NTT's Video Tunnels
The development sounds like some kind of video transport nirvana. "With this advancement, users can achieve steady transmission of high-density video such as HDTV by acquiring a path in the network whenever it is needed, without allocating additional network resources or re-optimizing the provisioned network resources," states NTT.
The carrier says it has tested the system with Japan's National Institute of Information and Communications Technology (NICT), and that it intends to show off its "synergy of video applications and IP-optical networking" at the upcoming SC09 event in Portland, Oregon (November 14-20).
NTT says current systems for the transport of uncompressed video, which requires "bandwidth of more than a gigabit per second," aren't capable of real-time network asset provisioning, and that the level of monitoring needed for video "requires special equipment that is too expensive to distribute to many points in the network."
The Japanese carrier says it's "planning further enhancements to network and video collaboration that will allow greater functionality, such as adaptive control, so that it can be employed by broadcasters and other high-end users. Furthermore, our aim is for this technology to eventually be used in many other arenas that can benefit from high-resolution video, including telemedicine and e-learning."
The point here, it seems, is that having technologies that can provide lots of bandwidth isn't enough -- the real pain points are in the network and service operations, in this case the provisioning and service assurance. And as long as operators like NTT feel they can't source the capabilities they need from the vendor community, they're going to crack on and develop them in their own labs, something at which NTT appears to be rather good: It recently won a Light Reading Top Pick award, in the IP Applications category, for its ongoing work on IMS (IP Multimedia Subsystem).
