Abstract:
1. A method for joint optimization in a network, wherein the network comprises a plurality of sub-networks, the method comprising: obtaining link information, server and bandwidth information, and user requirement information of a sub-network, wherein the server and bandwidth information comprises virtual server bandwidth of every external port of the sub-network, and the virtual server bandwidth is bandwidth of a server off the sub-network, wherein each external port provides a connection between the sub-network and another sub-network providing the virtual server bandwidth through the respective external port, and wherein the bandwidth of the server off the sub-network is required by the sub-network through the external port; obtaining an optimal routing parameter and a server selection parameter within the sub-network according to the link information, the server and bandwidth information, and the user requirement information; obtaining optimized ingress bandwidth of every external port of the sub-network according to the optimal routing parameter and the server selection parameter; and comparing the optimized ingress bandwidth and the virtual server bandwidth of every external port, and if results of the comparison between the optimized ingress bandwidth and the virtual server bandwidth of all external ports are smaller than a set error value, applying the optimal routing parameter and the server selection parameter for routing and server selection within the sub-network.
