The reason is indeed a bit exhausting in coding, so this chapter is not finished yet. I truly regret using the leave note at the beginning of the month, so the update will probably be a little late, probably around one o'clock in the morning. By then, just refresh this chapter.
Sotis I also think, when it's actually exhausting to code like this, should I just take a leave, but really can't bring myself to do it, which leads to the current situation. Every ti, I ponder life, why keep writing? Isn't it better to honestly be a Programr?

1 Introduction
Currently, communication technology is developing rapidly, with obvious characteristics of various networks. After years of reform and innovation, the transmission rate of wireless access technology is gradually approaching the limit. In this context, to satisfy multiple business demands, multi-network writing is required. However, traditional writing chanisms, in terms of network transmission resource usage, cannot be used simultaneously and efficiently, cannot effectively ensure high-efficiency transmission business, and will increase energy consumption issues during transmission, leading to interference problems during transmission. Therefore, many scholars have conducted research on multi-network data transmission thods. In literature [1], Shi Lingling and Li Jingzhao researched secure data transmission chanisms in heterogeneous networks, mainly adopting an optimized AES-GCM certified Encryption algorithm combined with SHA-based Digital signature thods for data transmission; in literature [2], Zhou Jing and Chen Chen researched a data security model based on heterogeneous networks, with pre-encryption processing of data and establishing secure transmission channels for data transmission. Both thods can achieve certain effects but also have certain inadequacies. To address the above inadequacies, this paper applies Machine Learning thods to secure data transmission in multi-source heterogeneous networks to solve current issues. Experintal results indicate that the secure data transmission technology effectively solves existing problems, with practical application significance.
2 Multi-source Heterogeneous Network Data Preprocessing
In secure data transmission over multi-source heterogeneous networks, much data is useless, necessitating selecting relevant data sources for transmission to enhance accuracy and efficiency. During effective data source selection, the importance of relationships between Attributes is asured [3-4], capturing highly correlated data. The calculation expression is as follows: (1), T representing the comprehensive table number of all data sources, (i,j) representing the correlation between example source classes. Based on the importance judgnt of data sources, the data table collection with the highest correlation degree can be selected, reducing unrelated tables. After completing the preferential data source selection, analyze the Attributes, as a data source is composed of a set of Attributes, whose features reflect the basic information of data to be transmitted. Mainly asured by the correlation of data tuples, analyzing the occurrence frequency of tuple data, defined by tuple data density, as shown in Figure 1. In Figure 1, ε represents the radius of the specified neighborhood. Following this idea, weights are assigned to each tuple data in the above dataset [5-7], with the expression as follows: (2), w(C) indicating Attribute weight, w(tk) indicating the number of core tuples, δ indicates outliers, w(tb) indicating the number of edge tuples.
3 Multipath Parallel Transmission Architecture
Upon completing the above preprocessing, establish a multipath parallel transmission architecture, mainly as follows: pre-divide traffic, traffic division is used at the sending end to split large data blocks into data units of different or sa sizes [8], with size determined by the grain size of communication flow division. It mainly falls into the following categories: First, in packet-level business segntation, packets are the smallest constituent units of data flow, so the granularity of segntation thods is minimal, and packet probabilities are mutually independent and can be sent to the sending end; Second, flow-level traffic division [9], encapsulating specific destination addresses in header, then aggregating packets sharing the sa destination address into data flows, these distinct data flows are independent and distinguished by unique flow identifiers. Flow-level division techniques effectively resolve data distortion impacts on multipath transmission [10]. Third, sub-flow level traffic division, the sa destination header data flow is split into multiple sub-flows, all sub-flows' packets have the sa destination address, sowhat resolving load imbalance in flow division algorithms. Multipath parallel transmission architecture is as shown in Figure 2. Besides, in bandwidth aggregation architecture, the scheduling algorithm determines business transmission patterns and business sub-flow scheduling order [11], ensuring orderly arrival of business sub-flows at the receiving end, next discussing data scheduling.
4 Bandwidth Scheduling Formulation
For data transmission over multi-source heterogeneous networks, when the bandwidth of a path reaches a certain value, the network bandwidth will continuously increase, and transmission performance becos relatively stable. Excessive bandwidth allocation will reduce spectral utilization rate, leading to a waste of spectral resources. Under the increasingly tight spectral resources, scheduling and managing bandwidth across various paths in multipath parallel transmission not only ensures transmission performance but also efficiently utilizes resources. Processing mainly is as follows: First, adopting Machine Learning thods for effective bandwidth estimation, reasonably estimating wireless bandwidth resources each sub-flow can fully utilize, eting high throughput requirents with less bandwidth resources, which is key to bandwidth scheduling algorithms. Therefore, a coupling congestion control algorithm is employed for combined control of sub-flows, with its expression as follows: (3), MSS represents the maximum length of ssages constant, set by protocol, RTTi, PLRi respectively represent the return delay and packet loss rate of the sub-flow's path. Second, parater filtering processing, due to wireless channel diversity and ti-varying characteristics, link paraters and path effective bandwidth undergo dynamic changes and have errors. To remove errors, Kalman filter is applied to network paraters for precise estimates. The Kalman filter is a discrete ti recursive estimation algorithm, computing more accurate current mont Status using differential recursion, current Status asurent, last mont Status, and forecast error. In discrete control systems research, linear stochastic differential equations are adopted as follows: (4), xk, xk-1 respectively represent Status paraters at mont k and k-1, Ak, Bk respectively represent system paraters, matrix form in multi-model systems, representing Status transition matrix and input matrix, uk represents control input paraters, wk represents noise during computation. Third, bandwidth scheduling, assuming multipath connection C contains n sub-flows, each sub-flow is independent, each occupying a single path for data transmission, the scheduling process is as shown in Figure 3. Based on the above bandwidth scheduling process, finally establish channel security protocol, ensuring secure data transmission over multi-source heterogeneous networks. Security protocol is composed of SSL protocol, rule establishnt protocol, tunnel Information protocol, etc. Among them, SSL protocol mainly includes certification algorithm and Encryption algorithm, with all server-side ssages encrypted through SSL protocol to ensure security of ssage communication, rule establishnt protocol includes connection information and ssage identification, record table successfully matches, generating socket, relaying ensures information relay on VPN technology channel application. OpenVPN programming is the main thod for realizing tunnel Information protocol. The client sends request command ssages to establish connection with the server. After connection, the server writes encrypted and authenticated Information into tunnel Information area according to SSL protocol, achieving data exchange and transmission with the client. Channel security protocol structure is as shown in Figure 4. During data transmission, transmit according to the above channel security protocol to complete machine learning-based secure data transmission over multi-source heterogeneous networks.
5 Experintal Comparison
To verify the effectiveness of the designed machine learning-based secure data transmission technology for multi-source heterogeneous networks, experintal analysis was conducted, comparing the heterogeneous network secure data transmission chanism in literature [1], heterogeneous network-based data security model in literature [2], and effectiveness of three systems. Experintal datasets as shown in Table 1. Based on collected experintal data, it's evident that selected experintal data is increasing, better verifying the effectiveness of three thods, mainly comparing transmission delay, data transmission interruption situations, and link packet loss rate, as detailed below.
5.1 Comparison of Transmission Delay
We compared the transmission delay of three thods, and the comparison results are shown in Figure 5. By analyzing Figure 5, it is found that for transmission on Google's public dataset, the transmission delays of all three thods are relatively small. However, as the amount of transmitted data increases, the transmission delays in all three thods increase. Nonetheless, by comparison, it is evident that the transmission delay of the machine learning-based multivariate heterogeneous network data security transmission technology in this study is the smallest, less than the other two traditional thods.
5.2 Comparison of Data Transfer Interruption
We compared the data transfer interruption situations after applying three transmission technologies, and the comparison results are shown in Figure 6. Figure 6 reveals that the transmission technology in this study experiences the least data transfer interruptions, with fewer occurrences than the two traditional transmission technologies in several experints.
5.3 Comparison of Packet Loss Rate
The study's machine learning-based multivariate heterogeneous network data security transmission technology and two traditional transmission technologies were used for data transmission, and the packet loss rate comparison results of the three thods are shown in Figure 7. By analyzing Figure 7, it is found that the link packet loss rate in traditional heterogeneous network secure data transmission chanisms is the highest, greater than the data security model based on heterogeneous networks and the transmission technology in this study. To sum up, the machine learning-based multivariate heterogeneous network data security transmission technology in this study has lower transmission delay and packet loss rate compared to the two traditional transmission technologies. This is because the study's transmission technology preprocessed multivariate heterogeneous network data in advance, formulated bandwidth scheduling sches, and established secure transmission protocols, thus improving the effect of secure transmission in multivariate heterogeneous networks.
6 Conclusion
This paper designed a machine learning-based multivariate heterogeneous network data security transmission technology, and experints validated the effectiveness of this research technology. This technology can improve the efficiency of data transmission and reduce the packet loss rate of data transmission, and has significant practical application value. However, due to research ti limitations, the multivariate heterogeneous network data security transmission technology in this study still has certain shortcomings. Thus, further optimization is required in subsequent research.
