Good News for Solving Bufferbloat: CoDel Provides “No Knobs” Solution
May 8th
Data transfer speeds have been getting faster and faster, but that doesn’t mean that we’re actually reaping the full benefits. A few years ago, Jim Gettys put his finger on the “criminal mastermind” behind poor networking performance. Dubbed Bufferbloat, the problem was not a simple one to solve. Not simple, but Controlled Delay (CoDel) active queue management (AQM) may provide serious progress towards a solution.
The problem, in a nutshell, is that TCP was not designed with today’s bandwidth in mind. As Gettys wrote in “the criminal mastermind” post, the problem lies “end-to-end” in applications, operating systems and home networks. Buffering is necessary, but too much buffering is a problem. And today’s devices and operating systems are doing too much buffering – which is degrading performance. Says Gettys, “TCP attempts to run a link as fast as it can, any bulk data transfer will cause a modern TCP to open its window continually, and the standing queue grows the longer a connection runs at full bandwidth, continually adding delay unless a AQM is present.”
The Linux Tips page on the Bufferbloat wiki highlights the scope of the problem. According to the page, buffers can “hide” in the operating system layer (Linux transmit queue), device driver, hardware (which has buffers of its own), and on and on. One of the long-term solutions to bufferbloat is active queue management (AQM), and the Controlled Delay (CoDel) AQM proposed by Kathleen Nichols and Van Jacobson might be a big piece of the puzzle.
CoDel To the Rescue?
CoDel (pronounced “coddle”), is being called a “no-knobs” AQM. That means users and admins aren’t expected to tweak any parameters to get best performance out of CoDel. According to the paper published on ACM Queue, “CoDel’s algorithm is not based on queue size, queue-size averages, queue-size thresholds, rate measurements, link utilization, drop rate or queue occupancy time. Starting from Van Jacobson’s 2006 insight (PDF), we used the local minimum queue as a more accurate and robust measure of standing queue.”
More importantly, CoDel promises to distinguish between “good” queues and “bad” queues. It’s supposed to minimize delay without hampering bursts of traffic. “The core of the bufferbloat-detection problem is separating good from bad … good queue is occupancy that goes away in about one RTT (round-trip time); bad queue persists for several RTTs. An easy, robust way to separate the two is to take the minimum of the queue length over a sliding time window that’s longer than the nominal RTT.”
Finally, CoDel is supposed to be suitable for deployment in a wide range of devices. The paper says CoDel is “simple and efficient,” and can be deployed in low-end devices or “high-end commercial router silicon.”
Proof is in the Pudding, er, Deployment
A fair amount of testing has been done on CoDel, but the proof has to come via real-world deployments. According to the paper, Nichols and Jacobson performed “several thousand simulation runs” that showed CoDel “performed very well” with results “compelling enough to move on to the next step of extensive real-world testing in Linux-based routers.”
Note that deploying this in a home-based router may not be enough to rid yourself of bufferbloat. The researchers point out “a savvy user could be tempted to deploy CoDel through a CeroWrt-enabled edge router to make bufferbloat disappear. Unfortunately, large buffers are not always located where they can be managed but can be ubiquitous and hidden. Examples include consumer-edge routers connected to cable modems and wireless access points with ring buffers. Many users access the Internet through a cable modem with varying upstream link speeds. … The modem’s buffers are at the fast-to-slow transition, and that’s where queues will build up: inside a sealed device outside of user control.”
So, don’t expect CoDel to solve the bufferbloat problem overnight, or even by the end of the year. Gettys says that “work to integrate adaptive AQM algorithms into wireless systems work will take months or years, rather than the week that initial CoDel prototype implementation for Ethernet took. But at least much testing of the CoDel algorithm, experimentation, and refinement can now take place.”
There’s also the matter of tackling wireless, which Gettys says “may be much more difficult, both because queuing is sometimes much more complex than Ethernet, but also since packet aggregation has resulted in OS/driver boundaries hiding information that is necessary for proper functioning.”
But CoDel is still very good news, and shows that the community that’s come together around the bufferbloat problem is making progress. Bufferbloat won’t be solved in one fell swoop by a single breakthrough, but with a number of technology improvements over time.

Good News! Angels Are Getting More Optimistic
Apr 26th
If you’re looking for angel investors, there’s good news afoot. The latest 2011 Angel Market Analysis, recently released by the Center for Venture Research at the University of New Hampshire, shows not only that there are more angels around, but that they are investing more money in more companies.
Here’s a closer look at what angels are thinking and doing – and some ideas on how you can leverage their growing confidence to fund your business.
Overall, angel investments in 2011 reached $22.5 billion, 12.1% more than in 2010. About 66,230 entrepreneurial businesses got angel funding in 2011, up 7.3% from 2010. Finally, 2011 saw 20% more active investors (318,480 in all) compared to 2010.
“Angels have significantly increased their investment activity, and are committing more dollars resulting from higher valuations,” says Jeffrey Sohl, director of the UNH Center for Venture Research at the Whittemore School of Business and Economics. “It appears that an optimism in angel investing is taking hold.”
How can you benefit from this optimism?
Act quickly. If you’re looking for seed or startup capital, the time to make your move is now. The study found angel interest in early-stage investing is growing. Last year, 42% of angel investment was seed and startup capital, reversing a two-year decline in the percentage of angel capital going to early-stage companies.
Target your approach. Obviously, looking for angels who specialize in your industry increases your chances of success. Last year, software was the most popular sector, attracting 23% of total angel investments, followed by health care services/medical devices and equipment (19%), industrial/energy (13%), biotech (13%), IT services (7%), and media (5%). Industrial/energy investing has remained a significant sector for angels for the past few years, reflecting a continued appetite for clean tech.
Be optimistic, but not unrealistic. Share your angels’ optimism by showing how your business will succeed, grow and give them the rate of return they’re looking for. But don’t promise the moon or try to fly by with unrealistic financial projections or fantasies of dominating the marketplace. Yes, angels may be feeling more confident, but they’re not wearing rose-colored glasses.
If your business is beyond the seed capital stage, there’s still good news for you. Businesses in the early and expansion stages received 55% of angel investments, which, although down from 67% in 2010, is still substantial. New, first-sequence investments represented 52% of 2011 angel activity, an increase of 11% from last year.
Sohl sees this as a good sign for young businesses. “This increase in seed/startup stage and first sequence investing is promising, and this renewed interest in seed and startup financing is an encouraging development for our nation’s entrepreneurs,” he says.
It’s also a good thing for America. Angel investments last year were a significant contributor to job growth, leading to the creation of 165,600 new jobs, or 2.5 jobs per angel investment.
