摘要： A method and a network device in a cloud computing system, including a first blockchain component that is one of a plurality of blockchain components forming a blockchain system, of dynamic discovery of another blockchain component of the blockchain system are described. A multicast address including a multicast group identifier is generated. The multicast group identifier is generated at least in part based on a genesis block identifier that uniquely identifies a blockchain serviced by the blockchain system. The network device joins a multicast group identified by the multicast group identifier; and transmits a message destined to the multicast address, where the message includes a request for a unicast address of another component of the blockchain system.

摘要： A method in a network node is provided for mitigating disruption during maintenance of an edge gateway node of a communication network. The edge gateway node connects devices to services(s) of the communication network. First device(s) are capable of connecting to a cloud environment in the absence of the edge gateway node, and second device(s) are incapable of connecting to the cloud environment in the absence of the edge gateway node. The method comprises: establishing respective virtual devices for the second device(s), the virtual devices comprising predictive models trained to replicate data output by the respective second device(s); and, during a time interval in which the maintenance of the edge gateway node is performed: configuring the virtual device(s) to connect to a virtual edge gateway node established in the cloud environment; and configuring at least one of the first device(s) to connect to the virtual edge gateway node.

摘要： It is provided a method for managing a smart contract in real-time. The method is performed in a contract manager and comprises the steps of: obtaining a base version of the smart contract between the supplier and a first purchaser; recommending amendments to the base version of the smart contract, based on historic contract compliance data of the supplier, wherein the historic contract compliance data is based on smart contracts with the supplier and a plurality of purchasers; receiving a signal indicating an agreed smart contract between the first purchaser and the supplier; receiving a real-time monitoring signal relating to a compliance of the supplier in relation to at least one condition of a smart contract between the supplier and a second purchaser; and recommending amendments to the agreed smart contract, based on the monitoring signal.

摘要： A method and a network node for managing access, by a device, to a blockchain. The network node receives, a first request for creation of a first account. The first request includes information relating to a user of the device and a first hash value. The network node creates, based on the information and the first hash value, the first account on the blockchain, whereby a first address is obtained. The network node receives, a second request for recovering account information of the first account. The second request includes the first address of the first account, a source value from which the first hash value is derived and a second address of a second account. The network node generates a second hash value based on the source value. The network node initiates transfer of the account information of the first account to the second account.

摘要： A method for managing provenance information associated to one or more interconnected provenance entities in a provenance system for data processing pipelines in a distributed cloud environment over a network interface, wherein each of the data processing pipelines is configured to read in data, transform the data, and output transformed data is disclosed. The method comprises steps being performed by a configuration component of obtaining at least one declarative intent representing a configuration indicative of requirements and levels of priority for storage of provenance information for each of the data processing pipelines, deriving the requirements and levels of priority for storage of provenance information for each of the data processing pipelines based on the obtained at least one declarative intent, wherein one of the levels of priority—first level of priority—is higher than the other levels of priority—second levels of priority, estimating storage capacity for storage of provenance information in the provenance system based on the derived requirements and levels of priority, storing the provenance information according to the derived requirements and levels of priority for storage of provenance information and for each of the data processing pipelines, and when actual storage consumption for storage of provenance information in the provenance system meets a threshold of storage capacity set based on the estimated storage capacity: reducing a data amount for storage of provenance information of the second levels of priority in the provenance system. Corresponding computer program product, arrangement, configuration component, and system are also disclosed.

摘要： Methods and systems are disclosed for managing cloud services using smart contracts to facilitate various functions, such as tenant login, tenant enrollment, service registration, tenant usage charging, tenant usage tracking, tenant quota management, and tenant rights revocation. The proposed techniques allow tenant and service accounts to be represented as smart contracts, and for services to delegate authorization for bundles of service attributes to tenants and other services, for which the tenants and services are then charged. The business logic is implemented on a permissioned, distributed ledger (e.g., a private blockchain) and therefore is easily customized for specific classes of tenants and services.

摘要： Methods and systems for authorizing the access of a service are described. A server is operative to receive a request to subscribe to a service. The server is to receive from the requestor a selected service offer from the set of service offers, where the selected service offer is cryptographically signed with the private key of the requestor and the private key of the service. The server is further to record a delegation contract into a blockchain database, where the delegation contract includes an identification of the service, an identification of the requestor, and the service offer that is cryptographically signed with the private keys of the requestor and the service. The server is to transmit, to the requestor, a confirmation that the service can be accessed based on the selected service offer; and transmit to the service the delegation contract causing the service to provide access to the requestor.
