Decision support queries that scan large indexes can suffer significant degradation in I/O performance due to index fragmentation. DBAs rely on rules of thumb that use index size and fragmentation ...
Abstract: This paper evaluates Spatial Division Multiplexing in Elastic Optical Network (SDM-EON) defragmentation scenarios and applies a combined push-pull and fast-switching defragmentation ...
Abstract: In elastic optical networks (EONs), a major obstacle to using the spectrum resources efficiently is the spectrum fragmentation. In the literature, several defragmentation approaches have ...
