LISBON, Portugal, August 17th, 2011 -- Cisco today announced that ZON Multimedia has deployed the Cisco® Carrier-Grade Internet Protocol version 6 (CGv6) Solution to handle the transition of its Carrier Ethernet network to IPv6. The Portuguese cable operator has worked closely with Cisco to drive the activation of IPv6 features in its access, aggregation and Internet peering networks to implement a transparent end-to-end IPv6 infrastructure.

Highlights/Key Facts

  • Support for IPv6 using a dual-stack network (allowing both IPv4 and IPv6 to coexist) will allow ZON to offer enhanced IPv6-ready services to its customers while maintaining customer satisfaction by allowing them transparent usage of both protocols during the transition period.
  • ZON customers can select the time of their choosing to utilize the almost unlimited number of IP addresses enabled with IPv6. This infrastructure provides support for IPv6 with advanced network capabilities, address space expansion, device mobility support and easier device operation.  The new network will provide a strong foundation for meeting ZON's present and future business services requirements.Cisco has a broad portfolio of switches, routers and security devices that have passed international IPv6 testing (see "IPv6-ready logo") as part of its CGv6 portfolio. CGv6's simple framework helps preserve existing investments in IPv4, and prepares for IPv6 with varying transition techniqueswhile helping service providers to prosper during the migration.
  • The Cisco infrastructure deployed in ZON is based on a Cisco Internet Protocol Next-Generation Network (IP NGN) architecture  using the Cisco ASR 9000 Series Aggregation Services Routers as a point of convergence for all CMTS equipments such as the Cisco uBR10000 CMTS (Cable Modem Termination System) loaded with the latest generation line cards, namely the Cisco MC-20x20.
  • ZON is taking its leadership in cable broadband home access to a worldwide level. ZON's customers will be able to benefit from this implementation through ubiquitous Internet access and content availability in both IPv4 and IPv6.

"We have been making smart investments in our network to be able to reach this day. Our innovative network and Cisco's technology has allowed us to offer the most compelling Internet applications. Now we can offer our customers an enhanced and improved experience during Internet surfing."

  • Mark Townsley, fellow at Cisco

"It is critical that service providers have the support necessary to see IPv6 deployed to users before the lack of IPv4 addresses stifles the growth and evolution of the Internet. Cisco is extending its IPv6 leadership with new solutions that enable customers to accelerate the transition from IPv4 to IPv6 with ease. The solution now offered by ZON will allow their users to be connected to the next-generation IPv6 Internet with an abundance of addresses far surpassing what is available in IPv4 today."
