Abstract: Embodiments of this application provide a data frame sending method and a network device. The method includes: A first node obtains routing label stack information of a first path, where the first path is used to transmit a service, and the routing label stack information indicates each node on the first path to establish a channel of the service on the node of the first path. The first node inserts the routing label stack information and service attribute information into a payload area of a first data frame, where the service attribute information indicates each node on the first path to configure a resource for the service. The first node sends the first data frame. In the foregoing method, routing label stack information and service attribute information are carried in a payload area of a data frame, so that service routing information can be quickly transmitted to each node on a service path, and is used by each node to quickly establish a channel for transmitting a service and configures a resource for the service, thereby shortening routing time.

Abstract: Embodiments of the present invention disclose a failure recovery method for a virtual network, including: determining, by a network device (for example, a transport controller), that a physical link in a physical network fails, where the failed physical link corresponds to at least one virtual link in the virtual network; and mapping the at least one virtual link corresponding to the failed physical link to a non-failed physical resource in the physical network, where the non-failed physical resource satisfies a transmission bandwidth of each of the at least one virtual link. According to the foregoing technical solution, failure recovery can be performed on the virtual network. When a physical resource corresponding to the virtual network fails, the failure recovery can be quickly performed on the virtual network, and a topology of the virtual network after the failure recovery is the same as that before the failure occurs, thereby improving user experience.
