摘要： A scalable, distributed, highly available, load balancing server system having multiple machines is provided that functions as a front server layer between a network (such as the Internet) and a back-end server layer having multiple machines functioning as Web file servers, FTP servers, or other application servers. The front layer machines comprise a server cluster that performs fail-over and dynamic load balancing for both server layers. The operation of the servers on both layers is monitored, and when a server failure at either layer is detected, the system automatically shifts network traffic from the failed machine to one or more operational machines, reconfiguring front-layer servers as needed without interrupting operation of the server system. The server system automatically accommodates additional machines in the server cluster, without service interruption. The system operates with a dynamic reconfiguration protocol that permits reassignment of network addresses to the front layer machines. The front layer machines perform their operations without breaking network communications between clients and servers, and without rebooting of computers.

摘要： A distributed gateway (310) represented in the figure for controlling computer network data traffic dynamically reconfigures traffic assignments among multiple gateway machines (302, 304, 306, 308) for increased network availability. If one of the distributed gateway machines becomes unavailable, traffic assignments are moved among the multiple machines such that network availability is substantially unchanged. The machines of the distributed gateway form a cluster (310) and communicate with each other using a Group Membership protocol word such that automatic, dynamic traffic assignment reconfiguration occurs in response to machines being added and deleted from the cluster, with no loss in functionality for the gateway overall, in a process that is transparent to network users, thereby providing a distributed gateway functionality that is scalable. Operation of the distributed gateway remains consistent as machines are added and deleted from the cluster. A scalable, distributed, highly available, load balancing network gateway is thereby provided, having multiple machines that function as a front server layer (310) between the network (314) and a back-end server layer (316,318) having multiple machines functioning as Web file servers, FTP servers, or other application servers. The front layer machines (302,304,306,308) comprise a server cluster that performs fail-over and dynamic load balancing for both server layers.
摘要翻译：用于控制计算机网络数据业务的图中所示的分布式网关（310）在多个网关机器（302,304,306,308）之间动态地重新配置业务分配，以增加网络可用性。如果分布式网关机器之一变得不可用，则在多个机器之间移动流量分配，使得网络可用性基本上不变。分布式网关的机器形成集群（310）并且使用组成员协议字彼此通信，使得响应于从集群添加和删除的机器而发生自动的动态业务分配重新配置，而没有功能损失网关在一个对网络用户透明的过程中，从而提供可扩展的分布式网关功能。分布式网关的操作保持一致，因为从集群中添加和删除机器。由此提供了可扩展的，分布式的，高度可用的负载平衡网络网关，其具有用作网络（314）和具有多个机器的后端服务器层（316,318）之间的前端服务器层（310）的多个机器 Web文件服务器，FTP服务器或其他应用程序服务器。前层机器（302,304,306,308）包括为两个服务器层执行故障切换和动态负载平衡的服务器集群。
