Claim 12:
13. A communications apparatus, wherein the apparatus comprises:
a processor, configured to recover, when detecting that a first packet is lost, the first packet according to a local recovery mechanism, wherein the first packet is a packet obtained based on a packet sent by a first terminal to a second terminal, and the apparatus is a node on a network path between the first terminal and the second terminal;
the processor is further configured to add first identification information that is related to the local recovery mechanism to the first packet; and
a transmitter configured to send the first packet;
wherein the first identification information is used to indicate that the first packet is a packet recovered according to the local recovery mechanism, the first identification information is used to indicate a quantity of times for which the first packet is recovered, or the first identification information is used to indicate that a current network status is network congestion;
wherein the apparatus further comprises a receiver configured to receive the first packet;
wherein the transmitter is further configured to send the first packet to a second node, wherein the second node is another node, other than the apparatus, on the network path between the first terminal and the second terminal communicating with the first terminal; and
wherein the processor is further configured to detect, according to a packet acknowledgment mechanism, whether the first packet is lost in a process of transmitting the first packet to the second node.
