    • A method (400) and system (100) for a wireless multi-hopping communication system is provided, wherein the system (100) includes an access point (102), a source node (CR1), and a plurality of nodes. The source node (CR1) is in communication with the access point (102), and configured to transmit a signal on at least one of a plurality of frequencies. The plurality of nodes are in communication with the access point (102) and the source node (CR1), and configured to transmit a signal on at least one of the plurality of frequencies, wherein the source node (CR1) and the plurality of nodes are adapted to determine a routing path utilizing at least one intermediate node (CR2) of the plurality of nodes and a transmitting frequency of the plurality of frequencies while reducing interference to a primary user of the transmitting frequency.

    • A cluster recovery and maintenance system, method and computer program product for use in a server cluster having plural nodes implementing a server tier in a client-server computing architecture. A first group of N active nodes each run a software stack comprising a cluster management tier and a cluster application tier that actively provides services on behalf of one or more client applications running in a client application tier on the clients. A second group of M spare nodes each run a software stack comprising a cluster management tier and a cluster application tier that does not actively provide services on behalf of client applications. First and second zones in the cluster are determined in response to an active node membership change involving one or more active nodes departing from or being added to the first group as a result of an active node failing or becoming unreachable or as a result of a maintenance operation involving an active node. The first zone is a fault tolerant zone comprising all active nodes that remain operational. The second zone is a fault containment zone comprising all active nodes participating in the membership change and at least a corresponding number of spare nodes to the extent that the membership change involves a node departure. During recovery and maintenance, fast recovery/maintenance and high application availability are implemented in the fault containment zone, while continuous application availability is maintained in the fault tolerant zone.
    • 一种用于服务器集群的集群恢复和维护系统,方法和计算机程序产品,其具有在客户端 - 服务器计算体系结构中实现服务器层的多个节点。 第一组N个活动节点每个运行包括集群管理层和集群应用层的软件堆栈,该集群应用层主动地代表在客户端上的客户端应用层中运行的一个或多个客户端应用程序提供服务。 第二组M个备用节点每个运行一个包含集群管理层的软件堆栈和不代表客户端应用程序主动提供服务的集群应用程序层。 集群中的第一和第二区域是响应于主动节点隶属关系变化而被确定的,该主动节点隶属关系改变是由于主动节点故障或变得不可达或作为维护的结果而离开或被添加到第一组的一个或多个活动节点 涉及主动节点的操作。 第一个区域是包含所有活动节点的容错区域,它们保持运行。 第二区域是包括参与成员资格变更的所有活动节点和至少相应数量的备用节点的故障容纳区域,以使得成员资格变化涉及节点离开的程度。 在恢复和维护期间,在故障控制区域中实现快速恢复/维护和高应用程序可用性,同时在容错区域中保持连续的应用程序可用性。

    • An apparatus, system, and method are provided for verified fencing of a rogue node within a cluster. The apparatus may include an identification module, a shutdown module, and a confirmation module. The identification module detects a cluster partition and identifies a rogue node with a cluster. The shutdown module sends a shutdown message to the rogue node using a message repository shared by the rogue node and the cluster. The shutdown message may optionally permit the rogue node to preserve latent I/O data prior to shutting down. The confirmation module receives a shutdown ACK from the rogue node 206. Preferably, the shutdown ACK is sent just prior to the rogue node actually shutting down.
    • 提供了一种装置,系统和方法,用于验证群集内的流氓节点的防护。 该装置可以包括识别模块,关机模块和确认模块。 识别模块检测集群分区并识别具有集群的流氓节点。 关闭模块使用由流氓节点和群集共享的消息存储库向无效节点发送关闭消息。 关闭消息可以可选地允许流氓节点在关闭之前保留潜在I / O数据。 确认模块从流氓节点206接收关闭ACK。 优选地,在流氓节点实际上关闭之前发送关闭ACK。
