Extracting VoIP Packets from Multiple Captures

Networking and Computing Tips and Tricks / By

Views: 1,270Let’s say you are a CO Tech/Engineer or an enterprise network engineer that works with Voice over IP (VoIP). Let’s further say that there are issues with one or more users so you have done a bunch of packet captures, perhaps even used Wireshark’s Ring Buffer capability, and now you want to extract from

How to Set a WLAN Frequency or Channel in Linux for Wireshark Packet Capture

Networking and Computing Tips and Tricks / By

Views: 3,064Learning how to manually control Wi-Fi channels in Linux is a foundational skill for wireless troubleshooting and packet analysis. Proper channel selection is critical because Wi-Fi troubleshooting is highly dependent on capturing the correct RF environment at the correct moment in time. When combined with Wireshark, Linux monitor mode provides one of the most

Net Neutrality at the Packet Level

Networking and Computing Tips and Tricks / By

Views: 1,034Net neutrality is typically framed as a policy debate (see my background Net Neutrality post here), but its real implications are observable in packet-level behavior. For network engineers and broadband technicians, the question is not abstract: can you see evidence of blocking, throttling, or prioritization in a packet capture? To read more – visit

Mapping ABR to TCP Congestion Control and QUIC

The CellStream Blog / By

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

What Is Adaptive Bitrate Streaming (ABR)?

The CellStream Blog / By

Views: 2,039Adaptive Bitrate Streaming (ABR) is a video delivery method that dynamically adjusts the quality of a stream in real time based on three things: network conditions, device capability, and player performance. Instead of delivering a single fixed-quality, and therefore fixed transfer rate video, ABR continuously selects the most appropriate bitrate to maintain smooth playback

What is TCP CUBIC and Why so popular?

The CellStream Blog / By

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

The TLS 1.2 Protocol Ladder

Networking and Computing Tips and Tricks / By

Views: 2,541I provide this information for reference when examining TLS in Wireshark. The TLS 1.2 protocol ladder (also called the TLS handshake ladder) describes the step-by-step sequence of message exchanges between a client and server as they negotiate a secure, encrypted connection. Think of it as a “ladder” where each side alternates rungs (messages) upward

What is the Adapter for loopback traffic capture in Wireshark?

Networking and Computing Tips and Tricks / By

Views: 10,601Using a loopback adapter (also called a local loopback interface) for packet capture in Wireshark allows you to capture traffic that stays within your own computer — for example, packets exchanged between local applications via localhost or 127.0.0.1. Normally, this traffic never reaches a physical network interface, so a loopback capture is needed to
