Considering the depletion of IPv4 addresses, transition to IPv6 is required in order to enable continued growth of the custo
5、mer 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 standa

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