Abstract
Techniques for implementing hitless network traffic policy upgrades are provided. In one set of embodiments, these techniques allow a hitless upgrade of a network traffic policy to be performed in a manner that guarantees all network packets subject to the policy are evaluated against either the old policy version or the new policy version. Accordingly, these techniques avoid scenarios where some network packets fail to be evaluated against the traffic policy at all during the hitless upgrade process (which can result in incorrect forwarding behavior).
