Applying statistical multiplexing and traffic grooming in optical networks jointly
Multilayer optical core networks are able to provide huge bandwidth. With traffic grooming we can utilize more efficiently the available resources. The principle of grooming: if the routes of two different traffic flows (or demands) have common links, their traffic can be joined in to the same wavelength channel. Another well-known solution for increased efficiency of resource usage is multiplexing the traffic. The statistical multiplexing does not allocate the maximal bandwidth for each traff ic demand, but less than the maximal and more than the average. The aim of this article is to investigate the effects of applying both solutions.
