The basic algorithm that consistently updates the switches of a Software Defined Network while preserving the update property of per-packet consistency is the two-phase update. The two-phase update is underspecified on two matters: 1) how to detect when the last packet of the old rule set has left the network and therefore exactly when to delete the old(More)
Per-packet consistency (PPC) is preserved, if during an update to a Software Defined Network (SDN), every packet either matches the new rules added or the old rules to be deleted, but not a combination of both. We propose a general update algorithm called PPCU that preserves PPC, is concurrent and provides an all-or-nothing semantics for an update,(More)
