管理和控制接口的定义描述为web services的方式。
为了实现即插即用交互，标准定义了设备发现，设备发现标准基于WS-Discovery规范
2.1 Wdsl(describe services)
2.2 web services
2.3 WS-Discovery
2.4 Soap(message transfer)
2.5 Xml （describe syntax）
3 技术名词定义
3.1 自组织网络（Ad-hoc network）
3.2 基础设备集（Basic Service Set）
3.3 兼容性(capability)
3.4 架构网络（Infrastructure network）
3.5 NVT（Network Video Transmitter）
3.6 NVD（Network Video Display）

3.9 PCKS（公共密码学标准）
3.10 Pre Shared Key（设备静态码）
3.11 PullPoint（拖消息的资源）
3.12 Remote Discovery Proxy（远程搜索设备协议）
3.13 Service Set ID（无线网络身份验证）
3.14 Wi-Fi Protected Access（）
3.15 MTOM（Message Transmission Optimization Mechanism），是W3C的MTOM的消息传输优化机制，有效地发送的二进制数据和从Web服务方法。将消息传输优化机制 (MTOM) 消息编码与WSHttpBinding 一起使用。MTOM是一种机制，用来以原始字节形式传输包含SOAP消息的较大二进制附件，从而使所传输的消息较小。

4.5 Event handling
Base on OASIS WS-BaseNotification and WS-Topics
the reuse of a rich notification framework
PullPoint notification pattern(not allow real-time notification)
The PullPoint pattern allows a client residing behind a firewall to receive real-time notifications while utilizing the WS-BaseNotification framework.
Event WSDL file.

Transport-level security
Message-level security
IEEE 802.1X
5 web services
所有的管理和控制命令都是基于web services
服务提供者（设备如NVT, NVD, NVS, NVA 等）
服务请求者（The client ）
   
using the Universal Discovery, Description and Integration Registry (UDDI)
WS-Discovery
Web Services allow developers the freedom to define services and message exchanges
WS-I Basic Profile 2.0
5.1 overview
device management service    the entry point

ter:ActionNotSupported,
5.2
A WSDL document consists of the following sections:
types – Definition of data types using XML schema definitions.
message – Definition of the content of input and output messages.
operation – Definition of how input and output messages are associated with a logical operation.
portType – Groups a set of operations together.
binding – Specification of which protocols that are used for message exchange for a particular portType.
port – Specifies an address for a binding.
service – Used to group a set of related ports.
