In this work, we investigate overlapping shared segment protection under continuous and TDM-mode sliding scheduled traffic model and compare its performance with that of shared path protection under sliding scheduled traffic model in Store-and-Transfer WDM Networks. Simulations show the following: Under continuous sliding scheduled traffic model, shared segment protection has 12% lower blocking rate...
We call a WDM network with node storage providing lightpaths for large data transfers the store-and-transfer WDM network and investigate resource provisioning in it under sliding scheduled traffic model, which can decrease blocking by 40%.
For large data transfers, the Store-and-Transfer WDM Network (STWN) provides storage and lightpaths jointly. Constrained delays of the transfers restrict the number of waiting requests, thus the storage size can be limited. For dimensioning of STWN, we propose a method to determine the number of wavelengths and storage size required to satisfy the demand. The demand is given as a load matrix with...
