Abstract

See full text

A method for remote triggered black hole filtering can include advertising a first modified next hop address for a destination address of network traffic, and advertising a second modified next hop address for a source address of network traffic. The first next hop address of the destination address might be overwritten with the first modified next hop address. Filtered traffic then can be forwarded to the first modified next hop address, wherein filtered traffic comprises only network traffic addressed to the destination address or from the source address. In some cases, the filtered traffic is transported and received via a sinkhole tunnel. A second next hop address of the source address can be overwritten to a second modified next hop address. The attack traffic, which can be filtered traffic that is both addressed to the destination address and from the source address, might be forwarded to a discard interface.
