嵌入式TCPIIP协议是为了解决以低端MCU为核心的嵌入式系统实现与Internet的互联而提出的一种方案。在了解了现有解决嵌入式系统实现网络化的各种方案之后，通过对标准TCP/IP的详细分析，并结合嵌入式系统的特点，提出了与其它方案有所不同的一种实现嵌入式系统与Internet互联的解决方案:嵌入式TCP/IP协议。该方案主要是从嵌入式系统现有的实际情况出发，以满足实用为目的，在数据传输的效率和准确性之间进行了一定的折衷，通过简化通信协议，实现了嵌入式系统与Internet的互联。-TCPIIP agreement is embedded in order to solve the low-end MCU as the core of embedded systems with Internet connectivity and a proposed program. Understanding of the existing solutions in embedded systems to achieve network-based programs, the adoption of the standard TCP/IP detailed analysis, combined with the characteristics of embedded systems, and other programs put forward a different realization of embedded systems and Internet connectivity solutions: Embedded TCP/IP protocol. The program is available from the embedded system the actual situation in order to meet practical for the purpose of data transmission between the efficiency and accuracy of a certain amount of compromise, by simplifying the communication protocol, the realization of embedded systems and Internet- Internet.
