The flow aggregation scheme which aggregates a large number of finer-grained services into one large flow can save transceivers and improve spectrum efficiency. It ensures that all services in the aggregated flow have a same routing. Moreover, the spectrum allocated to all finer-grained services in the aggregated flow is continuous. Compared with independent transmission scheme which conducts the...
We propose an inter-core crosstalk-aware routing, spectrum and core allocation scheme with spectrum bands and spatial Sp-Chs in multi-dimensional optical networks to get higher SE and lower XT. 15% reduction in XT is achieved.
Middleboxes are adopted to enhance network functions, e.g., providing security and guaranteeing performance. Some applications require flows to sequence through several middleboxes, and such stateful policy routing is challenging for network administrators. The goal of the management is to distribute well middlebox resources and avoid overloads, thus protecting networks from malfunctioning. Furthermore,...
