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.
