摘要:随着Internet 的迅猛发展，越来越多的企业对互联网的依赖越来越大，在对设施农业方面尤为明显，人们需要实时掌控诸如温度、湿度及各种土壤熵情数据参数等，以便对温室大棚的环境调节控制。通过MPLS VPN网络架构的实现，使设施农业中的参数能够极为快速、安全的传输到监控平台。
本论文结合温室设施农业的现状，对设施农业数据的传输设计并搭建了可行的网络构架：将MPLS技术应用于设施农业数据的传输网络。此方案以OSPF协议搭建IGP拓扑，并将MPLS VPN运用于IGP拓扑中，提供安全的互联网接入。本设计首先架构拓扑，实现MPLS的VPN的传输，在两端利用无线网络，连接MPLS主干区域，一端编辑无线MPLS数据帧，将温度湿度及各种土壤熵情数据参数以自定义字节的方式完成组包，另一端完成无线MPLS数据帧的拆解，从而极大的方便了数据的深入处理及远程监控。

Abstract:With the rapid development of Internet, more and more enterprises more and more depend on the Internet, in especially for facility agriculture, people need to control such as temperature, humidity and various soil entropy conditions data parameters, so that the greenhouse environment control. Through the implementation of MPLS VPN network architecture, the parameter in agriculture can be extremely fast, secure transmission to the monitoring platform.
In this paper, combined with the status quo of greenhouse agriculture, transport design of the facility agriculture data and build the network architecture and feasible: the application of MPLS technology in facility agriculture data transmission network. This scheme uses OSPF protocol to build the IGP topology, MPLS and VPN used in IGP topology, provide safe access to the internet. The first design structure, realize the transmission of MPLS VPN, at both ends by using the wireless network, connecting the MPLS backbone area, end edit wireless MPLS data frame, the temperature and humidity and various soil entropy sentiment data parameters to the custom byte mode to complete the set of packages, dismantling the other end complete wireless MPLS data frames, thereby greatly to facilitate the further processing and remote monitoring data.
