Abstract: A method for data transmission includes receiving a packet, determining a first member link in a first group of member links based on a first decision manner. If the first member link is unavailable, the method includes determining a second member link in a second group of member links based on a second decision manner, where all member links in the second group of member links are available and the first group of member links includes the second group of member links and an unavailable member link. The method includes sending the packet through the second member link.

Abstract: In a network congestion handling method, a first network device determines a target port, where the target port is an egress port that is in a pre-congestion state or a congestion state. The first network device sends a first notification to at least one second network device. The at least one second network device is capable of sending, through at least two forwarding paths, a data flow to a host corresponding to the target port. The first notification includes information of a network device to which the target port belongs and information of the target port. The first notification can enable the at least one second network device to perform an operation of avoiding network congestion. The network congestion handling method can effectively alleviate network congestion and improve network bandwidth utilization.

Abstract: Example packet control methods and apparatus are described. One example method includes detecting, by a network node, a packet in a packet flow causing a congestion from an upstream node. The network node reduces a scheduling priority of the packet in the packet flow and generates a congestion isolation message, where the congestion isolation message includes description information of the packet flow. The congestion isolation message is sent to the upstream node to instruct the upstream node to reduce the scheduling priority of the packet in the packet flow.

Abstract: In a method, a controller sends a first route update packet including a first route to a first forwarding device, so that the first forwarding device sends a third route update packet including a third route to at least one target forwarding device; a second forwarding device receives the third route update packet, determines a target link from the first forwarding device to the second forwarding device, and sends, based on a monitored state of the target link, a second route update packet including a second route and a target field to the controller; and the controller determines the state of the target link based on the target field in the second route update packet.

Abstract: 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.

Abstract: A faulty link detection method includes receiving statistical data that is reported by all nodes every preset quantity of packets that carry a program clock reference value. All the nodes collect statistical data starting from a unified program clock reference value. The quantity of packets lost between an upstream node and a downstream node among all the nodes is acquired according to the statistical data. A faulty link is determined according to the quantity of packets lost between the upstream node and the downstream node.
