Lessons from load balancers and multicast

In general I dislike operating load balancers and IP multicast: I’m a network engineer. Load balancers and IP multicast are very complicated, have a large amount of state, and they are hard to understand and debug. They lead to a lot of operational issues…

”Observation, not old age, brings wisdom” — Publilius Syrus

In the time that we have both collectively spent in the industry, one on the vendor side and the other on the operator side, one of the lasting impressions on both of us is the paucity of tools that a network…

Gaining Intuition with Network Designs

I care a lot about network design. I think it’s too hard to design networks well and I think that all the tools necessary to do it well don’t exist. At least I haven’t seen them. The lack of tools affects the biggest networks, but it affects all networks. I am…
