Ballot Text

Technical Summary

   This document identifies and describes the requirements for a set of
   use cases related to network resiliency on Segment Routing (SPRING)

Working Group Summary

 This draft has been discussed in the WG, with WG comments included 
 in the revision of the draft. Most of discussions were around the path 
 protection use case text. All comments have been correctly addressed by 
 the authors leading to a better text that have consensus.

Document Quality

 This document is an old document, and some use cases described already 
 have implementations today.  As part of the original spring WG charter use
 cases were defined -- the AD requested the WG to not publish the use cases
 and focus on the solutions (architecture, etc.), but the WG reached consensus
 wanting to still publish.
