Clustering for centralised streaming, Kasenna

Dr Satish Menon, Chief Technology Officer, Kasenna Inc.

Commercial video on demand (VoD) systems require the ability to scale economically in terms of number of users supported (stream capacity) as well the amount of content managed by the system (storage capacity). The approach in the past has been to use proprietary or specialized hardware servers to solve the scalability problem. Such a solution does not take advantage of technology improvements (and the cost reductions that come with it) that are the norm in the main stream computing world (as evidenced by the continuing applicability of Moore’s Law).

Kasenna’s approach to cost-effective scalability is rooted in the philosophy of employing mainstream components (off-the-shelf servers) and innovative software solutions to achieve scalability. In this paper, we describe how Kasenna’s software solutions are engineered to scale video server systems deployed in centralized or decentralized network architectures.
