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.
