US Patent 10419446 End-to-end policy management for a chain of administrative domains

Managing policies for a chain of administrative domains, from end-to-end, includes receiving, at a network device associated with an administrative domain that is part of a chain of administrative domains provisioning an Internet-based application or an Internet-based service to a network, a root block for a blockchain. The root block is generated by a network device in the network and includes a request for a specific network parameter over a specific time period. The network device associated with the administrative domain appends a first block to the blockchain including the root block to accept the request and configures the administrative domain in accordance with the specific network parameter when an end-to-end path in the chain of administrative domains accepts the request. The network device associated with the administrative domain also generates blockchain transactions that append network status updates to the blockchain during the specific time period.
