企业官网建设流程全解析

1.通信流程图

1. 建立TCP连接
2. SSL初始化，进行加密建立安全机制
3. 由CPE端发起HTTP请求，发送Inform报文，开始建立CWMP连接。Inform中使用Eventcode字段描述发送Inform请求的原因 如 6 CONNECTION REQUEST ，表示ACS要求建立连接。
4. 如果ACS通过CPE的请求，则连接建立。
5. 如果CPE无别的请求则发送一个空报文。满足HTTP报文请求/响应报文交互规则。
6. ACS查询CPE上设置的ACS URL的值
7. CPE将所需要获取的值返回给ACS。
8. ACS发现CPE的ACS URL是本机URL的值，于是发起Set请求，要求将CPE的ACS URL设置为备用ACS的URL的值。
9. 设置成功，CPE发送响应报文。
10. ACS无别的请求发送空报文。
11. CPE发送关闭连接

2.简单的报文实例
