Traffic volume anomalies refer to apparent abrupt changes in time series of traffic volume, which can be propagate through the network. Detecting and tracing anomalies is a critical and difficult task for network operators. In this paper, we first propose a traffic decomposition method, which decomposes the traffic into three components: trend component, autoregressive (AR) component, and noise component...
Optical burst switching (OBS) is a promising switching technology for the next optical transport network. In this paper, we analyze the assembled traffic of the science information network (SINET) by using the fractional Brownian motion (FBM) model. The analytical results show that the general timer-based assembly scheme can not avoid increasing the burstiness (variance in short timescales), which...
Burst assembly at edge nodes is an important issue for the optical burst switching (OBS) networks because it affects the traffic characteristics and has an influence on the burst loss performance. By applying the fractional Brownian motion (FBM) model, we find that the timer-based and threshold-based assembly algorithms could not avoid increasing the traffic variability of the science information...
