Next-Generation Techniques for the Protection and Security of IP Transport

Few in the professional video community foresaw 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 now 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 on network availbity and the possibility of outages. With the flexibility of IP/Ethernet transport, advanced FPGA / memory technology, and low cost / efficient Ethernet switches and IP routers, we are now able to deliver new protection algorithms. With these new algorithms, the highest level of Quality of Service (QoS) can be delivered ensuring minimal outages, even in the case of partial network path faliures. This paper will focus on recently-developed techniques for real-time data flow protection now undergoing trials and initial deployment. These techniques make use of dual-launch of network feeds with intelligent buffering and dynamic control.
