Integrated Video Admission Control for the Delivery of a Quality Video Experience
by Cisco Systems
Published 2006; Posted November 2006


Abstract:


Cisco works closely with service providers on Cisco IP NGN technologies to ensure that video reaches users with high quality, based on policies administered in the network’s service layer. Given the bandwidth demands and quality requirements of video services, Cisco developed an admission-control solution that consists of two highly reliable components: video-on-demand (VoD) admission control and broadcast video admission control.

 

Performing admission control is necessary to preserve a high-quality video experience. The Cisco admission control solution takes into account complex network topologies that have redundant and load-sharing paths in the transport network as well as access link utilization policies and business policies that may be enforcing other constraints on subscriber services. Cisco admission control solution can differentiate between paid VoD, free VoD, specific high-demand broadcast channels, and many other variables, giving service providers enhanced choice and control over the IPTV experience. Cisco routers, in coordination with the Cisco Broadband Policy Manager (BPM) and on-demand servers and managers, perform the Integrated Video Admission Control function collectively.
