Abstract
Distributed denial-of-service attacks are a serious threat to the stability and availability of the Internet. Several traceback schemes are available to mitigate these attacks. Along with several IP traceback schemes, a latest one is the DGT in which the tracking is relying on geographical information. Segment direction ratios (SDR) a novel scheme to overcome the directional limitations of 23 DGT is proposed. This scheme is generalized to 2n DGT (n = 4).The concepts of DR, DRS and NDRS at a Router point is introduced based on uniqueness theorem. Three dimensional, multi-directional geographical traceback, using direction ratio algorithm (DRA) is proposed to remove the limitations. To overcome directions, dimensions and storage space deficiency, three dimensional multidirectional geographical IP traceback direction ratio sampling algorithm (DRSA) traceback is proposed.
