Views: 2,550This question was sent to me in an email following my posts on regarding TCP CUBIC. The answer is Yes—Microsoft Windows does support TCP CUBIC, but the nuance is in how and when it’s used. For many years, Windows defaulted to Compound TCP (CTCP) rather than CUBIC. Meanwhile, Linux distributions standardized on TCP CUBIC,

Views: 1,747I described what Adaptive Bit Rate Streaming (ABR) is in my prior article, if you need that background. Also there is an ABR Lab Exercise if you want some hands on learning with ABR that will show you visually some of the items discussed below. Here, I wanted to dive a little deeper into

Views: 4,186Most people do not know this, but TCP CUBIC is the dominant congestion control algorithm used in modern TCP/IP networks. It is designed to efficiently utilize high-speed, long-distance links while maintaining fairness across flows with different round-trip times (RTTs). Today, it is the default congestion control algorithm in most Linux systems, and since most

Views: 9,533So often in Wireshark videos and classes we spend a lot of time on TCP behavior. But what I am about to discuss is hardly ever brought up. The answer to flavor is simple right? The truth is that there are multiple “flavors” of TCP, and TCP does not have a version number in
