Abstract: This application discloses a roaming charging method and apparatus. A blockchain network stores information related to roaming fee settlement, to reduce a possibility that the information related to roaming fee settlement is tampered with. In addition, a digital signature algorithm is used to sign roaming service statistics to generate an abstract, to further prevent the roaming service statistics from being tampered with. In this way, when a home carrier verifies a roaming account balance by using the roaming service statistics and a roaming charging rule, accuracy of a verification result can be ensured, and the home carrier can obtain an accurate roaming fee of a user.

Abstract: The present disclosure relates to the field of communications technologies, and provides a multi-stream transmission method and device in an SDN network. A server obtains network status information of a network by using an SDN controller; determines, according to the network status information and a data sending rate requirement of a client, a quantity of sub-streams and a sub-stream transmission path that are required by a multi-stream connection, and allocates corresponding sub-stream identification information to each sub-stream; and sends the determined sub-stream transmission path and the corresponding sub-stream identification information to the SDN controller. According to the foregoing solution, the server completes multi-stream connection path planning according to the network status information, and the SDN controller only provides the network status information for the server without performing the multi-stream connection path planning, so that calculation load of the SDN controller is reduced.
