Abstract
Systems and methods consistent with the present invention provide a better fragment drop heuristic that determines a per-fragment determined 'remainder time' value to trigger potential drops on the whole bundle. A per-bundle drop timeout value is assumed. This value is to be configured based on differential delay considerations of the various links that constitute the bundle. The arrival time of a fragment to a reassembly algorithm triggers a remainder timer. When the reassembly algorithm instance actually processes the fragment, the 'remainder time,' which is difference of a bundle drop timeout and time elapsed on the remainder timer, is used to determine whether the fragment and the other fragments of the packet should be dropped.
