Abstract
A network switch and system for detecting the capacity of available paths in a network and for modifying traffic distribution at each stage of the network, such that traffic is proportionally balanced across the unequal capacity paths. A centralized controller manipulates path weights on each switch such that a load is distributed proportionately to the capacity available to ensure that all available capacity is evenly utilized. A central view of the network is used to determine capacity information, calculate a minimal change set to optimize the traffic flows, and modify the existing multipath group objects. A centralized application can use the capacity information of each switch to build a capacity model of the network. Once the full model has been built up by the application, programming of the specific decisions is done via the controller through an API in communication with each network device's local agent.
