Post Views: 587 MPTS stands for Multi-Program Transport Stream. It is a format defined within MPEG-2 Transport Stream (MPEG-TS) standards where multiple independent programs (channels) are multiplexed into a single transport stream. A simple definition would be one MPTS carries multiple programs with each program containing a complete service of video plus audio plus metadata.

Post Views: 605 Do not troubleshoot Wireshark captures by chasing random red and black packets. Start with triage, classify the traffic, branch into the correct protocol workflow, and then prove the finding with packet evidence. The following is a shortened version of our structured “Triage → Classify → Branch → Prove” Wireshark troubleshooting workflow built

Post Views: 2,274 Learning 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

Post Views: 865 Net 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
