Post Views: 113,317 TCP Delta Time refers to the time difference between consecutive Transmission Control Protocol (TCP) packets in a data transmission. It is an important metric when analyzing network performance for several reasons: 1. Network Latency and Performance High Delta Times: When the delta time between TCP packets is high, it may indicate network […]

Post Views: 92,001 TCP Sequence analysis is critical in network troubleshooting because it provides insights into the flow and order of data being transmitted over a network. Here’s why it plays such a crucial role in diagnosing network issues: 1. Ensuring Data Integrity and Order TCP Sequence Numbers: TCP assigns sequence numbers to each byte

Post Views: 2,126 TCP Selective Acknowledgment (SACK) analysis is crucial for troubleshooting network performance and reliability because it provides enhanced mechanisms for handling packet loss, retransmissions, and improving overall efficiency of TCP communications. Here’s why TCP SACK analysis is important in network troubleshooting: 1. Handling Packet Loss More Efficiently Traditional Acknowledgment (ACK) vs. SACK: In

Post Views: 8,313 This ZIP file contains and example of an IPv6 TCP SYN flood attack. A SYN flood is a denial-of-service (DoS) attack that exploits the TCP three-way handshake by overwhelming a target with a large volume of SYN (synchronize) packets, causing the target to exhaust connection resources and become unable to serve legitimate

Post Views: 5,157 Inspired by fellow troubleshooters, this simple TCP profile is often a good way to scan captures trying to find pattern changes. For detailed troubleshooting we would then switch to out other TCP profile. But check this out!

Post Views: 88,641 Most network engineers and technicians are quickly discovering that with “everything over IP” we are required to understand exactly what this means. For a lot of the standard, traditional data communications between clients and servers this means transport over TCP. Furthermore, it requires the ability to troubleshoot TCP. To troubleshoot TCP you

Post Views: 17,641 Thanks to your comments! Enjoy! Most network engineers and technicians are quickly discovering that with “everything over IP” we are required to understand exactly what this means. Traditionally, for most data communications this means transport IPv4 over TCP (although QUIC over UDP is gaining major momentum). We are finding that IPv6 represents
