消息代理节点如果不可靠，将直接影响到消息的传递。
为了提高查询效率，该文提出一种基于代理节点的查询机制。
Aiming at improving search efficiency, this paper proposes a search mechanism with multiple small-scale floods initiated by proxy peers for a query.
然而假设所有的代理节点全连接的话会导致路由信息分发不可扩展。
However, to assume full connectivity among all proxy nodes makes routing information distribution non-scalable.
移动客户可以在不同的地域与不同的事件代理节点连接和可靠接收消息。
Thus, mobile clients can reliably receive messages in different areas and event brokers.
管理代理拓扑由位于单个系统上的一个管理代理节点和一个或多个应用程序服务器节点构成(图2)。
The administrative agent topology is built from an administrative agent node and one or more application server nodes on a single system (Figure 2).
控制中心负责实时监控整个无线网络的安全情况，对代理节点检测到的可疑行为作进一步判断后确定性质，并控制代理节点对入侵行为做出适当的响应。
The control center is responsible to monitor the WLAN security in real time, identifies the threats detected by agents and makes agent respond properly against the threats.
每个模式都应用于代理的一个节点。
启动定制节点和代理服务器。
这包括部署管理器、节点代理和应用服务器。
This includes the deployment manager, node agents, and application servers.
每个节点都通过代理与部署管理器通信。
Each node USES an agent to communicate with the deployment manager.
注意最好选择应用服务器而不是系统服务器，例如节点代理或是域管理器。
Be careful to select an application server rather than a system server, such as the node agent or domain manager.
您将需要重新启动部署管理器、节点代理和您的应用服务器，以便使更改生效。
You will need to restart the deployment manager, node agents, and your application servers for these changes to take affect.
首先，节点代理是计算单元的一个全功能成员，因此它有完全的管理权限。
First, a node agent is a fully functional member of the cell and thus has full administrative authority.
所有与新部署管理器连接的节点代理都必须与旧版部署管理器同步。
All node agents that connected to the new deployment manager must synchronize with the old release deployment manager.
首先创建启动和停止节点代理和应用服务器进程的两个脚本。
First, create a couple of scripts to start and stop the node agent and the application server processes.
节点代理是计算单元的一个全功能成员，它有完整的管理权限。
A node agent is a fully functional member of the cell and has full administrative authority.
部署管理器使用文件传输协议向节点代理发送配置更新。
The deployment manager communicates configuration updates to the node agents using the file transfer protocol.
同样，也将节点代理中的所有通知发送到部署管理器。
In the same way, all notifications in the node agent are sent to the deployment manager.
为了测试数据源，对应节点代理需要启动并运行。
To Test the data source the corresponding node agent needs to be up and running.
这个基础设施包含一些节点代理和一个部署管理器节点，后者充当这些集群所属的整个单元的管理中心点。
This infrastructure consists of node agents and a deployment manager node as the central point of administration of the entire cell that these clusters belong to.
部署管理器将通过这些视图调用的操作传达至相应应用程序服务器节点的节点代理。
Actions invoked through these views are communicated by the deployment manager to the node agent of the corresponding application server node.
这是使用任何代理转换节点来完成的。
从管理代理取消注册节点时，该节点将保留所有配置更改。
When a node is deregistered from the administrative agent, it retains all configuration changes.
此时还将启动节点代理。
记住，这个步骤要成功，节点代理进程必须启动并运行。
Keep in mind that the node agent processes must be up and running for this step to be successful.
考虑到节点代理在应用服务器启动自检中扮演的角色，您不希望节点代理长时间不可用。
Given the role the node agent plays in bootstrapping application servers, you wouldn't want a node agent to be unavailable for an extended period of time.
所有运行中的节点代理将自动完成同步。
当节点代理不可用时，管理员无法调用该节点的任何操作。
When the node agent is unavailable, administrators are unable to invoke any operations for that node.
当配置已得到成功更新后，迁移工具将禁用以前版本的节点代理。
The migration tooling will disable the prior release's nodeagent when the configuration has been successfully updated.
第一个选项要求您停止并重启所有节点代理，以清除节点代理JVM中的“陈旧”缓存，这些缓存指向服务器的旧IP地址。
The first option requires you to stop and restart all the node agents in order to clear the "stale" cache in the node agent JVM that points to the old IP address for the server.
