摘要： A method for maintaining a current view of a cluster's membership comprising the steps of maintaining a list of member nodes and updating the list when a modification thereto is noticed by a first node by receiving a first update message from the first node in a second node, thereafter, sending a second update message from the second node to a third node to propagate the modification and sending to the first node a first confirm message from the second or the third node. A node member of a cluster capable of maintaining a first list of neighboring nodes, maintaining a second list of neighboring nodes sharing a current view therewith and ensuring that the first list matches the second by exchanging messages with neighboring nodes, wherein each message comprises topology information. Upon confirmation that both lists match, the node being capable of sending a confirmation message toward neighboring nodes.
摘要翻译：一种用于维护群集成员的当前视图的方法，包括以下步骤：通过从第一节点的第一节点接收第一更新消息，维护成员节点的列表，并且当第一节点对其进行修改时，更新列表，此后，将第二更新消息从第二节点发送到第三节点，以传播修改，并向第一节点发送来自第二节点或第三节点的第一确认消息。能够维护相邻节点的第一列表的集群的节点成员，维护与其共享当前视图的相邻节点的第二列表，并且通过与相邻节点交换消息来确保第一列表与第二列表匹配，其中每个消息包括拓扑信息。在确认两个列表匹配时，节点能够向邻近节点发送确认消息。

摘要： A node member of a cluster in a network comprising a plurality of nodes and a method related to the capabilities of the node, which is capable of maintaining a stable view of the cluster's membership, maintaining a list of neighboring nodes sharing a same updated view of the cluster's membership and receiving a confirmation message from a second node confirming that a new view received therein should replace the stable view and become a new stable view. The node is further capable of verifying that the new view is up to date in comparison to the same view and, if the new view is not up to date, discarding the confirmation message.

摘要： A method and communication node for providing secure communications and services in a High Availability (HA) cluster. The communication node comprises an Operating System (OS) that detects an unavailability of a first service application process and switches a second service application process from the first state to the second state, the second service application being selected for taking over service currently provided from the first service application process, the first state and the second state each being associated to a set of rights in the cluster. The OS generates a private key for the second service application process based on its second state. The set of rights associated to the second state allows the OS to replace the first service application process with the second service application process for providing secure communications between the second service application and other service application processes in the HA cluster.

摘要： A regular expression matching hardware implementation comprises two tightly coupled hardware engines. A regex engine performs state transitions and accepts (as matching) or rejects (as not matching) an input string. The regex engine takes also care of the logic of the operators and deals with the complexity of the state machine. A lookup engine reads characters from an input (e.g., tape, memory, network packets, or the like), and provides them to the regex engine. A preprocessing procedure transforms a regular expression into a regex state transition table and a lookup table, for use by the regex engine and lookup engine, respectively. The two hardware engines are synchronized by a global state machine. The regex engine advances the state machine, and the lookup engine reads it.

摘要： Method and nodes are provided for propagating between the nodes information about processing capacity of peer nodes. Two types of signals are sent from propagating nodes towards their peer nodes. A propagating node sends first signal type at a constant rate and a second signal type at a variable rate. A ratio of the rates calculated at a peer node represents the processing capacity available a propagating node. Sequence numbers may be added to signals of the first and second type in order to assist peer nodes in detecting capacity issues.

摘要： Methods, a data source and a router are provided to fragment packets that are to be sent in multicast mode towards a plurality of destinations comprised in a multicast group. Each router along a path leading from the data source towards some of the destinations sends its maximum transmission unit value in an uplink direction. Each router directly connected to the data source calculates a lowest maximum transmission unit based on various maximum transmission unit values received from downstream routers. The data source receives from each of the directly connected routers a maximum transmission unit value, which is certain to be acceptable to all routers and destinations of the multicast group downstream of that directly connected router. The data source selects a lowest one of the received maximum transmission unit values and fragments data contents accordingly.

摘要： Software, systems and methods are described which provide cache management capabilities. The number of cache sets to be used in each partition of the cache memory space is based on a number of cache pages in each partition and an associativity level associated with the set associative cache. The cache sets can be numbered based on the partition number, a total number of partitions and a cache page index. Cache management according to these exemplary embodiments reduces problems associated with cache trashing in multiprocessor environments sharing common data structures in set associative caches.
