看到 locality-based least-[url=http://whatis.ctocio.com.cn/searchwhatis/393/5947393.shtml]connection[/url] with replication (LBLCR) 算法的英文是：
The locality-based least-connection with replication (LBLCR) scheduling [url=http://whatis.ctocio.com.cn/searchwhatis/146/6025146.shtml]algorithm[/url] is also for destination [url=http://whatis.ctocio.com.cn/searchwhatis/191/6025691.shtml]IP[/url] load balancing. It only differs from the locality-based least-connection (LBLC) scheduling as follows: the load balancer maintains mappings from a target to a [url=http://whatis.ctocio.com.cn/searchwhatis/23/5949023.shtml]set[/url] of [url=http://whatis.ctocio.com.cn/searchwhatis/497/5948997.shtml]server[/url] nodes that can serve the target. Requests for a target are assigned to the least-connection [url=http://whatis.ctocio.com.cn/searchwhatis/443/6093443.shtml]node[/url] in the target's server set. If all the node in the server set are over loaded, it picks up a least-connection node in the [url=http://whatis.ctocio.com.cn/searchwhatis/247/5947247.shtml]cluster[/url] and adds it in the sever set for the target. If the server set has not been modified for the specified [url=http://whatis.ctocio.com.cn/searchwhatis/216/6092716.shtml]time[/url], the most loaded node is removed from the server set, in order to avoid high degree of replication.

请教一下：
其中的[url=http://server.ctocio.com.cn/]服务器[/url]组（英文资料中的target）和[url=http://server.ctocio.com.cn/server_tech/tt_server_hpc/]集群[/url]（cluster）之间是什么关系？

服务器组和集群

我的理解是：服务器组是动态组成服务器，而这些个服务器均是集群中的一个。
