Nichols and Jacobson have recently released a paper on ACM Queue which outlines their new AQM called Codel. At a very high level Codel can be thought of as a self tuning RED. This is a very interesting development and I look forward to testing it on my Internet connection. The paper is worth reading just for some of the insights into network behavior.

Also, Jonathan Morton provides a good summary of what’s novel about Codel on the Bufferbloat list.
