Abstract:

With coarse switching granularity,circuit switching suffers from high blocking probability,especially when the traffic is bursty.How massive intermediate storage may alleviate traffic blocking in OCS(coptical circuit switching)networks was studied.The relationship between the storage capacity and the traffic burst was introduced,and the improvement of the network performance was verified by the simulation results.The results suggest that burstiness in traffic is indeed harmful to the OCS blocking performance,and can be effectively handled with massive intermediate storage.It also indicates that with different levels of storage support,the network may exhibit different levels of burst smoothing functions and achieve different blocking performance.

Key words: big data transmission, assistive storage, burst traffic, optical circuit switching
