摘要： The present invention extends to methods, systems, and computer program products for allocating and reclaiming resources within a rendezvous federation. Embodiments of the invention include formulating and routing messages in accordance with cached two-way agreements between adjacent nodes on a ring of nodes. Cached two-way agreements divide responsibility for at least unoccupied identifiers between the adjacent nodes on a ring. When a message is received at a node, the node can refer to a cached two-way agreement to determine if it or an adjacent node is responsible for the message. The node then sends the message to the next appropriate component in accordance with the cached two-way agreement.

摘要： The present invention extends to methods, systems, and computer program products for facilitating inter-proximity communication within a rendezvous federation. Nodes maintain collateral ring set entry tables that include collateral rings and corresponding entry nodes into the collateral rings. Nodes can exchange collateral ring set entry state to update one another on the configuration of rings within a tree of rings. Nodes can refer to collateral ring set entry tables, as well as to other nodes, to identify entry nodes into rings that are collateral rings of the node. Messages can be sent to entry nodes in collateral rings. A message can include an indication that an entry node in a target proximity ring is to resolve the message to the node in the target proximity ring which has a node ID closest to an indicated destination node.

摘要： The present invention extends to methods, systems, and computer program products for appropriately detecting node failures in a rendezvous federation. A monitor node monitors a subject node. The subject node intermittently renews a time-to-live duration value with the monitor node to indicate the monitor node that the subject node has not failed. In some embodiments, each node in a pair of nodes monitors the other nodes in the pair of nodes. Thus, each node is a subject node and a monitor node. In further embodiments, an arbitration facility arbitrates failure reports.

摘要： The present invention extends to methods, systems, and computer program products for broadcasting communication within a rendezvous federation. Embodiments of the invention include inter-ring and intra-ring communication. Inter-ring communication includes sending a message to destination rings included in a node's Collateral Ring Set entry table. When a node identifies a destination ring that has not yet received a message, the node can send a ring notification message. The ring notification message propagates towards a publishing node until a responsible node in the message path to the publishing node is identified. The responsible node updates its entry table to include the ring and forwards the message to the destination ring. Intra-ring communication can include recursively partitioning ranges of nodes within a ring and forwarding the message to nodes included the partitioned ranges.

摘要： A computational system determines that a joining node in the federation infrastructure desires to join an identified subfederation within the federation infrastructure. The system accesses the joining node's group table, where the group table includes membership information identifying subfederations within the federation infrastructure. Each node in the federation maintains neighborhood information for each subfederation of which the node is aware. The system determines that no entry for the identified subfederation exists in the joining node's group table and, based on the determination, routes a group join message to a rendezvous point within the federation infrastructure. The rendezvous point checks its group table for an entry corresponding to the identified subfederation. The system also receives an indication from the rendezvous point indicating that the rendezvous point's group table does not include a corresponding entry for the identified subfederation and that the joining node is the first member of the identified subfederation.

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： Architecture that applies to a collection of nodes (e.g., a federation) and manages membership of the nodes to the collection via an external datastore. The storage of node state and collection state is stored in the external and highly available datastore. New nodes can now join the collection through the external store. The machines (nodes) in the collection create a lease with the external store that allows the external store to maintain precise knowledge of the set of machines alive in the collection. The external store thus allows the new machines to join the collection while ensuring that there exists only one ring in the collection. In other words, the disclosed architecture protocol ensures that any given point of time there is just one ring for the collection. Moreover, this can be in addition to a current join protocol, which ensures that consistent routing is available.

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.
