Cisco ANA detects faults related to transport network elements (such as CPU overload
or link flaps) and escalates them to Cisco Info Center.
●
Cisco Info Center correlates alarms to impacted channels—the operator sees on the
service dashboard that the channel showing the playoff game is in error.
●
Operator filters to the alarms associated to this channel and cross-launches Cisco Multicast
Manager to trace the network path for the individual channel from the ballpark in St. Louis
back to Boston.
●
The trace indicates that somewhere in the local Boston area the multicast tree is affected,
affecting about 1400 subscribers.
●
The operator uses Cisco ANA to analyze the status of routers serving the local Boston
area.
●
Cisco ANA detects routing protocol issues and isolates the affected router.
●
The operator resets the router either through Cisco ANA or through direct interaction. The
multicast route rebuilds in less than one second, and service quality returns to normal
standards.
●
In parallel with this repair process, the operator sends a message to the help desk about
the incident and the affected channels, and informs the help desk when the problem is
fixed.
●
Using Cisco VAMS, the event is reported, correlated, isolated, and fixed before the
subscriber in Boston has time to call the provider to complain, and the playoff party
resumes.
Cisco VAMS: An Extensible Framework
Cisco VAMS offers service providers the comprehensive, integrated fault management system
they need to manage video quality in IP broadcast television networks. The scalable, extensible
platform accommodates network growth and easily integrates new technologies, giving Cisco
VAMS both longevity and a strong return on investment. Cisco continues to extend the platform
capabilities over time to meet the IP transport management requirements of its video service
provider customers as they compete for ad revenues and subscribers in the lucrative television
industry.
