US 2020/0403869 A1 · 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.

Claims20

Dependent claims

A method for programming a network device, comprising:

receiving a class modification batch directed to performing policy in-place updates on the network device;
obtaining a final target class sequence from updating an initial target class sequence based on the class modification batch;
generating an operation commit sequence based on the final target class sequence;
and
performing, based on the operation commit sequence, the policy in-place updates on the network device by committing the class modification batch thereon.

2 more elements

A non-transitory computer readable medium (CRM) comprising computer readable program code, which when executed by a computer processor residing on a network device, enables the computer processor to:

receive a class modification batch directed to performing policy in-place updates on the network device;
obtain a final target class sequence from updating an initial target class sequence based on the class modification batch;
generate an operation commit sequence based on the final target class sequence;
and
perform, based on the operation commit sequence, the policy in-place updates on the network device by committing the class modification batch thereon.
