LightningEdge® Operating System (LE-OS)  

Industry Leadership in Video Multicasting

The LightningEdge Operating System supports a comprehensive set of multicast software services including support for up to 1,024 multicast groups, IGMP Snooping, Broadcast Storm Control, a wide variety of Multicast filtering options, and protection with advanced LE-OS security and Quality of Service capabilities. Multicast service reliability is enhanced with Resilient Multicast Distribution (RMD) for immediate restoration on link failure, improved security by preventing multicast and broadcast Denial of Service (DoS) attacks, and enabling full provision of multicast services with advanced Committed Information Rate (CIR) and Excess Information Rate (EIR) allocations.

LE-OS also supports an innovative, industry-leading implementation of Multicast optimized for video applications. LE-OS ChannelStream TM and StreamCast TM solutions support highly efficient – and affordable -- IP video delivery for off-loading routers and enabling router-less delivery of multicast services. ChannelStream is the most efficient method of broadcasting IP video by pushing the multicast content to any level of the network, rather than using inefficient, centralized routers that can be a bottleneck in the flow of content. StreamCast delivers a similar efficiency for IP video conferencing applications. By maintaining a complete multicast mesh with one or more sources at each mesh node, StreamCast also eliminates the need for a centralized multicast router.
