Abstract
An apparatus and method routes data over network links based on a temperature of the network links. When the temperature of a link meets a first threshold a routing mechanism re-routes a portion of the network traffic over a lower temperature link to reduce the likelihood that the link will exceed a second threshold that necessitates that the link be throttled back or disabled. Re-routing data to cooler links allows the system to maintain the lowest possible temperature of the network links to gain optimal performance of the system. In the disclosed example, the network links include interconnect cable connections and backplane connections. A temperature of the network links is determined by monitoring a region of an integrated circuit near a line driver driving the network link.
