Data-driven network connectivity
Abstract: Routing on the Internet combines data plane mechanisms for
forwarding traffic with control plane protocols for guaranteeing connectivity and
optimizing routes (e.g., shortest-paths and load distribution). We propose data-driven
connectivity (DDC), a new routing approach that achieves the fundamental connectivity
guarantees in the data plane rather than the control plane, while keeping the more
complex requirements of route optimization in the control plane. DDC enables faster
recovery from failures and easier implementation of control plane optimization.
