Introduction
Considering the depletion of IPv4 addresses, transition to IPv6 is required in order to enable continued growth of the
customer base connected to cable networks and ensure service continuity for existing and new customers. High-quality
connectivity to all kinds of IP-based services and networks is essential in today's business and private life.
The present document accommodates an urgent need in the industry to implement and integrate the IPv6 transition
technologies as specified by ETSI TS 101 569-1 [1] into their cable networks. The choice of the technology
implemented depends on factors such as the business needs, current deployed architectures and plans for cost
effectively transition from IPv4 to IPv6.
Current global IPv4 address space was projected to be depleted around the middle of 2012; depletion for the
operator was estimated around end 2012. As part of the resulting roll-out of IPv6 in the operator's network,
specific measures had to be taken to allow a smooth transition and coexistence between IPv4 and IPv6. ETSI
developed ETSI TS 101 requirements to address transition from IPv4 to IPv6 specifying six transition
technologies as given by ETSI TS 101 569-1 [1] that were at the time considered to be the most appropriate to
assist cable operators to transition there cable networks to IPv6.

Since then the industry has acquired more experience with the technology options settling in the main for
DS-Lite across the cable network market and NAT64 IPv6 transition technologies across the mobile market.
The present document is the final part of a companion of ETSI standards developed in 4 phases to provide the cable
sector in particular cable operators engineering and operational staff a standardized approach when integrating one of
the five IPv6 transition technologies, NAT64, DS-Lite, 464XLAT, 6RD and MAP-E.
The first phase assessed the different IPv6 transition technology options being defined by industry with
recommendation for the most appropriate with consideration of current network architectures, ensuring adequate scale
and a cost effective transition approach from IPv4 to IPv6 as the IPv4 addresses deplete. The objective being to
examine the pros and cons of the IPv6 transition technologies and recommend the most cost effective solution that
would enable the cable operators to minimize the cost of upgrades to their existing network plant whilst maintain
continuity of services to their present and new added customers. The details of the study are given by ETSI
TR 101 569 [i.3].
In the second phase an ETSI TS 101 569-1 [1] was developed to specify technical requirements for six transition
technologies that industry were considering for use by Cable Operators depending on the current state of their deployed
cable network architecture, service model requirements and their IPv6 transition strategy as the IPv4 addresses depleted.
These six IPv6 transition technologies are specified by ETSI TS 101 569-1 [1], covering NAT64, DS-Lite, 6RD,
NAT44, 464XLAT and MAP-E.
In the third phase ETSI developed a series of conformance test specifications to enable the compliance verification of
the five IPv6 transition technologies, NAT64, DS-Lite, 464XLAT, 6RD and MAP-E that were specified during phase 2
standardization. The conformance tests are developed against the requirements given by the ETSI TS 101 569-1 [1].
The series of conformance tests developed for each of the four transition technologies, are as given by, ETSI
TS 103 238 parts 1 [13] to 3 [15] respectively for NAT64; ETSI TS 103 239 parts 1 [16] to 3 [18] respectively for
MAP-E; ETSI TS 103 241 parts 1 [19] to 3 [21] respectively for DS-Lite; ETSI TS 103 242 parts 1 [22] to 3 [24]
respectively for XLAT and ETSI TS 103 243 parts 1 [25] to 3 [27] respectively for 6RD.
Phase 4 is the present project phase for development of technical specifications covering the operational and
engineering requirements with the present document being part 1, general part of a multi-part series presenting general
information relative to each of the transition technologies.

1 Scope
The present document presents the engineering and operational requirements for the application of IPv6 transition
technologies as defined by ETSI TS 101 569-1 [1] (IPv6 Transition Requirements) implemented within an integrated
broadband cable network end to end across its network domains.
The present document is part 1 of a multi-part series and presents a generic view of a typical end to end cable network
when considering the key aspects to engineer and operate the IPv6 transition technology across its network domains.
The technical requirements addressing each network domain relative to the IPv6 transition technology in question is
described in the clauses of the part specific to the IPv6 transition technology.
The operational aspects for the IPv6 transition technologies, NAT64, DS-Lite, MAP-E, 464XLAT and 6RD are
considered when engineered end to end across the cable network domains:
• CPE Home Networking Domain
• Access Network Domain
• Core Network Domain
• Data Centre Domain
• DMZ Service Domain
• Transit and Peering Domain
• Management and Monitoring Domain
• Security Domain
The present document specifies the requirements to be considered when the defined IPv6 transition technology DS-Lite
is engineered across the cable network domains.
