Managing fairness and application performance with active queue management in docsis-based cable networks

Abstract

We evaluate modern delay-based AQM algorithms in downstream DOCSIS 3.0 cable environments. Our focus is on fairness and application performance capabilities of two recently proposed delay-based AQM algorithms, CoDel and PIE. The evaluation involves scenarios that include tiered service levels and application workloads that include FTP, HTTP-based adaptive streaming, and VoIP traffic. Our results provide a snapshot of our current effort to evaluate AQM schemes that are likely to be deployed in emerging DOCSIS cable networks.
