Abstract
FlowSpec is a mechanism for distributing rules to routers in a network. Such rules may be used, for example, to drop traffic associated with a distributed denial of service attack. However, a malformed or incorrect FlowSpec announcement may, if distributed in the network, cause legitimate traffic to be dropped, degrading the service experienced by legitimate users. As such, systems and methods for avoiding the distribution of malformed FlowSpec announcements are provided.
