Abstract
Methods and arrangements for verifying controller actions in a clustered software defined network. A contemplated method includes: intercepting at least one message at the primary controller; wherein the at least one intercepted message comprises a message that induces one or more changes in the network; intercepting at least one cache update in the network; replicating the at least one intercepted message and the at least one cache update; directing the at least one replicated message and the at least one replicated cache update to a verification subsystem; and verifying the at least one replicated message and the at least one replicated cache update in the verification subsystem. Other variants and embodiments are broadly contemplated herein.
