For as long as we can remember, the telecom industry has been talking about a world with inexpensive, easy-to-use videoconferencing available to millions of PCs around the world.\u00a0 Well it just hasn\u2019t happened.\u00a0 Connectivity costs have been too unwieldy and reliability hasn\u2019t always been the best.\u00a0 Equipment costs and ease of use have improved, but without the appropriate business case on the connectivity side it hasn\u2019t mattered.\u00a0 That said, video over IP appears to be creating renewed interest across the industry in making this vision a reality.So let\u2019s take a look at some examples of services that appear to be gaining traction across the industry.\u00a0 We\u2019ll look at three:\u00a0 Glowpoint Networks (Wire One Technologies), Viditel (Santa Cruz Networks) and\u00a0MASERGY .\u00a0 Each of them has addressed the issue a little differently.A network built for video over IPWire One Technologies is a provider of end-to-end videoconferencing solutions with an installed customer base of more than 3,000 companies and approximately 22,000 videoconferencing systems. Services based on its video over IP systems are delivered via the Glowpoint network, which is dedicated to\u00a0H.323\u00a0videoconferencing. The goal of the Glowpoint network is to improve the quality, reliability, and functionality of video communications at dramatically lower network transmission costs.\u00a0 The Glowpoint network was created specifically to support IP to enhance videoconferencing solutions.\u00a0 Another priority for the company was to make videoconferencing work like audio conferencing - in other words, in a way users were familiar with and accustomed to. This entailed call setup, help and billing functionality similar to that of the audio conferencing world.\u00a0 Service packages also include the required equipment.Be the equipment vendor and the service providerSanta Cruz Networks is a provider of real-time Internet communications systems. Its products are designed to enable high-quality, real-time communication featuring one-to-one or many-to-many audio and video, application sharing and instant messaging, over the Internet or any other IP network.\u00a0 The company has a patent-pending technique for providing service performance, security, reliability and simplicity, and presence, directory and billing services are also included in their offerings. To date, Santa Cruz Networks products have delivered over 1.5 billion user minutes worldwide.In order to develop interest in its video over IP solution, Santa Cruz Networks created a service provider to allow users and potential customers to try the service.\u00a0 But the main goal in creating this service provider is to sell network appliance products to "real" service providers so they can enable their own video over IP services. Viditel is one such example.\u00a0 This is a voice and video calling plan that works over broadband for the home or business.\u00a0 Users purchase calling plans similar to what they would in the landline or cellular world -\u00a0 the difference is, these are video calling plans.\u00a0Enable the transportMASERGY is a privately-held global service provider focused on offering businesses predictable, high-quality transport of enterprise applications, including voice and video services.\u00a0 It serves customers in 18 countries throughout Europe, Asia, Latin and North America.\u00a0 Its services leverage\u00a0Multi-protocol Label Switching\u00a0across an IP-based network.\u00a0 MASERGY offers services in three categories:\u00a0 Intelligent Transport, Application Services, and Control Services. Application Services encompass voice and video.\u00a0MASERGY's inCONTROL Video is specifically engineered to deliver guaranteed TV quality videoconferencing (constant 30 fps, synchronized audio\/visual, and zero "tiling") at all times, under all network conditions.\u00a0 This service is backed by a service-level agreement that includes key performance metrics such as:\u2022\u00a0 100% packet delivery. 100% in-sequence packet delivery. Maximum latency variation (jitter) of 10ms. Sub-1 second fast fail-over (network recovery).\u2022\u00a0\u2022\u00a0\u2022\u00a0In summary, video over IP offers end users some options to alleviate historic concerns with videoconferencing:\u00a0 costs, ease of use, reliability. IP-based videoconferencing is here now and is happening; and options exist across the marketplace for all different sizes and types of end users.
