Abstract: A method and an apparatus for sending a TCP data packet and a system. The method includes: obtaining a first round-trip time of sending a TCP data packet in a network, and determining a second round-trip time; if the first round-trip time is longer than the second round-trip time, using a congestion window determined according to a first algorithm as a first congestion window; otherwise, using a congestion window determined according to a second algorithm as the first congestion window; and sending the TCP data packet by using the first congestion window. In the technical solution disclosed in the present invention, a current congestion window that exists when a first round-trip time is obtained grows to a first congestion window at one go, so that a requirement of a service for a throughput can be better met, and a network bandwidth can be utilized more effectively.

Abstract: The present disclosure relates to methods and devices for obtaining path information of a data packet. One example method includes receiving, by a network device, a data packet transmitted in a network, and obtaining, by the network device, path information of the data packet from a source end to a destination end, where the path information is a total hop count of routers passed through by the data packet from the source end to the destination end or a latency of the data packet from the source end to the destination end.
