Hi all, in our paper "Policy-oriented AQM Steering" that will be published at Networking 2018 shortly, we used also plain GSP and CoDel for comparison. Maybe this is convincing enough that GSP is also worth to be considered as alternative. We especially found it much easier to implement AQM Steering for GSP since GSP's implementation is simpler than others. The basic idea of AQM Steering is to modify the delay target setpoint of the AQM in order to adapt to the current traffic situation: Depending on the traffic the same setpoint value can result either in unnecessary large delays or under-utilization of the link. Policy-oriented AQM Steering automatically adapts the target delay setpoint to the current traffic situation, in order to fulfill a given quality-of-service policy. Such a policy consists of a utilization goal and an upper delay bound. This improves AQM performance with varying traffic situations and makes the impact of deploying an AQM predictable. A prototypical implementation of AQM Steering for GSP showed its performance advantages compared to static AQM variants at speeds of 10 Gbit/s and 1 Gbit/s.

It performs extremely well in some settings (better than CoDel or PIE) and its implementation complexity is also lower. Wolfram, are you interested in finishing this? > Should we continue in tsvwg?
