ETSI TS 103 443-1 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.
