<b>Title:</b> Energy-Aware Adaptive Network Resource Management<br>
<br>
<b>Abstract:</b><br>
Resource over-provisioning is common practice in network
infrastructures. Coupled with energy unaware networking protocols,
this can lead to periods of resource under-utilisation and constant
energy consumption irrespective of the traffic load conditions.
Driven by the rising cost of energy – and therefore OPEX – and
increasing environmental consciousness, research in power saving
techniques has recently received significant attention. Unlike the
majority of previous work in the area, which has focused on
centralised offline approaches, we propose an online approach by
which the capacity of the network can be adapted in a decentralised
fashion. Based on the modular architectures of modern IP routers,
adaptation is achieved by configuring individual line cards to enter
sleep mode. Re-configuration is performed periodically by
intelligent ingress nodes that coordinate their actions in order to
control the traffic distribution in the network, according to the
actual demand. The approach is evaluated using real network
topologies and traffic traces under different load conditions.<br>
