Challenge 7: Precedence of Elastic Traffic Elastic traffic adapt to available bandwidth via a feedback control loop such as the TCP congestion control. Two types of "as-soon-as-possible" traffic types: short-lived flows e.g. HTTP flows with an expected average throughput e.g. FTP For all those flows the application dynamically adjusts the data generation rate but elastic data applications can show extremely different requirements and traffic characteristics. Idea: distinguish several classes of best-effort traffic would be beneficial to address the relative delay sensitivities of different elastic applications |
