Impact of path granularity and operation interval on dynamic path network control

The recent advances in network control technology such as GMPLS enable us to dynamically manage path connections with different granularities through a unified control interface, which can improve network resource utilization. In this paper, we investigate the effect of path granularity and operation interval on dynamic path network operation with the aim of minimizing unused bandwidth and the frequency of control actions. We develop a simple technique that applies low-pass filters to the varying Internet traffic; we show that Internet traffic streams captured in different environment exhibit a common trend with regard to Internet traffic parameters.
