This application provides a method and an apparatus for configuring a service, which help to implement automatic configuration of a service and improve efficiency. The method provided in this application includes: obtaining, by an NaaS device, a contract of a service, where the contract includes identifier information and a condition, the identifier information is used to identify a first device group, the first device group includes a device that provides the service, and the condition is a communication requirement corresponding to the service; obtaining, by the NaaS device, information about a network device group according to the identifier information and the condition; obtaining, by the NaaS device, a first forwarding rule according to the condition, where the first forwarding rule corresponds to the network device group; and sending, by the NaaS device, the first forwarding rule and the information about the network device group to a controller.

Method and apparatus for NaaS device configuring service

A network device obtains, from a transaction queue, a plurality of transactions that do not conflict with each other, and performs reverse shallow copying in parallel for the transactions that do not conflict, to generate a plurality of temporary trees corresponding to the plurality of transactions. Because the plurality of transactions does not conflict with each other, processing the transactions in parallel can ensure accurate and proper transaction processing. In addition, generating the temporary trees in a reverse shallow copying manner can effectively reduce consumption of time and memory. Further, processing of the plurality of transactions is implemented by merging the plurality of temporary trees.

Method for NaaS device configuring service

A network as a service (NaaS) service cross-domain orchestration method to implement an end-to-end NaaS service in a multi-domain network that includes multiple network domains where the method includes obtaining information about a first user-to-network interface (UNI) and information about a second UNI in a multi-domain network according to a received NaaS service request, where the NaaS service request is used to request to establish an NaaS service between a first terminal and a second terminal; querying domain resource information to obtain a cross-domain path between the first UNI and the second UNI; determining network domains that the cross-domain path passes through, and obtaining a first connection requirement and a second connection requirement of each network domain of the network domains that the cross-domain path passes through; and sending the first connection requirement and the second connection requirement to a control device in each network domain.

This application discloses a policy conflict resolution method which includes receiving a first control policy and decomposing the first control policy into m first rules, and receiving a second control policy and decomposing the second control policy into n second rules. The method also includes performing negation on each first rule to obtain a first negation rule, performing negation on each second rule to obtain a second negation rule, and generating a corresponding first execution rule by using each first negation rule and each second negation rule according to a rule synthesis principle. Additionally, the method includes deleting an invalid rule, using a remaining one of the first execution rules as a valid first execution rule, performing negation on each valid first execution rule, and converting, according to a protocol supported by a first forwarding device, each valid first execution rule on which negation has been performed into a corresponding forwarding entry of the first forwarding device.

Policy conflict resolution method and apparatus

The present invention provides a method for receiving information, a method for sending information, and apparatuses for the same. The method for receiving information includes: when a control plane apparatus is capable of managing a forwarding plane apparatus, receiving, by the forwarding plane apparatus, information used for packet forwarding path calculation sent by the control plane apparatus, where the forwarding plane apparatus and the control plane apparatus are located in a network with a network architecture featuring forwarding and control element separation. According to the technical solutions provided in embodiments of the present invention, the forwarding plane apparatus does not need to actively obtain the information used for packet forwarding path calculation before calculating a packet forwarding path based on the information used for packet forwarding path calculation.
