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 includes a first node obtaining a first target bandwidth of first traffic on a first path, where the first path is a path used to transmit the first traffic from the first node to a second node. The first target bandwidth is not greater than a minimum value in remaining available bandwidths of single-hop links on the first path, and a single-hop link is a link between two directly connected nodes. The first node sends the first traffic on the first path based on the first target bandwidth. Accordingly, before traffic is transmitted in the network device, available bandwidth resources are predetermined for the traffic, and the traffic corresponding to the available bandwidth resources is transmitted on the determined available bandwidth resources.

Abstract: A data processing method and a related device are provided. The method includes receiving, by the ith processing circuit in a first circuit set, a first packet header and data D(1, i−1), obtaining data D′(1, i) based on a first field in the first packet header, and sending the first packet header and data D(1, i) to the (i+1)th processing circuit in the first circuit set, where the data D(1, i) is obtained based on the data D(1, i−1) and the data D′(1, i). The method also includes sending, by the ith processing circuit in the first circuit set, the data D(1, i) to the (i+1)th processing circuit in a second circuit set and sending, by the ith processing circuit in the second circuit set, a second packet header to the (i+1)th processing circuit in the second circuit set.
