Method and network device for enabling in-place policy updates

Abstract:

A method and network device for enabling in-place policy updates. Specifically, the method and network device disclosed herein entail effecting the removal and/or insertion of policies on the network device while minimizing a window in which active policies may be disrupted by the policy updates. Further, in-place policy updates call upon the ordered-shifting of content stored across data structure elements. Through ordered-shifting, policy updates can utilize limited memory resources, on the network device, more efficiently over existing methodologies. Additionally, policy updates can also be committed faster, thereby allowing more policy updates to be processed with a fixed time window.
