进行这一操作最常用的设备是一个负载均衡器，这是一个从外部接收请求并将它们移交给下一个可用应用程序服务器的装置。
The device most often used to do this is a load balancer, which is an appliance that accepts requests from the outside world and hands them off to the next available application server.
通常，在集群的情况下，会话状态保存在集群中的一台计算机上，并且负载均衡器总是把用户的请求重定向到保存他(或她)的会话的机器上。
Often, in a clustered situation, session state is kept on one computer in the cluster, and the load balancer always directs requests from a user to the machine that is storing his or her session.
如果由于维护或者升级的原因需要移除一个单元，负载均衡器可以把流量直接发送到正在运行的那个单元。
If a cell needs to be removed for maintenance or an upgrade, the load balancer can be directed to send traffic to just the cell that is running.
请求进入负载均衡器，然后被转发到池中一个可用的服务器中。
Requests come in to the load balancer and are directed to an available server in the pool.
请求被转发到集群主机，该集群主机名称映射到负载均衡器。
The request is forwarded to the cluster host name that is mapped to the Load Balancer.
最后，浏览您的负载均衡器的DNS名称。
启用(激活)负载均衡器的配置。
禁用(使无效)负载均衡器的配置。
Disable (make inactive) a configuration at the load balancer.
更新负载均衡器中的规则来切断这些名称，并关联合适的后端服务器。
The rules at the load balancer are then updated to key off these names and associate the proper back-end servers.
负载均衡器使用的是一种即时的方法，它会基于集群中各节点的当前负载来选择主副本和二级副本的位置。
The load balancer uses a just in time methodology by selecting the location of the primary and secondary replicas of a new database based on current load on nodes within a cluster.
集群前端是一个软件HTTP负载均衡器。
负载均衡器可以使用命令行、脚本、GUI或者配置向导来进行配置。
The Load Balancer can be configured by using either a command line, scripts, the GUI, or a configuration wizard.
这个部署脚本已经写好：您所需要的就是启动服务器，并将它添加到负载均衡器上。
The deployment scripts are already written: All you need to do is start the server and add it to the load balancer.
并置负载均衡器的服务器地址要与NFA、集群服务器地址以及返回地址相分离。
The address for the server that is collocated with the Load Balancer should be separate from the NFA, the cluster server address, and the Return address.
客户端网关是一个作为路由地址使用的IP 地址，通过它使返回的业务流从负载均衡器向前传送到客户端。
The client gateway is an IP address that is used as the router address through which traffic in the return direction is forwarded from the Load Balancer to clients.
有关先决条件和安装指南的详细信息，请参阅负载均衡器管理指南。
See the Load Balancer Administration Guide for requirements and installation instructions.
在负载均衡器(使用以太网卡0)上配置一个别名返回地址。
Configure an alias return address on Load Balancer (using Ethernet card 0).
然后配置搜索Portlet以与负载均衡器进行通信。
Then configure the search portlets to communicate with the load balancer.
图1显示了一个在本地内容主机上并置负载均衡器的配置实例，一般而言。
Figure 1 shows a sample configuration that collocates Load Balancer on a local content host. In general.
应用程序不断地改进，以利用Amazon EC2所提供的功能，从加载新服务器到加载均衡器。
Improvements were made incrementally to take advantage of the Amazon EC2 offerings, from launching new servers to load balancers.
清单7显示了两个命令，第一个命令elb - create - lb，创建负载均衡器。
Listing 7 shows two commands. The first command, elb-create-lb, creates the load balancer.
Server2完成请求后，将会把应答返还到返回地址(192.168.206.131)，然后负载均衡器将应答重定向到起始的客户端。
When Server 2 has completed the request, it will return the response to the return address (192.168.206.131). Load Balancer will then redirect the response to the original client.
InService意味着服务器能够通过负载均衡器处理请求。
InService means that the service is able to handle requests through the load balancer.
如无缝播放 ，五波段均衡器，创建动态播放列表以及FLAC /OGG格式支持，这些功能，即使现在的很多MP3还都是望尘莫及的。
Things like gapless playback, 5-band equalizers, on-the-fly playlist creation and FLAC/OGG support are features that many of today's models can only envy.
一开始是前端有一个负载均衡器的面向Web的集群实例。
We start with clustered web-facing instances fronted with a load balancer.
carp(4)负载均衡器的配置已经过简化。
The configuration of the carp (4) load balancer has been simplified.

基于AWS使用多可用性区域、DB错误恢复与负载均衡器搭建了一个网站。
Built a reliable website on AWS using multiple availability zones, DB failover, and load balancers.
在本实例中，目的主机是Server2，包的目的地址将是192.168.194.13，资源地址将是192.168.206.131，资源地址是负载均衡器的返回地址。
In the case where the destination is Server 2, the destination of the packet will be 192.168.194.13, and the source will be 192.168.206.131, which is the return address of the Load Balancer.
在不同的节点上配置两个相同的远程搜索服务器，让搜索管理Portlet指向它们，并配置一个用来在两者间均衡请求的负载均衡器。
Configure two identical remote search servers on different nodes, point the search administration portlet to each of them, and configure a load balancer to balance requests between them.
