Abstract: A traffic shifting system is described to shift traffic away from one or more network devices or interfaces. The system ensures that traffic can be safely shifted off of a network device before the shifting occurs. The method is described as broken into several phases, such as a discovery phase, a pre-check phase, a shifting phase, and a post-shift phase. Before shifting occurs, the discovery phase is used to obtain network topology and configuration information. In the pre-check phase, that information is interrogated so that a shifting can be performed without negatively impacting the network. If the pre-check phase is passed, then the network shifting can occur through adjustment of configuration parameters, such as a cost parameter associated with an interface on any devices for which traffic is being shifted. Finally, in the post-shift phase, checks are performed to ensure traffic is shifting away from the network device.

Abstract: A traffic shifting system is described to shift traffic away from one or more network devices or interfaces on those devices. The system ensures that traffic can be safely shifted off of a network device before the shifting occurs. The method is described as broken into several phases for simplicity, such as a discovery phase, a pre-check phase, a shifting phase, and a post-shift phase. Before shifting occurs, the discovery phase is used to obtain network topology and configuration information. In the pre-check phase, that information is interrogated so that a shifting can be performed without negatively impacting the network. If the pre-check phase is passed, then the network shifting can occur through adjustment of configuration parameters, such as a cost parameter. Finally, in the post-shift phase, checks are performed to ensure traffic is shifting away from the network device.

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.
