A dynamic path adjustment method and apparatus for link congestion. In the method, when a label edge router cannot allocate an LSP for a bandwidth requirement of a pre-application link of a data packet to be sent currently, the label edge router determines each LSP to a destination address according to the bandwidth requirement and the destination address; determine whether the sum of reserved bandwidths of all LSPs meets the bandwidth requirement; if yes, use the reserved bandwidth of each LSP to send the data packet to be sent; otherwise, add the bandwidth requirement of the pre-application link of the data packet to be sent to a waiting queue. Whether the current bandwidth requirement can be met is determined according to the sum of reserved bandwidths of all determined LSPs, that is, the reserved bandwidth of each LSP is used as the bandwidth for transmitting the data packet, so that the bandwidth resource is efficiently used, the transmission efficiency of the data packet is improved, and the real-time requirement of data packet transmission is met. |
