Today's data networks are surprisingly fragile and difficult to manage. We argue that the root of these problems lies in the complexity of the control and management planes---the software and protocols coordinating network elements---and particularly the way the decision logic and the distributed-systems issues are inexorably intertwined.
In this talk, I will first present a measurement study on routing design of today's production IP networks. Motivated by this experience, I will then argue that stepping back and rethinking the problem of network control and management leads to promising alternative. We propose a clean slate re-design of the network control and management system called "4D", after the architecture's four planes: decision, dissemination, discovery, and data. The 4D architecture refactors the network control system, leaving only a thin set of minimal functionality on each router. All of the decision logic is removed from the routers and collected onto servers where the objectives for the network can be explicitly specified and used to directly control the network. Experimental evaluation of a prototype shows that the architecture is feasible and enables new capabilities missing from today's networks.
