❓ Frequently Asked Questions
What is Wireshark?
Wireshark is a network protocol analyzer that captures live traffic or reads pcap files, decodes protocols, and helps troubleshoot issues.
What is a packet broker?
A packet broker aggregates traffic from multiple taps, filters/duplicates it, and routes it to monitoring tools for scalable visibility.
What is SDN?
Software-Defined Networking centralizes control in software, decouples the control and data planes, and enables programmable, dynamic network management.
What is the difference between capture filters and display filters in Wireshark?
Capture filters decide which packets are recorded (applied at capture time); display filters refine what you see after capture.
