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: Traffic requests are becoming more heterogeneous and dynamic causing the so-called spectrum fragmentation. We propose a reactive defragmentation algorithm to mitigate this issue which ...
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 ...
