| Summary: | The power consumption of the network equipment
has increased significantly and some strategies to contain the
power used in the IP network are needed. Among the green
networking strategies, the virtualization class and in particular
the deployment of migrating virtual routers can lead to a high
energy saving. It consists in migrating virtual routers in fewer
physical nodes when the traffic decreases allowing for a power
consumption saving. In this paper we formulate the problem of
minimizing the power consumption as a Mixed Integer Linear
Programming (MILP) problem. Due to the hard complexity of
the introduced MILP problem, we propose a heuristic for the
migration of virtual routers among physical devices in order to
turn off as many nodes as possible and save power according to
the compliance with network node and link capacity constraints.
We show that 50% of nodes may be turned off in the case of a
real provider network when traffic percentage reduction of 80%
occurs. Finally we also perform a feasibility study by means of an
experimental test-bed to evaluate migration time of a routing
plane based on QUAGGA routing software. |
