Abstract: A routing control methodincludes: the network device obtains a route suppression request; determines the second routing entry; and sets a state of the second routing entry to a non-delivery state that is used to indicate that the second routing entry does not need to be delivered to a forwarding table. Wherein the network device has a first routing entry and a second routing entry, an address prefix of the first routing entry is a first address prefix, an address prefix of the second routing entry is a second address prefix, a network segment to which the second address prefix belongs is a subset of a network segment to which the first address prefix belongs, and a mask in the second address prefix is greater than a mask in the first address prefix.

Abstract: Embodiments of the present invention disclose a path determining method, apparatus, and system. In a hybrid network including one controller for implementing a control function, the controller may separately obtain network topology information of a first network and a second network of different network types by using a same control channel protocol. When the controller obtains a path determining requirement for the data transmission path, because the controller has the network topology information of the first network and the second network, during computation of the data transmission path, the controller can determine a path computation result including transmission path parts of the first network and the second network, without performing additional information exchange with another device, and send the path computation result to the first network device. In this way, planning efficiency of the data transmission path is improved.

Abstract: This application discloses a communications method and apparatus. The method includes: sending, by a session management network element, first indication information when the session management network element determines, based on first information, to establish a first low-latency service flow for a session; and the first indication information is used to indicate to set the session to an always-on session. According to solutions of this application, when determining, based on the local configuration information, the subscription data, and the QoS parameter, to establish the low-latency service flow, the session management network element flexibly indicates a terminal apparatus to set the session to the always-on session. This avoids a resource waste caused by setting the session to the always-on session all the time, and avoids a transmission latency caused when the session is not set to the always-on session in time, so that resource utilization and transmission efficiency are improved.

Abstract: A method includes receiving, by a forwarder, rule modification information sent by a controller. The rule modification information includes rule description match information and action instruction modification information. The rule description match information is used to determine a to-be-modified processing rule. Rule description information of the to-be-modified processing rule accords with the rule description match information, and the action instruction modification information is used to instruct to modify an action instruction specified in an instruction set of the to-be-modified processing rule. The method also includes modifying, by the forwarder, when the forwarder determines that rule description information of a first processing rule meets the rule description match information, an action instruction specified in an instruction set of the first processing rule according to the action instruction modification information.
