As software defined networks (SDN) grow in size and in number, the problem of coordinating the actions of multiple SDN controllers will grow in importance. In this paper, we propose a way of organizing SDN control based on coordinated subgraph shadowing. Graphs are a natural way to think about and describe SDN activity. Subgraphs provide a means to share a subset of a network's resources. Shadowing provides a means to dynamically update shared subgraphs. Leveraging advances in graph databases and our shadowing messaging technique, we discuss our implementation of a multi-domain virtual private network (VPN) using multi-protocol label switching (MPLS).
