## 2. Definition of Space for Aerospace Cultural and Creative Industries

Aerospace big data industry: Beidou Industrial Park is a collective model based on enterprises, and jointly built by the military and local relevant forces with the support of the government and China’s satellite related departments. It is applied to the satellite industry to serve the public. The construction of the industrial park has accelerated the all-round development of the Beidou system and the application of related industries, and promoted the common development of the satellite industry and related industrial chains.High score industrial park is a platform for big data mining of satellite data. Tong and Zhu’s application of high score project, Earth observation data, is a basic resource in China. With the extension of the application field of high score project, more and more fields tried to apply high score project to their own projects. In this paper, the resolution obtained from the high-resolution satellite to the ground has a large number of high-resolution observation rate data, which provides a basis for practical application in related fields such as land, agriculture, environmental protection, and meteorology [4].Aerospace Equipment Industry: The civil transformation industry of the aerospace technology and the application of Aerospace Science and Technology development industry in various fields, such as Qianguai high score, Tianyi Zhongfen and Lishui communication, realize the services of satellite-related industries through satellites, and form a satellite constellation to achieve comprehensive coverage and serve the applications to improve in various fields. The aerospace equipment industry is gathering talents with high knowledge and high R&D ability to carry out scientific and technological development and application in the aerospace field through the combination of data and high-tech innovative technology.Aerospace cultural and creative industry space is an office environment, generally located in cities with convenient transportation and relatively developed economy, with a high-tech atmosphere and knowledge transmission channels. The infrastructure of network communication broadband has high requirements and good operation ability when dealing with dense data because aerospace information technology itself is to process data and needs a large amount of data analysis, the role of network communication broadband is, particularly, important [5].


## 3. Space Industry Spatial Feature Service Data Design

### 3.1. High Availability Continuous Communication with Multiple Interfaces

The data are transmitted to the integrated service optical transceiver through multiple external lines. Considering that the dense transmission of data will cause heavy load transmission, in view of this problem, the model establishes a separate service route. When the service is overloaded, the independent route and independent hardware interface will lose the service. Under this model, multiple hardware interfaces and multiple external lines are established for hot standby, which can timely prevent the congestion of a large business model. The specific description is shown in Figure1:Figure 1
Multi-machine room and multi-interface data access mode of aerospace cultural and creative industry space.In Figure1: The external line access bandwidth is larger. The access router introduces the encryption and compression of communication module between the public cloud and the private cloud. The distance between the machine rooms is greater than 200 m, to realize the disaster recovery backup of the machine room, and the hot standby control of the heartbeat line between the access router and the core switch. The bypass router adds a DDoS diversion function, behavior control function, internal load balancing function, port priority management function, etc;


### 3.2. Cloud Computing Facilities and Cloud Storage Facilities

Cloud computing is a kind of distributed computing, which means that the/a huge data computing processing program is decomposed into countless small programs through the network “cloud,” and then processed and analyzed through the system composed of multiple servers. These small programs get the results and then return them to users. In the cloud computer room, multiple core switches accessing the computer room are linked at the same time, and the large bandwidth special direct connection between the core switch and the cloud computer room can be realized under different routing modes. Each cloud computer room is equipped with a functional backplane switch, which is directly connected to the load balancer to uniformly distribute traffic to the resource hosts in the whole cloud computer room. The global load balancing function is configured between/within the load balancers of different computer rooms to realize the unified virtualization of all cloud computer room equipment in the whole park. The specific description is shown in Figure2:Figure 2
General implementation mode of cloud computing and cloud storage for aerospace cultural and creative space.In Figure2: Disaster recovery and backup function using multiple cloud facilities: The resource hosts include floating-point computing host group, storage host group, and multi-threaded computing host group. In the server cluster, while providing web services and app services, it also provides task segmentation and virtual machine services. AI administrators can divide resource hosts in accordance with task requirements and virtualize them to provide services for a single host. Virtual machines can be built and removed at any time.

## 4. Simulation Verification of High Availability and Wide Bandwidth Communication

The Simulink component in MATLAB is loaded, the simulation model for the above overall high availability and large bandwidth communication model algorithm is built, the data prediction module of high availability and large bandwidth communication system based on the algorithm is built, the data prediction module for general system in the technical market with reference to the group is selected, and the data performance of the two is compared. (query)TheT value and p value of the bivariate t-check come from the bivariate t-check process, where the t value is the value of the output result. When t > 10.000, it is considered that there is statistical consistency between the two columns of data, and the greater the t value, the greater the consistency; the p value is the log value of the output result. When p<0.05, it is considered that the result data is within the confidence space. When p<0.01, it is considered that the result data has significant statistical significance. The smaller the p value, the higher the degree of confidence. Subject to the length, only the calculation algorithm of t value (value) is explained here, such as formula (1):(1)tValue=x¯−μσx/n−1,x¯,μ=1n,m∑i=1n,mxi,σx=1n−1∑i=1nxi−x¯2.Among which x¯ is the arithmetic mean of the investigated sample sequence; μ is the average value of the reference sample sequence; n is the number of nodes of the investigated sample sequence; m is the number of nodes in the reference sample sequence; and σx is the standard deviation rate of the investigated sample sequence.Each network must have a certain time difference from the sending of signal to the final reception. This is the network delay, which cannot be avoided by every network. When you need to save a file to the network, the data in the file must pass through the network interface card, hub, or transmission cable when it reaches the hard disk of the server storing it. Although it feels that it will be stored immediately after typing the keyboard, although it is electronic transmission, it will inevitably go through the transmission link. However, there must be a short delay from the moment of operation to the moment when the server receives data. The main reasons affecting the network delay are as follows: first, there are too many direct routing hops from the local machine to the server, which will lead to the need for transfer processing in the process of data transmission, and will certainly lead to the increase of network delay time; Second, if the network bandwidth is not enough, it will also affect the transmission efficiency; Third, the processing bandwidth is insufficient. This simulation experiment is to verify the network transmission speed of the special system through different loads.


### 4.1. Impact of High Load Intranet Communication on Core Access Services

In order to verify the network delay of the special system to the core access service under the intranet load of 0.5tbps, 1tbps, 5tbps, 15tbps, and 45tbps, the network transmission speed, feasibility and advantages of the special system are verified by comparing them to the general system.

It can be seen from the table data that when the intranet load is 0.5 and 1 tbps, there is no great difference between the network delay of the special system and the general system, which shows that under the condition of small intranet load, the ordinary system can also carry out communication transmission well, and the advantages of the special system cannot be reflected at this time. With the increase in load, the advantages of the special system are reflected. Figure 3 is made in accordance with the data in Table 1, which makes it easier to observe the data of the two systems;Figure 3

However, when the private cloud load is 1 tbps and 5 tbps, the gap between the two is not obvious. When it is greater than 15 tbps, the network delay of the private system is far less than that of the general system. The following Figure 5 is made according to the data in Table 3;Figure 5

## 6. Summary

With the continuous expansion of China’s industrial scale, the cultural and creative industry has become an important force leading to the innovation and development of various industries. As the aerospace cultural and creative industry most closely combined with the national high-tech development, it has gradually become the development force of key for cultural and creative industries because of its unique charm. At present, the establishment of China’s Aerospace Industrial Park is not perfect, the characteristics and the functions are not obvious, which leads to the inability to play its role in absorbing domestic and foreign private capital and skilled talents, and also affects the investment and establishment of big data service platform. Therefore, the way of publicity and promotion of China’s Aerospace Science and Technology needs to be transformed, and the leisure function, science popularization project and economic function of China’s Aerospace Science and Technology also need to be developed, which needs to rely on the establishment of China’s aerospace cultural and creative (cultural and creative) industry [9]. The aerospace industry is the representative of China’s scientific and technological level and R&D ability. It needs economy, highly educated talents and high technology to support scientific research and development and drive the all-round development of aerospace and economy. Through the physical outgoing lines with high availability and large bandwidth, the research optimizes the cloud computing route in the park, improves the high availability performance of the network under the large business mode of the park, and finally improves the increase in occupancy rate, GDP, and total service revenue of the park, so as to promote the development of aerospace culture and creative economy led by high-tech means.
