DISTRIBUTED SERVICE ACTIVATION METHOD VIA BLOCKCHAIN

A multi-domain telecommunication network may use a blockchain with an activation block to activate a reserved connection path for a service. The network may use a correction block in the blockchain to efficiently and timely perform a crank-back procedure. A management node of a domain of the network may act as an activation miner send activation messages to management nodes of other domains of the network, the management nodes may perform activation for their respective portions of the connection path reserved by the activation block. The management node acting as the activation miner may verify activation of reserved resources and, in case of failure, generate a correction Block to lock the failed resources and to release the resources affected by the crank-back process. Subsequent blockchain decisions and calculations may reflect the actual status of network resources.
