  • Publication number: 20200036583
    Abstract: Certain embodiments described herein are generally directed to consistent processing of transport node network configuration data in a physical sharding architecture. For example, in some embodiments a first central control plane (CCP) node of a plurality of CCP nodes determines a sharding table, which is shared by the plurality of CCP nodes. In certain embodiments, the first CCP node determines a connection establishment between a first transport node and the first CCP node. In some embodiments, if the first CCP node determines, based on the sharding table, that it is a physical master of the first transport node, the first CCP node receives network configuration data from the first transport node, stores at least a portion of the network configuration data, and transmits a data update comprising at least a portion of the network configuration data to a shared data store accessible by the plurality of CCP nodes.

    Abstract: An apparatus including processing circuitry and a method are described. When receiving a cross-chain transaction request to transfer a resource from a first account to a second account, the processing circuitry is configured to generate a task corresponding to the first account. The task can indicate conditions for implementing events in transferring the resource. A first blockchain system provides services for the first account, and a second blockchain system different from the first blockchain system provides services for the second account. The processing circuitry transfers the resource to the second account based on the task when a first plurality of first nodes in the first blockchain system reaches a consensus on a generation event of the task and updates a task status of the task to being finished when a plurality of second nodes in the second blockchain system reaches a consensus on a transfer event of the resource.

  • Patent number: 10476744
    Abstract: A method is provided for a coordinator to manage cluster membership. In a stable state, the coordinator provides a member list to all the nodes in a node list. The member list includes nodes that are cluster members. The node list includes nodes that are or wish to be members of the cluster. When the node list differs from the member list, the coordinator advances to a reconfiguration state to change the membership of the cluster. In the reconfiguration state, the coordinator sends a reconfiguration request to all the nodes in the node list. When reconfiguration acknowledgements are received from all the nodes within a timeout period, the coordinator updates the member list to be equal to the node list, persists the updated member list, sends a reconfiguration confirmation including the updated member list to all the nodes in the node list, and returns to the stable state.
