US Patent 10200258 Transaction integrity for network services configuration

In some examples, a controller provisions services for transporting packet flows within a network. A controller service provisioning module receives a service request that comprises a definition for a service to be provided by the network for a subscriber or a customer of the network. The service provisioning module determines a plurality of network resources of at least one network device to be configured to implement the service in the network and apply the service to the packet-based network traffic of the subscriber. A locking unit of the service provisioning module acquires a lock from a network-wide coordination repository that stores a software representation for each of the network resources, the lock providing exclusive configuration access to the service provisioning module for the network resources. The service provisioning module, only upon the locking unit acquiring the lock for the network resources, configures the network resources to provision the service.
