1.  Introduction

   As one of the 3 operators in China, China Telecom not only provides
   voice, household broadband and mobile services to public customers,
   but also provides leased-line, VPN, IDC and cloud computing services
   to enterprise customers.  Up to now, the quantities of mobile users
   and household users have reached to 308 million and 123 million
   respectively, of which 267 million are LTE/4G users.  With the
   evolution of mobile networks, China Telecom has begun to provide SA-
   based 5G services.  In addition, China Telecom also provides oversea
   services in some regions, for instances, North America, Europe and
   Australia, etc.

   To support the services provisioning for tremendous amount of users
   in different scenarios, a large-scale IP infrastructure has been
   setup and operated.  This document presents IPv6 deployment in the
   large-scale IP infrastructure of China Telecom, including its
   history, deployment strategy, measurements and challenges.

2.  Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in BCP
   14 [RFC2119] [RFC8174] when, and only when, they appear in all
   capitals, as shown here.

3.  Retrospection

   China Telecom's IPv6 work can trace back to 2001, considering that
   IPv6 is the future of IP network and IPv4 address will be exhausted
   sooner or later, China Telecom begun to test IPv6 over ADSL network,
   and successfully tunneled through the workflow of IPv4/IPv6 dual-
   stack service in broadband network then.
