Abstract: A packet processing method includes: a first device receives a packet from a second device; the first device determines a first queue buffer used to store the packet, and determines a first upper limit value of the first queue buffer based on an available value of a first port buffer and an available value of a global buffer, where the global buffer includes at least one port buffer, the first port buffer is one of the at least one port buffer, the first port buffer includes at least one queue buffer, and the first queue buffer is one of the at least one queue buffer. The first device processes the packet based on the first upper limit value of the first queue buffer, an occupation value of the first queue buffer, and a size of the packet.

Abstract: A method, an apparatus, and a system for adjusting a multimedia encoding rate are disclosed. The method includes: obtaining an expected multimedia encoding rate by using the available network bandwidth corresponding to the transmission path of a multimedia service, the expected QoE of the multimedia service, and the current multimedia encoding rate as input parameters and according to a preset multimedia resource policy decision, where the expected multimedia encoding rate is used as a reference for adjusting the current multimedia encoding rate. With the present disclosure, under the current network performance, an optimal point for balancing the effects of the media encoding rate and the network performance on the QoE is found by adjusting the multimedia encoding rate, thus achieving optimal QoE. In this way, the adjustment process is simple and fast and the success rate is high, thus improving the QoE.
