Abstract:
1. A method for equalizing flows, comprising: receiving, by a relay node, a link setup request of a service flow sent from a source node; acquiring, by the relay node, link load information of each bearer network between the source node and a destination node according to the link setup request of the service flow, and selecting a bearer network with a less link load to set up a forwarding link for the service flow; storing, by the relay node, the forwarding link information of the service flow in a local forwarding table; and forwarding, by the relay node, the service flow according to the forwarding link in the local forwarding table; wherein the source node is an Asynchronous Transfer Mode/Internet Protocol (ATM/IP) dual-stack base station controller, the relay node is an ATM/IP dual-stack Hub, when the destination node is an ATM base station, and the bearer network of the forwarding link between the ATM/IP dual-stack Hub and the ATM/IP dual-stack base station controller is an ATM network, the forwarding the service flow by the relay node according to the forwarding link information in the local forwarding table comprises: receiving an ATM cell sent from the ATM/IP dual-stack base station controller; searching the local forwarding table according to header information of the ATM cell, and acquiring forwarding link information of the ATM cell; and forwarding the ATM cell to the ATM base station according to the forwarding link information.
