A New Solution for the Timing and Scaling of DOCSIS IP Multicast Services

Attendees of next week’s The Cable Show are hoping to catch an early glimpse of tomorrow’s evolution in TV and cable. Next Wednesday morning, ARRIS’s own Tom Cloonan, CTO Networks, will be moderating a session entitled “From CDNs to Streaming Clouds: Advanced Approaches for Video Delivery”. On this panel, Amit Eshet, ARRIS Fellow, will be presenting a paper entitled “Multicast as a Mandatory Stepping Stone for an IP Video Service to the Big Screen” and I will be presenting a paper on entitled “An Improvement Proposal for the Timing and Scaling of DOCSIS IP Multicast Services”.

In my talk, I will address an issue related to a key component of the IPTV evolution: efficient DOCSIS IP multicast delivery.

Consumers’ increasing multiscreen habits coupled with the growing adoption of the DOCSIS 3.0 protocol pose an imminent timing and scalability challenge to many DOCSIS-based IPTV systems—ranging from multicast processing power, membership messaging latency, and unicast bandwidth needs for fast-channel-change techniques.

My co-authors and I believe that the industry can mitigate this challenge by employing a DOCSIS® Multicast Carousel to enable the cable modem to make its own tuning and multicast forwarding decisions.

Our panel takes place Wednesday, April 30 at 8:00 am in Room 403B. We hope to see you there!
