Three major data transmission challenges are highlighted: burstiness, high loss cost, and traffic congestion. Can you explain why increased link capacities amplify traffic burstiness, and what specific impacts does this burstiness have on WAN performance (e.g., flow completion time, resource utilization)?
Thank you for your question. When link capacities increase, the physical time it takes to serialize and transmit a fixed amount of data shrinks dramatically. For examples, if an AI application needs to send a 1 GB payload over a 1 Gbps link, it takes 8 seconds of sustained, relatively steady traffic. If that link is upgraded to 100 Gbps, that same 1 GB payload hits the network as a massive spike lasting just 0.08 seconds.Traffic burstiness creates a mismatch between average bandwidth and instantaneous demand,which causes congestion and packet loss. It can bring Poor Network Resource Utilization, Degradation of End-to-End Goodput and Volatile Flow Completion Times to WANs performance.
