Abstract: Various embodiments provide an example method in which a first measurement packet can be generated. The first measurement packet includes link resource indication information, and the link resource indication information in the first measurement packet is configured to indicate each node on a forwarding path of the first measurement packet to perform local link resource measurement. In those embodiment, the first measurement packet can be sent to a next device on the forwarding path, where the first measurement packet includes local link resource information measured by the first device. Still in those embodiments, until the first measurement packet is forwarded to a third device by each node on the forwarding path of the first measurement packet, the third device receives the first measurement packets sent on different forwarding paths, and determines a path meeting the link resource indication information.

Abstract: Embodiments of the present invention provide a method for selecting a negotiation counterpart. Specifically, the first device sends a discovery message in the network, and the discovery message includes a technical objective. The first device receives a first response message with which a second device replies, and receives a second response message with which a third device replies. The first response message carries information about a characteristic that is of the second device and that supports implementation of the technical objective, and the second response message carries information about a characteristic that is of the third device and that supports implementation of the technical objective. The first device can select a device with a higher technical objective support degree from the second device and the third device as the negotiation counterpart according to the first response message and the second response message.

Abstract: The application provides a method and a router for sending and processing data. In the method, a first router receives a first Internet Protocol IP data packet sent by a network server, where the first IP data packet carries a first data adding instruction; and the first router searches, according to the first data adding instruction, a first local cache for to-be-added data that is indicated by the first data adding instruction, adds, to the first IP data packet, the to-be-added data that is indicated by the first data adding instruction, to form a second IP data packet, and sends the second IP data packet. Because a router can add data to an IP data packet according to a data adding instruction, flexibility of data combinations is improved, and because the IP data packet can support multiple times of data adding, the flexibility of data combinations is further improved.
