什么是Windows Connect Now ? 对Wi-Fi 设备进行配置的解决方案

Windows Connect Now = Wi-Fi Protected Setup Windows Vista 的 WCN Windows Connect Now = Wi-Fi Protected Setup To avoid any confusion of where we are now with WCN – Windows Connect Now is Microsoft’s implementation of Wi-Fi Protected Setup. In fact the Wi-Fi protected setup uses Windows Vista to test out some of the scenarios.

Wi-Fi Protected Setup 这些解决方案都是不能相互兼容的! – Windows Connect Now 1.0* – SecureEZSetup* – OBC (One Button Configuration)* 这些解决方案都是不能相互兼容的! Smart Wireless Solutions – Network in a Box* Auto Link* Let us look at Wi-Fi Protected Setup in a little more detail – There were all these solutions which attempted to make wireless setup easier – Microsoft’s USB Key solution, Secure EZ Setup, AutoLink .. And a host of others. The problem however was they did not work with each other. The only way to easily setup a secure wireless home was to buy all you devices from the same manufacturer … well that is really not a solution. So in 2004 .. – A.O.S.S. (AirStation One-Touch Secure System)* – AutoSecure* – Quick SETUP buttons*

Wi-Fi Protected Setup Simple Configuration Working Group 成立于 8/2004 致力于解决家庭无线网络配置(WPA-Personal) 对WFA 的兴趣和参与 (9 companies submitted 6 proposals) Wi-Fi alliance formed the Simple Configuration working group. A number of companies were on this working group and came up with the Wi-Fi Protected Setup specification. We have come a long way since then .. today

Wi-Fi Protected Setup Today we have over 250 products that support Wi-Fi Protected Setup.

Windows Connect Now 以前 现在 I use this slide .. To show the power of the WPS .. On the left me trying to set up my Wireless Digital Home without WPS – definitely not a pretty picture .. And on the right is where WPS takes you. Andrea there is setting up here home network, printers, picture frame – no cables, no worries – she gets a consistent experience with every device. To Dig deeper ..

配置无线路由器 传统的步骤 Wi-Fi Protected Setup 拆开包装盒，给路由器通电 插入光盘并安装应用程序 无线搜索并连接无线路由 把网线连上路由器 输入PIN码进行验证 打开软件向导配置路由器 成功连接 断开网线连接 Let us analyze the steps in setting up a Wireless Router .. We took about 15 of the top selling APs and analyzed them .. This is what you need to do if you follow the instructions .. 1 2 3 4 5 Since not everyone follows the instructions – they power up the AP and just connect to it .. Leaving their network insecure. With WPS – we can make this easy and prevent connections from being insecure. Using the model of everyone powers up the AP and connects to it .. The user now sees a Wizard to setup the device .. That is setting up the AP .. Connection is what people do most frequently

连接到一个无线路由 传统的步骤 Wi-Fi Protected Setup 用户尝试连接网络 寻找密码 按下路由器上的Push Button 或者是输入PIN码 用网线连接路由器去寻找密码 成功连接 断开网线 连接网络，输入密码 1 2 3 4 5 6 And then there is setting up the device.

设备的生命周期 配置 安装 使用

配置一个无线设备 传统的步骤 Wi-Fi Protected Setup 打开包装盒，给设备通电 插入光盘并安装应用程序 选择设备和要加入的网络并连接 插入连接线(USB, Ethernet) 输入PIN码 输入相对应的网络信息包括WI-FI配置信息，或者SSID，密码等 设备成功加入网络 断开连接线 1 2 3 4 5 6 Once again I’d like to highlight the fact that WPS makes it simple and consistent.

协议概要 发现 认证 “Enrollee” 传送配置信息 “Registrar” That demo shows us the power of WPS .. Lets look into what is actually happening .. They way I look at it is that there are 3 phases – 1. Discovery – When you find the device 2. Authentication – You ensure that the device that you are connecting to is yours and yours only .. 3. Transfer of profile .. When you transfer the settings. It is also valuable to understand how this works in Windows because implementation can be fine tuned to provide a great experience .. “Registrar”

Windows 下的实现 设备发现 “Registrar” “Enrollee” 用户输入PIN码， 根据向导配置设备 M1 M2D M1 If we go down a level deeper and look at the architecture here is what is looks like .. 用户输入PIN码， 根据向导配置设备 M2 M3 – M8

架构 WCN Service Client Provisioning & Control Discovery Function Discovery API Query Manager WCN Provider WCN SSDP Provider SSDP WSD Provider WSD Registry PnP Provider Registry Provider Setup DI API Category Manager WCN Service You have the Function discovery Subsystem in Vista – which allows you discover most network devices such as UPnP using SSDP , WSD etc. WCN plugs right in here. The FD Provider talk to our service to discovery devices .. A client app uses FD to see these devices .. Client would be Network Explorer. For configuration it talks to our service. Now our service is not public – and we understand that people may want to write their own client apps – to maybe take some custom actions once the device is on the network. So ..

拓展性 WCN API Set We introduced some extensibilty … For discovery – you can use standard FD APIs to get WCN device .. Once the device is discovered, you can use NetSh commands to configure the Device .. Lets us look at how simple these are ..
