Stretching Elasticity: Traffic Peak Management in an Efficiently Designed Telco-CDN 

Published On: April 14, 2023Categories: ,

When building a Telco-CDN infrastructure, Internet Service Providers (ISP) first consider the peak throughput and then provision the infrastructure as a function of peak capacity. New network design practices indicate that instead, operators would benefit from dimensioning the infrastructure to cover the traffic demand for a fraction of time, and develop strategies to manage the peaks, which happen when the demand exceeds the capacity of the infrastructure. A peak offloading strategy is particularly effective in online video delivery where demand peaks, often driven by sports events, are transient and significantly higher than average traffic. This paper provides a tour of CDN management, described by a new approach to design Telco-CDN with greater fluidity, mixing appropriate technologies to provide the right elasticity at the right time.
