    • A load-balancing cluster includes a switch having a plurality of ports; and a plurality of servers connected to at least some of the plurality of ports of the switch. Each server is addressable by the same virtual Internet Protocol (VIP) address. Each server in the cluster has a mechanism constructed and adapted to respond to connection requests at the VIP by selecting one of the plurality of servers to handle that connection, wherein the selecting is based, at least in part, on a given function of information used to request the connection; and a firewall mechanism constructed and adapted to accept all requests for the VIP address for a particular connection only on the server that has been selected to handle that particular connection. The selected server determines whether it is responsible for the request and may hand it off to another cluster member.
    • 负载均衡集群包括具有多个端口的交换机; 以及连接到交换机的多个端口中的至少一些端口的多个服务器。 每个服务器可由相同的虚拟互联网协议(VIP)地址寻址。 集群中的每个服务器具有构造并适于通过选择多个服务器中的一个来处理该连接来响应VIP处的连接请求的机制,其中,所述选择至少部分地基于所使用的信息的给定功能 请求连接; 以及防火墙机制,其构造和适于仅在已经被选择来处理该特定连接的服务器上接受针对特定连接的VIP地址的所有请求。 所选择的服务器确定它是否对请求负责,并将其移交给另一个集群成员。

    • A load-balancing cluster includes a switch having ports; and servers connected to at least some of the ports. The servers are each addressable by the same virtual Internet Protocol (VIP) address. A first server of the plurality of servers establishing a Transmission Control Protocol (TCP) connection with a client computer, and, in response to a resource request received by the first server from the client computer for a particular resource, if the first server does not have a copy of the particular resource it queries one or more peers regarding the particular resource. Based at least in part on responses from the peers, the first server either: obtains the particular resource from a peer; or migrates the TCP connection to a peer; or serves the particular resource to the client request through a second server.
