摘要： Communication between clusters of processing nodes is initiated by designating a link layer address and a target node name in a remote cluster. The link layer address is transmitted to the target node via a regular network transmission. The link layer address is stored locally in each cluster and the nodes in each cluster are signaled that a configuration change has been made, so that gateway nodes in the clusters can obtain the link layer address to use for subsequent communications with the other cluster, such as event notifications of node status changes.

摘要： A gossiping scheme for sharing node status in a cluster of nodes provides a robust mechanism for determining node status within the cluster. Nodes transmit gossip messages to each other nodes, the gossip messages listing other nodes in the cluster that are operational. When a node does not receive a gossip message from a particular node within a predetermined time period, then the node transmits messages to the other nodes indicating that the particular node is down. However, if another node has received a packet from the particular node within the predetermined time period and receives the node down message, then the other node responds with a node alive message.
摘要翻译：用于在节点集群中共享节点状态的八卦方案为确定集群内的节点状态提供了一种可靠的机制。节点向每个其他节点发送八卦消息，八卦消息列出了群集中其他可操作的节点。当节点在预定时间段内没有从特定节点接收到八卦消息时，节点向其他节点发送指示特定节点关闭的消息。然而，如果另一节点在预定时间段内已经从特定节点接收到分组并且接收到节点向下消息，则另一个节点用节点存活消息进行响应。

摘要： Provided are techniques related generally to computer communication and, more specifically, to techniques that provide legacy applications with access to a cluster infrastructure. A pseudo interface layer provides applications with internet protocol (IP) family sockets access to cluster awareness protocols in a manner that may be transparent to both the application and the cluster awareness layer of a kernel.

摘要： Communication ability between nodes in a cluster-based computer system is tracked to inform applications executing on the nodes of the existence and quality of the endpoint-to-endpoint communications available between the nodes. Communications between a node and other nodes are tracked, and a database records the communication ability between the node and the other nodes for each link between the nodes. The tracking and recording are repeated at the other nodes. A registration by an application executing at a particular one of the nodes to receive notifications of changes in the communication ability with another node over a particular link (or in general) will cause notification of the application when the link status changes.

摘要： According to a method of access to a shared data record subject to contemporaneous read and write access by multiple requesters, a requester reads a shared data record including a payload and a first checksum. The requester calculates a second checksum of the payload of the data record. If the first and second checksums are not equal, the requester again reads the shared data record, including a third checksum, and calculates a fourth checksum of the payload of the shared data record. If the third and fourth checksums are equal, the requester processes the shared data record as valid, and if the second and fourth checksums are equal, the requester handles the shared data record as corrupt.

摘要： A method and apparatus for data security for a distributed file system. A distributed file system interface is coupled to the one or more client applications, and a storage server and a meta-data server are coupled to the distributed file system interface. The meta-data server receives open-file requests from the distributed file system interface and in response creates a security object. The meta-data server also generates an partial encryption key and stores the partial encryption key in the security object. The block storage server completes the encryption key, and the meta-data server encrypts the list of blocks that are in the file and stores the encrypted block list in the security object. The security object is then returned to the distributed file interface and used in subsequent file access requests.

摘要： A data processing system and a method implement a unique push, or streaming, model for communicating time sensitive encoded data, such as video and audio data, in a communication network. A pacing mechanism is implemented in the data processing system to allow a client to pace a streaming server in a stable way such that a fill level of a client buffer will oscillate around a single threshold value. A simple protocol is implemented to protect pacing primitives, allow recovery for pacing primitives, and to keep a client and a server synchronized during the pacing operation. To implement the pacing mechanism, the streaming server transmits data at a slightly faster rate than it was encoded. Subsequently, a decoder circuit at the client, or receiver, uses the transmitted data at the encoded rate. Thus, the utilization of buffers in the client will gradually increase. When the utilization of buffers reaches a threshold level, the client provides a pacing message to the server. When the pacing message is received, the server withholds sending data for a period of time sufficient to drop the client buffer utilization to a level below a threshold level.

摘要： An event notification system for distributed processing systems provides for replacement of event identifiers associated with transient objects, such as processes within the processing system. An event management interface receives a notification from an event producer that an identifier of an event produced by the event producer is no longer valid. The event management interface blocks event notification for the event and dissociates an event registration entry associated with the event from the event identifier. A new event identifier is received from the event producer by the event management interface, which associates the registration entry with the new event identifier. Event notification for the event is then resumed.
