Abstract: A reverse address resolution method and an electronic device are provided. In this method, a sender electronic device broadcasts a first request packet. An Ethernet payload of the first request packet includes a media access control (MAC) address of a target electronic device. After receiving the first request packet, the target electronic device determines that an IP address of the target electronic device is requested, and returns a first reply packet. An Ethernet payload of the first reply packet includes the internet protocol (IP) address of the target electronic device. According to the technical solutions provided in this application, the sender electronic device obtains the IP address of the target electronic device based on the MAC address of the target electronic device through interaction at a data link layer. Therefore, in a mobile distributed system, the IP address of the target electronic device is quickly obtained without relying on a server.

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: Embodiments of the present invention provide a method and an apparatus for forwarding multicast traffic. The method includes: receiving a third multicast join message; in response to the third multicast join message, sending a first multicast join message to a first upstream router, and establishing an active path; in response to the third multicast join message, sending a second multicast join message to a second upstream router, and establishing a standby path; and sending multicast traffic to the multicast receiver through the active path, where the standby path does not forward the multicast traffic. In the foregoing embodiments, the standby path that does not forward the multicast traffic is established beforehand, so that when a fault occurs in the active path, the standby path established beforehand can be used to forward the multicast traffic.
