The Cisco IPTV SLA Solution for IP NGN Video Networks
Monitoring and Troubleshooting Solution for Service Provider IPTV Transport Networks
Executive Summary
Consumers of entertainment-grade video have high expectations of virtually perfect video quality.
As service providers migrate their video content distribution to IP networks, there is an implicit
need for tools that improve operational efficiency, increase network visibility, and help ensure a
smooth migration from providers’ current video networks. The Cisco
®
IPTV SLA solution provides
monitoring of the IPTV broadcast flows through the IP network and delivers quality measurements,
channel mapping, and route path analysis. It is the industry’s first solution that couples the
intelligence of the multicast protocol with the video channel lineups in a monitoring system.
Moreover, it provides rapid problem isolation by offering a common platform for network and video
operators.
With the IPTV SLA solution, network operators can quickly resolve video anomalies by isolating
the issue to a particular portion of the IP network. The operator can see both the scope and the
impact of network problem before the subscriber reports it. The IPTV SLA solution can be
deployed in any video distribution network including wireline IPTV, cable, mobile, and satellite IP
video networks.
Challenge
Service providers have been deploying next-generation IP networks to deliver converged IP
services, with new features for subscribers, at reduced operational costs. However, the delivery of
IPTV content poses some challenges: Errors can occur in the encoding and transcoding process,
and the transport of IP packets across the network can contribute to video impairments. From the
network perspective, IPTV is sensitive to both loss and excessive jitter in the IP network. These
issues can lead to video anomalies visible to the IPTV subscriber as pixilation, picture freeze, or
loss of picture. Today when anomalies are reported by the IPTV subscriber, the network operators
have to associate the video content with the corresponding IP transport infrastructure and spend
time correlating customer calls to troubleshoot the network. As a result, the service provider may
experience long outage periods and higher operational costs associated with troubleshooting
subscriber calls.
The IPTV SLA solution provides the network operator with visibility into both the IPTV multicast
and video control planes, delivering video-quality measurements as well as IP transport statistics
on a per-channel basis.
