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.
Claims30
A method, comprising:
- obtaining, by a first node, routing label stack information of a first path, wherein the first path is used to transmit a service, and the routing label stack information indicates to each node on the first path to establish a channel of the service on the respective node of the first path;
- inserting, by the first node, the routing label stack information and service attribute information into a payload area of a first data frame, wherein the service attribute information indicates to each node on the first path to configure a resource for the service,
- wherein the payload area comprises a first field associated with the routing label stack information and the routing label stack information is inserted into the first field of the payload area, and wherein the payload area comprises a second field and the service attribution information is inserted into the second field;
- and
- sending, by the first node, the first data frame to at least a downstream node further in the first path, and configuring, in parallel with or upon completion of the sending of the first data frame to the downstream node by the first node, of at least the resource for the service.

A method, comprising:
- receiving, by a second node, a first data frame, wherein a payload area of the first data frame carries routing label stack information and service attribute information of a first path, the routing label stack information indicates to each node on the first path to establish a channel of a service on the respective node of the first path, the service attribute information indicates to each node on the first path to configure a resource for the service, and the first path is used to transmit the service,
- wherein the payload area comprises a first field associated with the routing label stack information and the routing label stack information is obtained from the first field of the payload area, and wherein the payload area comprises a second field and the service attribution information is obtained from the second field;
- obtaining, by the second node, the routing label stack information and the service attribute information from the first data frame;
- and
- sending, by the second node, at least a portion of the first data frame to a downstream node further in the first path, and establishing, by the second node in parallel with or upon completion of the sending of at least the portion of the first data frame to the downstream node, a channel of the service on the second node based on the routing label stack information, and configuring a resource for the service based on the service attribute information.

A network device, comprising:
- a processor, configured to:
- obtain routing label stack information of a first path, wherein the first path is used to transmit a service, and the routing label stack information indicates to each node on the first path to establish a channel of the service on the respective node of the first path;
- insert the routing label stack information and service attribute information into a payload area of a first data frame, wherein the service attribute information indicates to each node on the first path to configure a resource for the service,
- wherein the payload area comprises a first field associated with the routing label stack information and the routing label stack information is inserted into the first field of the payload area, and wherein the payload area comprises a second field and the service attribution information is inserted into the second field;
- and
- configure at least the resource for the service;
- and
- a transmitter, configured to send the first data frame to at least a downstream node further in the first path, wherein the processor is configured to configure at least the resource for the service in parallel with or upon completion of the transmitter sending the first data frame to the downstream node.
