Vivoh Multicast App Documentation


The Vivoh Zoom Multicast solution enables IT Service Delivery Managers to provide a seamless way to scale Zoom Webinars with multicast streaming. The design goal is for Zoom hosts and participants to use the familiar Zoom interface and see the highest quality video possible without disrupting the network. IT Service Delivery Managers are provided with a web-based configuration console that enables them to register authorized Vivoh Zoom Multicast hosts and then associate the appropriate network and messaging resources to their events. Real-time analytics are available to managers and hosts which provide detailed insight and assurance of webinar performance.
