Device and method for allocating aggregated link bandwidth in packet-switched network

The invention discloses a method for allocating an aggregated link bandwidth in a packet-switched network, comprising the following steps: matching the idle bandwidth and the service flow request bandwidth of each member link in the aggregated links respectively to obtain all the fault-free member links meeting the demand of the request bandwidth, and selecting the fault-free member link with the minimum bandwidth utilization as a service flow allocation bandwidth. The invention further discloses a device for allocating the aggregated link bandwidth in the packet-switched network. Due to the adoption of the device and method for allocating the aggregated link bandwidth in the packet-switched network, the load balance between the member links can be guaranteed, the congestion of the links can be reduced, and the efficiency of forwarding services can be improved.
