Chattanooga has it, and soon Zagreb may have it too: Yesterday, Hravatski Telecom, the Croatian unit of Deutsche Telekom, demoed its TeraStream network capable of 1Gbps, with a 400Gbps network capacity. Cisco is supplying the network solution, which is based on the IPv6 protocol and provides voice, IPTV and Internet access. As is so often the case with new blazing networks, TeraStream is still in the pilot phase, with user-experience testing in the country's capital carrying into 2013. Those of you who speak Croatian can skip past the break for an explanatory video from HV.
