Conclusion
Recap
- Loss-based TCP fills queues and induces packet loss
- Delay-threshold based TCP relies on baseRTT
Our use of delay-gradient as congestion indication:
- Avoids the need for an accurate estimate of baseRTT
- Can be used to help tolerate non-congestion losses
- Can coexist (mumble) with loss-based TCP
- Lots of future work on hybrid congestion control algorithms, evaluating CDG's detailed dynamic characteristics, ....
- Implemented in FreeBSD kernel
