Embodiments of the present invention provide a method for bandwidth adjustment in a network virtualization system. The network virtualization system includes a central module and m remote modules, where the m remote modules are connected to a physical interface of the central module by n PWs. The method includes: acquiring, from the m remote modules, a real-time bandwidth of each PW of the n PWs; when a sum of the acquired real-time bandwidths of the n PWs is greater than a bandwidth of the physical interface, adjusting configured bandwidths of P PWs; and separately sending values of adjusted configured bandwidths of the P PWs to the remote modules separately connected to the P PWs. The embodiments of the present invention further provide an apparatus for bandwidth adjustment. By using technical solutions provided by the embodiments of the present invention, when it is determined that the sum of the real-time bandwidths of the n PWs is greater than the bandwidth of the physical interface, the configured bandwidths of the PWs of the remote modules are adjusted, so that problems of network congestion and packet losses that occur on the central module are avoided to the greatest extent. |
