Kasenna at TelcoTV today unveiled its streaming video-on-demand (VOD) technology that enables service providers and cable operators to cut deployment and management costs for triple-play services.
Kasenna says the cluster can power a half-million subscriber deployment from one video head office using MPEG-4 streams encoded at 2.5mbps. The benchmark tests used 12 dual processor servers based on the 64-bit Intel Xeon processor (3.4GHz) powered by Kasenna MediaBase version 8.1 software that incorporates hybrid RAM/Disk streaming. The tests achieved 144gbps of streaming capacity, which equated to 57,600 MPEG-4 streams at 2.5mbps per
stream and 38,400 MPEG-2 streams using 3.75mbps encoding, the company says.
"This benchmark demonstrates that video-on-demand systems can scale to support very large numbers of subscribers with a manageable number of servers," says Bob Larribeau, senior analyst at the Multimedia Research Group. "It shows that riding the curve of mainstream technology development produces high-performance systems for IPTV service providers."
The benchmark was observed under real-world demand conditions using actual traffic from a VOD deployment and all mainstream components. Kasenna's Stream Clustering technology, which incorporates a number of different algorithms for pre-caching, hot-spot measurements, load averaging and request arrival predictions, guaranteed the load balancing among the cluster, the company says.
