.
