Traffic grooming is concerned with the design, operation, and control of networks with multigranular bandwidth demands. As the number of resources in a multigranular network increases rapidly with the network size, wavelength capacity, and load, a scalable framework for managing these entities becomes essential. Hierarchical traffic grooming facilitates the control and management of multigranular...
This paper develops a novel network protection scheme that provides guarantees on both the fraction of time a flow has full connectivity, as well as a quantifiable minimum grade of service during downtimes. In particular, a flow can be below the full demand for at most a maximum fraction of time; if after a network failure the flow is below its full demand, it must still support at least a fraction...
