Bandwidth Provisioning with Flow-level Traffic Measurements

Description of research

An important task for network operators is to properly provision the capacity of their network links. Often, this is done by rules of thumb based on coarse measurements, provided, e.g., by SNMP (Simple Network Management Protocol). More accurate bandwidth estimation procedures typically require packet-level measurements, which are hard to implement in today’s high-speed networks. The challenge is, therefore, to accurately estimate the traffic statistics needed for bandwidth estimation, without the burden to perform packet-level measurements.

This PhD will investigate how to perform bandwidth provisioning using flow-level traffic measurements. The goal is to propose an accurate and easy-to-deploy flow-based procedure for bandwidth provisioning and validate it using real-world traffic captures from backbone networks.
