Multicore communications processors have become the main computing element in Internet routers and mobile base stations due to their flexibility and high processing capability. These processors are designed and equipped with enough resources to handle peak traffic loads. But network traffic varies significantly over time and peak traffic is observed very rarely. This variation in amount of traffic gives the users an opportunity to save power during the low traffic times. Existing power management schemes are either too conservative or are unaware of traffic demands.
