Description

This presentation discusses blackhole detection in packet networks. Such blackholes are typically difficult to detect, and even working out on which router the blackhole is occurring can be difficult. We discuss two methods for detecting blackholes: indirect detection and direct detection. We describe a method for a router to report packet drops due to blackholes via IPFIX, including the reason for the drop and associated metadata. This makes the existence of a blackhole much more apparent to the operator and the control systems, thus greatly reducing the detection time. The scheme is equally applicable to IP, MPLS and Layer 2 traffic.
