Intra-domain IP traceback using OSPF
André O. Castelucio, Antônio Tadeu A. Gomes, Artur Ziviani, Ronaldo Moreira Salles · 2009
Denial of service (DoS) attacks are a serious threat to the appropriate operation of services within network domains. In this paper, we propose a system that creates an overlay network to provide intra-domain IP traceback to deal with this threat. The main contribution of our proposal with respect to previous work is its ability to provide partial and progressive deployment of the traceback system throughout a monitored network domain. We build the overlay network using the OSPF routing protocol through the creation of an IP traceback opaque LSA (link state advertisement). We also investigate and evaluate the performance of partial and progressive deployment of the proposed system, showing its suitability even for large network domains.
