Application-Aware Traffic Control for network-based data processing services

Complex Event Processing (CEP) is a key technology for processing of data, the use of which has increased rapidly in recent years. Network service providers are expected to offer new services through network connectivity between distributed devices as data source, data processing systems like CEP and users of the final results. Reduction of the peak traffic is one of the important issues for the network service providers. Because the amount of the capital investment for the network equipments is proportional to the amount of the peak traffic in network. We developed Application-Aware Traffic Control (AATC) for network based data processing services. AATC controls traffic for data processing services based on requirements of users of data processing results and reduces the peak traffic. We will also show the effectiveness of AATC with simulated systems.

FWM crosstalk suppression using wavelength grouping in 25-GHz-spaced 10Gbps-based WDM transmission over NZ-DSF in C-band

We have proposed a novel wavelength grouping method which effectively suppresses FWM crosstalk with a minimum sacrifice in transmission capacity. A 1.36-Tbps WDM transmission employing this method was demonstrated over an enhanced LEAF in the C-band.
