Abstract: The present application discloses a service data packet encapsulation method and apparatus. The method includes at least: obtaining, by a source communications device, a mobility support parameter of a current service, where the mobility support parameter is used to indicate whether a corresponding service requires mobility support, and the source communications device includes at least an ID identifier layer and a locator layer; determining, by the source communications device based on the mobility support parameter of the current service, whether the current service requires mobility support; and obtaining, by the source communications device, a source locator of the source communications device and a destination locator of a destination communications device when determining that the current service does not require mobility support, and performing, by using the source locator and the destination locator, locator layer encapsulation on a data packet that needs to be sent by the current service.

Abstract: The present application provides a packet sending method and a network device. The packet sending method includes: receiving, by a network device, a first data packet; and if a MAC entry matching a destination MAC address of the first data packet is not found in a media access control MAC address table of the network device, sending, by the network device, the first data packet according to a forwarding behavior in a MAC default entry of the MAC address table. When the MAC entry matching the destination MAC address of the first data packet is not found, the network device does not need to flood the first data packet on all interfaces, but directly sends the first data packet according to the MAC default entry in the own MAC address table, thereby reducing a need for MAC address capacity in the network device, and not increasing unnecessary network traffic.
