Query: Active Switching: Packet Steering Flow Annotations   Our previous experience building systems for middlebox chain composition and
scaling in software-defined networks has revealed that existing mechanisms of
flow annotation commonly do not survive middlebox-traversals, or suffer from
extreme identifier domain limitations resulting in excessive flow table size.
In this paper, we analyze the structural artifacts resulting in these
challenges, and offer a framework for describing the behavior of middleboxes
based on actions taken on traversing packets. We then present a novel mechanism
for flow annotation that features an identifier domain significantly larger
than existing techniques, that is transparent to hosts traversed, and that
conserves flow-table resources by requiring only a small number of match rules
and actions in most switches. We evaluate said technique, showing that it
requires less per-switch state than conventional techniques. We then describe
extensions allowing implementation of this architecture within a broader class
of systems. Finally, we close with architectural suggestions for enabling
straightforward integration of middleboxes within software-defined networks.
