Abstract
A method for adjusting capacity in a multi-stage routing network includes monitoring a number of available connections between a router in a first stage of a multi-stage router network and one or more routers in a second stage of the multi-stage router network. Each of the stages of the multi-stage router network may include a plurality of routers. The method may also include detecting that the number of available connections falls below a threshold number. A notification can be sent to one or more routers in a third stage of the multi-stage router network that the router in the first stage is deprioritized. The one or more routers in the third stage can be operated so that communications to the first stage are routed to one or more other routers in the first stage.
