It’s 2AM, the network is down, and the CEO is on the phone asking when it is going to be back up—the overnight job crucial to the business opening in the morning has failed, and the company stands to lose millions of dollars if the network is not fixed in the next hour or so. Almost every network engineer has faced this problem at least once in their career, often involving intense bouts of troubleshooting.
And yet—troubleshooting is a skill that is hardly ever taught. There are a number of computer science programs that do include classes in troubleshooting, but these tend to be mostly focused on tools, rather than technique, or focused on practical skill application. I was also trained in troubleshooting many years ago as a young recruit into the United States Air Force—but the training was, again, practical in bent, with very few theoretical components.
Note to readers: I wrote a short piece on troubleshooting here on rule11, but I have taken that piece down and replaced it with this short series on the topic. I did start writing a book on this topic many years ago, but my co-authors and I soon discovered troubleshooting was going Continue reading

We’re excited to announce the release of Cumulus Linux 3.3! This product update was designed to enhance the performance and usability of your network. This release includes several enhancements to many existing features, like NCLU and EVPN, as well as brand new features, like buffer monitoring, PIM-SSM, 25G support and more, for increased reliability. The following paragraphs cover the key updates in this release.
Proactively detect congestion events that result in latency and jitter by monitoring traffic patterns to identify bottlenecks early and effectively plan for capacity. This new feature available on Mellanox hardware alerts for congestion & latency thresholds, helping you understand traffic patterns and model network operations based on buffer utilization data.
Ideal for customers using latency Sensitive Apps such as for HFT, HPC, distributed in-memory apps, buffer monitoring will allow you to proactively detect congestion events that result in latency and jitter by monitoring traffic patterns to identify bottlenecks early and effective plan for capacity.
Get Source-Specific Multicast for more efficient multicast traffic segmentation and higher scalability.
Having intermittent sources is a common issue when market data applications are used as servers to send data to a multicast group and then go silent Continue reading
