摘要： Embodiments of the present invention provide a data flow processing method and apparatus, and a system. A processing process performed on a packet is divided into multiple processing actions. Some processing actions are spread only when traffic of a current data flow meets a preset condition. Therefore, multiple processor cores may process a packet in a pipeline manner, so as to improve processing efficiency. When a bandwidth fluctuation amplitude of a data flow is relatively large and a peek bandwidth of the data flow is relatively large, compared with a static pipeline manner, the method provided in the embodiments of present invention avoids a waste of processing resources to some extent when traffic is relatively low, and can also better support data flow processing when traffic is relatively high.

摘要： Embodiments of the present invention provide a cell processing method and apparatus. The method includes: obtaining, by a first sending end, a first timestamp compensation time; adding, by the first sending end, the first timestamp compensation time to a first timestamp carried in a first cell, where the first timestamp is a sending time of the first cell; and sending, by the first sending end to a receiving end, the first cell that is added with the first timestamp compensation time, so that the receiving end forwards the first cell according to the first timestamp that is added with the first timestamp compensation time. In the embodiments of the present invention, a first timestamp compensation time is added to a first timestamp carried in a first cell, to prevent a second cell, which is sent by a second sending end, from waiting at the receiving end for a cell that is sent by a first sending end at a time the same as a sending time of the second cell, where the cell reaches the receiving end after a longer delay time than a delay time after which the second cell reaches the receiving end, which improves cell forwarding efficiency of the receiving end and prevents the occurrence of cell accumulation in a link.

摘要： Provided are an HQoS scheduling method and device. A received uplink data packet is encapsulated and stored in a queue in uplink direction, and an uplink queue scheduling component is requested to perform scheduling. In this manner, HQoS scheduling in the uplink direction is implemented, and a personalized demand of a user can be met by scheduling uplink data, to carry out more flexible function customization. According to the method and device, the data packet may be further sent to a downlink direction after the HQoS scheduling in the uplink direction is completed, and the HQoS scheduling can be performed on the data in the downlink direction, so that the HQoS scheduling is respectively performed on the data in both the uplink direction and the downlink direction; in this manner, the real bidirectional HQoS scheduling control is implemented, and QoS of the user service can be guaranteed in both directions.

摘要： The embodiments of the present invention relate to a method for implementing flow control in a switch fabric, a switching device, and a switching system. The method includes: sending, by each input port, request information to a destination output port where no packet congestion occurs; according to respective back pressure information, determining, by the destination output port which receives the request information, whether to return grant information to each input port to establish a matching relationship between each input port and the destination output port which returns the grant information; according to the matching relationship, scheduling, by each input port, a cell to a destination output port that is matched with each input port. Through the embodiments of the present invention, quantity of information transmitted between an input port and an output port is reduced, the design of the switch fabric is simplified, and data processing efficiency in the switch fabric is improved. At the same time, a problem of queue head of line blocking is solved by filtering a destination port where congestion occurs, so that performance of the switch fabric is improved.
