摘要： Embodiments of this application relate to the field of communication technologies, and provide a routing information publishing method. The method includes: An edge transport device connected to a first edge device in a first network domain receives, based on a control plane protocol message, first routing information that is from a controller and that includes an address of a second edge device in a second network domain and a destination address of the second network domain, and sends the first routing information to the first edge device, so that the first edge device generates, based on the first routing information, a forwarding table that is of the first edge device and that is used to indicate a forwarding relationship between the first network domain and the second network domain.

摘要： A mechanism is disclosed for implementing conditional commands carried by network data packets. A data flow including a data packet is received. The data packet includes a conditional command. A condition and a command are obtained from the conditional command. The mechanism determines that the condition is satisfied. Based on the determination that the condition is satisfied, the command is executed to alter handling of the data flow, alter handling of the data packet, or alter a context for the data flow.

摘要： A machine learning technology-based fault management system for network equipment that supports SDN OpenFlow protocol that includes an L2 switch or a router, which is network equipment connected to a client; and an Artificial Intelligence (AI)-based Software Defined Network (SDN) controller requested for management commands for each scenario when the L2 switch or the router, which is network equipment connected to the client, encounters a network fault so that a Simple Network Management System (SNMP) agent installed in the L2 switch and the router determines the type of fault occurred on a network and AI is employed to recover from a current fault through learning results from past data. An effect is achieved that not only service quality is improved through real-time fault management using an AI-based automatic response against a network fault but also a fault is precisely overcome by using the AI-based automatic response.

摘要： A method implemented by a controller configured to implement a border gateway protocol (BGP) and control a Bit Index Explicit Replication Traffic/Tree Engineering (BIER-TE) domain. The method includes generating an update message comprising a BIER-TE path subsequent address family indicator (SAFI), a network layer reachability information (NLRI) including a distinguisher, and an attribute including a type length value (TLV) having a tunnel type and a path bit positions sub-TLV. The method further includes distributing the update message to a bit forwarding router (BFR) in the BIER-TE domain.

摘要： A processor-implemented method includes receiving a network topology describing a network. The method also includes receiving a set of traffic patterns for the network, and a set of network upgrade plans for the network. The method obtains a set of performance parameters from a list of bottleneck structures based on the set of traffic patterns and the network topology, for each upgrade plan. The method then selects a preferred network upgrade plan from the set of network upgrade plans based on the performance parameters.

摘要： This application provides a route information processing method, a communication apparatus, and a communication network, applied to the communication technology field. The route information processing method is used on a target node in a first network. The first network is addressed based on a tree first topology structure, and an address of a child node in the first topology structure includes an address of a parent node. Therefore, a node in the first network may calculate a route based on a destination address. When a topology structure of the first network is updated from the first topology structure to a second topology structure, and a connection relationship of a first node changes, the target node in the first network may add route information destined for the first node, so that the target node can still correctly address the first node and a descendant node of the first node.
