Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Integrated broadband cable telecommunication networks (CABLE). The present d

4、ocument produced for the transition technologies accommodates an urgent need in the industry to define requirements that enable seemless transition of Cable Networks to IPv6. Considering the depletion of IPv4 addresses, transition to IPv6 is required in order to enable continued growth of the custom

5、er 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. A plethora of transition technologies have been proposed in IETF, other standar

Each of these technology options is specified, implemented and deployed in various forms and stages. The present document is based on the requiremen
