Lync Server 2013 中的扩展控制器池-DNS 负载平衡和硬件负载平衡器Scaled Director pool - DNS load balancing and hardware load balancer in Lync Server 2013

一个扩展的控制器池,在其中部署了多个控制器以处理更多容量并提供高可用性时,需要使用负载平衡将客户端和服务器通信分发到池的所有成员。A scaled Director pool, where there are more than one Director deployed to handle additional capacity and to provide high availability, requires load balancing to distribute client and server communication to all members of the pool. 控制器承载 web 服务的方式与前端池非常相似。A Director hosts web services much like a Front End pool. 若要提供负载平衡,可以使用硬件负载平衡或域名系统 (DNS) 负载平衡和硬件负载平衡。To provide the load balancing, you can use either hardware load balancing or domain name system (DNS) load balancing and hardware load balancing. Web 服务需要硬件负载平衡,单独的 DNS 负载平衡无法提供 Web 服务所需的功能。Hardware load balancing is required for the web services, and DNS load balancing alone does not provide the capabilities required for the web services.

以下主题介绍了在结合使用 DNS 负载平衡和硬件负载平衡时部署控制器池的规划注意事项。The following topics describe the planning considerations for deploying a Director pool using DNS load balancing in conjunction with hardware load balancing. 如果打算使用硬件负载平衡,但不是控制器池的 DNS 负载平衡,请参阅 Lync Server 2013 中的主题扩展的控制器池-硬件负载平衡器 ,用于描述该拓扑的规划要求。If you intend to use hardware load balancing, but not DNS load balancing for the Director pool, see the topic Scaled Director pool - hardware load balancer in Lync Server 2013 that describes the planning requirements for that topology.
