MediaBase 1000 Series Library Servers, RamBase 1000 Cache Servers and Clustering Technology Power Large-Scale IPTV and Cable VOD Deployments

LONDON– September 12, 2005 – Kasenna, The IPTV Company, today announced that it is now shipping two new video server lines, MediaBase 1000 series Library Servers and RAMBase™ 1000 series RAM Cache Servers. These two systems add to Kasenna’s broad video content delivery and management product portfolio to deliver unrivaled reliability and flexibility to meet the extensive reliability, performance and cost-effectiveness needs of service providers deploying on-demand services for Standard Definition (SD) and High Definition (HD) content. Both servers use 64-bit processes with extended memory architecture Combined with Kasenna’s unique and patented cache propagation technology (US Patent 6,859,840), the servers can be deployed in a central cluster architecture or decentralized network architecture to meet the needs of large-scale IPTV or cable networks. Driving the servers is the latest MediaBase XMP™ v8.1 and vFusion™ v1.2 video network management software.

“As video networks become larger and serve more users with broader libraries of content, it is becoming essential to be able to move content through hierarchies of servers with disk and memory caches that meet specific performance demands at various points in the network,” said Dr. Satish Menon, CTO of Kasenna. “MediaBase 1000 series and RAMBase 1000 series, along with our Stream Clustering™ application-level clustering technology give cable and IPTV service providers the reliability, flexibility, and performance to cost-effectively meet their content distribution needs in networks of any size.”

MediaBase 1000 series configurations include a choice of 1, 2, or 4 TB of content storage per server. A cluster of such servers can be deployed as a redundant library server farm. An eXtended Memory (XM) option allows the 64-bit processors to address large RAM cache, which exploits usage patterns inherent in VOD viewing to effectively double the number of streams that can be delivered from the library itself. RAMBase 1000 series is a 100 percent cache server that uses large amounts of RAM-cache (up to 64 Gigabytes of RAM per building block) and usage patterns inherent in VOD viewing to deliver high-capacity streaming in a rack, together with Library Servers. Application-level Stream Clustering technology performs load balancing of the cluster, effectively monitoring the usage for titles that are suddenly getting popular (hot spots) or servers in a machine that are getting loaded (load skews). A High-Availability (HA) feature provides N+k redundancy support (where up to k machines in a cluster can fail without affecting the capacity of the cluster).

All of Kasenna’s servers support streaming of all standard MPEG formats – MPEG-2, MPEG-4 Part 2 and MPEG-4 Part 10 (also known as H.264 or AVC). This allows operators to protect their investment as they move to higher-efficiency codecs for ADSL or VDSL networks as well as to enable a transition to High-Definition VOD serving.

“These products give our major carrier customers the components they need to create the high performance, cost effective, multi tier content delivery networks they will need in order to deploy, scale, and manage their on-demand video entertainment services,” said Mark Gray, CEO and chairman of Kasenna.
