CableLabs interop demos IPv6 voice calls

Plenty of action recently around IPv6: CableLabs hosted an interop event in which participating companies completed voice calls on an IPv6 network; meanwhile, the SCTE formed a working group that will help network operators plan for and deploy IPv6.

At the interop that CableLabs hosted at the end of September, two separate calls involving IPv6 interoperability were completed, one demonstrating the ability to accomplish calls entirely within the IPv6 domain, and the other demonstrating the ability to bridge an IPv6-based device with an IPv4-based device.

The two calls included:

  • A PacketCable 2.0 SIP call between a PacketCable 2.0 embedded digital voice adapter (EDVA) and session border controller (SBC) over IPv6
  • A PacketCable 2.0 SIP call between an IPv6 EDVA and IPv4 embedded multimedia terminal adapter (EMTA).

Participating companies included: A10 Networks, Alcatel Lucent, Arris, Broadcom, Casa Systems, Cisco Systems, Ericsson, GenBand, Huawei, Incognito Software, Intel, Juniper Networks, LG Electronics, Motorola, Netgear and ST Microelectronics.

The range of products involved included DOCSIS 3.0 cable modems, DOCSIS 2.0+IPv6 cable modems, cable modem termination systems, PacketCable EDVAs, e-set-top boxes, provisioning servers, home gateways, consumer electronics devices and carrier-grade NAT servers.

Participants also tested DOCSIS and PacketCable IPv6 provisioning; Internet video streaming; eRouter and standalone home router configuration; and interoperability with consumer electronics equipment and PCs running Windows XP, Windows 7, Mac OS X and Linux. In addition, suppliers tested NAT444 and Dual-Stack Lite, two important IPv4/IPv6 coexistence technologies.

SCTE WORKING GROUP
Separately, the SCTE's new IPv6 Deployment Working Group plans to share information and best practices on device management and service enablement in an IPv6 environment.

The group will address the impact of IPv6 on management of DOCSIS devices, service enablement, voice and video services, and other topic areas.

Initial members of the IPv6 Deployment Working Group include: Arris, Bright House Networks, Comcast, D-Link, Rogers Communications and Time Warner Cable. The forum is open to all SCTE members.

"The challenges of implementing IPv6 are far outweighed by the feature benefits that the new protocol will bring to our industry," said John Jason Brzozowski, chief architect for IPv6 and distinguished engineer for Comcast. "We anticipate that the collaborative exchanges among members of the IPv6 Deployment Working Group will significantly streamline the transition to IPv6 for cable operators, vendors and – most importantly – our customers."
