Help Make Complexity Simple!

Network complexity is the primary reason for “catastrophic failures”. Everybody knows stories of massive widespread outages which often cannot be contributed to a single root cause. The post-mortem of each case explains the root causes of this specific case, but it doesn’t help predict future outages, and it doesn’t help understand network complexity in a more generic way. Complexity research specific to "real" networks is currently happening in various fora, for example at RIPE meetings. However, more community effort is needed to progress the research.   This talk is a short call for help: We need people to document and work through cases of “catastrophic failure”, to dissect each case, compare them, and try to find common patterns. We also need help in understanding what makes a network more complex, and how to measure and contain complexity.
