Abstract: Embodiments of the present invention provide a method, an apparatus and a system for sending and receiving a media stream. In the embodiments of the present invention, during a transmission process of media content, if the packet loss occurs, and if retransmission still does not succeed after the retransmission has been attempted for finite times, the retransmission of the lost data packet is abandoned through notification of the retransmission suppression information, and transmission of a subsequent part of media stream is continued, which ensures uninterrupted transmission of the media stream, and avoids the occurrence of a screen mess of a picture, a picture jitter or pause, and even a program interrupt, thereby improving picture quality.

Abstract: A hybrid access gateway receives packets that are sent by a network side device and are destined for a home gateway. When detecting that congestion occurs on a first transmission link and that no congestion occurs on a second transmission link, the hybrid access gateway obtains a first committed information rate (CIR) of the first transmission link and a second CIR of the second transmission link, classifies the packets into a first-type packet and a second-type packet, and transmits the first-type packet using the first transmission link and the second-type packet using the second transmission link. By properly allocating packets transmitted on the second transmission link, the hybrid access gateway can control one-way delays of the first transmission link and the second transmission link, thereby avoiding a packet loss caused by a sequencing buffer overflow.

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.
