Abstract: A packet processing method includes receiving, by a forwarding apparatus, a first packet, where the first packet belongs to a first packet flow, determining, by the forwarding apparatus, at least two types of information in the following four types of information a duration of staying in a first memory by the first packet flow, usage of the first memory, whether the first packet flow is a victim of a congestion control mechanism, and a drop priority of the first packet, and determining, by the forwarding apparatus based on the at least two types of information, whether explicit congestion notification marking needs to be performed on the first packet.

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 communication method includes measuring a received signal strength indicator (RSSI) and a reference signal received power (RSRP) of a serving cell in which a user equipment is located; calculating a load rate of the serving cell based on the RSSI, the RSRP, and at least one of a quantity of antenna transmit ports of a base station communicating with the user equipment, a probability of synchronization between the serving cell of the user equipment and each of neighboring cells, a probability of asynchronization between the serving cell and the neighboring cells, a ratio of power of a data signal from the base station to power of a pilot signal from the base station, or interference caused by the neighboring cells to the serving cell; and determining, based on the load rate of the serving cell and a cell congestion threshold, whether the serving cell is congested.
