Impact of Network Conditions
on Video Broadcasting

with Calnex Solutions and Spirent Communications

Tuesday 27th October 11:00am Central European Time

Most of today's broadcasting is done over IP networks. These networks are not perfect - they can suffer from overload at peak hours, weather perturbations and other factors that impact the capacity of the network. When it comes to near real-time usages, such as Video Broadcasting, the effects can be immediate and usually result in some form of quality degradation. It's important for Service Providers to understand how these perturbations impact their users' Quality of Experience ; and it's better to find out in the development phases rather than in production. This talk illustrates the impact of network conditions using traffic generators and network impairment devices that realistically emulate real life conditions and behavior.
