摘　　要：车载网络的设计技术可以分为两类:以仿真和测试为主的传统设计方法,以及以协议设计为主的方法。传统方法将每个节点对协议的要求拼凑起来,通过仿真测试的方法检验协议的正确性,最终得到通讯协议。Volcano使用第二类方法,它通过系统设计技术,用理论方法对系统的时序建模,分析设计系统的通讯协议,保证系统的实时性能以及协议的正确性,最终发布正确的通讯协议。本文将介绍传统设计方法的局限性以及Volcano新方法的优势。The design method of automotive networking can be divided into two categories. One is so called 'error and trial'. It relies too much on test and simulation to test feasibility and correctness of protocol. Another method is a totally new method to design the protocol. Volcano belongs to this system engineering design technology. Customer only need input parameters as required. Volcano can automatically design the whole system and release a reliable protocol. The core idea is model the timing of the communication, and using theoretical method to assign message's ID and period to guarantee the whole system's real time performance. This paper discusses the two methods and does some comparison.
