Introduction Considering the depletion of IPv4 addresses, transition to IPv6 is required

16、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 todays business and private life. The present document accommoda

17、tes 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 effe

18、ctively 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 operators network, specific measures had to be taken to allow a s

19、mooth 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 tran

20、sition there cable networks to IPv6. ETSI ETSI TS 103 443-1 V1.1.1 (2016-08)5 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

21、 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

22、. 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 addre

23、sses 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 pre

24、sent 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

25、 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 de

26、veloped 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 ETS

27、I 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

28、; 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, gener

30、cument 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 pa

31、rt 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

32、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 Network
