A measurement study of persistent forwarding loops on the Internet

In this paper, we present a measurement study of persistent forwarding loops and a flooding attack that exploits persistent forwarding loops. Persistent forwarding loops may share one or more links with forwarding paths to some hosts. An attacker can exploit persistent forwarding loops to overload the shared links and disrupt Internet connectivity to those hosts.To understand the extent of this vulnerability, we perform extensive measurements to systematically study persistent forwarding loops. We find that persistent forwarding loops do exist in the Internet. At least 35 million addresses experience persistent forwarding loops, and at least 11 million addresses can be attacked by exploiting such persistent forwarding loops. In addition, 87.4% of persistent forwarding loops involve routers in destination domains, which can be observed from various locations. This makes it possible to launch attacks from multiple vantage points. We also find that most persistent forwarding loops are just two hops long, which enables an attacker to significantly amplify traffic to them.We further investigate the possible cause of persistent forwarding loops, and find that about 50% of them are caused by neglecting to configure pull-up routes. We show that even if the misconfiguration occurs in a stub network, it may cause persistent forwarding loops involving routers in large ISPs, and can potentially be exploited by attackers to flood links in a backbone network. To the best of our knowledge, this is the first study of exploiting routing misconfigurations to launch DDoS attacks and understanding the impact of such attacks.

Self-healing routing: failure,modeling and analysis

Network failures occur frequently, and self-healing ability of existing routing protocols cannot guarantee fast route convergence under these failures without impacting packet forwarding. During routing convergence, network routes may be incorrect and even routing black holes and loops occur, which will result in extensive packet loss and thus influence network performance. To solve this problem, several improved routing solutions have been proposed. In this paper, we propose the concept and model of self-h...

Mitigating transient loops through interface-specific forwarding

Under link-state routing protocols such as OSPF and IS–IS, when there is a change in the topology, propagation of link-state advertisements, path recomputation, and updating of forwarding tables (FIBs) will all incur some delay before traffic forwarding can resume on alternate paths. During this convergence period, routers may have inconsistent views of the network, resulting in transient forwarding loops. Previous remedies proposed to address this issue enforce a certain order among the nodes in which they update their FIBs. While such approaches succeed in avoiding transient loops, they incur additional message overhead and/or increased convergence delay. We explore an alternative approach, loopless interface-specific forwarding (LISF), that mitigates transient loops by forwarding a packet based on both its incoming interface and destination address. LISF needs to compute and update interface-specific instead of interface-independent forwarding tables. But it requires neither the synchronization of FIB updates at different nodes nor the modification of the existing link-state routing mechanisms. LISF is easily deployable with current routers if they already maintain a FIB at each interface for lookup efficiency. This paper presents the LISF approach, illustrates its strengths and limitations, discusses four alternative implementations of it and evaluates their performance.
