Description

Technical Field

[0001] The present invention relates to the technical field of communication network optimization, and in particular to a communication network optimization system. Background Art

[0002] With the rapid development of Internet technology, Internet communication technology has provided great convenience for people's various devices. As more and more terminal devices join the communication network, the data transmission links are complicated, and the network resources are unevenly distributed, which is prone to data congestion, resulting in a large delay in the data transmission process. The existing technology usually plans the resource allocation of nodes according to the communication network topology. However, due to the changeable characteristics of the network topology, the existing technology cannot make accurate adjustments in time according to the changes in the network topology, which easily causes some nodes to have only a small number of data transmission tasks, and a large number of resources are idle, resulting in a large amount of resources being wasted. In addition, the user terminal under the edge gateway may have a poor network and a greatly reduced communication capability. Since the existing technology will not update the communication link of the user terminal, the user terminal occupies the communication link, resulting in the inability to transmit other communication data. When the user manually switches the communication link, since the user cannot understand the transmission status of each communication link, it is easy to cause the transmission task arranged by the system to be disrupted, resulting in data transmission disorder. A large amount of data is accumulated at the entrance of the communication link waiting for transmission, wasting a lot of time. Therefore, it is very necessary to design a communication network optimization system that improves resource utilization and reduces communication delay. Summary of the invention

[0007] According to the above technical solution, the data collection module includes a data acquisition module and a historical transmission data entry module. The data acquisition module is used to collect communication data sent by the user terminal, and the historical transmission data entry module is used to enter the historical transmission data of the user terminal into the system.

[0008] According to the above technical solution, the transmission management module includes a node management module, which is used to analyze the data transmission habits of the user terminal and adjust the resource allocation of the edge node and the resource occupancy of the user terminal at the edge node according to the user transmission habits.

[0009] According to the above technical solution, the transmission management module includes a link management module, which is used to analyze the data uplink rate of the user terminal and the resource margin of the communication link jump node, and adjust the communication link of the user terminal according to the analysis result.

[0010] According to the above technical solution, the network optimization module includes a transmission detection module and a resource scheduling module. The transmission detection module is used to analyze and compare the download rate of the user terminal and the cache resource margin of the jump node. The resource scheduling module adjusts the transmission task of the jump node and the resource allocation of the receiving terminal according to the analysis results.

[0011] According to the above technical solution, the operation method of the network optimization system mainly includes the following steps:

[0012] Step S1: collect the communication data sent by the user terminal in real time through the data acquisition module, collect the topology of the network environment in which the user terminal is currently located, and enter the historical transmission data of the user terminal into the system through the historical transmission data entry module;

[0013] Step S2: After the data is entered into the system, the system starts the node management module, starts analyzing the usage habits of the user terminal, adjusts the connection relationship between the user terminal and the edge node according to the analysis results, and performs resource pre-allocation;

[0014] Step S3: When selecting a communication link, the system analyzes the uplink throughput rate of the user terminal, adjusts the transmission mode of the jump node and switches the communication link according to the analysis result;

[0015] Step S4: When the user switches the network environment, the system analyzes whether there is any residual data in the communication link, and retransmits the residual data according to the analysis result;

[0016] Step S5: The system detects the download rate of the receiving terminal in real time, analyzes the cache margin of the jump node, adjusts the transmission task scheduling of the jump node according to the analysis result, and merges the transmitted data according to the mark in the data block to obtain complete data.

[0017] According to the above technical solution, step S2 further includes the following steps:

[0018] Step S21: Obtain historical data transmission records of the user terminal, identify the transmission time of the user terminal and the corresponding transmission data volume, extract the usage time characteristics of the user terminal, fuse all the usage time characteristics of the user terminal to obtain the usage time characteristics of the user terminal, identify the usage time characteristics of the user terminal, and if the user terminal is in use at the target time, mark the user terminal as in use, otherwise mark it as not in use;

[0019] Step S22: Retrieve the topology of the network environment where the current user terminal is located, establish a network model based on the topology, identify the mark in the user terminal connected to the target edge node, and if the mark in the user terminal is unused, release the bandwidth allocated to the edge node connection port, otherwise the system continues to detect;

[0020] Step S23: Obtain the transmission request of the user terminal, identify the load rate of the first edge node to which the user terminal is currently connected, and when the load rate of the first edge node is greater than the system threshold, identify the number of user terminal connections and the load rate of the surrounding target edge nodes. If the load rate and the number of user terminal connections of the target edge node are both less than the threshold, call the target edge node transmission port to establish a temporary link with the user terminal for data transmission. If the load rate of the target edge node is less than the threshold and the number of user terminal connections is greater than the threshold, call the resources of the target edge node to compensate the first edge node. Otherwise, the system continues to detect and identify the startup status of the original link connection port in the target edge node. If the original link connection port is started, call the resources in the adjacent edge node to compensate the target edge node. Otherwise, the system continues to detect.

[0021] According to the above technical solution, step S3 further includes the following steps:

[0022] Step S31: retrieve the bandwidth allocated to the uplink task of the user terminal and the network strength, retrieve the corresponding influence coefficient α on the transmission rate in the database according to the uplink bandwidth allocated to the user terminal, and retrieve the corresponding influence coefficient β on the transmission rate in the database according to the network strength;

[0023] Step S32: retrieve the uplink throughput of the user terminal and calculate the transmission rate of the user terminal using the formula In the formula, V represents the transmission rate of the user terminal, M represents the uplink throughput of the user terminal within the rated time, and T represents the rated time for the user terminal to transmit data. By comparing with the database, if the transmission rate of the user terminal is less than the minimum threshold, the port of the first edge node connected to the user terminal is obtained, and the data is cached in the first edge node port. After the caching is completed, the data is transmitted again. Otherwise, the system continues to detect.

[0024] According to the above technical solution, step S4 further includes the following steps:

[0025] Step S41: when transmitting data, the first edge node encapsulates the data of the user terminal, cuts the data packet into m×n data blocks of equal size, injects the target receiving terminal interface of the data into the data block, identifies the network fluctuation frequency, and when the network fluctuation frequency of the user terminal is greater than the threshold, the system anchors the communication link between the user terminal and the first edge node. If the user terminal is connected to the first edge node, the communication link is encapsulated and the data in the communication link is cached. Otherwise, the system continues to transmit data. After the user terminal re-establishes the connection with the first edge node, the communication link is used to continue to transmit data;

[0026] Step S42: After the user switches the user terminal network environment, the user terminal establishes a connection with the second edge node, identifies the data cached in the edge node, and if there is a user terminal mark in the cached data, transmits the data to the second edge node, identifies the load rate of the jump node, and if the load rate of the jump node is less than the threshold, anchors the jump node as the target jump node, and establishes a communication link with the target jump node for data transmission. Otherwise, the system continues to detect and monitors the load rates of the remaining jump nodes in real time. If there is a jump node with a load rate less than the load rate of the target jump node, a communication link is established with the jump node for data transmission. Otherwise, continue to detect.

[0027] According to the above technical solution, step S5 further includes the following steps:

[0028] Step S51: Identify the remaining data cache capacity of the jump node, calculate the difference between the remaining data cache capacity of the jump node and the amount of transmitted data, if the difference is less than the system threshold, call the edge node transmission port on the receiving terminal side, establish an auxiliary link, and transmit the data to the edge node on the receiving terminal side for auxiliary caching, otherwise identify the receiving terminal mark in the data block, obtain the receiving terminal data transmission port according to the receiving terminal mark, establish a communication link between the jump node and the receiving terminal, transmit the data to the receiving terminal through the communication link, identify the code in the data block, and fuse the data in the receiving terminal according to the code to obtain complete data.

[0029] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention controls the number of user terminals connected to the edge node within a threshold range and recycles unused port resources, thereby avoiding occupying the resources of the edge node when the user terminal is not in use, resulting in resource waste, thereby greatly improving the resource utilization of the system; by transferring the user terminal data to the target edge node for transmission when the load on the first edge node is too large, the edge node resources can be fully utilized, the resource utilization is greatly improved, and the impact of the edge node transmitting data under a large load on the transmission speed is reduced, data congestion is avoided, and communication delay is reduced; by analyzing the uplink transmission rate of the user terminal and caching the user terminal data with a lower transmission rate, it can be avoided that the user terminal always occupies the transmission link of the first edge node and the communication link between the first edge node and the jump node, resulting in a large amount of data being needed The boundary points queue up to wait for transmission, wasting a lot of time, which greatly reduces the communication delay of the system. By encapsulating the communication link, the data being transmitted can be saved to the first edge node when the user terminal is disconnected from the first edge node, avoiding data loss and thus protecting data security. By real-time monitoring of the load rate of the jump node and replacing the jump node with a smaller load and faster transmission rate, the system's data transmission rate can be faster, thereby reducing the data transmission time and further reducing the system's communication delay. By analyzing whether the remaining data cache capacity of the jump node can accommodate the data and using the edge node on the receiving terminal side for auxiliary caching, it is possible to avoid insufficient data cache capacity of the jump node, resulting in data congestion in the jump node, which makes it impossible for other data to be transmitted to the receiving terminal through the jump node, wasting a lot of time waiting for data transmission, thereby greatly reducing the communication delay of the system.

[0040] The operation method of the network optimization system mainly includes the following steps:

[0041] Step S1: collect the communication data sent by the user terminal in real time through the data acquisition module, collect the topology of the network environment in which the user terminal is currently located, and enter the historical transmission data of the user terminal into the system through the historical transmission data entry module;

[0042] Step S2: After the data is entered into the system, the system starts the node management module, starts analyzing the usage habits of the user terminal, adjusts the connection relationship between the user terminal and the edge node according to the analysis results, and performs resource pre-allocation;

[0046] Step S2 further comprises the following steps:

[0047] Step S21: Obtain historical data transmission records of the user terminal, identify the transmission time of the user terminal and the corresponding transmission data volume, extract the usage time characteristics of the user terminal, fuse all the usage time characteristics of the user terminal to obtain the usage time characteristics of the user terminal, identify the usage time characteristics of the user terminal, and if the user terminal is in use at the target time, mark the user terminal as in use, otherwise mark it as not in use;

[0048] Step S22: retrieve the topological structure of the network environment where the current user terminal is located, establish a network model according to the topological structure, identify the mark in the user terminal connected to the target edge node, and if the mark in the user terminal is unused, release the bandwidth allocated to the edge node connection port, otherwise the system continues to detect, and by controlling the number of user terminals connected to the edge node within the threshold range and recycling the unused port resources, it can avoid occupying the resources of the edge node when the user terminal is not in use, resulting in resource waste, thereby greatly improving the resource utilization of the system;

[0049] Step S23: Obtain the transmission request of the user terminal, identify the load rate of the first edge node to which the user terminal is currently connected, and when the load rate of the first edge node is greater than the system threshold, identify the number of user terminal connections and the load rate of the surrounding target edge nodes. If the load rate and the number of user terminal connections of the target edge node are both less than the threshold, call the target edge node transmission port to establish a temporary link with the user terminal for data transmission. If the load rate of the target edge node is less than the threshold and the number of user terminal connections is greater than the threshold, call the resources of the target edge node to compensate the first edge node. Otherwise, the system continues to detect and identify the startup status of the original link connection port in the target edge node. If the original link connection port is started, call the resources in the adjacent edge node to compensate the target edge node. Otherwise, the system continues to detect.

[0052] Step S32: retrieve the uplink throughput of the user terminal and calculate the transmission rate of the user terminal using the formula Wherein, V represents the transmission rate of the user terminal, M represents the uplink throughput of the user terminal within the rated time, and T represents the rated time for the user terminal to transmit data. By comparing with the database, if the transmission rate of the user terminal is less than the minimum threshold, the port of the first edge node connected to the user terminal is obtained, and the data is cached in the first edge node port. After the cache is completed, the data is transmitted again. Otherwise, the system continues to detect. By analyzing the uplink transmission rate of the user terminal, the user terminal data with a smaller transmission rate is cached, which can avoid the user terminal from occupying the transmission link of the first edge node and the communication link between the first edge node and the jump node all the time, resulting in a large amount of data queuing at the boundary point waiting for transmission, wasting a lot of time, and greatly reducing the communication delay of the system.

[0054] Step S41: when transmitting data, the first edge node encapsulates the data of the user terminal, cuts the data packet into m×n data blocks of equal size, injects the target receiving terminal interface of the data into the data block, and identifies the network fluctuation frequency. When the network fluctuation frequency of the user terminal is greater than the threshold, it means that the network environment of the user terminal is unstable. The system anchors the communication link between the user terminal and the first edge node. If the user terminal is connected to the first edge node, the communication link is encapsulated and the data in the communication link is cached. Otherwise, the system continues to transmit data. After the user terminal re-establishes the connection with the first edge node, the communication link is used to continue to transmit data. By encapsulating the communication link, the data being transmitted can be saved to the first edge node when the user terminal is disconnected from the first edge node, thereby avoiding data loss and protecting data security.

[0055] Step S42: After the user switches the user terminal network environment, the user terminal establishes a connection with the second edge node, identifies the data cached in the edge node, and if there is a user terminal mark in the cached data, transmits the data to the second edge node, identifies the load rate of the jump node, and if the load rate of the jump node is less than the threshold, anchors the jump node as the target jump node, and establishes a communication link with the target jump node for data transmission. Otherwise, the system continues to detect and monitors the load rates of the remaining jump nodes in real time. If there is a jump node with a load rate less than the load rate of the target jump node, a communication link is established with the jump node for data transmission. Otherwise, the system continues to detect. By real-time monitoring of the load rate of the jump node and replacing the jump node with a smaller load and a faster transmission rate, the data transmission rate of the system can be faster, thereby reducing the data transmission time and further reducing the communication delay of the system.

[0056] Step S5 further comprises the following steps:

[0057] Step S51: Identify the remaining data cache capacity of the jump node, calculate the difference between the remaining data cache capacity of the jump node and the amount of transmitted data, if the difference is less than the system threshold, call the edge node transmission port on the receiving terminal side, establish an active link, and transmit the data to the edge node on the receiving terminal side for auxiliary caching, otherwise identify the receiving terminal mark in the data block, obtain the receiving terminal data transmission port according to the receiving terminal mark, establish a communication link between the jump node and the receiving terminal, transmit the data to the receiving terminal through the communication link, identify the code in the data block, and fuse the data in the receiving terminal according to the code to obtain complete data. By analyzing whether the remaining data cache capacity of the jump node can accommodate the data, and using the edge node on the receiving terminal side for auxiliary caching, it is possible to avoid insufficient data cache capacity of the jump node, resulting in data congestion in the jump node, resulting in other data being unable to be transmitted to the receiving terminal through the jump node, wasting a lot of time waiting for data transmission, thereby greatly reducing the communication delay of the system.
