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 c
18、ontinuity 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 accommodates an urgent need in the industry to implement and integrate the IPv6 transition technologies as specifi
19、ed 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 arou
20、nd 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 smooth transition and coexistence between IPv4 and IPv6. ETSI developed requirements to address transition
21、 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
22、 settling in the main for DS-Lite across the cable network market and NAT64 IPv6 transition technologies across the mobile market. The objective of the present document is to define the operational and engineering requirements to enable engineers to implement a seamless transition of the cable netwo
23、rks to IPv6 with the application of the MAP-E transition technology. 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
24、of the five IPv6 transition technologies, NAT64, DS-Lite, 464XLAT, 6RD and MAP-E. ETSI ETSI TS 103 443-4 V1.1.1 (2016-08)5 The first phase assessed the different IPv6 transition technology options being defined by industry with recommendation for the most appropriate with consideration of current ne
25、twork 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 opera
26、tors 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.2. In the second phase an ETSI technical specification was developed to specify technical req
27、uirements 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 tec
28、hnologies are specified by ETSI TS 101 569-1 1, covering NAT64, DSLite, 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
29、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 2 to 3 4 respectively fo
30、r NAT64; ETSI TS 103 239 parts 1 5 to 3 7 respectively for MAP-E; ETSI TS 103 241 parts 1 8 to 3 10 respectively for DS-Lite; ETSI TS 103 242 parts 1 11 to 3 13 respectively for XLAT and ETSI TS 103 243 parts 1 14 to 3 16 respectively for 6RD. Phase 4 is the present project phase for development of
31、technical specifications covering the operational and engineering requirements with the present document being part 4 of a multi-part series covering the IPv6 transition technology MAP-E.

ETSI ETSI TS 103 443-4 V1.1.1 (2016-08)6 1 Scope The present document presents the engineering and operational requirements for the application of the IPv6 transition technology MAP-E as defined by ETSI TS 101 569-1 (IPv6 Transition Requirements) 1 implemented within an integrated broa
33、dband cable network end to end across its network domains. The present document is part 4 of a multi-part series and presents the operational aspects of the IPv6 transition technology MAP-E across the cable network domains. Only those elements of the network that have to be engineered to operate the
34、 IPv6 transition technology MAP-E are presented. Descriptions and interface details of network elements that do not change are already addressed by the relevant equipment cable standards and therefore this information is not included in the present document. The conformity of the MAP-E implementatio
35、n is relevant when assessing its implementation and operational requirements across the cable network to ensure the implementation is correctly engineered to conform to the requirements of the base standard ETSI TS 101 569-1 1. These conformance tests are not specified in the present document as the
36、y are already specified by ETSI TS 103 239 parts 1 5 to 3 7. The operational aspects for the IPv6 transition technology MAP-E 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 Se
37、rvice 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 MAP-E is engineered across the cable network domains. 2 References 2.1 Normative references Refere
