设备代理的主要任务是处理作业。
与硬件设备交互的代理通常称为设备代理。
Agents that interact with hardware devices are commonly referred to as device agents.
为了创建新设备代理，将需要实现两个主要功能。
To create a new device agent you would need to implement two primary functions.
社区名相当于用户名，用于从托管设备代理访问信息。
The community name is equivalent to a user name that is used to access information from the managed devices agent.
为兼容llrp的RFID读取器提供LLRP设备代理。
客户端的设备代理读取作业队列，并且启动处理所有等候执行的作业。
The device agent on the client reads the job queue and starts processing all waiting jobs.
设备代理从关联硬件捕获或接收到数据时，会将数据作为事件消息发布。
When the device agent captures or receives data from its associated hardware, it publishes the data as an event message.
一种方法是通过创建新DataCapture设备代理进行。
One way is through the creation of new Data Capture device agents.
另外一些则主要在批发和零售行业，包括汽车和农业设备代理、金属服务中心以及废品站。
Yet another group involves wholesale and retail establishments. These would include auto and agricultural equipment dealerships, metal service centers, and scrap yards.
确保安装了EveryplaceAccess客户端，并且检验设备代理能否同设备管理器服务器通信。
Ensure that the Everyplace Access client is installed and verify that the device agent can communicate with the device Manager server.
例如，设备代理可能会在捕获或接收数据时发布事件消息，指示已经触发了动作传感器或已经读取了RFID标签。
For example, a device agent might publish an event message whenever it captures or receives data indicating a motion sensor has been triggered or that an RFID tag has been read.
数据捕捉设备代理将通过Bluetooth、u SB、TCP或其他用于捕捉数据的协议与这些设备进行交互。
Data capture device agents would interface with these devices via Bluetooth, USB, TCP, or some other protocol to capture the data.
硬件设备代理层实现了同小区内智能网关设备的通信协议SGMP ，同时完成了对服务层接口的调用；
The hardware equipments layer implement the communication protocol—SGMP with the intelligent gateway equipments in the residence, and accomplish the application of interface of the service layer.
如果是新传感器设备类型，或者事件消息是现有传感器设备类型的新事件，则设备代理将发布自定义事件消息。
If it's a new sensor device type, or if the event message represents a new event for an existing sensor device type, the device agent would publish a custom event message.
通过设备管理器服务器上的插件(servlet)与Windows客户端系统上的设备代理之间传递信息来管理设备。
Devices are managed by the communication between the plug-in (a servlet) that resides on the device Manager server and the device agent on the Windows client system.
设备代理可以在轮流检测的间隔或设备启动后的任何时刻(或两种条件同时满足)查询等待执行的作业，这依赖于所处的环境。
Depending on the environment, the device agent may poll for waiting jobs at a polling interval, or whenever the device is powered on, or both.
创建设备代理的一个备选方法是，直接使用EventGateway将CBE事件发送到PremisesServer。
An alternative to creating device agents is to send CBE events directly to the Premises Server using the event Gateway.
单击SendMeasurement按钮以将事件数据发送给DataCapture andDelivery设备代理，并启动处理流程。
Click the send Measurement button to send the event data to the data Capture and Delivery device agent and start the processing.
这些代理使用设备的本机协议与硬件设备通信。
These agents communicate with hardware devices using the device’s native protocol.
这些工具通过UDP使用SNMP来为SNMP代理轮询设备和应用程序指标。
These tools use SNMP over UDP to poll an SNMP agent for device and application metrics.
管理软件还会收到来自代理的通知警告，以响应设备中发生的特定事件。
The management software may also receive notification alerts from the agent in response to particular events happening on the device.
您可以通过配置设备来配置用户代理。
You can configure the user agent via configuration settings.
第一层负责发现活动网络，轮询服务和设备是否出故障，以及截获或处理来自设备、服务或更高层分布式代理的异步事件。
It is responsible for active network discovery, polling for device outages and services, and intercepting or processing asynchronous events from devices, services, or higher level distributed agents.
首先，代理将需要与硬件设备通信，以捕获所需数据。
First, the agent would need to communicate with the hardware device to capture the required data.
为做到这一点，需创建一个对象(或代理)来代表设备。
To do this, an object (or surrogate) is created to act on behalf of the device.
设备类型独立性：代理体系结构必须能够支持广泛的具有不同能力的硬件和软件组件。
Device type independence: The surrogate architecture must be able to support a wide range of hardware and software components with different capabilities.
最后，系统管理产品、代理和设备支持对运行时和它们托管的编程模型构件的管理。
Finally, systems management products, agents, and instrumentation support the administration of the runtimes and the programming model artifacts they host.
当在同一个会话中切换用户代理时，MCS缓存设备信息会导致错误行为。
The MCS caches device information, which can result in erroneous behavior if the user-agent is swapped during the same session.
当在同一个会话中切换用户代理时，MCS缓存设备信息会导致错误行为。
The MCS caches device information, which can result in erroneous behavior if the user-agent is swapped during the same session.
