| Making different video systems interoperable Following our recent coverage of video over IP and telepresence, we heard in a follow-up interview from Bob Romano, VP of Marketing at Radvision, about progress to make different video systems interoperable. Radvision ... IPV conferencing: Bandwidth and quality Continuing our discussion about IP Video (IPV) as a carrier's managed VPN feature, we heard back from Neil Davies, Chief Scientist at Predictable Network Solutions. His company is a consultancy that provides tools and technology to help service provides better manage their networks. IPV over an IP-VPN Following our recent newsletter focus on IP Video, we heard from one of our readers with some excellent questions about IPV over an IP-VPN. He asked, "What would you say were the challenges inherent in adding video to an IP VPN that is already set up for data and voice? Some ISPs offer VoIP convergence with data over an IP VPN but not many offer video too. I would have thought that many industries would welcome the addition of video conferencing over their VPN as a way of saving time and money going to meetings. Is there a reason why this is not being offered as an add-on service?" Why VoIP and IPV should be managed on the same platform Today, we'll focus again on video over IP (or what we call IPV) based on a recent discussion with Psytechnics about the deployment parallels we find between IPV and VoIP/IP Telephony. Psytechnics VP Marketing Joe Frost shared his thoughts on why VoIP and IPV should be managed on the same platform using common tools and evaluative metrics like MOS (Mean Opinion Score), along with some of the challenges in a common approach to session management. 2009 marks tipping point for IP video This week, we turn our focus back to video over IP (or what we call IPV) starting today with some insights provided by Vince Graziani, CEO of VBrick Systems. VBrick started to offer IPV in 1997, and has over 60,000 video appliances and products installed with over 5,000 customers. In a recent interview, Graziani shared his views about the increasing need to engineer corporate networks for video first and data second. He also shared a user case story to illustrate the business case for IPV. 2009 will be the year of IP video One of our predictions for 2009 was that the B2B demand for video over IP would grow this year. We'd like to expand on the topic and will look to cover IP video more extensively this year. This week, we'll begin with a few definitions, throw in a few data points about the growth of IP video, discuss business video encounters experienced in person, follow up with some viewpoints from Cisco and AT&T, and finally we'll sprinkle in our usual analysis and observations.
