1.通信流程图建立TCP连接SSL初始化进行加密建立安全机制由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。如果ACS通过CPE的请求则连接建立。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。ACS查询CPE上设置的ACS URL的值CPE将所需要获取的值返回给ACS。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。设置成功CPE发送响应报文。ACS无别的请求发送空报文。CPE发送关闭连接2.简单的报文实例POST/acs/xx HTTP/1.1Host:acs.avsystem.com:10301User-Agent:xxx CPE-0.21.3.31(3.6.13)Authorization:Digest
