Estimating an Additive Path Cost with Explicit Congestion Notification (extended version)
University of Oslo, 2019.Status: Published
Estimating an Additive Path Cost with Explicit Congestion Notification (extended version)
Abstract—Network Utility Maximization (NUM) is a well accepted theoretical concept that describes how congestion controls could cooperate to achieve an ideal sending rate allocation, for given utility functions of senders and constraints of the network. These network constraints are expressed as a “cost” in the framework. In practice, most congestion control mechanisms obtain feedback that is different from a “cost”. This paper focuses on Explicit Congestion Notification (ECN), which has been shown to be quite advantageous when it is available, e.g. with the popular Datacenter TCP (DCTCP) mechanism. However, different from a cost, ECN marks are not additive. We present a practical solution to this problem. Our solution changes how end hosts interpret the ECN signal, while the router side can be implemented via an unusual configuration of RED parameters.

AQM Characterization Guidelines
IETF, 2016.Status: Published
AQM Characterization Guidelines
Unmanaged large buffers in today's networks have given rise to a slew of performance issues. These performance issues can be addressed by some form of Active Queue Management (AQM) mechanism, optionally in combination with a packet scheduling scheme such as fair queuing. The IETF Active Queue Management and Packet Scheduling working group was formed to standardize AQM schemes that are robust, easily implementable, and successfully deployable in today's networks. This document describes various criteria for performing precautionary characterizations of AQM proposals. This document also helps in ascertaining whether any given AQM proposal should be taken up for standardization by the AQM WG.

Alternative Backoff: Achieving Low Latency and High Throughput with ECN and AQM
Melbourne, Australia: Centre for Advanced Internet Architectures (CAIA), Swinburne University of Technology, 2015.Status: Published
Alternative Backoff: Achieving Low Latency and High Throughput with ECN and AQM
CoDel and PIE are recently proposed Active Queue Management (AQM) mechanisms that minimize the time packets spend enqueued at a bottleneck, instantiating shallow, 5 ms to 20 ms buffers with short-term packet burst tolerance. However, shallow buffering causes noticeable TCP performance degradation when a path’s underlying round trip time (RTT) heads above 60ms to 80ms (not uncommon with cross-continental and inter-continental traffic). Using less-aggressive multiplicative backoffs is known to compensate for shallow bottleneck buffering. We propose ABE: “Alternative Backoff with ECN”, which consists of enabling Explicit Congestion Notification (ECN) and letting individual TCP senders use a larger multiplica- tive decrease factor in reaction to ECN-marks from AQM- enabled bottlenecks. Using a mix of experiments, theory and simulations with standard NewReno and CUBIC flows, we show significant performance gains in lightly- multiplexed scenarios, without losing the delay-reduction benefits of deploying CoDel or PIE. ABE is a sender- side-only modification that can be deployed incrementally (requiring no flag-day) and offers a compelling reason to deploy and enable ECN across the Internet.
