With the ever-increasing demand for online video content propelled by changes in consumer behavior, service providers realize that delivery of multiscreen content is strategically important and core to their business. The 2013 Cisco® Visual Networking Index (VNI) forecasts that Internet video will be 69 percent of all consumer Internet traffic in 2017. The sum of all forms of video - linear TV, Video on Demand (VoD), Internet video, and peer-to-peer video - will be in the range of 80 to 90 percent of global consumer traffic by 2017. This demand raises a challenge to service providers that leads them to deploy and own Content Delivery Network (CDN).
Factors that need to be considered when building CDNs include:
• Growth of IP video traffic and the ability of the video distribution architecture to scale accordingly
• Demand for multiscreen video experiences: managed video content to customer's IP-enabled devices such as PCs, tablets, game consoles, and Wi-Fi-connected mobile phones
• Demand from content providers, broadcasters, and movie studios for a secured distribution of video content to protect copyrights
• Need for advanced service routing and delivery service management
• Low OpEx and TCO
™ Distribution Suite for Internet Streaming (VDS-IS) meets all of these requirements, and augments core CDN capabilities with advanced service routing and content streaming intelligence. Cisco can help service providers take full advantage of CDN technology to reduce costs, deliver amazing multiscreen experiences, and capitalize on the cloud revolution.
™ Distribution Suite for Internet Streaming (VDS-IS) is an integrated system with a network-based architecture that transcends existing streaming solutions. It allows service providers to extend their video-managed content to their customers' IP-enabled devices such as PCs, tablets, game consoles, and Wi-Fi-connected mobile phones by using sophisticated service routing and content distribution intelligence.
Cisco VDS-IS software is installed on Cisco Content Delivery Engine (CDE) appliances as well as Cisco high-performance Unified Computing System
™ (Cisco UCS
®) servers and blades, providing a flexible and cost-effective solution to service providers who plan to build content delivery networks.
