WEB,认证服务器协同工作完成对,WLAN,用户的认证。,SC,用于用户在,WLAN,接入过程中的业务控制，包括强制,portal,等。,WEB+DHCP,认证流程,portal,服务器,完成向,WLAN,用户推送认证页面和门户网站。,radius,用户认证服务器,radius,用户认证服务器完成基于,WEB,方式的用户认证。,WEB+DHCP,认证流程,WEB+DHCP,认证流程,1,、用户通过标准的,DHCP,协议，通过,AC,获取到规划的,IP,地址。,2,、用户打开,IE,，访问某个网站，发起,HTTP,请求。,3,、,AC,截获用户的,HTTP,请求，由于用户没有认证过，就强制到,Portal,服务器。并在强制,Portal URL,中加入相关参数。,4,、,Portal,服务器向,WLAN,用户终端推送,WEB,认证页面。,5,、用户在认证页面上填入用户名、密码等信息，提交到,Portal,服务器。,WEB+DHCP,认证流程,6,、,Portal,服务器接收到用户信息，向,Radius,发出用户信息查询请求。,7,、,Radius,验证用户密码、查询用户信息，并向,Portal,返回查询结果及系统配置的单次连接最大时长,(SessionTimeout),、手机用户及卡用户的套餐剩余时长信息,(AvailableTime),。,8,、,如查询成功，,Portal,服务器按照,CHAP,流程向,AC,请求,Challenge,。如果查询失败，,Portal,直接返回提示信息给用户，流程至此结束。,9,、,AC,返回,Challenge,，包括,Challenge ID,和,Challenge,。,WEB+DHCP,认证流程,10,、,Portal,将密码和,Challenge ID,及,Challenge,做,MD5,算法后的,Challenge-Password,，和帐号一起提交到,AC,，发起认证。,11,、,AC,将,Challenge ID,、,Challenge,、,Challenge-Password,、,Called-Station-ID,和帐号一起送到中央,RADIUS,用户认证服务器，由中央,RADIUS,用户认证服务器进行认证。,12,、中央,RADIUS,服务器根据用户信息判断用户是否合法（对于省内预付费卡用户，还需要判断用户接入地和归属地是否一致）。,RADIUS,对用户密码分别进行静态密码和动态密码两次密码认证。如果其中一次成功，,RADIUS,向,AC,返回认证成功报文，并携带协议参数，以及用户的相关业务属性给用户授权。如果两次都失败，,RADIUS,向,AC,返回认证失败报文。,WEB+DHCP,认证流程,13,、,AC,返回认证结果给,Portal,服务器。（以及相关业务属性。）,14,、,Portal,服务器根据认证结果，推送认证结果页面。如果成功，根据编码规则判断帐户的归属地，推送归属地定制的个性化页面，并将认证结果、系统配置的单次连接最大时长、套餐剩余时长、自服务选项填入页面，和门户网站一起推送给客户,同时启动正计时提醒。如果失败，页面提示用户失败原因。,WEB+DHCP,认证流程,15,、,Portal,服务器回应,AC,收到认证结果报文。如果认证失败，则流程到此结束。,16,、认证如果成功，,AC,发起计费开始请求给中央,RADIUS,用户认证服务器。,17,、中央,RADIUS,回应计费开始响应报文，并将响应信息返回给,AC,。用户上线完毕，开始上网。,18,、在用户上网过程中，为了保护用户计费信息，每隔一段时间,AC,就向中央,RADIUS,用户认证服务器报一个实时计费信息，包括当前用户上网总时长，以及用户总流量信息。,WEB+DHCP,认证流程,19,、中央,RADIUS,计费服务器回应实时计费确认报文给,AC,。,20,、当,AC,收到下线请求时，向,RADIUS,用户认证服务器发计费结束报文。,21,、中央,RADIUS,计费服务器回应,AC,的计费结束报文,。,WEB+DHCP,认证流程,WEB,用户下线流程,WEB,用户下线流程包括用户主动下线和异常下线两类情况。异常下线指,AC,侦测到用户下线。,WEB+DHCP,认证流程,WEB+DHCP,认证流程,当用户需要下线时，可以点击认证结果页面上的下线机制，向,Portal,服务器发起一个下线请求。,1,、,Portal,服务器向,AC,发起下线请求。,2,、,AC,返回下线结果给,Portal,服务器。,3,、,Portal,服务器根据下线结果，推送含有对应的信息的页面给用户。,4,、当,AC,收到下线请求时，向向,RADIUS,用户认证服务器发计费结束报文。,5,、,RADIUS,用户认证服务器回应,AC,的计费结束报文,。,WEB+DHCP,认证流程,WEB+DHCP,认证流程,1,、,AC,侦测到用户下线，向,Portal,服务器发出下线请求。,2,、,Portal,服务器回应下线成功。,3,、当,AC,收到下线请求时，向计费服务器发计费结束报文。,4,、计费服务器回应,AC,的计费结束报文。,2/3,层隧道的具体应用场景及配置,1,、本地转发,AC,做无线控制器,+BRAS,使用（一般为串接）,AC,只做无线控制器（一般为旁挂）,2,、集中转发,三层隧道（串接、旁挂）,二层隧道（一般为旁挂）,本地转发（,AC+BRAS,）,本地转发（,AC,）,集中转发（三层隧道,-,串接）,集中转发（三层隧道,-,旁挂）,本地转发,本地转发,Login:bnas,Password:bnas,Bnasena,Password:super,Bans#config
