The IP over optical (IPO) network is becoming one of the most interesting among all proposed models of transport networks nowadays. In an IPO network, the reconfiguration capability of the network could be used in order to balance the load of its network elements (NEs). Reconfiguration operations (i.e., switching in OXC nodes and rerouting in IP routers) take place in real-time. Consequently, intensive changes in NEs settings might cause failures in the existing connections in the network. For that reason, changes in Nes settings should be coordinated in a reconfiguration process. In this paper, the author has proposed an optimization method for such reconfiguration process. The mathematical model of the method including computation results has been presented.
