Internet-Draft Net2Cloud Gap Analysis July 2020
1. Introduction
[Net2Cloud-Problem] describes the problems enterprises face today
when interconnecting their branch offices with dynamic workloads
hosted in third party data centers (a.k.a. Cloud DCs). In
particular, this document analyzes the available routing protocols
to identify whether there are any gaps that may impede such
interconnection which may for example justify additional
specification effort to define proper protocol extensions.
