Abstract: A link detection technology. In a link detection method, when a target event occurs on paths, in a plurality of paths, whose quantity exceeds a preset quantity, whether the paths on which the target event occurs share a bottleneck link is detected, and congestion control is performed. It can be learned that in the technical solution provided in the embodiments of this application, the target event is a trigger, and shared bottleneck detection is performed after the quantity of the paths on which the target event occurs exceeds the preset quantity. This implements purposeful link detection, reduces system overheads, and brings a fast convergence speed.

Abstract: The present invention provides a data transmission method. In the method, according to a pre-obtained network status variable and a pre-obtained transmission success rate, a transmit end obtains a quantity of redundant data packets that need to be transmitted for a data packet. The transmit end also obtains a redundant data packet scheduling method according to the quantity of redundant data packets. Then the transmit end send a redundant data packet according to the redundant data packet scheduling method.

Abstract: A heterogeneous multi-protocol stack system including a plurality of heterogeneous protocol stack instances is described. Resource allocation between the protocol stack instances is unbalanced, and algorithms are independently configured, so that QoS capacities of different protocol stack instances are different. Data packets of applications or connections with different QoS requirements can be dispatched by a dispatcher to corresponding protocol stack instances at a high speed. When system resources are limited, the heterogeneous multi-protocol stack system is capable of simultaneously supporting classification optimization processing performed on data of a high-concurrency application, a high-throughput application, and a low-delay application, so as to meet QoS requirements of different types of applications, thereby improving user experience.

Abstract: A data transmission acceleration method and related apparatuses are disclosed. A sanding node transmits a plurality of data packets to a receiving node at an initial transmission rate. Each data packet carries a random sequence number and a rolling sequence number. The random sequence number identifies a data part of the data packet, and the rolling sequence number indicates a transmission sequence of the data packet. The sending node receives a packet loss feedback from the receiving node. The packet loss feedback is generated after the receiving node detects a packet loss event according to a rolling sequence number of a received data packet. The sending node determines a random sequence number of a lost data packet based on the received packet loss feedback. The sending node retransmits a data packet corresponding to the determined random sequence number. The retransmitted data packet carries a new rolling sequence number.

Abstract: A data transmission method and apparatus, where a transmission end determines a redundancy time according to a delay requirement of a service, where the redundancy time indicates a time used for transmitting redundant data of native data of the service, and the redundancy time is less than or equal to a time indicated by the delay requirement. The transmission end determines a redundancy quantity N. The transmission end determines N redundancy transmission time intervals according to the redundancy time and the redundancy quantity. After the native data of the service is sent, in case of feedback data is not received within an nth redundancy transmission time interval, transmitting the redundant data of the native data for the nth time according to the nth redundancy transmission time interval.
