Next-Generation Techniques to Protect and Secure Realtime IP Media Transport

Chin Chye Koh

Few in the professional video community foresaw Internet Protocol's (IP's) rapid ascent to its position as a dominant (if not the dominant) video transport protocol. To many, IP lacks the control and protection so critical to video networking. While today's IP network infrastructure— driven by the speed and capacity requirements of data centers and cloud-based services—is capable of carrying professional video in a controlled, useable manner, significant concerns remain for the best way to control, monitor, and protect services in wide-area routed networks. — In any media delivery system, there is always concern about network availability and the possibility of outages. The flexibility of IP over Ethernet transport, advanced field-programmable gate array and memory technology, and efficient, low-cost Ethernet switches and IP routers, make it possible to deliver new protection algorithms. With these new algorithms, the highest level of quality of service can be delivered, ensuring minimal outages even in the case of partial network path failures. This paper focuses on recently developed techniques for realtime dataflow protection undergoing trials and initial deployment. These techniques make use of dual launch of network feeds with intelligent buffering and dynamic control.
