Real-Time Performance Analysis of Adaptive Link Rate
High speed links are widely deployed in modern day computer networks to meet the ever growing needs for increasing data bandwidth. However, with the increase in the link rate, the power consumption of the network interfaces increases exponentially, compounding growing concerns about network power consumption. Fortunately, network traffic characteristics show that rapid link rates are not always required. During times of reduced network traffic, the Adaptive Link Rate (ALR) mechanism allows link rates to be reduced with little impact on network performance.
