A system for processing a streaming media service and a method and a network device thereof are provided. The system includes a network device and an encoder. The network device has an embedded streaming function module. The encoder includes two egress ports, where the two egress ports of the encoder are connected to an active input port and a standby input port of the network device respectively. The encoder is configured to: receive a streaming media service signal, encode the streaming media service signal to generate a streaming media service coded signal, and send the streaming media service coded signal to the network device. The network device is configured to receive, by using the embedded streaming function module through the active input port or the standby input port, a streaming media service coded signal sent by the encoder, and provide the streaming media service coded signal for a terminal.

System for processing streaming media service and method and network device thereof

This application discloses a method for visualized network operation and maintenance, including receiving a request for visualized network operation and maintenance, generating a workflow for visualized network operation and maintenance according to the request for visualized network operation and maintenance, and creating a network modeling input, and performing, according to the workflow for visualized network operation and maintenance, the network modeling input, and original information of network modeling, analog simulation on a network determined by the network modeling input.

Method and apparatus for visualized network operation and maintenance

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.

Method, apparatus and system for sending and receiving a media stream

The present invention discloses a method and a device for fast pushing a unicast stream in a Fast Channel Change (FCC), and relates to the field of Internet Protocol Television (IPTV). A server obtains a multicast join delay of a terminal, determines a minimum value of a data amount between a starting position of a fast unicast stream and a latest packet position according to the multicast join delay of the terminal, a decoding rate, a unicast push rate, and a lowest buffer data amount required for decoding, judges whether a latest I frame completely arrives according to a packet buffer state; and fast pushes the unicast stream starting from the latest I frame if the latest I frame completely arrives, and an arrived data amount starting from the latest I frame is greater than or equal to the minimum value.
