网络系统互联与设计

摘要：由于互联网技术的发展，我们的社会正在以快速发展的形势迈向互联网的新兴时代。无限感知网络作为物联网的核心技术能够实现采集和监控各种的环境信息，然后对信息进行计算，汇总和存储，从而实现对监控区域环境数据的掌控。而现如今，存储数据记录最经常用的模式则是关系数据库。

异种网络的互联是目前网络技术发展中一定要解决的问题。针对此问题，国际标准化组织 (ISO)为实现计算机网络互联制定了开放系统互联标准 (0 5 1 ) , 这是一个比较理想的开放系统互联七层参考模型 , 但现阶段 0 5 1缺乏足够的产品支持 . 传输控制协议 (TCP)和网际协议 (IP) 简称TCP/IP, 在目前是一个“事实上”的网络互联标准协议。 T c p / I P 经过多年的研究和运用后 , 已逐步标准化 , 在世界上得到许多大公司的支持。

为了更好的进行异种网络的相联合，本文将分析LAN、WLAN、3G 网络、无线传感器网络、无线个域网、以及无线自组织网络六种异构网络的特点，分析了互联这六种异种网络在连接的时候所需要的各种系统软硬件技术。本文从STM32 和 FPGA 的双核心硬件结构进行分析，重新设计了异构网络互联系统，综合利用STM32 以及 FPGA 各自的优势提高了整个系统的事务处理能力和扩展

Interconnection and design of network system Abstract:Due to the development of Internet technology, our society is moving towards the emerging era of the Internet with the rapid development of the situation. As the core technology of the Internet of things, infinite perceived network can collect and monitor all kinds of environmental information, and then calculate, summarize and store the information, so as to realize the control of monitoring regional environmental data.

Today, the most frequently used pattern for storing data records is a relational database. The interconnection of heterogeneous networks is a problem that must be solved in the development of network technology at present. In response to this problem, the International Organization for Standardization (ISO) has developed an open System interconnection standard (0 5 1) for the interconnection of computer networks, which is an ideal seven-tier reference model for open System

interconnection, but at this stage 0 5 1 lacks sufficient product support. The Transmission Control Protocol (TCP) and the Internet Protocol (IP) are referred to as TCP/IP, which is currently a "de facto" standard protocol for network interconnection.

After years of research and application, Tc P/i P has been gradually standardized and is supported by many large companies in the world.

In order to better combine heterogeneous networks, this article will analyze LAN, WLAN, 3G network, no The characteristics of six heterogeneous networks of line sensor networks, wireless domain networks, and wireless self-organizing networks, and analyzes the various system hardware and software technologies that are needed for interconnection of six heterogeneous networks when connected.

This paper analyzes the dual-core hardware structure of STM32 and FPGA, designs the Heterogeneous network Interconnection system, comprehensively combines the advantages of STM32 and FPGA to improve the transaction processing ability and expansion of the whole system.
