Nippon Telegraph and Telephone corporation (www.ntt.com) which is a Japan based communication provider has developed a new technology that facilitates the on demand transmission of gigabit- class video transmission. It is a successfully proven on a testbed network from NICT and NTT. According to the announcement on Tuesday, NTT verified it’s achievement in a wide area experiment in co operation with the National Institute of Information and Communications Technology. Using GEMnet2 and JGN2plus, the R&D testbed networks from NTT and NICT, respectively are being used. It lets users to achieve steady transmission of high density video such as HDTV by acquiring a path in the network whenever needed. It does not even allocates additional network resources or reoptimizing the provisioned network resources. There are some plans on demonstrating these results at the upcoming SC09 conference to be held in Portland, Oregon, this week, using an international connection between the test network and the exhibition booth. The NTT labs have also developed i-Visto in the past. It is a technology used to transmit uncompressed video streams through IP networks. It required a large bandwidth of more than a gigabit per second. The users can’t begin the transmission immediately by getting a wait for the network operator for allocation of resources with the transmission path. The use of high speed IP optical networking have made the NTT’s new network technology for setting up large bandwidth circuit in optical network, like video transmission request. The other problem was for the degradation for the quality, which is prevented by use of special equipment for measuring the accuracy of the video stream packets at multiple points in the network. The new PC-based technology by NTT can be placed at many points with the ability in the network to observe any change in the behavior of the video packets—changes which could result in quality deterioration. Under the "Research and Development of Dynamic Network Technology" project, the achievement was sponsored in part by NICT. NTT plans to enhance it’s network and video collaboration in future so as to allow better functionality, such as adaptive control, so that it can be used by broadcasters and other high end users. NTT is hoping that this technology will be used in many other arenas that can benefit from high resolution video, like the fields of telemedicine and e-learning. NTT is going to show it’s latest technology at the SC09 conference. Earlier this week, NTT’s competitor Infinera which is a transmission equipment provider announced it is showing a pre-production 100 Ethernet Module designed to deliver 100GbE services in today's Infinera DTN and over today's network infrastructure.
