Abstract

   This draft briefly describes the TRILL's directory assistance
   components. The intent of the draft is to identify the gaps
   against NVO3's Control Plane requirement. Through the gap
   analysis, the document provides a basis for future works that
   develop solutions for Network Virtualization Authority (NVA).

1. Introduction

   This draft briefly describes the TRILL's directory assistance
   components. The intent of the draft is to identify the gaps
   against NVO3's Control Plane requirement. Through the gap
   analysis, the document provides a basis for future works that
   develop solutions for Network Virtualization Authority (NVA).

   Section 4.5 of [nvo3-problem-statement] describes the back-end
   Network Virtualization Authority (NVA) that is responsible for
   distributing the mapping information for entire overlay system.

   There are some similarities between TRILL [RFC6325] and NVO3,
   e.g. TRILL using TRILL header to achieve overlay, vs. NV03 using
   L3 headers plus VNID to achieve overly.  This draft analyzes the
   TRILL directory assistance components that are applicable to
   NVO3's NVA and summarize the gaps.
