Abstract: A network path measurement method. The method includes: obtaining a first aggregate available bandwidth of a path from the first switching node to a second switching node; obtaining a first available bandwidth of a path from a first target port of a third switching node to the first switching node, where the third switching node is a next-stage switching node connected to the first switching node; obtaining, a second available bandwidth of a path from the second switching node to a fourth switching node, where the fourth switching node is a next-stage switching node connected to the second switching node; and determining a second aggregate available bandwidth of a path from the first target port of the third switching node to the fourth switching node, the second aggregate available bandwidth is a smallest available bandwidth among the first aggregate available bandwidth, the first available bandwidth, and the second available bandwidth.

Abstract: This application discloses a method for controlling traffic in a packet-based network. In the method, after receiving a control packet from a transmit end, an intermediate node between the transmit end and the receive end sends a control packet at the head of a first control queue based on a first duration, wherein the first duration is obtained based on a committed burst size (CBS) and a first committed information rate (CIR), and the intermediate node is configured to send a packet of a first transmit end to a first receive end in the packet-based network. After sending the control packet in the control queue, the intermediate node sends a first data packet set at the head of a data queue based on the sent control packet, wherein the first data packet set comprises C data packets, and C is an integer greater than or equal to 1

Abstract: This application provides a method for transmitting path load information and a network node. The method includes: obtaining, by the network node, M pieces of path load information; aggregating, by the network node into one load metric based on the M pieces of path load information, load of all shortest paths that are from the network node to the destination node and that pass through M adjacent nodes corresponding to the M pieces of path load information, where the load metric indicates total load of all the shortest paths from the network node to the destination node; and sending, by the network node, information about the load metric to another adjacent node other than the M adjacent nodes of all adjacent nodes of the network node.
