During yesterday's LibreQoS APNIC webinar, I posed the question: won't more bandwidth solve these problems? As Herbert Wolverson said, yes, more bandwidth is good, but, still these problems remain if queueing is done incorrectly. Here's my take on why bandwidth alone is not as good as bandwidth good queueing policies: Generally it was believed that 'data is important, so don't throw it away; hang on to it and send it later'. In practice, this has proven to be suboptimal as two issues may emerge: 1) latency increases for some flows due to heavy demand from other flows using the same bottleneck link, 2) even a single flow can have excessive latency due to aspects of typical TCP behavior (referred to bufferbloat) when the buffers grew large enough that the data being buffered was retransmitted anyway. It turns out that not all data is equally important. Active Queue Management is the art of deciding priorities, both in deciding what data to throw away, but also in allowing some later arriving data to be transmitted ahead of data in another connection that arrived before it. These problems have been studied, and good solutions have been found by using certain queueing policies in routers and switches, referred to as “fq_codel’ and “cake”. These track the different flows not by classifying the data, but by watching the behavior. Flows that send relatively little data (DNS lookups), or at a measured pace (video chat) have priority over flows that send a lot of data as quickly as possible (App and System updates, Video and ISO downloads).

🎉 Excited to share as an indirect investor that DevRev, backed by Khosla Ventures, has officially become a unicorn. Dheeraj Pandey, CEO at DevRev, puts it perfectly: "At the end of the day, every developer is either building something new or fixing something related to the product. But inefficient systems and processes keep developers further from their consumers. We believe there's a better way to build, operate, support, and grow your business through code. That's why we've embarked on a journey to create the Developer Customer Relationship Manager (DevCRM) that we hope will help makers build the most customer-centric companies on earth." Here are some key points about DevRev: - Co-founded by Dheeraj Pandey (co-founder of Nutanix) and Manoj Agarwal (former SVP of Engineering at Nutanix). - Offers three modern CRM apps tailored for support, product, and growth teams. - Already making waves in Southeast Asia. If you're in the region and have questions, reach out to Jeffin Mathew. 💡 Fun fact: Nutanix was also backed by Khosla Ventures. Congratulations to the entire DevRev team on reaching this incredible milestone in under 4 years! I'm thrilled to be part of the journey as a Limited Partner in 2 | Twelve one of their seed investors.
