摘要： Systems and methods that supply a global knowledge on what nodes are available in the system, via employing routing tokens that are analyzed by a centralized management component to infer status for the nodes. When nodes fail, the routing tokens associated therewith are acquired by neighboring nodes, and the global knowledge updated. Moreover, upon inferring a failed or down status for a node, a challenge can be sent to a node reporting such failure to verify actual failure(s).

摘要： Systems and methods that ensure formation of a single ring from a seed node at any given time. A “bootstrap” phase is included in a node's life cycle, to mitigate adverse affects of split-brain conditions in a network. During such bootstrap phase, if an existing ring is found, the seed node can join the existing ring in a same manner as a non-seed node does. If no ring is detected, the bootstrap phase attempts to elect a seed node to be the “super-seed node”, wherein a new ring can then be formed with such new super-seed node as the first node.

摘要： Systems and methods that provide for assignment and recovery of tokens as part of a plurality of nodes and distributed application framework/network. The assignment component assigns numbers and tasks to candidates and facilitates multiple leader election. Moreover, a recovery component can recover a token for a node that leaves the network (e.g., crashes). Such recovery component ensures consistency, wherein only one server is assigned recovery of the token and associated tasks.

摘要： Systems and methods that restore a failed reconfiguration of nodes in a distributed environment. By analyzing reports from read/write quorums of nodes associated with a configuration, automatic recovery for data partitions can be facilitated. Moreover, a configuration manager component tracks current configurations for replication units and determines whether a reconfiguration is required (e.g., due to node failures, node recovery, replica additions/deletions, replica moves, or replica role changes, and the like.) Reconfigurations of data activated as being replicated from an old configuration to being replicated on a new configuration may be performed in a transactionally consistent manner based on dynamic quorums associated with the new configuration and the old configuration.

摘要： Architecture that provides reliable communications of broadcast data (e.g., a message) in a collection of nodes. Each node in the collection is assigned a range of identifiers in a token. The union of the tokens for all nodes is the entire identifier range space. Each node that receives a reliable broadcast message from an originator node acknowledges receipt of the message using its token. One or more intermediate nodes forward the message from the originator node to other nodes with which the originator node has no direct communications (multi-level node structure). The indirect nodes each send acknowledgements back to the parent nodes (which can be an intermediate node) which combine the tokens to ensure the entire range space for the associated assigned token range is covered. The originator node ultimately receives tokens to compute if all nodes have received the message.
摘要翻译： 在节点集合中提供广播数据（例如，消息）的可靠通信的架构。 集合中的每个节点都会在令牌中分配一系列标识符。 所有节点的令牌的并集是整个标识符范围空间。 从始发者节点接收可靠的广播消息的每个节点使用其令牌来确认消息的接收。 一个或多个中间节点将消息从发起方节点转发到与发起者节点没有直接通信的其他节点（多级节点结构）。 间接节点每个发送确认返回给组合令牌的父节点（可以是中间节点），以确保相关分配的令牌范围的整个范围空间被覆盖。 发起者节点最终接收令牌以计算所有节点是否已经接收到消息。

摘要： Systems and methods for managing configurations of data nodes in a distributed environment A configuration manager is implemented as a set of distributed master nodes that may use quorum-based processing to enable reliable identification of master nodes storing current configuration information, even if some of the master nodes fail. If a quorum of master nodes cannot be achieved or some other event occurs that precludes identification of current configuration information, the configuration manager may be rebuilt by analyzing reports from read/write quorums of nodes associated with a configuration, allowing automatic recovery of data partitions.
