Embodiment Construction

[0041] The embodiment of the present invention provides a data flow shaping (Traffic Shaping) method, which is used to reduce the queue-jumping operation of data packets and realize data flow shaping in the network. The embodiment of the present invention also provides a related data scheduling method and device, which will be described respectively below.

[0042] If the network is congested while transmitting multiple data streams, the data packets in each data stream may be discarded. In order to meet the user's requirements for different application quality of service, it is necessary to allocate and schedule resources according to the user's requirements, and provide different service quality for different data streams, for example: provide higher processing priority for real-time and important data streams level; it provides lower processing priority for ordinary data streams that are not real-time, and even discards data packets in ordinary data streams when the network...

Abstract

The embodiment of the invention discloses a data stream shaping method. The method is used for reducing queue jumping operation of data packets and realizing data stream shaping in a network. A data stream shaping device calculates first virtual time of receiving a first data packet according to a virtual clock method, and selects a target data queue for the first data packet from N data queues according to the first virtual time and a time period corresponding to each data queue in the N data queues, wherein the N is an integer greater than or equal to 2. After determining the target data queue, the data stream shaping device adds the first data packet to the tail of t he target data queue. The embodiment of the invention also provides a related data scheduling method and device and a computing device.

Description

technical field [0001] The invention relates to the field of data flow control, in particular to a data flow shaping method, a data scheduling method and a device. Background technique [0002] When the network transmits multiple data streams, congestion may occur, resulting in packet delay, loss or even error, and the network transmission performance is not good. In order to ensure efficient operation of the network, a virtual clock (Virtual clock) technology is proposed. [0003] Virtual clock is a scheduling mechanism based on flow control. It calculates the virtual time stamp of data packets according to the average transmission rate of each data flow, and sorts the data packets according to the time stamps to achieve data flow shaping and reduce bursts. Purpose. [0004] However, if the virtual time of the arriving data packets is relatively small, in order to sort the data packets according to the virtual time stamps, it is necessary to compare the time stamps of the...
